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. [. . . ] MONITOR 1 THRU 4 SEND CONTROLS The channel MONITOR controls allow you to create four independent monitor mixes. The MONITOR signals (pre-EQ, pre fader) are routed to the master MON 1, 2, 3 and 4 controls (#21) respectively before going to the output connectors (#36). EFF 1 & EFF 2 SEND CONTROLS The EFF 1 or EFF 2 control sends signal (post EQ, post fader) from the channel to the EFFECTS 1 or EFFECTS 2 internal processors (#18) and to the EFF 1 or EFF 2 jacks (#33). 12. If the PEAK LED flashes, the channel needs a reduction with the GAIN control (#4)to prevent distortion. A "solid" lit PEAK LED indicates that the channel has been MUTED. 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. MID SWEEP This control allows you to select which frequency (from 100Hz to 5kHz) that the MID control will boost or cut. 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. If the GAIN is set too high, the PEAK LED will flash and distortion may occur. 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. 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. CHANNEL FADER The CHANNEL FADER adjusts the output level of the channel. The red PK LED will indicate when the effects signal from the channel is distorting. [. . . ] The signal coming from the microphone preamplifier will be forced to go through the external equipment before it can continue back through the channel, reentering before the channel EQ controls. Most external equipment is not set up for the TRS plug directly so an adapter cable such as the Carvin AP1 or PP10 is required. The two mono 1/4" TS jacks at the opposite end are the send and return cables. If both an INSERT and a DIRECT out is required, "Y" the SEND cable.
