32 System Configuration ~ Inputs and Outputs Inputs and Outputs ✍ Inputs 1–4 accept either microphone (-55, -25dB) or line level (0dB) inputs. Inputs 1–4 To open the Inputs 1–4 configuration window, click the Inputs 1–4 button on the Flow Screen. The In 1–4 button on the Matrix Screen will also open this window. These inputs are balanced and support both mic and line levels. ✍ ClearOne recommends using the XAP to mute mics instead of using the mute provided by some microphones.
33 System Configuration ~ Inputs and Outputs The Speech Leveler is a compander that is optimized for speech audio. It quickly equalizes the difference in speech levels in the room without bringing up noise. If you use AGC with the Speech Leveler, set the AGC Response Time to >2 seconds. AGC adjusts softer and louder input audio to a consistent level that you select (the target level). The target level range is from -30 to 20dB in 1dB steps. The default target level is 0dB.
34 System Configuration ~ Inputs and Outputs If you select a virtual echo cancellation reference, the Virtual Reference window will open. You can also open this window from the G-Ware toolbar. Figure 3.30. Virtual Reference toolbar button Figure 3.31. Virtual Reference window. Use this window to select which signals will be used by the four Virtual Reference points. The routing matrix portion of this window can not be edited. Virtual references are used when you need to reference multiple outputs.
35 System Configuration ~ Inputs and Outputs Non-linear Processing (NLP) The Non-linear Processing (NLP) feature increases the power of echo cancellation for difficult acoustical environments. NLP features four settings: Soft (6dB), Medium (12dB), Aggressive (18dB), and Off. Use NLP with care; corresponding trade-offs can include suppression and half-duplex operation. Default is Soft.
36 System configuration ~ Inputs and Outputs Figure 3.33. Inputs 1-4 Filters window Type Use the Type list to select from the following input filters: All Pass, High Pass, Low Pass, Notch, and PEQ. G-Ware features other filters which are configured in the Processing section of the software (see page 49). • All Pass. Frequency range is 20Hz to 20kHz with resolution to 1Hz or four places (whichever is larger). • High Pass. Selectable frequency cutoff is 20Hz to 20kHz, in 1Hz increments.
System Configuration ~ Inputs and Outputs Bandwidth. Bandwidth establishes the difference between the upper and lower points of a filter’s audio passband. Bypass. The Bypass box, when selected, bypasses the selected filter. Phase. Phase generates—on the graph—the phase relationship of the graphed frequency response. Bypass All. Bypass All bypasses all filters. Add Filter. Add Filter adds a filter to the graph, centered at 1kHz and 0dB. Remove Filter. Remove Filter removes the selected node from the graph.
38 System Configuration ~ Inputs and Outputs Gate The XAP 400 has unique gating parameters which control microphone activation. The Gate button on the selected input in Inputs 1–4 window opens the Gate configuration window where you can establish the gating parameters for the input. Activation There are three mic activation settings: Auto Gate, Manual On, and Manual Off. • Auto Gate determines mic gating based on the input level and gating settings for the gating group the input is assigned to.
System Configuration ~ Inputs and Outputs Figure 3.36. XAP 400 automixing gate functions Gate Ratio Gate Ratio specifies how much louder the audio level must be above the ambient level before the channel gates on. The gate ratio range is from 0 to 50dB. Default is 15dB. Hold Time Hold Time determines how long the channel stays gated on after the audio is below the threshold. The hold time range is from .1 to 8.0 seconds. Default is .3 seconds.
40 System Configuration ~ Inputs and Outputs The PA Adapt Reference and AEC Reference are the same for each channel. If you change the PA Adapt Reference for a channel, you will also make the same change to that channel’s AEC Reference. ✍ PA Adapt and AEC Reference When using either the PA Adaptive mode (see page 38) or Acoustic Echo Cancellation (see page 33), the output that carries this information, i.e. the reference output, must be defined.
41 System Configuration ~ Inputs and Outputs Gating Group Select In addition to specifying gating characteristics for each mic input, you can assign the inputs to a gating group for greater flexibility and control. When inputs are assigned to a gating group, the gating information from the inputs is used to Figure 3.40. Gating Group Select pane control how the entire mixer behaves.
