Channel controls 9 6 AUX controls (1-6) These knobs adjust the level at which the input channel signal is sent to the AUX buses 1-6. AUX controls 1 and 2 are fixed at pre-fader, and AUX controls 3-6 can be switched between pre/post fader using the PRE switch (7). When a knob is in the "√" position, the level is "nominal." 7 PRE switches These switches select whether the pre or post fader signal will be sent to AUX buses 3-6. This setting is switched in pairs: AUX 3/4 and 5/6. When the switch is pressed in, the pre-fader signal will be sent to the corresponding pair of AUX buses. When the switch is in the upward position, the post-fader signal will be sent. 8 BAL (balance) control This adjusts the left/right balance at which the signal of the stereo input channel will be sent to the ST (stereo) bus, GROUP bus 1/2, and GROUP bus 3/4. 9 ON switch This switches the input channel on/off. When this switch is turned off, the signal of the input channel will not be sent to the ST bus, GROUP buses, or AUX buses. However even if this switch is off, you can use the PFL switch (B) to monitor the signal from the C-R OUT jacks or the PHONES jack. 0 Group select switches These switches send the signal of the input channel to GROUP buses 1-4. When the 1-2 switch is on (pressed in) the signal will be sent to GROUP bus 1/2. When the 3-4 switch is on, the signal will be sent to GROUP bus 3/4. A ST (stereo) switch This switch sends the signal of the input channel to the ST bus. When this switch is on, the signal will be sent to the ST bus. B PFL (pre-fader listen) switch This switch sends the pre-fader signal to the PFL/ AFL bus, allowing you to monitor it through headphones or monitor speakers. When this switch is on, the pre-fader signal of the input channel can be heard from the C-R OUT jacks and the PHONES jack, even if the ON switch (9) is off. C Channel fader This fader adjusts the input level of the stereo input channel. The position of the channel fader will affect the level of the signal that is output from the ST bus, GROUP buses 1-4, and AUX buses 1-6 (except when the PRE switch is on for AUX buses 3-6). *1,*3 (MONO) INPUT A *2,*4 *1,*3 INPUT B *2,*4 A HA HPF B 3 Stage EQ 80 HA HPF 3 Stage EQ 80 No. GF12/12 GF16/12 GF24/12 *1 9L 13L 21L *2 10R 14R 22R *3 11L 15L 23L *4 12R 16R 24R GAIN LOW MID HIGH PEAK ST ON BAL 1-2 GROUP AUX PFL/AFL ST 1234 123456 LR LR 3-4 AUX 1 AUX 2 PRE AUX 3 AUX 4 PRE AUX 5 AUX 6 PFL Stereo input channel signal flow -Owner's Manual
