1 Chapter One Introduction About this Manual About the Media Presentation Matrix Switcher Definitions Features PRELIMINARY MPX Plus 866 A
Introduction About this Manual This manual contains installation, configuration, and operating information for the Extron MPX Plus 866 A Media Presentation Matrix Switcher. In this manual, the MPX Plus 866 A may be referred to as “the MPX” or “the switcher”. About the Media Presentation Matrix Switcher A media presentation switcher combines multiple A/V switchers, of different video formats, in one box.
The MPX Plus 866 A has the following switching and mixing capabilities: • An 8-input by 6-output VGA matrix switcher, comprising the computer video group • A 6-input by 6-ouput S-video and composite video matrix switcher, comprising the low resolution video group • A 14-input by 6-output primary audio matrix switcher, comprising the program audio group • Four mono microphone (mic)/line level inputs that can be mixed with one or all audio outputs of the primary audio group N Video ties can only be made withi
Introduction, cont’d The MPX can be operated by any of the following connected to either RS-232 port or the LAN port: • A control system • A PC and any of the following: The Extron SIS The Extron Windows-based DSP Configurator program The Extron Windows®-based Matrix Switchers Control Program • An Extron MKP 2000 remote control panel • An Extron MKP 3000 remote control panel (RS-232 only) An Extron MCP 1000 remote control panel and/or MKP 1000 remote keypad The switcher is housed in a rac
Features Video features Computer video group — The switcher inputs and outputs RGBHV (VGA), RGBS, RGsB, RsGsBs, or Y, R-Y, B-Y video on 15-pin HD connectors. Low resolution video group — The switcher inputs and outputs NTSC 3.58, NTSC 4.43, PAL, or SECAM S-video and/or composite video.
Introduction, cont’d Digital Sync Validation Processing (DSVP™) (computer video group) — In critical environments or unmanned, remote locations, it may be vital to know that sources are active and switching. Extron’s DSVP confirms that input sources are active by scanning all sync inputs for active signals. DSVP provides instantaneous frequency feedback for composite sync or separate horizontal and vertical sync signals via the switcher’s RS-232 ports or Ethernet port.
Audio features Primary audio group — Input and output balanced or unbalanced stereo audio on 3.5 mm, 5-pole captive screw terminals. • Audio input gain/attenuation (primary audio group) — Individual input audio levels can be adjusted so there are no noticeable volume differences between sources. Users can set the input level of audio gain or attenuation (-18 dB to +24 dB) via the Ethernet port, any RS-232 port, or the front panel.
Introduction, cont’d General features Switching flexibility — Provides individually buffered, independent matrix switched outputs with audio follow and audio breakaway. N Program audio inputs are independent of the video groups, but must be tied to the computer/audio group (outputs 1 through 6). • Tie any input to any or all outputs within a video group • Quick multiple tie — Multiple inputs can be switched to multiple outputs within a video group simultaneously.
Rack mounting — Rack mountable in any conventional 19" wide rack. Three front panel security lockout modes (Executive modes) — If a matrix switcher is installed in an open area, where operation by unauthorized personnel may be a problem, either of two security lockout modes can be implemented (the third mode is unlocked). When a front panel locked mode is enabled, a special button combination or SIS command is required to unlock the front panel controller and make the front panel fully operational.

The switcher reverts to that factory firmware the next time power is cycled off and on unless a firmware update is performed before the power cycle. 1.
Operation, cont’d Troubleshooting This section gives recommendations on what to do if you have problems operating the switcher. Ensure that all devices are plugged in and powered on. The switcher is receiving power if any of the front panel button indicators are lit. 2. Check to see if one or more outputs are muted. 3. Ensure an active input is selected for output on the switcher. 4. Ensure that the proper signal format is supplied. 5. Check the cabling and make corrections as necessary. 6.
Configuration Worksheets Rather than trying to remember the configuration for each preset, use worksheets to record this information. Make copies of the blank worksheet on page 3-54 and use one for each preset configuration. Cross out all unused or inactive inputs and outputs. Use different colors for video and audio and for computer video and low resolution video. Worksheet example 1: System equipment Figure 3-7 shows a worksheet in a fictional organization with the system hardware annotated.
Operation, cont’d Worksheet example 2: Daily configuration Figure 3-8 continues from worksheet example 1 by showing the video and audio ties that make up the configuration of preset 1. A black line shows video ties and a red line shows the audio ties.
Worksheet example 3: Test configuration The A/V system in our fictional organization needs to be fine tuned on a regular basis. Figure 3-9 shows a typical test configuration, with an Extron video test generator (inputs 8 and 13) connected to each video group. Each VTG generates a test pattern of the appropriate resolution to all connected outputs.

