  • 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 19). 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 on the processor block. This action opens a new window with a dialog box that contains parameters for the processor (see figure 21).

  • Page 36: Mic/Line Input Signal Controls

    Mic/Line Input Signal 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 input signal level readout below the fader.

  • Page 37: Filter (Filt)

    Filter (FILT) Each filter block allows a total of five filters. The first filter is inserted from a processor list that appears when the block is double-clicked or from a context window that shows a processor list when the block is right-clicked. Figure 22.
  • Page 38 Figure 23. Filter Block Dialog Box Additional filters are inserted using the open filter block dialog box, and selecting a filter type from the drop-down filter selection list. All filter parameters are modified using the Filter block dialog box. Each filter is loaded with all applicable default parameters displayed to the right of each drop-down filter selection list.
  • Page 39 Figure 24. 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 how box 3 (see figure 24) is highlighted in yellow, indicating it is the filter in focus.
  • Page 40 Figure 25. Filter Dialog Box, Filter Not Bypassed Above the graph, each filter has a "handle" (circled in red above for the parametric EQ filter) placed directly above the cutoff or center frequency. The handle number corresponds to the filter number (also outlined in red). Clicking a handle or clicking the table row brings focus to that filter.
  • Page 41 High Pass The high pass filter allows frequencies below the specified frequency to pass unattenuated. All frequencies below the cutoff are attenuated. The default cutoff is 100 Hz. Figure 26. High Pass Filter Response Curve All frequencies lower than the specified frequency (in this example,100 Hz) are attenuated leaving the upper frequency response flat.
  • Page 42 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. Figure 27. Low Pass Filter Response Curve Here, the frequencies higher than the specified frequency, 10 kHz, are attenuated leaving the lower frequency response flat.
  • Page 43 Bass and Treble Shelving Bass and treble shelving can be added to the filter. Also 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 44 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. Up to five parametric filters can be placed in the filter box at one time.
  • Page 45 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 30). Parametric filters can be used to notch out a very narrow, or very wide range of frequencies using the Q setting.
  • Page 46 The overall frequency response is now shown as a solid red line with the filter in focus (located in row 3 in figure 31) shown in the color of its table row. Figure 31. All Parametric Filters Active The parametric filter allows frequency selection accurate to 0.1 Hz and either 6 or 12 dB of slope.

  • Page 47: Feedback Suppressor (Fbs)

    Feedback Suppressor (FBS) The Feedback Suppressor is used in live situations when there is an indication of feedback during live operation. Dynamic filters automatically detect feedback on a live microphone channel, and engage a set of up to 5 fixed and 15 dynamic filters to counteract frequency peaks at the detected feedback frequency.
  • Page 48 FBS Settings tab enables selection of the feedback suppressor parameters. Settings • For Composite View show: — The graph view is set by one of three buttons: Only Dynamic FBS Filters • Only Fixed FBS Filters • (default) Dynamic & Fixed FBS Filters •...
  • Page 49 FBS Dynamic Filters This tab contains the fifteen dynamic filters, with a scroll bar to display filters hidden due to dialog box size. Dynamic filters are notch filters that are cut only, providing attenuation up to 30 dB at the specified Q. The default Q is set in the menu, but can be changed on Tools>Options the settings tab prior to engaging the FBS dynamic filters.
  • Page 50 FBS Fixed Filters 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 made manually from the tab.

  • Page 51: 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 52 Automatic Gain Control (AGC) AGC adjusts the gain level of a signal based upon 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 (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 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 any noise level in the environment or source equipment.

  • Page 56: Delay (Dly)

    Delay (DLY) The delay processor, when inserted, provides a means to delay the audio signal. Audio delay syncs audio to video or can time-align speakers placed at different distances from the listener. The DMP 64 can set delay by either of two criteria: time or distance (feet or meters).

  • Page 57: Ducking (Duck)

    Ducking (DUCK) Ducking provideds 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 Configuration Ducking is configured in a dialog box that opens when an active ducking processor block is double-clicked (see figure 37 on the previous page). Current source indicator Shows the input selected as the ducking source. Ducker settings affect the input channel shown here.
  • Page 59 Priority Displays the hierarchy of ducking source to duck targets (see Ducking Priority below). Priority levels are displayed in tree fashion. Click an input channel to select that channel as the current source. The current source indicator ( a ) reflects the selected input channel. By (dB): (Target gain reduction amount) Individual attenuation settings for each duck target in dB.

