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).
