GA32/12, GA24/12—Owner’s Manual
I ON switches
These switches are used to turn on and off the signals routed from the input channel to MIX
buses 1–4.
J M5–M10 mix level controls
These controls route the input channel signals to MIX buses 5–10. Use the PRE switches K to
select pre- or post-fader.
K PRE switches
These switches are used to select pre- or post-fader for signals sent from the input channel to
MIX buses 5–10. Each switch is effective for one pair of MIX buses: 5/6, 7/8, or 9/10. When you
turn these switches on, the pre-fader signals will be sent to the corresponding MIX bus pair.
L PAN control
This control is used to set the stereo image of signals sent from the input channel to the ST
(stereo) buses.
M ST (Stereo) switch
When you turn this switch on, input channel signals are sent to the ST buses.
N ON switch
This switch is used to turn on and off the corresponding input channel module. When this
switch is turned off, no signals are sent from the corresponding input channel to the ST buses
and MIX buses 1–10. However, using the PFL switch
O will enable you to monitor the signals
via the C-R MONITOR OUT jacks or PHONES jack.
O PFL (Pre-fader Listen) switch
When you turn this switch on, the pre-fader signals of the input channel are routed to the PFL
bus, and you are able to monitor the signals via the C-R MONITOR OUT jacks or PHONES
jack.
P Channel fader
This fader is used to adjust the level of the input channel signals. This fader setting affects the
level of the signals routed to the ST buses, MIX buses 1–4, and MIX buses 5–8 (when the PRE
switches are turned off).
Signal flow of the monaural input channel
Note: When these switches are set to off, no signals will be sent from the input channel to
the corresponding MIX buses regardless of the setting of the switches in the Variable/Fix
select section (see page 6).
