For example, the Inputs section is maximized with all processor blocks and the mix‑points shown. Clicking the button in this example shrinks the view to its minimum screen area allowing items below to fill the screen. b Maximize buttons — Click to toggle the view of a selected section from maximum to minimum.
a b c d e f g l m h j i k Figure 14. DMP 128 DSP Configurator Main Screen The DSP Configurator program screen consists of an input and virtual return signal processor chain, the mix-points, and an output signal processing chain. The main mixer is separated into segments as shown in figure 14. NOTE: The expansion bus input mix-points are not shown in this view.
Cut, Copy, or Paste Functions The user can cut, copy, or paste a processor. These actions can be performed from a context menu accessed by a right-click on the processor block, using the Edit menu, or using the standard Windows keystrokes: = cut; = copy; = paste. Multiple elements may be acted upon but the blocks copied must be compatible with the desired paste blocks. A highlighted group of elements can be cut or copied to a clipboard.
Click Yes. The entire Mic #4 input path is now identical to the Mic #1 input path including signal levels, parameters settings, and mute/bypass selections. Any single processor block is copied, then pasted to a similar processor block in the same or different input, virtual or output signal path. Mix‑point gains can be copied from one to another. Input gain, pre‑mixer gain, post-mixer trim, and output volume can only be copied to like gain blocks.
DSP Configurator Toolbar Menus The DSP Configurator contains the following menu bar, arranged horizontally below the title bar: • File • Edit • View • Tools • Window • Help File NOTE: New, Open, and Recent Files are unavailable in Live mode. • New — Discards the current DSP configuration (after prompting to save changes) and opens a blank configuration file. • Open — Loads and activates a previously saved DSP configuration file.

Level Control Blocks To access a gain, trim or volume control to view a setting, make a change, or observe a live audio meter (input gain and output volume blocks only), double‑click the gain block icon (see figure 18). This action opens a dialog box that contains the fader for that control. Double-click a gain, trim, or volume control. A dialog box opens, containing the full fader control. NOTE: In Emulate mode (the startup mode), the meter is not operational. Figure 18.
Once a processor is inserted, to view associated parameters that define the selected processor (such as a frequency curve) or to remove the bypass, double‑click the processor block. This action opens a new dialog box with parameters for the process (see figure 20). Figure 20. Sample Processor Dialog Box • Click Set Defaults to discard all custom settings and reload the default parameters. • Click Bypass to temporarily suspend processing without removing the processor block.
Mic/Line Input Signal Chain Controls The input signal processor chain allows adjustments to program or microphone audio material before input to the main mixer. Gain Control (GAIN) The gain control provides a single long-throw fader with a range of – 18 dB to +80 dB, adjustable in 1 dB increments with the fader or in 0.1 dB increments using direct entry in the level setting readout below the fader.
• Low pass filter — A low pass filter passes a band of frequencies extending from a specified cutoff frequency (less than infinite) towards the lower end of the frequency spectrum. All frequencies below the specified frequency are allowed to pass, while all frequencies above are attenuated. The default cutoff is 10 kHz.
Figure 23. Filter Dialog Box, Filters Added Within the dialog box, a filter is focused when a filter type is inserted, or is focused by clicking the filter number to the left of the filter selection drop-down list. Note the box number in row 3 in figure 23 is highlighted in yellow, indicating it is the filter in focus. The results of the filter in focus (independent of other filters) show in the graph as a dotted line the same color as its filter row when bypassed.
Figure 24. Filter Dialog Box, Filter Not Bypassed Above the graph, each filter has a "handle" (circled in red above) placed directly above the cutoff or center frequency whose number corresponds to the filter number (outlined in red). Click a handle or click the table row to bring focus to that filter. Click+hold+drag the handle horizontally to change the cutoff or center frequency. The table below shows each filter type with default parameter settings.
High Pass The high pass filter allows all frequencies above the specified cutoff frequency to pass unattenuated. All frequencies below the cutoff are attenuated. The default cutoff is 100 Hz. Figure 25. High Pass Filter Response Curve In figure 25, all frequencies lower than the specified frequency, 100 Hz, are attenuated leaving the upper frequency response flat. Also note at the specified frequency (100 Hz), the signal is about 3 dB down, typical operation for high pass filters.
Low Pass The low pass filter is the opposite of the high pass filter. All frequencies above the specified frequency are attenuated allowing lower frequencies to pass. The default cutoff is 10 kHz. Figure 26. Low Pass Filter Response Curve Here, the frequencies higher than the specified frequency, 10 kHz, are attenuated leaving the lower frequency response flat.
