Crest Audio X-SERIES X 20R - Manual (Page 29)

Bus Assignment Features
The bus assignment section offers considerable flexibility for creating what eventually becomes the
main output mix. Two stereo subgroups are available for creating submixes or separate stereo
mixes. When the channel is being used as a stereo input, Left/Right, Groups 1/2, Groups 3/4 and
bus assignments are configured as true stereo pairs. Bus assignments are derived post-fader, post-
EQ, and post-mute.
BAL Control
The balance control adjusts the stereo balance into the Left/Right and Group-Pair buses.
MUTE
The input channel is muted and the MUTE LED is illuminated. All AUX feeds (See Aux
options for exceptions) and bus assignments are also muted. Insert send and SOLO signals
remain active.
Mono Bus Assign
The channel is assigned to the MONO mix bus. The Left and Right signals are summed to
make up the MONO signal. The BAL control has no affect on the MONO assign.
L-R Bus Assign
The channel is assigned to the Left and Right mix buses.
G 1-2 Bus Assign
The channel is assigned to Groups 1 and 2. Groups 1 and 2 are normally used as a stereo
pair. They can also be treated as two discrete mono groups by using the BAL control as
GROUP 1/2 mix control.
G 3-4 Bus Assign
The channel is assigned to Groups 3 and 4. Groups 3 and 4 are normally used as a stereo
pair. They can also be treated as two discrete mono groups by using the BAL control as
GROUP 3/4 mix control.
Input Fader
The fader is the primary level control for signals being sent to any of the console's mix buses.
The signals affected are the AUX sends selected to be post-fader (See Aux Send section) and
the Mono, L/R and Groups 1-4.
PK / SIG LED Indicator
This two-color LED is used to monitor both the channel’s Left and Right signal levels. Signal
present (green) is monitored pre-fader. Peak (red) is monitored at the preamp and both
before & after the fader.
PFL
The PFL (Pre Fader Listen) button routes the channel’s signal to the PFL bus for monitoring
through headphones or in the control room. The Peak (red) LED is illuminated to show
PFL status. Since the SOLO bus is stereo, the channel’s stereo image is preserved within the
Solo system.
