GA32/12, GA24/12—Owner’s Manual
Signal flow in the AUX RETURN section
MATRIX section
The GA32/12 and GA24/12 provide two matrix modules that allow you to mix MIX buses 1–4
and ST bus signals at desired levels. Matrix 1–2 signals are output in monaural via the MATRIX
OUT 1–2 jacks (rear panel
K).
A M1–M4 level controls
These control knobs enable you to adjust the input level of MIX bus
1–4 post-fader signals.
B L/R controls
These control knobs enable you to adjust the input level of the ST bus
post-fader signals for the L channel and R channel independently.
C LEVEL control
This control knob enables you to adjust the output level of Matrix 1–2 signals.
D ON switch
This switch turns on and off Matrixes 1–2. When you turn this switch
off, the corresponding matrix signal is not output from the MATRIX
OUT jack. The signal is not sent to the AFL bus, either.
E AFL (After-fader Listen) switch
When you turn this switch on, the matrix 1–2 post-fader signals are
sent to the AFL bus. You can monitor the signals via the C-R MONITOR OUT jacks or
PHONES jack. However, this switch will be disabled if the ON switch (
4) is turned off.
