  • Page 38: Flexinput Channels

    FlexInput Channels The eight AEC-enabled inputs offer FlexInput capability to route a Dante channel in place of a local mic/line input. The flexible input selection enables audio processing from remote wireless microphones, wallplates, and other sources from the Dante network. Gain Control (GAIN) Each input provides gain control to accommodate consumer and professional analog and digital line level sources and microphones.

  • Page 40 A balloon number appears at the top of the frequency graph display (see figure 26, corresponding to the row number underneath the graph. The location of the balloon number is at the frequency selection of that row. Figure 26. 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.
  • Page 41 When multiple filters are enabled, the graph indicates the focused filter result (independent of other filters) in the color of the filter row in table. The composite response, the combined effect of all filters not bypassed, is always displayed in red. Figure 27.
  • Page 42 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 28. High Pass Filter Response Curve In figure 28, all frequencies lower than the specified frequency, 100 Hz, are attenuated leaving the upper frequency response flat.

  • Page 43: Low Pass

    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 29. Low Pass Filter Response Curve Here, the frequencies higher than the specified frequency, 10 kHz, are attenuated leaving the lower frequency response flat.
  • Page 44 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 45 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 46 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 32). Using the Q value, parametric filters can be used to notch out a very narrow, or very wide range of frequencies.
  • Page 47 The overall frequency response is now shown as a solid red line with the filter in focus located in row 3 (see figure 33 below) shown in the color of its table row. Figure 33. All Parametric Filters Active The parametric filter allows frequency selection accurate to 0.1 Hz and either 6 or 12 dB of slope.

  • Page 48: 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 49 If you do want the reference signal to track with changes in listening volume, and want more control over the actual reference level: Route the far end signal to both the amplifier output and the virtual (unused) output. Create a group master control that contains the amplifier output and virtual output. Set soft limits for the group master control, as desired.

  • Page 50: Advanced Aec Controls

    Select Reference Select the AEC reference from a drop-down list, populated with the following: Output channels (1 to 8) • • Input channels (1 to 12) • Virtual Return channels (A to H) Noise Cancellation Noise cancellation can be switched on or off from the AEC dialog. The noise canceller detects steady state noise, such as HVAC or other continuous system noise, and effectively remove it without causing audible artifacts.

  • Page 51: Dynamics (Dyn)

    Additional Controls • Double Talk Echo Reduction – sets the amount of echo reduction applied during double-talk. The range is 0.0 to 20.0 dB in 0.1 dB increments. Default is 15.0 dB. • Comfort Noise – sets a comfort noise level in dB to eliminate states of complete silence, which could be perceived as a failed connection.
  • Page 52 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 53 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 54 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 55: Noise Gate

    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 56: 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 57: 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 58 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 59 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 60: 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 61: 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 62 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 63 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 64: 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 37, Automix Groups Dialog on the previous page).

  • Page 68: 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 50).

  • Page 69: 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 adjusts with the slider or by entering the desired level directly into the volume setting readout in 0.1 dB increments. Click the fader handle or click within the fader area to bring focus to the fader.

  • Page 70: 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 71 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 73 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 74 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 43).

    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 32). 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 76: 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 44 on page 71).

  • Page 78: 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 79 Click a mix-point to focus it. 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 Mix-point input to the output bus.

  • Page 80: 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 45. Input 1 to Output 1 In the first example (see figure 45) input audio from Input 1 is processed and arrives at the output 1 matrix mix-point.
  • Page 81 Figure 46. All Inputs to Output 1 In the next example (see figure 46), 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 the individual signal levels for the desired balance.
  • Page 82 Figure 47. Input 1 to All Outputs In the example in figure 47, input 1 is 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 83: 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 84 In the example in figure 49 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 85: Expansion Outputs Mix Matrix

    Expansion Outputs Mix Matrix The DSP architecture contains a third mix matrix that supports connection of a second DMP 128 using the included shielded CAT 6 cable. If the included cable is not long enough use shield CAT 6 wired in a straight through configuration up to 35 feet (10 meters). The output connects the mic/line inputs and virtual returns to the Expansion Outputs.

  • Page 86: 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 107: 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 108: About Setting Gain Structure

    The remainder of this section references the gain, trim and volume controls outlined in figure 69. Figure 69. 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 109: 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 110: Adjusting Pre-Mixer Gain

    Adjusting Pre-mixer Gain After setting input gain, add desired processors into the input signal chain. The pre-mixer gain control (see figure 69 on page 102, ) 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.

    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 69 on page 102, ) 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 112: 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.