Bass and Treble Shelving Bass and treble shelving can be added to the filter. Known as shelving or tone controls, the separate bass and treble filters provide the ability to cut or boost gain linearly above or below a selected frequency, with the end-band shape giving the visual appearance of a shelf. If only a bass or only a treble filter is required, either bypass the unneeded control or set it to Unused in the selection box. The bass default frequency is 100 Hz and the treble default is 8 kHz.
Parametric (Equalizer) The parametric filter is a frequency equalizer that offers control of all parameters, including amplitude (the amount of gain [boost], or gain reduction [cut] applied), center frequency (frequency), and range of affected frequencies (Q) around the center frequency. Q is the center frequency divided by the bandwidth. Up to five parametric filters can be placed in the filter block at one time, each set to a different frequency creating a five band parametric equalizer.
By increasing the Q to 10.000, the center frequency remains the same. The markers show the bandwidth of the filter narrowed to between 900 Hz and 1200 Hz, or about 300 Hz (see figure 29). Using the Q value, parametric filters can be used to notch out a very narrow, or very wide range of frequencies. Figure 29. Parametric Filter at 1000 Hz, Q: 10.000 The dialog box above shows the frequency curve for a single active filter.
The overall frequency response is now shown as a solid red line with the filter in focus located in row 3 (see figure 30 below) shown in the color of its table row. Figure 30. All Parametric Filters Active The parametric filter allows frequency selection accurate to 0.1 Hz and either 6 or 12 dB of slope.
Acoustic Echo Cancellation (AEC) The DMP 128 C models provide one acoustic echo canceller processor for each of the first eight mic/line inputs. A single reference can be selected for each AEC from a list of the twelve line inputs. About AEC Echo occurs when audio from a talker in the far end is received and amplified into the near end listener’s room, with that sound then being picked up by microphones in the near end acoustic space and sent back to the far end.
When using an output channel as a reference, the reference point is post volume control; therefore, changes to the listening volume in the room affects the AEC gain structure (see AEC Dialog, below). If you have an output channel on the DMP 128 that is not being used, you can isolate the reference channel from the channel being used for volume control by routing reference signals to the unused output channel.
Meters • ERL – the ratio in dB between the signal at the reference and the signal at the AEC channel input. When ERL is a positive number, the signal level at the AEC channel input is lower than the signal at the selected reference (0 to +15 dB is desirable). • ERLE – the amount in dB of potential echo signal that the AEC algorithm, not including NLP processing, is cancelling. • TER – the sum of ERL + ERLE, in dB.
Advanced AEC Controls Click on the open/collapse icon at the bottom of the AEC dialog to reveal the advanced AEC controls. Advanced control functionality is as follows: Non-linear Processing (NLP) Controls • Enable NLP — this box is selected by default. NLP is necessary for the removal of echo. • NLP Presets — click a button to load a set of values to the three NLP parameters; Max NLP Reduction, Attack Time, and Release Time.
Dynamics (DYN) A dynamics processor alters the dynamic range, the difference between the loudest to the quietest portions, of an audio signal. Each input channel provides two dynamics processor blocks that, when inserted, provide one of four types; AGC, Compressor, Limiter, or a Noise Gate processor. Once a processor has been inserted, individual processor parameters can be changed in the dialog box, accessed by double‑clicking the processor block.
AGC (Automatic Gain Control) AGC adjusts the gain level of a signal based on the input strength to achieve a more consistent volume. Below the set threshold, the signal is not affected. Above the threshold, weaker signals are boosted up to the maximum gain setting to reach a user‑defined target level. As the signal level approaches the target level it receives less gain or no gain at all. Once the signal level reaches the target level all gain is removed.
Compressor The compressor regulates signal level by reducing, or compressing, the dynamic range of the input signal above a specified threshold. The input level to output level ratio determines the reduction in the dynamic range beyond the threshold setting. For example, with a ratio setting of 2:1, for every 2 dB of input above the threshold, the compressor outputs 1 dB. Compression is commonly used to contain mic levels within an acceptable range for maximum vocal clarity.
Limiter The limiter restricts the input signal level by compressing its dynamic range above a specified threshold. The limiter is most commonly used to prevent clipping, protecting a system against component or speaker damage. While the limiter is closely related to the compressor, it applies a much higher compression ratio of ∞:1 above the threshold. The ratio is fixed and cannot be changed. Click in each field or use the sliders to change the values.
