Extron electronic DMP 64 Virtual Bus Returns, Gain GAIN, Filter FILT, Dynamics DYN, Loudness LOUD

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.

Filter (FILT)

Filter function and interface is identical to the mic/line input channel Filter block with the exception that only three filters are allowed (see Filter (FILT) on page 31, for additional information).

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) on page 45 for additional information).

Loudness (LOUD)

There is one loudness processor available on each virtual path. The loudness function and interface is identical to the output channel Loudness block (see Loudness (LOUD) on page 56).

Gain (GAIN)

Each virtual input channel gain block provides a mono long-throw fader with a –100.0 to +12.0 dB gain range, and a level setting readout below the fader. Fader behavior is identical to the pre-mix-point gain block, described in the mic/line input section (see Pre-mixer gain (GAIN) on page 55). Fader adjustments are in 1 dB increments, while adjustments can be entered manually to 0.1 dB resolution.

Default is unmuted at unity gain (0.0 dB).
