A Source select switch This switch enables you to select the signal source to be displayed on 1 the MATRIX (PFL•AFL/TAPE) meter (Meter bridge 3) in the right corner of the level meter. When the switch is set to PFL-AFL/TAPE ( ) PFL•AFL/TAPE MATRIX METER SELECT The meter indicates either the PFL/AFL bus output level or the input level of the signals sent from the TAPE IN jacks, depending on the setting of the Monitor source select switch in the C-R MONI section. When the switch is set to MATRIX ( ) The meter indicates the output level of Matrix 1 and 2. Meter bridge This peak level meter indicates the output level of the MIX buses, ST bus, Matrixes 1/2, PFL bus, and AFL bus, and the level of the signal input from the TAPE IN jacks. 1 234 PEAK +8 +5 +3 +1 0 –1 –3 –5 –7 –10 –15 –20 PEAK +8 +5 +3 +1 0 –1 –3 –5 –7 –10 –15 –20 PEAK +8 +5 +3 +1 0 –1 –3 –5 –7 –10 –15 –20 PHANTOM POWER M1 M2 M3 M4 M5 M6 M7 M8 M9 M10 L ST1 MATRIX R 1 2 PFL•AFL / TAPE L R 5 A M1–M10 meters These meters indicate the output level of MIX OUT 1–10.

D POWER indicator When the power to the GA32/12 (or GA24/12) is turned on, this indicator lights up. E PHANTOM indicator This indicator lights up when any of the phantom power supplies (see page 16, rear panel 4) are turned on.

Usually their nominal input levels range from –16 dB to –60 dB. However, when the pad switches (see page 2, front panel 1) are turned 2 (hot) on, the nominal input levels range from +10 dB to –34 dB. For every group of four input channels, the INPUT A jacks have phantom power of +48 V that can be turned on and off. See the figure on the right for wiring. B INPUT B jacks 1–12, 17–32 {1–12, 17–24} These are balanced TRS phone, monaural input Tip (hot) jacks. Their nominal input levels are the same as 1/4" TRS phone plug Ring (cold) those for INPUT A 1. You cannot use the INPUT A jack and INPUT B jack for the same channel simultaneously. Do not connect plugs to both A Sleeve (ground) and B jacks of the same channel at the same time. Otherwise, a malfunction may occur. Phantom power is not available for the INPUT B jacks. See the figure on the right for wiring. C INSERT I/O jacks 1–12 These TRS phone jacks are used to insert an external processor into monaural input channels 1–12, 17–32 {17–24} with nominal input/output levels of 0 dB.

If one of these switches is turned on, the PHANTOM indicator on the Meter bridge will light up. GA32/12, GA24/12—Owner’s Manual Rear Panel 17 E INPUT jacks 13–16 These are unbalanced phone jacks for the stereo input channels, with nominal input levels ranging from –34 dB to +10 dB. If you are using the stereo input modules as monaural channels, connect a plug to 13L (MONO) or 15L (MONO) jack. See the figure on the right for wiring. F MIX OUT 1–10 jacks These balanced XLR-3-32 jacks output MIX bus 1–10 signals individually, with a nominal output level of +4 dB. See the figure on the right for wiring.
