An Aux section can be globally switched to stereo using one of the eight “STEREO
AUX” switches located on the CCM. When an Aux section is switched to stereo, the
orange LED between PRE and ON LEDs will illuminate.
When an Aux section is in Mono mode, the dual concentric potentiometer acts as
two level controls, one for sending to the A bus and one for sending to the B bus If an
Aux section is in Stereo mode, the top half of the potentiometer becomes the overall
level control, while the lower section allows you to pan the signal across the A and B
send bus. The 7453 has eight mono Aux Sends.

The MF2 mid frequency control covers the range 400Hx to 4kHz.
The MF1 low/mid frequency control covers the range 60Hz to 600Hz.
The LF low frequency control covers the range 20Hx to 200Hz.
The Q-control varies the bandwidth of the EQ section in the range Q=1 to Q=3. A low
Q-value gives a wide bandwidth. By this follows that a relatively large range of fre-
quencies (either side of the centre frequency) have the cut/boost applied. As the Q-
value is increased, the bandwidth is reduced and consequently a smaller range of
frequencies have cut/boost applied.

The low pass filter has an IN/OUT switch with a variable frequency control from
1.2kHz to 35kHz.
The high pass filter has an IN/OUT switch with a variable frequency control from
14Hz to 400Hz.

These switches allow you to insert the equaliser in series with Input 1 or Input 2 or
both inputs at the same time.

All Input Channels have a Send and Return break-jack facility placed after the equal-
izer. This is to allow the signal to be sent out to and returned from an external pro-
cessing unit. A relay is used to switch the Insert function IN and OUT. When INSERT
is not selected, the signal is passed directly from the EQ stage to the fader.
Select INSERT to divert the channel audio signal to an external device and have the
processed signal inserted into the signal path.

Aux from VCA may be set ON or OFF locally or by programming as part of a cue.
When Aux VCA is ON, the LED will be illuminated.
Aux VCA OFF - If any of the Auxiliary Sends on a channel are set to send signal post
fader, then the channel fader will directly control the signal level sent to the Auxiliary
Mix Bus. A DC Master selected for the channel will have no effect.
Aux VCA ON - If any of the Auxiliary Sends on a channel are set to send signal post
fader, the DC Master will also control the overall level of the signal to the Auxiliary
Mix Bus.

Press the “GROUP +” switch to increment the DC Master group number and the
“GROUP -” switch to decrement the DC Master group number. The DC Master group
selected is shown in the segment display to the right of the switches, labelled