SIS™ Programming and Control RS-232 Ports The switcher has three serial ports that can be connected to a host device such as a computer running the HyperTerminal utility, an RS-232 capable PDA, or a control system. These ports make serial control of the switcher possible. The serial ports are: • two (Primary and Secondary) rear panel RS-232 ports on 3-pin captive screw connectors • the front panel Configuration (RS-232) port, a 2.

SIS™ Programming and Control, cont’d Ethernet (LAN) Port The rear panel LAN connector on the switcher can be connected to an Ethernet LAN or WAN, making makes SIS control of the switcher possible. Communication between the switcher and the controlling device is via Telnet (a TCP socket using port 23). The Telnet port can be changed, if necessary, via SIS.
Establishing a connection Establish a network connection to an MPX switcher as follows: 1. Open a TCP socket to port 23 using the switcher’s IP address. N If the local system administrators have not changed the value, the factoryspecified default, 192.168.254.254, is the correct value for this field. The switcher responds with a copyright message including the date, the name of the product, firmware version, part number, and the current date/time.
SIS™ Programming and Control, cont’d Host-to-Switcher Instructions The switcher accepts SIS commands through the RS-232 ports and Ethernet port. SIS commands consist of one or more characters per command field. They do not require any special characters to begin or end the command character sequence. Each switcher response to an SIS command ends with a carriage return and a line feed (CR/LF = ]), which signals the end of the response character string. A string is one or more characters.
Typnn•x] The switcher initiates the Typ message when the video format for a video input is changed from the front panel. “nn” is the input number, • is a space, and “x” is the format: 1 = composite video, 0 = S-video. Vmtnn•x] The switcher initiates the Vmt message when a video output mute is toggled on or off from the front panel. “nn” is the output number, • is a space, and “x” is the mute status: 1 = on, 0 = off.

