Variable/fixed select section
The M3000A’s GA (Group/Aux) diversity function
allows MIX buses 1–8 to function either as group
buses or as AUX buses. In this section, you can switch
each pair of MIX buses (1/2, 3/4, 5/6, 7/8) between
functioning as group buses or as AUX buses.
A Variable/fixed select switches
These switches select whether the level of the signals
sent from the input channels to MIX buses 1–8 will be
fixed (FIX) or variable (VARIABLE). From top to bot-
tom, these switch MIX buses 1/2, 3/4, 5/6 and 7/8.
●When FIX ( ) is selected
The corresponding pair of MIX buses (1/2, 3/4, 5/6, 7/
8) will function as a group bus, and the signal of the
MIX (FIX) bus will be output to the corresponding
mix channel. In this case, the settings of the mix level
controls M1–M8 (mono input channels J, stereo
input channels 7) will have no effect.
●When VARIABLE ( ) is selected
The corresponding pair of MIX buses (1/2, 3/4, 5/6, 7/
8) will function as an AUX bus, and the signal of the
MIX (VARIABLE) bus will be output to the corre-
sponding mix channel. In this case, the mix level con-
trols M1–M8 (mono input channels J, stereo input
channels 7) will take effect just as they are set.
