the mixer to the main amplifier using standard cables with 1/4"
TRS connectors. We recommend using balanced cables if the dis-

GROUND LIFT SWITCH
The GROUND LIFT SWITCH is used to reduce background noise &
hum when using multiple outlets to power audio equipment. The
switch should be in the position that provides the least amount of
noise or hum. If noise remains at the same level in both positions,
the GROUND LIFT SWITCH should be kept in the GND position
NOTE: MAKE SURE THE MIXER AND/OR AMPLIFIER IS OFF BEFORE SWITCHING THE GROUND LIFT
SWITCH TO PREVENT A TRANSIENT POP THAT MAY DAMAGE YOUR SYSTEM.
PHONO/LINE INPUTS:
Located on the rear panel are 2 PHONO (PH) /LINE (LN) convertible
RCA inputs, & 5 LINE RCA INPUTS. The convertible RCA inputs for
CH 2 & CH 3 allow PH and LN level equipment to be connected to
the mixer.
