• The GA32/12 provides 28 monaural and 2 stereo input  modules. The output channels comprise stereo outputs, 10 mix  outputs, and two matrix outputs, and support a wide range of  applications, from SR (sound reinforcement) to facility  acoustics.  • Each monaural input channel offers a 26 dB pad, HPF,  phase switch, 4-band EQ (HI-MID and LOMID frequencies are  variable), and a 100 mmlong 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  conventional AUX bus. In Fix mode, the level of the signals  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 individually 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  individual speakers and amplifiers. • The INSERT I/O jacks are provided for all monaural input  channels, the stereo bus, and MIX buses 1–4. You can insert  an external effect processor, 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.