Switcher Software Control Software The Windows®-based Extron Digital Signal Processor (DSP) Configurator program and Matrix Switchers Control Program communicate with the switcher via the Ethernet LAN port, either rear panel RS-232 port, and the front panel Configuration (RS-232) port to provide an easy way to set up ties and sets of ties. The DSP Configurator further provides a tool for configuring and controlling all of the advanced MPX Plus DSP audio mixing and other processing functions.
4. Follow the on-screen instructions.
Switcher Software, cont’d DSP Configurator Program Starting the program N Extron recommends connection via the Ethernet LAN port for the DSP Configurator program. To run the DSP Configurator Program, click Start > Programs > Extron Electronics > DSP Configurator > DSP Configurator. The DSP Configurator program starts in Emulate mode (figure 5-3, on the next page).
3 4 5 6 PRELIMINARY 1 2 7 Figure 5-3 — DSP Configurator program window The DSP Configurator program window consists of a number of signal processor chains, an A/V matrix block, and a mic mixer block. a Program audio input (computer/audio group and video/audio group) signal processor chains b c d e f g Mic/line input signal processor chain A/V matrix block Output signal processor chain (pre mic mixer) Mic mixer block Output signal processor chain (post mic mixer) DSP usage meter.
Switcher Software, cont’d Audio signal processor chains and control blocks Each of the four signal processing chains (a, b, d, and f) consists of a series of control blocks of two basic types that are specific to that chain: gain, trim, post-gain, and volume control blocks (collectively known as “gain blocks” – ) and processor blocks ( ). For example, the computer audio input 1 chain consists of a gain fader, a filter block, two dynamic blocks, a delay block, and a trim fader.
PRELIMINARY Each processor has a set of associated parameters that define that processor (such as a frequency curve); those parameters can be accessed and changed by doubleclicking again on the now inserted process block. This action opens a customizable dialog box, a new window that contains parameters for the process (figure 5-6). Figure 5-6 — Sample processor dialog box • The Set Defaults button lets you discard all custom settings and reload the factory defaults.
Switcher Software, cont’d Program audio input signal controls (a) The program audio input signal processor chain makes adjustments to program audio material before it is tied to specific outputs. Gain control — The always-present gain control provides the same basic audio input level adjustments that are available from the front panel (see “Viewing and adjusting the input audio level“, in chapter 3, “Operation”).
Bass and treble filters — Also known as shelving or tone filters, the separate bass and treble filters give the ability to cut or boost gain evenly above or below a given frequency, with the end-band shape giving the visual appearance of a shelf. These filters are typically applied to program material, and are expressed as bass and treble control. The bass default frequency is 100 Hz and the treble default is 8 kHz.
Switcher Software, cont’d • Noise gate — The noise gate is an expander, expanding the dynamic range of a signal below a specified threshold. To simplify, it makes soft signals softer, effectively removing background noise while allowing a stronger signal, above the threshold, to pass. Using a high ratio of 20:1, the expander closes the audio path below the threshold, eliminating background noise, opening the path above the threshold to allow signal to pass; hence the term noise gate.
Feedback suppressor block — The feedback suppressor processor block, when inserted, detects feedback on a live microphone channel, and uses a set of fixed and dynamic filters to counteract the frequency peaks at the detected feedback frequencies. You may possibly achieve an additional 3 dB to 9 dB of mic gain where feedback would have otherwise prevented these levels. Dynamics blocks (2) — The two dynamics processor blocks, when inserted, each provide one of four dynamic processors.
Switcher Software, cont’d Output signal, pre mic mixer, controls (d) The output signal processor chain, pre mic mixer, makes adjustments to program audio material, after it is tied to a specific output but before it is mixed with microphone audio.
Output signal, post mic mixer, controls (f) The output signal processor chain, post mic mixer, makes adjustments to mixed program and microphone audio, before it is output to the selected speakers or other audio devices. Filter block — The filter processor block, when first inserted, provides one of four filter selections; additional filters can be then be added.
Switcher Software, cont’d A/V matrix block (c) PRELIMINARY The A/V matrix block (figure 5-7) displays the current tie configuration of either the program’s own emulation or the connected matrix switcher and provides a way to make or break ties. Figure 5-7 — A/V matrix block • To create a tie, drag a line from an input node ( ) to one or more output nodes or right-click an input node and select Connect To All Outputs.
Mic mixer block (e) The mic mixer block (figure 5-8), an array of points where mic audio can be mixed into the output audio, provides a way to unmute and mute the normally muted inputs from the mic/line input signal processor chain. Unmuting effectively mixes the mic inputs into the audio outputs at the level set in the left and right mix controls.
Switcher Software, cont’d Group masters Any of the gain blocks’ gain, volume, and trim fader controls can be grouped with other gain blocks of the same type (in the same location in the audio signal path but for different inputs or outputs) for single-fader control of the entire group (figure 5-9). Mute controls within the blocks can also be grouped (figure 5-10). Up to 32 groups can be created, each can include up to 16 group members.
Soft limits ( ) are adjustable, letting you set the ceiling and floor for the group. Grouped faders move together at relative levels to the top or bottom of their travel. If one fader reaches the limit of its travel first, it retains that position while the other faders continue to travel. When the grouped faders travel in the reverse direction, the fader that was at its limit reverts to its position relative to the other faders.
Switcher Software, cont’d Deleting a group master Delete a group as follows: 1. Click Tools > Configure Groups to open the Configure Groups dialog box. N Or, click View > Group Controls and then click the Add a Group menu selection. 2. In the Select Group drop-down box, click a numbered group (such as “Group #1“) to select it (figure 5-11). 3. Click Delete Current Group. 4. Click Yes in the Confirm Deletion dialog box.
• Click Tools > Increment/Decrement Simulator to open a dialog box (figure 5-13) that lets you experiment with fine adjustments. N • You must select a group before the other controls in the dialog box are active. The size of the increment can be changed from its default value of 1 dB by typing a value in the Increment Value or Decrement Value field, to as fine as 0.1 dB. Click Tools > Group Details Report to create a Microsoft Word file that details all created groups (figure 5-14).
Switcher Software, cont’d Video-only I/O page controls Three video control blocks are available only on the video-only I/O page (figure 5-15), selected by clicking Video Only in the legend field, clicking View > Video I/O, or pressing the keyboard F4 key. 9 PRELIMINARY 8 7 Figure 5-15 — DSP Configurator program window, video-only I/O page 5-20 g S-video/composite video selection block — Low resolution video inputs 11 through 14 are individually configurable as either S-video or composite video.

Design rule verification You can inadvertently recall a combination of partial presets that causes an overload. The user-selected design rule verification function analyzes and compares all presets. Execute the design rule verification function by clicking Tools > Design Rule Verification. After verification, if no combination of presets that would cause an overload is detected, the function prepares an on-screen report stating “The current configuration has been successfully verified“.
Switcher Software, cont’d Keyboard navigation The DSP Configurator program is fully navigable using the computer keyboard. Some keyboard navigation behavior matches Windows standards, while other behaviors are specific to the DSP Configurator program. When the program is started, the cursor focus is in the upper left corner of the program audio input (computer/audio group and video/audio group signal processor chains (a on figure 5-20). The Input 1 Gain block is green highlighted [ ]).
Standard Windows navigation The keyboard keys navigate and function as follows: Tab key — Sequentially jump among major segments of the DSP Configurator program.
Switcher Software, cont’d DSP Configurator-unique navigation Making ties Video and audio ties can be made from the keyboard as follows: 1. Arrow ( , , , and ) and/or Tab ( ) to the A/V matrix block (b) input node ( ) from which you will make the tie. The node is marked by a green outline ( ). 2. Press and hold the Shift key while you press the right arrow to drag the potential tie (dashed line) to the corresponding output node (input 1 to output 1, 2 to 2, and so on).

