Figure 16. Control Blocks and Processor Chains audio Level, Mix-point, Processing Blocks, and signal chains As outlined in red above (see figure 16), all control blocks on the main DSP control screen have one of three main functions in the overall signal chain: •...
Page 34: Level Control Blocks
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.
Page 35 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).
Page 36: Mic/Line Input Signal Chain Controls
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.
Page 37 • 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.
Page 38 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.
Page 39 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.
Page 40 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.
Page 41 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.
Page 42 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.
Page 43 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.
Page 44 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.
Page 45 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.
Page 46: Acoustic Echo Cancellation (Aec)
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.
Page 47: Activity Leds
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 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.
Page 48 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). •...

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.
Page 50: Dynamics (Dyn)
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.
Page 51 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.
Page 52 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.
Page 53 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.
Page 54 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.
Page 55: Delay (Dly)
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).
Page 56: Ducking
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.
Page 57 Ducking configuration Ducking is configured in a dialog box that opens when an active ducking processor block is double-clicked. 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.
Page 58 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.
Page 59: Ducker Tutorials
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, Right-click the box to open context -or- then click Ducker menu, then click Insert Ducker Once inserted, double-click on the ducker block to open the ducker configuration dialog box.
Page 60: Automix (Am)
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.
Page 61 • 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.
Page 62 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.
Page 63: Pre-Mixer Gain (Gain)
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.

To calibrate loudness, use a sound pressure level meter set to “C”...
Page 67: Delay Block (Dly)
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).
Page 68: Volume Control (Vol)
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.
Page 69: Virtual Bus Returns
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.
Page 70 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.

Page 72 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.
Page 73 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).
Page 74: Virtual Bus Returns, E-H
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)
Page 75: Output Mix Matrix
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).

Page 77: Mix-Point Behavior
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).
Page 78 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 Mix-point selected input to the output bus.
Page 79: Mix-Point Examples
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.
Page 80 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.
Page 81 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.
Page 82: Virtual Send Bus Mix Matrix
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.
Page 83 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.
Page 84: Expansion Outputs Mix Matrix
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.
Page 85: Extron Exp Bus
This has no bearing on how audio is transported from unit to unit, making it unimportant which unit is set to primary. notE: You can connect a DMP 128 AT to a non-AT unit by the EXP ports, however be aware that the AT unit defaults to the primary unit and cannot be changed.

Page 106: Optimizing Audio Levels
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.
Page 107: About Setting Gain Structure
The remainder of this section references the gain, trim and volume controls outlined in figure 63. Figure 63. Gain, Trim and volume Controls Mic/Line input gain Mix-point gain Output volume Pre-mixer gain 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.
Page 108: Setting Input Gain
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.
Page 109: Adjusting Trim
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.
Page 110: Setting Mic/Line Input And Mix Levels
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: Connect a microphone to Input #1. 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.
Page 111: Signal Path Building Blocks
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.

Building Blocks Select Lavalier by placing the mouse over the text Lavalier. The selected text changes color and is underlined.
Page 113: Adding A Building Block
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.