42 System Configuration ~ Inputs and Outputs 3. Leave 1st Mic Priority selected (default) to enable this feature; otherwise, clear the selection to disable it. ClearOne recommends leaving this setting on. This setting helps maintain maximum audio intelligibility by allowing only one mic to gate on to a participant’s voice. 1st Mic Priority allows more than one microphone to be activated at same time—it simply restricts mics from gating on to the same audio source.
43 System Configuration ~ Inputs and Outputs Optimizing input gain structure How you adjust an input’s gain directly affects sound quality. The optimal input gain setting is one which is adjusted as high as possible above the noise floor without introducing clipping. Clipping can cause distortion which can damage amplifiers and loudspeakers. To adjust the input level properly, place a signal on the input at the maximum level it will generate.
44 System Configuration ~ Inputs and Outputs Inputs 5–8 The XAP 400 supports 4 line level only inputs for auxiliary audio sources such as video codecs and CD players. To open the Inputs 5–8 configuration window, click the Inputs 5–8 button on the Flow Screen. The In 5–8 button on the Matrix Screen will also open this window. These non-gated inputs are balanced. The nominal input level is 0dBu. Figure 3.46. Input 5-8 Configuration window To select an input channel, click a blank area in the input pane.
45 System Configuration ~ Inputs and Outputs Gain The Gain slider on the selected input in the Inputs 5–8 window is used to adjust input volume level. • Max adjust Use the Gain slider to adjust input volume level. You can also enter the level directly in the decibel box below the gain scale. Min adjust Min/Max limits Use the yellow and blue upper and lower limit arrows on the Gain scale to create Figure 3.47. Gain adjust on line level input minimum and maximum gain level limits.
46 System Configuration ~ Inputs and Outputs Outputs 1–9 The XAP 400 has eight line level outputs for sending audio to video codecs, recorders, or amplifiers. Output 9 is the 10W speaker amplifier output. To open the Outputs 1–9 configuration window, click the Outputs 1–9 button on the Flow Screen. The Outputs 1–9 button on the Matrix Screen will also open this window. Figure 3.49. Outputs 1-9 configuration window These line level outputs are balanced. The nominal output level is 0dBu.
47 System Configuration ~ Inputs and Outputs passing NOM information. Enable NOM if you want to place this output in a constant gain mode. Default is on. When enabled, the NOM button light illuminates green. Gain The Gain slider on the selected output in the Outputs 1–9 window is used to adjust output gain level. • Use the Gain slider to adjust output volume level. You can also enter the level Max adjust Min adjust directly in the 0.0dB box.
48 System Configuration ~ Expansion Buses Expansion Buses Routing of audio to the expansion buses is done in the Matrix Screen. See page 30. For information on setting up an expansion bus network, see page 11. ✍ From Expansion Bus O–Z Click the From Expansion Bus O–Z button on the Flow Screen to open the From Expansion Bus Labels window. You can also access this window from the Matrix Screen. Figure 3.51.
49 System Configuration ~ Processing Processing Processing A–D There are four processing blocks in the XAP 400, each with filters, compressors, and delay to provide pinpoint audio configurations. To open the Processing configuration window, click the Processing A–D button on the Flow Screen. The To and From Processing buttons on the Matrix Screen will also open this window. ✍ ClearOne recommends using the XAP to mute mics instead of using the mute provided by some microphones.
50 System Configuration ~ Processing Figure 3.54. Compressor Setup window Group ✍ Compressors and compressor groups can be established only within the XAP 400 unit being configured, i.e., they cannot be configured from a single point across multiple units. Use the slider to assign this compressor to a compressor group. The default is None. When you assign a compressor to a compressor group—such as a group of three, configured for bass, midrange, and treble—the compressors will monitor each other.
System Configuration ~ Processing Ratio Ratio changes the rate of compression applied to the input signal as the signal exceeds the threshold level. The range is 1:1 to 1:20dB. Default is 1:1. Attack Attack determines how quickly compression is enabled. It is calibrated in milliseconds. The range is 0 to 100ms in .5ms steps. Default is 10ms. Release Release determines how quickly compression is disabled. The range is 100ms to 2 seconds, in 5ms increments. Default is 500ms.
52 System Configuration ~ Processing The frequency response and phase vs. frequency of the total transfer function of all filters is displayed in the window. Each filter can be disabled without affecting the filter settings. All filters can also be disabled using a single command. By default, they are not enabled and the filter types are not defined. Below is a description of each feature in the window. Active Filter The Active Filter displays the filter that is applied to the processing channel.
