Yamaha ga24-12 User Manual

Master Section

The GA32/12 and GA24/12 feature a GA (Group/Aux) diversity function, which enables you to 
use the MIX bus 1–4 signals as group bus signals or AUX bus signals. This section of the console 
allows you to select whether you wish to use MIX buses 1–4 as group buses or AUX buses.

A

These switches are used to select whether the level of signals sent from the input channels to 
MIX buses 1–4 will be fixed (FIX) or variable (VARIABLE).

■ When FIX is on:

The selected MIX bus(es) function as a group bus. The 
level of the signal from each input channel will be fixed, 
and the M1–M4 mix level controls of the input channels 
that correspond to the MIX buses will be disabled.

■ When FIX is off:

The selected MIX bus(es) function as an AUX bus. Signals 
that pass through the M1–M4 mix level controls of each 
input channel (see page 2, monaural input channel 

8

, and 

page 4, stereo input channel 

6

) are sent to the 

corresponding MIX buses.

This section consists of the output channels that handle MIX bus 1–10 signals individually. 
Signals that pass these output channels are output from MIX OUT 1–10 jacks (see page 17, rear 
panel 

6

), and also routed to the AFL bus. MIX bus 1–4 signals are also routed to the ST bus 

and Matrixes 1/2.
