GA32/12, GA24/12—Owner’s 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.

Notes:

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.

Features

•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.