  • 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: Pre-Mixer Gain (Gain)

    Pre-mixer Gain (GAIN) The post-input processing gain control (also called the pre-mixer gain) provides gain or attenuation post-processing gain block. It includes a mono long-throw fader with a – 100.0 to +12.0 dB gain range, and a current level setting readout below the fader. Fader adjustments are in 1 dB increments, while adjustments can be entered manually to 0.1 dB resolution.

  • Page 62: Line Output Channels

    Line Output Channels There are four mono line output channels. Controls and processing blocks, identical for each output channel, are described in the following sections. Loudness (LOUD) The loudness processor, when inserted, applies a filter compensation curve to the signal in an inverse relationship to the output volume control setting.
  • Page 63 Calibrating Loudness The user can fine-tune the amount of loudness compensation using the compensation adjustment slider and adjusting "by ear," or by measuring SPL levels in a particular room, then using the slider to adjust the loudness filter relative to the SPL of the room and system gain structure.

  • Page 64: Delay Block (Dly)

    Set the slider to 0, the center point. Disengage the loudness . The Calibrate Bypass result is a moderate enhancement to the program material, with more accentuated bass frequencies (below 500Hz), and more brightness in the high frequencies that carry harmonic content (above 7kHz). Engage and disengage the switch in Bypass order to “A/B”...

  • Page 65: Volume Control (Vol)

    Volume Control (VOL) Each output channel volume block provides a mono long-throw fader with a range of 0 to 100 dB of attenuation, 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.

  • Page 66: Virtual Bus Returns

    Virtual Bus Returns There are four mono virtual bus return inputs, fed by the virtual bus sends. Channel controls and processing blocks described in the sub-sections that follow are identical for each virtual bus return channel, A through D. The virtual bus is used when additional processing of an input signal is required. It is also useful to apply identical filtering, dynamics processing, loudness compensation, or signal gain/attenuation to multiple inputs.

  • Page 67: Primary Mix Matrix

    Primary Mix Matrix The DSP architecture contains a primary mix matrix that connects the mic/line inputs and virtual bus returns to the line outputs. The DSP Configurator user interface provides control of the primary mix matrix, used to set mix levels from the post processing inputs and post processing virtual returns to each line output bus.

  • Page 68: Mix-Point Behavior

    Mix-point Behavior: No mix information — A faint gray circle on the mix-point indicates it is muted (contains no mix information). Mix information — A solid teal-colored circle indicates the mix-point contains mix information (the mix-point is unmuted). Mouse-over — The cursor changes to a hand when a mouse-over occurs at a mix-point, whether the mix-point contains mix information or not.
  • Page 69 Clicking a mix-point brings focus to that mix-point. A circle appears around the teal mix-point which remains transparent. Double-clicking a mix-point opens a configuration dialog box with the following components: • Mono Fader — Sets the signal level from the selected input to the output bus.

  • Page 73: Secondary Mix Matrix

    Secondary Mix Matrix The DSP architecture contains a secondary mix matrix that connects the mic/line inputs and virtual bus return signals to the virtual bus sends. The DSP Configurator user interface provides control of the secondary mix matrix, used to set levels from the post-processing input line and virtual bus return signals to the virtual bus sends.
  • Page 74 In the example below (see figure 45), input 1 is sent to the virtual bus send by muting all four signals on the input 1 primary mix-points. The virtual bus now serves as additional signal processing for the input. The signal routes over virtual bus A and through the signal chain before being sent to the virtual bus return mix-point and output 1.

The analog to digital converters (ADC) and digital to analog converters (DAC) sample at 48 kHz 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 95: About Setting Gain Structure

    About Setting Gain Structure There are two approaches the system designer can take in setting up gain structure, depending upon where output volume is to be controlled. The output volume of the DMP 64 can be controlled by either of the following two gain blocks (see figure 58 on the previous page): •...

  • Page 96: Adjusting Pre-Mixer Gain

    Adjusting Pre-mixer Gain After setting input gain, add desired processors into the input signal chain (see figure 58 on page 88). The pre-mixer gain control ( b ) 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 97: 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 (see figure 58 on page 88). To set the mic/line input and mix levels: Connect a microphone to input #1. Double-click the mix-point ( c ) for mic/line 1 to output 1 to open the dialog for that mix-point, then unmute the mix-point to place the signal into the mix.
