Yamaha ga24-12 User Manual

 

Introduction

 

Thank you for choosing the Yamaha GA32/12 or GA24/12 mixing console. Please read 
this manual thoroughly to take best advantage of the console and extend its useful life.

 

This manual has been written on the assumption that you already understand the basic 
operation and technical terminology of mixing consoles.

Descriptions of GA24/12 specifications appear in brackets ({}) if they differ from the 
GA32/12.

 

• The GA32/12 provides 28 monaural and 2 stereo 

input modules {the GA24/12 provides 20 mon-
aural and 2 stereo input modules}. The output 
channels comprise stereo outputs, 10 mix out-
puts, and two matrix outputs, and support a wide 
range of applications, from SR (sound reinforce-
ment) to facility acoustics.

• Each monaural input channel offers a 26 dB pad, 

HPF, phase switch, 4-band EQ (HI-MID and LO-
MID frequencies are variable), and a 100 mm-
long full-stroke fader. Also, phantom power can 
be turned on and off for every group of four 
inputs.

• Four stereo AUX returns and TAPE IN jacks are 

provided as standard.

• The master section of the console is located in the 

center area of the unit, facilitating operation.

• The master section provides output channels for 

MIX buses 1–10, with EQs and 100 mm-long 
faders.

• Each input channel and four stereo AUX returns 

include a PFL switch, and stereo bus, MIX buses 
1–10, and Matrix 1–2 has an AFL switch, 
enabling you to monitor the input/output 
sources quickly.

• Using the GA Diversity function enables you to 

set MIX buses 1–4 to Variable mode or Fix mode 
individually. In Variable mode, you can change 
the level of the signals sent out from the input 
channels. This routing can be used as a conven-
tional AUX bus. In Fix mode, the level of the sig-
nals sent out from the input channels is fixed. 

This routing can be used as a conventional group 
bus. In this way, you can configure the bus for a 
specific purpose.

• The console has two independent matrixes. You 

can mix MIX buses 1–4 and the stereo bus indi-
vidually at the levels you desire and output them 
from the MATRIX OUT 1–2 jacks. This routing 
can be used as a mix for the foldback or for indi-
vidual speakers and amplifiers.

• The INSERT I/O jacks are provided for all mon-

aural input channels, the stereo bus, and MIX 
buses 1–4. You can insert an external effect pro-
cessor, if necessary.

• Talkback signals can be sent to any of MIX buses 

1–4, MIX buses 5–10, and the stereo bus.

• C-R monitor output enables you to select PFL/

AFL or TAPE IN as a monitoring source.

• The console’s sturdy finish and rugged design 

assure its durability even under severe conditions 
and rough on-site usage.