Noise Gate The noise gate allows an input signal to pass only when it exceeds a specified threshold level. Above the threshold level, the signal passes unprocessed; below the threshold the signal is attenuated at the rate set by the ratio adjustment. The typical setting of the noise gate threshold is just above the noise level of the environment or source equipment. That allows signals that are above the noise to pass, and attenuates the noise when there is no signal to eliminate background noise.
Delay (DLY) The delay processor block, when inserted, provides a means to delay the audio signal. Audio delay syncs audio to video or can time-align speakers that are placed at different distances from the listener. The DMP 128 can set delay by either of two criteria: time or distance (feet or meters). The default unit setting is time with a range of 0.0 ms to 200.0 ms adjustable in 0.1 ms steps. Default is 100.0 ms. Settings are controlled with a vertical slider and indicated in the readout field.
Ducking Ducking provides a means to duck, or lower, the level of one or more input signals when a specified source must take precedence. The ducking processor block, when inserted, provides a means to duck one or more mics and program material (ducking targets) when the processor detects a signal from the ducking source.
Ducking Configuration Ducking is configured in a dialog box that opens when an active ducking processor block is double-clicked. a Current Source Shows the input selected as the ducking source. Ducker settings affect the input channel shown here. When a ducker dialog is opened, the current source defaults to that channel. The current source can also be selected via the priority readout/source selector (see below).
Priority In some cases, multiple levels of ducking can be required to enable an input source to take precedence over all but one other input. In this example, Inputs 2 through 6 are set to duck when Input #1 has a signal above the ducking threshold. Input #2 is set to duck inputs 5 and 6. Since Input #1 has previously been set to duck Input #2, Input #1 is disabled to prevent contradictory priorities. Figure 32. Ducker Configuration, Input Priority Notice the priority tree on the right side of figure 32.
Ducker Tutorials The examples below are based on different input configurations. Insert a ducker from a ducker processor block using one of the following methods: Double-click the block, then click Ducker -or- Right-click the box to open context menu, then click Insert Ducker Once inserted, double-click on the ducker block to open the ducker configuration dialog box. The Enable Mic/Line Source box is checked. Ducking and Priority Ducking The first inserted mic ducks all selected targets.
Automix (AM) An automixer manages multiple microphone sources, gating or varying input gain automatically. When properly set, the automixer system will improve use and performance when multiple mics are in use. The two basic types of automixer include gated and gain-sharing. A gated automixer attenuates an input channel when the signal level drops below a user‑defined threshold. DSP Configurator allows the user to divide these automixers into gating groups.
• Off Reduction — The channel attenuation when a mic channel gates off. Range is 0.0 dB to 100.0 dB attenuation (0 to – 100 dB). Default: 60.0 dB. • Attack Time — Sets the time at which gain is applied after a channel gates on. Range is 0.0 msec to 3000.0 msec in 0.1 msec increments. Default: 10.0 msec. • Hold Time — The time that a mic remains active after the signal drops below a user‑defined threshold. Range is 0.0 msec to 10000.0 msec in 0.1 msec increments. Default: 400.0 msec.
Automix Groups Assigning individual automix channels to groups allows you to see and adjust all channels assigned to the group on one page. The automix group dialog provides details of all grouped and ungrouped inputs including the automix settings of each channel or mic. This provides an overview of all channels in the selected group at a glance. Individual settings can be changed without leaving the groups dialog.
Configuring an Automix Channel Before configuring automix, Extron recommends that you set proper gain staging for the input mics. This ensures that adequate signal is provided for automix to work properly. An automix block is inserted for each microphone, and the mic assigned to a group (see figure 33, Automix Groups Dialog on the previous page).
Telephone Rx (DMP 128 C P and DMP 128 C P AT only) Figure 36. Telephone Rx Signal Path The DMP 128 provides a telephone interface with separate input and output signal processing paths. The telephone input (Rx) is identical to the other input processing paths except the AEC block is not used. See Telephone Interface on page 126 for additional information. NOTE: The country code must be entered before connecting the DMP 128 to a phone system. Line Output Channels There are eight mono line output channels.
When bypassed, the graph displays the current filter curve as a dotted line. When bypass is disengaged, the current filter curve is displayed as a solid line. Figure 34. Loudness Dialog Dialog box The Loudness dialog box contains the following elements: 1. Graph — Displays the compensation curve currently applied to the signal. These curves are read-only, and are not adjustable from the graph. 2.
