[. . . ] When the switch is in the downward section ( ), the input signal of the INPUT B jack is selected (0 of the connector section). ­15 LOW ­15 +15 AUX PRE 0 10 1 2 0 10 2 GAIN control This adjusts the input sensitivity. The range of levels that can be accommodated is +10 dB to ­34 dB. 3 PRE 0 10 6 4 3 High pass filter switch 0 10 7 5 PRE 0 10 This is an on/off switch for the high pass filter that cuts the frequency range below 80 Hz at a slope of 12 dB/octave. The high pass filter is on when the switch is pressed in. 6 0 10 4 PEAK indicator BAL 8 L ODD R EVEN 9 ON 10 This is an indicator that detects post-EQ clipping. It will light 3 dB before clipping, indicating that the signal is near the clipping level. If this LED lights, lower the GAIN control (2). 5 EQ controls (HIGH/MID/LOW) 1­2 0 A 5 0 3­4 This is a three-band equalizer that boosts/cuts each frequency band over a ±15 dB range.

AUX controls 1 and 2 are fixed at pre-fader, and AUX controls 3­6 can be switched between pre/post fader using the PRE switch (7). When a knob is in the "" position, the level is "nominal. " 0 Group select switches These switches send the signal of the input channel to GROUP buses 1­4. When the 1­2 switch is on (pressed in) the signal will be sent to GROUP bus 1/2. When the 3­4 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. 7 PRE switches These switches select whether the pre or post fader signal will be sent to AUX buses 3­6. 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. 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. 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. 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 1­4, and AUX buses 1­6 (except when the PRE switch is on for AUX buses 3­6). 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.

Nominal level is the same as the INPUT A jacks (6). On the stereo input channels, you can make connections both to the INPUT A jacks (6) and the INPUT B jacks (0), and use the A/B switch (page 8, 1 in the stereo input channel section) to select whether INPUT jack A or B will be used.