53 System Configuration ~ Processing Figure 3.56. Low/Mid/High Loudspeaker Driver configuration Refer to the figure above. Note that as you create filters across several processing channels, you can observe their crossover points and general shape of the frequency response. In this case, several Linkwitz-Riley filters are being created across three processing channels to establish a balanced frequency response from low-frequency, midrange, and high-frequency transducers.
54 System Configuration ~ Processing Introducing an appropriate amount of delay to the forward-mounted driver(s) re-establishes the acoustical alignment necessary for proper sound imaging in a room. The same principle of introducing delay applies to separate speaker enclosures located various distances from the listening area. Other types of delay to consider when establishing delay parameters are delays which occur naturally as a result of processing operations within the XAP 400.
55 System Configuration ~ Telco Setup Telco Setup The XAP 400 has a built-in telephone interface that may be configured to meet the requirements of different installations. The default settings will work for most installations. To configure telco settings 1. Click the Telco Config button on the XAP 400 Flow Screen. 2. The Telco Configuration window opens. Adjust settings as necessary. Refer to Figure 3.59.
56 System Configuration ~ Telco Setup Feature Description Receive Reduction This feature ducks receive audio coming in through the telephone line when transmit audio is present. This feature is typically used in applications where the transmit party needs control of the conversation. When activated, the receive audio is ducked by 6dB. Receive Reduction can be turned on or off. The default is off. Auto Answer The XAP 400 can be programmed to answer after one complete valid ring has been detected.
57 System Configuration ~ Telco Transmit and Receive Telco Transmit and Receive Telco Transmit To open the Telco Transmit configuration window, click the Telco Transmit button on the Flow Screen. The T button on the Matrix Screen will also open this window. Mute Mute mutes the audio being sent down the telephone line to the distant location. The light on the button illuminates red when Mute is activated. Default is off (unmuted).
58 System Configuration ~ Telco Transmit and Receive Telco Receive To open the Telco Receive configuration window, click the Telco Receive button on the Flow Screen. The R button on the Matrix Screen will also open this window. Mute Mute mutes the audio being received from the phone line. The light on the button illuminates red when Mute is activated. Default is off (unmuted). ALC Automatic level control (ALC) may be selected on the telco input.
CHAPTER 4: Advanced Configuration Presets Overview For many audio conferencing applications, a great deal of system flexibility is needed to meet the challenges presented by changing meeting or conference room requirements. These requirements may include changes in muting, audio sources, room orientation, or room combining. And ideally, these changes are made instantaneously—without interrupting or affecting any meetings in progress.
60 Advanced Configuration ~ Presets G-Ware Toolbar G-Ware Menus Preset Configuration Pane Preset Matrix Screen Status Bar Figure 4.2. Preset Mode Matrix Screen The Matrix Screen in the Preset Mode is very similar to the Matrix Screen in Configuration Mode. All Input, Output, Processing, and Telco configuration windows can be accessed by clicking on their respective buttons. You can also create custom labels by clicking on the current labels.
61 Advanced Configuration ~ Presets Preset Description. Use the Preset Description box for entering information about the preset. This description is stored in the site file, not the unit. Preset Mask Control/Status B. With Preset Mask Control Status B you can require an active high (H) or active low (L) contact on a control pin (1–19 odd numbers) or combination of several contacts in order to run the preset. A typical use for Preset Mask Control Status B is a room combining Figure 4.4.
62 Advanced Configuration ~ Presets Virtual Reference. The Virtual Reference button opens the preset Virtual Reference window. Using the Virtual Reference window, you can select which signals ✍ To enable Acoustic Echo Cancellation or to change which outputs, expansion bus references, or virtual references will be used for this preset, open the Acoustic Echo Canceller window from the Inputs 1–4 configuration window. will be used by the four Virtual Reference points in this preset configuration.

Enter a description of the preset in the Preset Description box. 2. If you want to password protect this preset, click Protected. See page 26 for information on creating the preset password. 3. 4. Configure the routing matrix and make cross point attenuation adjustments. Configure input, output, processing, and telco channel settings as needed.