Unmute the mix‑point from the pink noise source to the output connected to the room amplifier being calibrated. With the basic gain structure previously set up, loudness can be calibrated using an SPL meter or by ear. (Loudness can also be set using an SPL meter, then fine-tuned by ear.) To calibrate loudness, use a sound pressure level meter set to “C” weighting: 1. Set the Loudness processor to Bypass (Bypass button red). 2. Place the meter in an average (but somewhat prominent) listening location. 3.
Delay Block (DLY) The delay processor block, when inserted, provides a means to delay the audio signal to compensate for loudspeaker placement in situations where speakers delivering the same signal are much farther away than others. The delay processor block is identical to the delay processor available on the input (see Delay (DLY) on page 49). Typically the near speakers would be delayed so that audio delivery time matches the speakers further away.
Volume Control (VOL) Each output channel volume block provides a mono long‑throw fader and a volume setting readout (in dB) below the fader. Volume level is adjustable with the slider or by entering the desired level directly into the volume setting readout in 0.1 dB increments. Clicking the fader handle or clicking within the fader area brings focus to the fader.
Virtual Bus Returns There are eight mono virtual bus return inputs, fed by the virtual sends. Channel controls and processing blocks described in the sub-sections that follow are identical for each virtual bus return channel. The eight returns are divided into two similar paths. Channels A through D contain a feedback suppression processing block in each channel. Channels E through H are identical except there are no feedback processing blocks.
The FBS dialog box provides the following global buttons: • Clear All — Clears all dynamic filter settings. • Lock — Locks the dynamic filters to current settings, preventing automatic updates. This temporary mode is useful while testing the system, or during the time when dynamic filters are being converted to fixed filters. When the FBS dialog box is closed, lock mode is automatically disengaged. • Bypass FBS — Turns off feedback detection when engaged (button is red).
FBS Settings Tab The Settings tab enables selection of the feedback suppressor parameters. • • For Composite View show: — The graph view is set by one of three radio buttons: • Only Dynamic FBS Filters • Only Fixed FBS Filters • Dynamic & Fixed FBS Filters (default) Mode: Q — Adjusts the notch filter Q used by dynamic filters. Similar to Q on the parametric equalizers, Q changes the bandwidth of the filter. The default setting can be modified in Tools > Options. The range is from 5 to 65.
FBS Dynamic Filters Tab This dialog contains the fifteen dynamic filters, with a scroll bar to display filters hidden due to the dialog box size. Dynamic filters are cut only notch filters, providing attenuation up to 30 dB at the specified Q. The default Q is set in the Tools > Options menu, but can be changed on the settings tab prior to engaging the FBS dynamic filters. NOTE: Changing the Q setting in the options menu after dynamic filters have been generated clears all dynamic filters.
FBS Fixed Filters Tab Fixed filters are notch filters with an adjustable center frequency and Q, and up to 30 dB of cut. The fixed filters are typically set by converting dynamic filters to fixed, however adjustments to filter parameters can be manually made from the Fixed Filters tab. Fixed Filters are inactive and the filter type is set to Unused by default (see rows 4 and 5 in figure 40). Figure 40. FBS Fixed Filters Tab No filter parameters are displayed when the filter type is set to Unused.
Filter (FILT) Filter function and interface is identical to the mic/line input channel Filter block except that only three filters are provided (see Filter (FILT) on page 30). Dynamics (DYN) There is one dynamics processor block available on each virtual path. Dynamics function and interface is identical to the mic/line input channel Dynamics block, (see Dynamics (DYN) on page 44). Loudness (LOUD) There is one loudness processor available on each virtual path.
Output Mix Matrix The DSP architecture contains an output mix matrix that connects all inputs to the line outputs, a virtual send mix matrix that connects all inputs to the virtual outputs, and an expansion (EXP) output mix matrix that connects the mic/line inputs and virtual bus returns to the expansion outputs (see figure 41 on the next page). The output mix matrix sets mix levels from the post processing inputs and post processing virtual returns, to each line output bus.

Mix‑point Behavior: Mix-point color — There are three colors of mix-points: Teal indicates standard processing (default). Orange indicates that the signal chain includes an auto‑mix processor. Green indicates that all signal processing has been bypassed, post input gain control. No mix information — A faint transparent circle (teal, green, or orange) on the mix‑point indicates that it is muted (contains no mix information).
