AMP ROUTING switch will select between two internally routed configurations: OUT postion: AMP1-LEFT, AMP2-RIGHT, AMP3-MONITOR1, AMP4-MONITOR2 IN position: 1 amp each, for Monitors 1 thru 4. Speaker output levels are adjusted from the Left/Right faders or Monitor 1-4 controls. The front panel GRAPHIC EQs function with the amps, depending on the front panel EQ1 and EQ2 switch settings. [. . . ] This feature saves having to reset your faders and monitor sends. CHANNEL PFL SWITCH This switch allows the operator to listen to a channel (pre fader listen) in the headphone mix to set tone and gain levels as well as see the channel at the LED meter output (#29). 17. MIC PHANTOM POWER SWITCH / RED LED This switch provides +48v power for condenser mics such as Carvin's CM90E in groups of 8 channels. This leaves the remaining MIC inputs for sources that don't require phantom power. The LINE inputs are unaffected by +48v power. 7. MID SWEEP This control allows you to select which frequency (from 100Hz to 5kHz) that the MID control will boost or cut. Instruments and singers have various tonal qualities. By adjusting the MID FREQ, you can select the exact frequency that will best complement these various inputs. 700Hz is a recommended setting for the MID FREQ control for guitar and vocals. 2 E PK 456 7 3 8 2 9 1 0 10 3 6 9 OFF 3 6 9 B CHOR ER E 4. GAIN The GAIN controls the input level for the channel. If the GAIN is set too high, the PEAK LED will flash and distortion may occur. Decrease the amount of GAIN until the PEAK LED does not flash. It is important that the gain control should be kept next to the PEAK LED flash point to maintain the lowest noise of the channel. You can use the channel PFL switch to monitor the channel input level and use the meters to adjust the GAIN control to 0dB. This will give you a good reference point where the GAIN control should be set. 6 -15 +15 MON 5 LOW LOW -15 +15 5 LOW -15 +15 MON 5 LOW -15 +15 MON 5 LOW -15 +15 MON 5 LOW -15 +15 MON 5 LOW -15 +15 MON 5 LOW -15 +15 MON 5 LOW MON MON MON MON MON MON 5 18. CHANNEL ASSIGNMENT SWITCHES The internal 24-BIT stereo processors receive signals from These switches assign the channels' signal to the Master L/R the EFF 1 / EFF 2 channel controls. If the adjacent PK (peak) faders, or to the SUB-GROUP faders 1 & 2, 3 & 4 for subLED flashes, reduce the level from the channel EFF 1 / EFF mixing in stereo pairs. For mono, PAN fully to the left and 2 send controls. A "solid" PK LED will show EFFECTS 1 or 2 assign a channel to Sub-Group fader 1 or 3 only. PAN fully have been muted either by the MUTE switches (#44) or by to the right and assign a channel to Sub-Group fader 2 or the optional FS22 footswitch (#38). Likewise assigning the L/R switches sends the channel adjust the volume level of the selected effects. Remember each directly to the main L or R faders. [. . . ] The "half" insert connection creates a send signal without breaking the channels signal path. The insert in this mode is no longer used as an insert but becomes what is called an DIRECT out. 1 PIN 2 (+) PIN 3 (­) MIC MIC Pre-Amp GAIN INSERT JACK INSERT INSERT GAIN 456 3 7 2 8 1 9 0 10 HI -0+ 3 3 6 6 9 12 MID 6 9 3 12 -0+ 3 6 9 INSERT JACK GAIN 456 3 7 2 8 1 9 0 10 HI -0+ 3 3 6 6 9 9 12 MID 6 3 12 -0+ 3 6 MONO PLUG STEREO PLUG 9 12 12 LOW - 0 + 3 3 6 6 9 12 12 9 9 9 12 12 LOW - 0 + 3 3 6 6 9 12 12 9 TO RECORDER SEND RETURN TO EFFECTS MULTI-TRACK RECORDING ADJUSTING THE 9-BAND EQ When the 9 band graphic EQ sliders are in their "center" position, they do not affect the audio signal. When the EQ sliders are raised or lowered from this position, they boost or cut respectively a narrow band of frequencies. To reduce feedback in the low frequency range, try lowering one of the 63, 125 or 250 Hz sliders. [. . . ]