64 Advanced Configuration ~ Presets Running presets Presets can be run from G-Ware or the front panel controls on the XAP 400. You can also program external control devices (such as AMX or Crestron, ClearOne Control Panels, XAP IR Remote, and GPIO devices) or use macros to run presets. See Chapter 6: Control for more information on creating custom control. To run a preset using G-Ware Figure 4.7. Execute Preset toolbar button 1. Select the Execute Preset button on the G-Ware toolbar. 2.
65 Advanced Configuration ~ Presets Figure 4.9. Assigning a state to a preset command in the Macro Editor If a preset is flagged as “On,” nothing will happen when the preset is executed again because the system knows it has already been run. This prevents any manual adjustments that are made during the course of the meeting (gain, muting, etc.) from being lost. Room combining example In the room combining scenario depicted in Figure 4.

150 Glossary Glossary Acoustic Echo Cancellation (AEC) A process in which acoustical echo is removed from a signal. AEC can be used to remove unwanted signals from mic audio if the unwanted acoustic signal is available separately as an electronic signal. Adaptive Ambient This portion of the mixer monitors the varying ambient noise level in the room and changes the threshold level at which a microphone gates on.
Glossary Auxiliary audio Audio that comes from line level audio sources such as video codecs, TH2s, and CD players. Bandwidth The difference between the lower and upper 3dB end points of an audio band. Also, the range or differences between the limiting frequencies of a continuous frequency band. Baud Rate The number of signal transitions per second, or the clock rate of the serial bit stream in hertz.
152 Glossary • Butterworth A crossover using a low-pass filter design characterized by a maximally flat magnitude response. This results in no amplitude ripple in the passband. • Linkwitz-Riley A fourth-order crossover consisting of a cascaded secondorder Butterworth low-pass filter. Offers a vast improvement over the Butterworth crossover and is the de facto standard for professional audio active crossovers. Cross point The intersection between an input and an output in the routing matrix.
Glossary EC Reference summing The ability to include multiple signals in a single reference. See also Virtual Reference. ERL Found in the Acoustic Echo Canceller window, the echo return loss (ERL) meter shows the coupling between the reference signal and the input to the echo canceller—the ratio of the two levels.
154 Glossary First Mic Priority Increases the audio level required to gate on additional microphones after the first mic is on. This helps ensure that only one mic gates on when a person speaks. Flow control The regulation of the transmission and reception of data. Flow Screen The Flow Screen is the main access window for G-Ware features and unit configuration. It also shows a detailed block diagram of the audio signal— presenting a graphical explanation of each stage in the signal path.
Glossary Hold Time The length of time that a microphone remains on after the voice (input) level drops below the gate ratio. This can be used to prevent the microphone from gating off during brief pauses in speech. Last Mic Mode Sets the last-activated mic to Last On, Mic 1-8, or Off. The Last On setting leaves the last-activated mic gated on until another mic input gates on. Macro A series of user-created instructions, stored within the unit, which can be executed from an RS-232 command or contact closure.
156 Glossary Noise Cancellation A process through which ambient noise is removed from a signal. Non-linear processing (NLP) NLP increaess the power of echo cancellation for difficult acoustical environments. NLP has four settings: Soft (6dB), Medium (12dB), Aggressive (18dB), and Off. NLP settings are found in the Acoustic Echo Cancellation window. Number of Open Mics (NOM)/Constant Gain Mode Adjusts the output level based on the number of mics gated on and routed to an output.
Glossary required to allow remote modem access. • Preset The preset pasword is created in the Unit Properties window and makes it possible to lock certain presets. A locked preset can be executed without the password. However, a password must be entered to edit the preset. • Site file (File Access) The site file password is set in the Site Properties window and will lock the site file. Users must enter the password in order to open the site file.
158 Glossary Reverberation A diffused acoustic energy field fed and maintained by sound reflections from the room surfaces. S–Z buses These eight buses are defaulted as auxiliary mix buses. They are used to route auxiliary audio to and from other units on the network. These buses are also used as mic mix buses when NOM count is not required. Serial Command A bit description designed to execute an instruction or command.
Glossary TERLE The telco echo return loss enhancement (TERLE) meter shows the loss through the telephone echo cancellation process. It is the ratio of the two levels. Threshold The upper or lower level at which a signal processing mechanism begins or terminates operation. Transmit audio Audio being sent to the telephone line (To Telco). Unit properties The Unit Properties window opens when you add a new unit to the site.