Click a mix‑point to bring focus to that mix‑point. A circle appears around the teal mix‑point, which remains transparent. Double-click a mix‑point to open a configuration dialog box with the following components: • Mono Fader — Sets the signal level from the selected input to the output bus. Gain range is -35 dB to +25 dB.
Mix-point Examples In order to better understand how mix‑points work, the following diagrams provide examples of mixes. NOTE: To simplify the diagrams not all input and output lines are shown. Figure 42. Input 1 to Output 1 In the first example (see figure 42) input audio from Input 1 is processed and arrives at the output 1 matrix mix‑point. Double-click the mix‑point to open the dialog box.
Figure 43. All Inputs to Output 1 In the next example (see figure 43), input audio from all twelve mic/line inputs are processed individually and arrive at their output 1 mix‑points. As each mix‑point mute button is released, its output 1 mix‑point junction turns teal, and the signals are all routed to Output 1. Since all the signals are now on output signal line 1, open the individual mix‑points to adjust signal levels for the desired balance.
Figure 44. Input 1 to All Outputs In the example in figure 44, input 1 has been routed to all eight outputs by unmuting the mix‑point for Input 1 for each output (1 through 8) bus. The example also shows the mix‑point for output four with input processing bypassed (green) and the mix-point for output eight with active automix.
Virtual Send Bus Mix Matrix The DSP architecture contains a Virtual Send Bus mix matrix that connects the inputs and virtual bus return signals to the virtual sends. There is an additional mix matrix to route EXP input signals to the virtual sends. The DSP Configurator main screen provides control of the virtual bus mix matrix, used to set levels from input signals to the virtual sends.
In the example in figure 46 below, input 1 is sent to the virtual send bus by muting all eight signals on the Input 1 output mix‑points and unmuting virtual send bus output 1. The virtual bus now serves as additional signal processing for the input. The signal routes from virtual send A through the virtual bus A signal chain before it is sent to the virtual bus return mix‑point and finally to output 1. This configuration is useful when more than one input requires identical processing.
Expansion Outputs Mix Matrix The DSP architecture contains a third mix matrix that supports connection and control of a second DMP 128 using the included shielded CAT 6 cable. The output connects the mic/line inputs and virtual returns to the Expansion Outputs. The DSP Configurator main screen provides all necessary control of the mix matrix. Expansion Outputs Mix Matrix Inputs to EXP Sends (1-8) Virtual Returns to EXP Sends (9-16 only) Exp Inputs to Outputs EXP Inputs to Virtual Sends Figure 47.
Extron EXP Bus Using the Extron Expansion port (EXP), two DMP 128 units can be connected together for bi-directional communication of 16 channels of audio. The expansion bus mix matrix can route any or all of the mic/line inputs to any or all of the expansion outs (1 through 8). In addtion, there are eight channels (expansion outs 9 through 16) directly connected to the virtual bus returns. Connecting the EXP Ports Minimal setup is required for EXP port communications.
4. Connect the EXP port of one unit to the EXP port of a second unit using the included shielded (or similar) CAT 6 cable. 100-240 ~ 0.6A MIC/LINE INPUTS MIC +48 V 1 5 50/60 HZ 100-240 ~ 0.
The mic/line inputs and the virtual bus returns make up the expansion bus mix matrix that feed EXP outputs 1 through 8 (see figure 49, Ä) of the primary unit. They are connected to EXP inputs 1 through 8 of the secondary unit (see figure 49, Å), respectively. The primary unit EXP outputs 9–16 (see figure 49, Ç) are direct feeds from virtual bus returns A – H (post processing).
Group Masters There are 32 Group Masters that can each be configured to simultaneously control up to 16 group members. Group masters are configured in DSP Configurator and saved in the device. Working in emulate mode, group masters are saved in a configuration file and pushed to the device upon connection. A group master can either be a gain control or a mute control. Only one control type can be selected as group members for control by a group master.

Optimizing Audio Levels The DMP 128 uses floating point DSP technology, processing data using a combination of 32- and 128-bit algorithms. The analog to digital converters (ADC) and digital to analog converters (DAC) sample at 48kHz, with 24-bit resolution. With floating point DSP it is extremely difficult to clip the audio signal within the DSP audio signal chain, after the ADC input and before the DAC output. That means the audio signal must not be clipped at the input ADC.
The remainder of this section references the gain, trim and volume controls outlined in figure 63. a b c d e Figure 63. Gain, Trim and Volume Controls a b Mic/Line input gain Pre-mixer gain c d Mix‑point gain e Output volume Post-mixer trim About Setting Gain Structure There are two approaches the system designer can take in setting up gain structure depending upon where output volume is controlled.
