1. Connect the AC power cord to a 120 Volt AC grounded power outlet (220 to 240
2. Turn the MAIN and MONITOR MASTER controls to 0 for now, then switch
3. You can connect low-impedance microphones to the 3-pin XLR type MIC inputs.
4. Connect high-impedance mics or mono line-level signal sources (i.e.
5. Connect stereo sources (tape deck, CD player, stereo keyboard instrument, etc.)

etc.), to the 1/4" BAL LINE IN jacks on channels 1 to 6. Do not connect
more than one signal source to any of these channels, that includes stereo
outputs (if you try to connect a stereo source to a mono channel using a Y
adapter, you may get distortion).

summed into mono. Once again, connect only one signal source per channel,
and use shielded patch cords for all pre-amp connections.
connect speakers, they cannot handle the high current and will waste power by
heating up), connect one or two 8-Ohm main PA speakers to the AMP A
SPEAKER outputs on the back panel. If you have 4-Ohm speakers, you may
connect only one. Connect 1 to 4 8-Ohm monitors, or up to two 4-Ohm
monitors to the AMP B SPEAKER outputs.
a. If you are employing a separate power amplifier for the monitor speakers,
run a shielded patch cord from the MONITOR LINE OUT jack to the input
of the monitor power amp. If you are employing a separate graphic equalizer
for the monitors run a shielded patch cord from the MONITOR LINE OUT
jack to the input of the EQ. Then, another one from the EQ's output to the
input of the monitor power amp.

mic stands, pointing up at the backs of the mics. (Remember to use cardioid or
uni-directional mics to reduce the threat of monitor feedback).
inputs, make the following control adjustments:
i. Set the channel LOW, MID, and HIGH EQ controls at center. Now, set
the channel GAIN, MON, and EFX controls at 0 and the GRAPHIC EQ
sliders at center position.
ii. Turn up the MAIN and MONITOR MASTER controls to approximately 8, the
MAIN EFX master to around 7 and MONITOR EFX master to 5.
iii. Turn up the channel MON controls until the performers can hear themselves
at adequate volume levels without feedback.
iv. Turn up the channel GAIN controls slowly until each channel can be heard
at the desired volume level through the main PA speakers.
v. Turn up the EFX controls on those channels requiring effects. Usually this
would be the lead and harmony vocal channels. Reverb may be used on
other channels or on recorded music, but at low levels.
