Relationship between analog and digital gain while Gain
Compensation is on

If Gain Compensation is on, adjusting the analog gain by a specific amount will cause the I/O device to
output to the audio network a signal that is attenuated by the same amount. Therefore, the signals on
the audio network will maintain a constant corrected level in the digital domain.
For example, assume that the analog gain value has been set to +30 dB and Gain Compensation is now
turned on. Under this condition, if you raise the analog gain value to +45 dB, the level of the signal sent
to the audio network will stay at +30 dB (that is, attenuated by –15 dB).

At this time, the gain of each signal input to the CL series unit will be adjusted by the digital gain
parameter of the CL series console. If the FOH console and the monitoring console are sharing one I/
O device, adjusting the analog gain on the FOH console will not affect the input level on the monitoring
console, because the level of the signal on the audio network is maintained at a constant level.
However, please note that if the signal is distorted due to a high level of analog gain, you must first turn
the Gain Compensation function off, set the gain to an appropriate input level, and then turn the
function back on. If you try to lower the analog gain level while the Gain Compensation function is on,
the signal on the audio network will be amplified by the same amount due to the Gain Compensation
function, and the signal will remain distorted.

NOTE

You can perform this operation rapidly if you’ve assigned Gain Compensation on/off for the SET
BY SEL function to one of the USER DEFINED keys.

Sending a signal from an input channel to the
STEREO/MONO buses

This section explains how to send a signal from an input channel to the STEREO bus or MONO bus.
The STEREO bus and MONO bus are used mainly to send signals to the main speakers. There are two
ways to send signals to the STEREO bus or MONO bus: ST/MONO mode and LCR mode. You can
select the mode individually for each channel. These two modes differ as follows.

■

ST/MONO mode

This mode sends signals from the input channel to the STEREO bus and to the MONO bus
independently.
• Signals sent from an input channel to the STEREO bus and to the MONO bus can be switched on or

off individually.

• The panning of a signal sent from an input channel to the STEREO bus L/R is controlled by the TO

ST PAN knob. (Signals sent to the MONO bus are not affected by this knob.)

• The left/right volume balance of a signal sent from an ST IN channel to the STEREO bus is controlled

by this knob. (Signals sent to the MONO bus are not affected by this knob.)
If PAN/BALANCE mode is set to PAN, you will be able to adjust the pan position of signals sent to
the STEREO bus L/R individually (see

page 37

■

LCR mode

This mode sends input channel signals to three buses (STEREO (L/R) and MONO (C)) simultaneously.
• Signals sent from an input channel to the STEREO bus and MONO bus will be switched on or off

collectively.

• The CSR (Center Side Ratio) knob specifies the level ratio between signals sent from an input

channel to the STEREO (L/R) bus and to the MONO (C) bus.

• The TO ST PAN knob/BALANCE knob specifies the level of signals sent from an input channel to

the STEREO (L/R) bus and MONO (C) bus.

NOTE

If you want to monitor the signal of the STEREO bus or MONO bus through headphones or
similar devices, press the MONITOR button in the Function Access Area to select “LCR” as the
monitor source before you continue with the following procedure.