Setting Input Gain Floating point DSP technology is internally more flexible than fixed point. However, the input ADCs and output DACs always run as fixed point, so it is important to optimize the audio by setting the input level as close to 0 dBFS as possible. This maintains the resolution at 24-bit. Within the DSP it is not critical to maintain audio levels at 0 dBFS in order to secure the resolution at 24-bit. Input gain is set using the intended input source device and typical source material.
Adjusting Pre-mixer Gain After setting input gain, add desired processors into the input signal chain. The pre‑mixer gain control (see figure 63, b on page 101) is used to compensate for level changes due to processing. Adding a compressor generally reduces the signal level, while a filter can boost or cut the overall signal level. When changes are made to filter settings after setting dynamics processors, re‑check the levels in the dynamics processors to make certain they are still valid.
Setting Mic/Line Input and Mix Levels In this example, the mic/line input 1 signal is sent to output 1. To set the mic/line input and mix levels: 1. Connect a microphone to Input #1. 2. Double-click the mix‑point (see figure 63, c on page 101) for mic/line input 1 to output 1 to open the dialog box for that mix‑point, and unmute the mix‑point to place that signal into the mix. The default level for the mix‑point is 0 dB, or unity gain. 3.
Signal Path Building Blocks The discrete signal paths (mic/line input, virtual return input, and line output) can be individually loaded with pre-configured, modular templates called building blocks. These blocks are designed for specific microphones, source devices or speaker destinations and can greatly streamline initial configuration. The blocks are configurable and are more versatile than a global template.
Figure 65. Building Blocks Dialog Box The following steps select a lavalier microphone configuration for input #1. 1. Click the Input 1 box. The Building Blocks dialog box (see figure 65) opens. 2. Select Lavalier by placing the mouse over the text Lavalier. The selected text changes color and is underlined. Click the selection. 3. The input channel loads the pre-configured processor blocks, sets the gain, and names the channel Lavalier.
Adding a Building Block Custom building blocks are created using a signal path configured for a specific device. For example, when a new mic is connected to Input #3, the signal path might be tailored specifically for that mic. In this example a gain setting is applied and a noise gate inserted. They are then stored as a custom building block. To create a building block for the new microphone: 1. Click inside the input number box (see above). 2.
6. The new mic configuration is now a building block used to quickly configure new devices. A new configuration can also overwrite existing templates. To Overwrite an Existing Configuration: 1. Click in the input number box. 2. In the dialog box that opens, select the Add Block icon in the upper left. 3. In the Add a Building Block dialog box, type an existing name for the new device. 4. Select a folder for the new device (see above). 5. Click Add.
6. A dialog box prompts to warn an existing configuration will be overwritten. Click Yes. 7. The new mic configuration overwrites the existing template and is ready to use. Organize Building Blocks The Tools menu contains a utility that allow building blocks organization and rearrangment to suit an application. Individual blocks and folders are moved or deleted and new folders created.
Delete a Building Block Delete a building block to remove it from the list. If you delete a default building block, you can restore it if needed (see Restore Default Building Blocks below). To delete a building block: 1. From the main menu, select Tools>Organize Building Blocks. The Organize Building Blocks dialog box opens. 2. To delete a folder and the associated building blocks, select the folder from the list and click the icon as shown on the right. 3.
To import a building blocks file: 1. From the menu, select Tools>Organize Building Blocks. The Organize Building Blocks dialog box opens. 2. Click the Import Building Blocks File icon. The “Import from...” dialog box opens. 3. Browse to and select the desired building blocks file. 4. Click Open. The selected building blocks file is imported into the Organize Building Blocks dialog box.
Dante Installation and Operation (AT Models Only) This section describes the DMP 128 AT network installation, configuration, and control using Dante Controller for Windows and includes: • DMP 128 AT Bus • Dante Controller Software Installation • Creating a Physical Dante Network • Dante Controller Configuration • Selecting Inputs and Outputs for Dante • Signal Routing with Dante • Using the Extron Expansion Bus with DMP 128 AT Devices DMP 128 AT Bus DMP 128 devices equipped with an AT bus use
Dante Controller Software Installation The DMP 128P AT uses Dante Controller for Windows from Audinate to select and route inputs and outputs for all connected DMP 128 ATs and other Dante-compatible audio devices. Download and install the latest version of Dante Controller for Windows from the included software DVD or from the Dante Controller product page at www.extron.com .
