[. . . ] Avoid physical shocks Strong physical shocks to the unit can cause damage. Do not open the case or attempt repairs or modifications yourself This product contains no user-serviceable parts. Refer all maintenance to qualified Yamaha service personnel. Opening the case and/or tampering with the internal circuitry voids the warranty. [. . . ] This fader setting affects the level of the signals routed to the ST buses, MIX buses 1­4, and MIX buses 5­8 (when the PRE switches are turned off). +48V PHANTOM PEAK ON INPUT A 1-12, 17-24/17-32 INPUT B PAD HA HPF 80 26dB GAIN HIGH MIX MIX PFL (FIX) (VARIABLE) 1 2 3 4 1 2 3 4 5 6 7 8 9 10 L R CTL M1 M2 M3 M4 M5 PRE M6 M7 PRE M8 M9 PRE M10 ST LR 4-Stage EQ ø HI-MID g LO-MID g f f EQ LOW ON ON ON ON INSERT I/O ST PAN PFL Signal flow of the monaural input channel GA32/12, GA24/12--Owner's Manual 4 Front Panel Stereo input channels GAIN 1 +10 ­34 2 PEAK 80 3 The GA32/12 and GA24/12 provide two stereo input channel modules. Use the paired INPUT 13/14 and 15/16 jacks (see page 17, rear panel 5) to input stereo signals. If you connect signals only to the 13L (MONO) jack or 15L (MONO) jack, the same signal will be sent t the o M1­4 and ST buses. HIGH A GAIN control +15 ­15 This control is used to adjust input sensitivity. The adjustable range is +10 dB to ­34 dB. HI-MID B PEAK indicator +15 ­15 LO-MID 4 +15 This indicator lights up when the level of signals that have been processed by the EQ reaches 3 dB below the clipping level. ­15 C High pass filter switch This high pass filter is used to cut the frequency range below 80 Hz with a slope of 12 dB/ oct. LOW ­15 +15 EQ M1 5 D EQ controls (HIGH/HI-MID/LO-MID/LOW) This 4-band equalizer provides ±15 dB of cut and boost over each range, with the center frequencies and types shown in the following table.

M6 PRE 0 10 M7 F M1­M4 mix level controls 9 These controls are used to route the pre fader signals from the stereo input channel to MIX buses 1­4. When stereo signals are input, the L channel signal will be sent to MIX buses 1, 3, and the R channel signal will be sent to MIX buses 2 and 4. Note: When you press down the M1­M4 switches to the FIX position in the Variable/ Fix select section (see page 6), the output level of signals sent to the MIX buses will be fixed and the corresponding M1­M4 mix level controls will be disabled. 8 0 10 M8 PRE 0 10 M9 0 10 M10 PRE 0 10 BAL 0 L R G ON switches (M1­M4) These switches are used to turn on and off the signals routed from the stereo input channel to MIX buses 1­4. Note: When these switches are set to off, no signals are sent from the stereo input channel to the corresponding MIX buses regardless of the setting of the switches in the Variable/Fix select section (see page 6). A ST B ON PFL C 10 5 0 H M5­M10 mix level controls D These control knobs route the stereo input channel signals to MIX buses 5­10. Stereo input signals are mixed into a monaural signal and sent to MIX buses 5­10. Use the PRE switches 9 to select pre- or post-fader. 5 10 20 30 40 50 60 GA32/12, GA24/12--Owner's Manual Stereo input channels 5 I PRE (Pre-fader) switches These switches are used to select pre- or post-fader for signals sent from the stereo input channel to MIX buses 5­10. Each switch is effective for one pair of MIX buses:5/6, 7/8, or 9/10. When you turn these switches on, the pre-fader signals are sent to the corresponding MIX bus pair. J BAL (Balance) control This control is used to adjust the left and right balance of signals sent from the stereo input channel to the ST bus. K ST (Stereo) switch When you turn this switch on, the stereo input channel signals will be sent to the ST bus. Matrix 1­2 signals are output in monaural via the MATRIX OUT 1­2 jacks (rear panel K). A M1­M4 level controls These control knobs enable you to adjust the input level of MIX bus 1­4 post-fader signals. M1 M1 0 0 M2 M2 B L/R controls These control knobs enable you to adjust the input level of the ST bus post-fader signals for the L channel and R channel independently. 1 0 0 M3 M3 0 0 M4 M4 0 0 C LEVEL control D ON switch L L This control knob enables you to adjust the output level of Matrix 1­2 signals. 2 This switch turns on and off Matrixes 1­2. When you turn this switch off, the corresponding matrix signal is not output from the MATRIX OUT jack. The signal is not sent to the AFL bus, either. 0 0 R R 0 0 LEVEL LEVEL 3 0 10 0 10 4 ON 1 AFL ON 2 AFL MATRIX E AFL (After-fader Listen) switch 5 When you turn this switch on, the matrix 1­2 post-fader signals are sent to the AFL bus. You can monitor the signals via the C-R MONITOR OUT jacks or PHONES jack. However, this switch will be disabled if the ON switch (4) is turned off.

A Monitor source select switch PFL/AFL TAPE IN PFL LEVEL 1 2 3 This switch enables you to select the type of signal to monitor via the C-R MONITOR OUT jacks and the PHONES jack. s When the switch is set to PFL/AFL ( ) 0 10 ON 4 5 10 C-R MONI LEVEL 0 You will monitor PFL signals (signals routed from input channels/AUX returns to the PFL bus) or AFL signals (signals routed from MIX buses 1­10/ST buses/MATRIX 1­2 to the AFL bus). If any one of the PFL switches for the input channels/AUX returns is turned on, the PFL indicator 2 will light up. In this case, the PFL bus signals (not the AFL bus signals) are routed to the C-R MONITOR OUT jacks and PHONES jack. If all the PFL switches are turned off, the AFL bus signals are sent to the C-R MONITOR OUT jacks and PHONES jack. Note: If you turn on any one of the PFL switches for the input channels/AUX returns while monitoring the AFL bus signal, the switching circuit will switch the signal to the PFL bus signal. s When the switch is set to TAPE IN ( ) You can monitor the signals input from the TAPE IN jacks (see page 18, rear panel N). B PFL (Pre-fader Listen) indicator This indicator lights up when any one of the PFL switches for the input channels/AUX returns is turned on, indicating that the PFL bus signal is currently being monitored. 6 C LEVEL control This control enables you to adjust the level of signals output from the C-R MONITOR OUT jacks. This setting does not affect the signal level at the PHONES jack. D ON switch PHONES This switch turns on and off the monitoring signals output from the C-R MONITOR OUT jacks.