Shift-Page Up/Page Down arrow upper limit in 10 dB increments. Shift-Home Shift-End Shift Home Shift End or Shift — Moves the soft upper limit in Shift Shift Page Up or Shift Page Down — Moves the soft — Moves the soft upper limit to the upper default. — Moves the soft upper limit to the fader’s position.
Setting the input and output gain structure Before calibrating loudness, set up the system gain structure. 1. Set the signal generator to output -10 dBFS or use recorded program material at -20 dBFS. 2. Set the input gain in the DSP Configurator so that the input meter reads -20 dBFS. 3. For program material, set the input level to approximately -15 dBFS, with peaks at no more than -5 dBFS to -3 dBFS.
Switcher Software, cont’d Finalizing the output gain structure Adding a compressor generally reduces the signal level, while a filter may boost or cut the overall signal level. Loudness boosts the overall signal level, but mostly at lower volume settings (see “Calibrating loudness” for more information). 1. Add any processors that you wish to use into the output signal chain. After adding processors to the output signal chain, the output volume level may clip when set to or near 100%. 2.
Adjusting the post-matrix trim Adjusting the post-matrix trim is a bit of a balancing act. This section provides guidelines, but it may take a bit of going back and forth to set levels just right. For example, the output level can be controlled and kept below clipping using a compressor or limiter in the output dynamics block. However, adjusting the postmatrix trim affects how the compressor or limiter works. 1. Open the output volume dialog box and the post-matrix trim dialog box. 2.
Switcher Software, cont’d 6. In the loudness dialog box, adjust the fader until the value in the “SPL” readout box matches the reading on the SPL meter. N Calibration can be performed with the output channel volume set to any comfortable listening level, but a relatively loud volume that can be easily measured is preferred. Loudness is now calibrated. 7. Release the loudness processor’s bypass to hear the compensation.
Matrix Switchers Control Program Starting the program Many items found in the Matrix Switchers Control Program (the WCP) are also accessible via optional front panel controls (see chapter 3, “Operation”) and under SIS control (see chapter 4, “SIS Programming and Control”).

A Appendix A Ethernet Connection Ethernet Link Subnetting — A Primer PRELIMINARY MPX Plus 866 A
Ethernet Connection LINK ACT The rear panel Ethernet connector on the switcher can be connected to an Ethernet LAN or WAN. This connection makes SIS control of the switcher possible using a computer connected to the same LAN. ETHERNET Ethernet Link Ethernet connection The Ethernet cable can be terminated as a straight-through cable or a crossover cable and must be properly terminated for your application (figure A-1).
Pinging to determine Extron IP address The ping utility is available at the DOS prompt. Ping tests the Ethernet interface between the computer and the switcher. Ping can also be used to determine the actual numeric IP address from an alias and to determine the web address. Ping the switcher as follows: 1. On the Windows task bar, click Start > Run. 2. At the Open prompt, type command. 3. Click the OK button. 4. At the DOS prompt, type ping {IP address} and then press [Enter].
Ethernet Connection, cont’d Connecting as a Telnet client The Microsoft Telnet utility is available from the command prompt. Telnet lets you input SIS commands to the switcher from the PC via the Ethernet link and the LAN. Access the command prompt and start Telnet as follows: 1. On the Windows task bar, click on Start > Run. 2. At the Open prompt, type command. 3. Click the OK button. 4. At the prompt, type telnet and then press [Enter]. The computer returns a display similar to figure A-3.
Escape character and Esc key When Telnet is first started, the utility advises that the Escape character is ‘Ctrl+]’. Many SIS commands include the keyboard E key. Consequently, some confusion may exist between the Escape character and the Escape key. The Telnet escape character is a key combination, the Ctrl key and the ] key pressed simultaneously, that returns you to the Telnet prompt while leaving the connection to the switcher intact. The Escape key is the E key on the computer keyboard.
Ethernet Connection, cont’d Subnetting — A Primer It is not the purpose of this manual to describe TCP/IP protocol in detail. However, some understanding of TCP/IP subnetting (a subnet is a subset of a network — a set of IP devices that have portions of their IP addresses in common) is necessary in order to understand the interaction of the switcher and the mail server gateway.
Determining whether devices are on the same subnet To determine the subnet, the local device’s IP address is compared to the remote device’s IP address (figure A-6). Each address’s octets are compared or not compared, depending on the value in the related subnet mask octet. • If a subnet mask octet contains the value 255, the related octets of the local device’s address and the remote device’s IP address are unmasked. Unmasked octets are compared (indicated by ? in figure A-6).

DSP SIS commands Command/Response Table for DSP SIS Commands Many digital signal processor (DSP) functions; gain (which includes the mic mixes), mutes, 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/s) tend to be more complex. Also, a comprehensive understanding of the DSP’s audio signal flow is helpful to understanding these commands.