4. In the Unit Name: field, enter a descriptive name for the DMP 128 (typically the device name and location) to enable easy identification on the network (see figure 68). DMP128-ConfRoom1 Unit name can be up to 24 characters drawn from the alphabet (A-Z), digits (0-9), and minus sign/hyphen (-). No spaces are permitted and it is not case sensitive. The first character must be an alpha character. The last character must not be a minus sign/hyphen. Figure 68. Device Settings - Unit Name 5.
Dante Device Discovery The Tools menu also provides a way to locate other Dante devices on your network. Once the device is named (see Dante Network Audio Setup on page 113), it can easily be identified as a Dante host from any other Dante device. To locate Dante devices on an audio network: 1. Select Tools>Device Settings. The Device Settings dialog opens. 2. Select the Dante Device tab. 3. Dante devices are found by either: a. Entering the name in the AT name: field, -orb.
Creating a Physical Dante Network Basic Configuration A physical network is required to share Dante audio channels between DMP 128 AT devices. Each DMP 128 AT contains a 4-port Gigabit switch with four RJ‑45 connectors located on the back panel to accept standard network cables.
Redundant Configuration Redundant network configurations can be employed, however, you must observe the proper order of rear panel AT port connections. In redundant mode the 4‑port switch acts as two separate 2-port switches that duplicate audio traffic (see figure 71). The two sets of switches (primary and secondary) cannot be connected together anywhere in the system.
Dante Controller Configuration Now that the DMP 128 ATs are configured for network operation and the Dante software is installed, Dante Controller must be configured. Start Dante Controller To launch Dante Controller. From the DSP Configurator menu bar, select Tools>Network Audio Control. Figure 72. Network Audio Control Dante Controller launches. If the network has a DHCP server, it receives its IP configuration using the standard DHCP protocol.
When the network scan is compete, Dante Controller opens in Network View. Dante Transmitters Dante Receivers Connection Points Figure 73. Dante Network View Receivers, representing Dante device inputs, are on the left side running vertically. Transmitters, representing Dante device outputs, are along the top running horizontally. The connection points form a large matrix in the center of the screen.
Rename a Dante Device 3 2 4 Figure 74. Dante Controller - Rename Device To rename a connected device: 1. From the toolbar, select Device > Device View or use . 2. From the Device View dialog box, select Device Config. 3. From the pulldown list, select the device to rename. 4. In the Rename Device field, type the new name for the device following the naming conventions note on the previous page. 5. Repeat steps 2 to 5 for each connected device. 6.
Rename an Input or Output To simplify setup and operation of large matrix systems, rename the input (receiver) and output (transmitter) lines to a label indicating the input a source device is connected to or the output a receiver is connected to. 2 3 4 Figure 75. Dante Controller - Rename Inputs and Outputs To rename an input: 1. From the menu, select Device > Device View or use . 2. From the drop-down list in the upper center of the screen, select the device. 3.
Selecting Inputs and Outputs for Dante Dante Controller is used for all network level signal routing, however DSP Configurator assigns the input and output channels to the AT bus. The line outputs, expansion outputs, and virtual returns are available on the AT bus outputs.
The DMP 128 output lines are always the first eight transmitter lines (Outputs 01 through 08 in figure 77, d). The eight expansion outputs (see figure 76, b on the previous page) appear in the Dante transmitter list (item d, below), as EXP_Out-01 to EXP_Out-08). The eight virtual sends of the DMP 128 (figure 76, c) appear as EXP_ Out-09 through EXP_Out-16. Dante Transmitters 4 Figure 77.
Signal Routing with Dante Channels either transmitted to the network, or received from the network are routed using the main Dante network view (see figure 79). Figure 79. Dante Routing View There are several icons used to communicate the status of both the transmitter and receiver channels and the connections made.
Using the Extron Expansion Bus with DMP 128 AT Devices A DMP 128P AT model can be connected to a non-AT model by the Expansion (EXP) ports with the following exceptions: • Two AT models cannot be connected together using their EXP ports. • AT models are always the primary unit. The non-AT model must be set as the secondary unit. • The sixteen EXP outputs from the non-AT secondary unit connect to the AT primary unit at inputs 41 through 56.
Telephone Interface This section describes the telephone interface and control, including: • Telephone Configuration • Telephone Dialer • Third Party Control of the Phone Dialer The DMP 128 provides a telephone interface with separate input and output signal processing paths. The telephone input (Rx) is identical to the other input processing paths except the AEC block is not available (see Telephone Rx (DMP 128 C P and DMP 128 C P AT only) on page 58).
