7.Position your main PA speakers at the front of the stage, pointing directly out at the audience and position your monitor speakers on the stage floor, in front of the mic stands, pointing up at the backs of the mics (remember to use cardioid or
8.During a sound check with the band playing or other sources feeding the mixer inputs, make the following control adjustments:
a)Set the channel LOW, MID & HIGH EQ controls and PAN or BAL controls at center. Now set the channel GAIN, MON and EFX controls to OFF, the chan- nel fader all the way down, and the GRAPHIC EQ sliders at center position.
b)Set the MAIN faders at 0 dB, turn the MONITOR MASTER control up to approx. 8, the MAIN EFX master to around 7 and MONITOR EFX master to 5.
c)With the level faders still off, turn up the channel GAIN controls slowly until the CLIP LED’s down beside the level faders begin to flash slightly. Now bring up the channel level faders slowly until each channel can be heard at the desired volume level through the main PA speakers.
d)Turn up the channel MON controls until the performers can hear themselves at adequate volume levels without feedback.
e)Turn up the EFX controls on those channels requiring reverb. Usually this would be the lead and harmony vocal channels. Reverb may be used on other channels or on recorded music, but at lower levels.
f)Set the EFX SELECT control to establish the basic type of reverb, delay or what- ever you prefer, then adjust the MODIFY control to establish the final sound.
9.Feedback during a performance is usually caused by one of the monitors. The main PA is less likely to feed back because the mics are so far away from the main PA speakers. Therefore, if one of the monitors and a mic are feeding back, try the following procedures:
a)Turn the MONITOR master down until the feedback stops.
b)Go to EQ 2 and pull down one or two (but not more) of the EQ sliders in the frequency range where the sound seems to be occurring.
c)Now turn the MONITOR master back up. If the feedback recurs, push the EQ slider/s back up to center position and try pulling down one or two others.
d)In the rare case of main system feedback, follow the above type of procedure, but using the MAIN master and the built in GRAPHIC EQ.
Note B: The following notes apply to the system with the EQ/AMP ASSIGN button up in the stereo L & R position.
If you are employing a separate power amplifier for the monitor speakers, connect the main speakers to the AMP 1 and AMP 2 SPEAKER OUTPUTS as in 6. above (also see SPEAKER CONNECTIONS). Now run a shielded patch cord from the MONITOR OUT jack to the input of the monitor power amp.
If you are employing a graphic equalizer for the monitors (a good idea - remember there is no