Telephone Dialer A telephone dialer is provided to aid setup and troubleshooting. To use the telephone dialer: From the main DSP Configurator screen toolbar, select Tools>Phone Dialer (see figure 80). The phone dialer dialog box opens (see figure 81, below). The phone dialer uses the connected telephone lines and provides the same features as a normal dialing interface to assist the installer with setup and testing. Figure 80.
Third Party Control of the Phone Dialer See the SIS section for commands to control and query the phone dialer (see Telephone commands on page 146). When sending a dial command or off hook command using SIS commands, you must first initialize the phone. To prevent excessive levels from the dial tone, or on hook and off hook sounds, fine control of the phone receive audio is recommended during dialing. Examples of recommended phone control sequences follow: Off hook: 1. Send receive mute SIS command to DMP.
SIS Programming and Control This section describes SIS programming and control of the DMP 128, including: • Connection Options • Host-to-device Communications • Command and Response Tables Connection Options The DMP 128 Digital Matrix Processor can be remotely connected via a host computer or other device (such as a control system) attached to the rear panel RS‑232 port or LAN port, or the front panel USB Config port.
RS-232 Port The DMP 128 has a serial port that can be connected to a host device such as a computer running the HyperTerminal utility, or the DataViewer utility. The port makes serial control of the switcher possible. Use the protocol information listed above to make the connection (see Host-to-device Communications on page 132).
To Establish a Network Connection to the DMP 128: 1. Open a TCP socket to port 23 using the mixer IP address. NOTE: If the local system administrators have not changed the value, the factory‑specified default, 192.168.254.254, is the correct value for this field. 2. The DMP 128 responds with a copyright message including the date, the name of the product, firmware version, part number, and the current date/time. a.
Host-to-device Communications The commands listed in the following tables perform the same functions, but are encoded differently to accommodate the requirements of each port (Telnet or browser). DMP 128-initiated Messages The DMP 128 initiates messages under specific conditions. No response is required from the host. The DMP 128-initiated messages are listed here (underlined).
When programming, certain characters are more conveniently represented by their hexadecimal rather than ASCII values. The table below shows the hexadecimal equivalent of each ASCII character: ASCII to HEX Conversion Table Space • I l Figure 83.
Simple Control Port Commands - Telnet and Web-browser Accessible Upper and lower case text can be used interchangeably except where noted. Port 23 is default for Telnet. Port 80 is default for web browsers. They both can be mapped to different ports. There are minor differences when implementing these commands via Telnet or via URL encoding using a web browser.

DSP SIS Commands Many digital signal processor (DSP) functions; gain, mute, group masters, and a protected configuration can be controlled using SIS commands. These commands follow the same general rules as basic SIS commands, but the variables (X/) tend to be more complex. Also, an understanding of the audio signal flow is helpful to understanding the commands. Figure 84 shows the specific DSP functions available for SIS commands.

DSP SIS Commands for Mix-point Level and Mute Control Many functions; gain, mute, group masters, mix-points, and a protected configuration can be controlled using SIS commands. These commands follow the same general rules as basic SIS commands, but the variables (X/) tend to be more complex. Before attempting SIS control of the DSP, a comprehensive understanding of the audio signal flow is helpful to understanding the commands.
Selecting Mix-points Mix-points are controlled by their address. Each mix-point in figure 94 has an individual address selected and controlled using SIS commands. (A mix-point contains a level control and a routing control that mutes or unmutes the signal path from the input mix‑point to the output.
Setting Audio Levels The mix-point level is controlled using SIS commands. The commands template follows a similar structure as mute and unmute commands. The audio conversion tables are the same for all mix-points (see table 2 beginning on page 149). Although a greater range is shown in the table, the minimum and maximum levels are the same for all mix-points (–35.0 to +25.0 dB). To select the mix-point, use the table 3 beginning on page 175 to find the specific mix‑point.
SIS Command and Response Table for DSP Mix-point and Level Control Setting the level of a mix-point requires the mix-point address and level value. Making a connection between a mix-point input and output requires the mix-point be unmuted.
SIS Command Mix-points The mix-points are divided into three main matrix mixers: the Main or Output mix matrix (a), the virtual send bus mix matrix (b), and the expansion (EXP) outputs mix matrix (c).
Output Mixer The output mixer routes the mic/line inputs (a), virtual returns (b), and expansion bus inputs (c), to the outputs.
