[Note: Always reset a channel’s
input Gain (or external devices’
output level) after altering the
amount of mixer equalization cut or
boost applied.]
The key to successful equalization
is to avoid excess. Too much
equalization on the input channels
will result in a mix that is smeared
together with nothing specifically
defined. During rehearsals,
experiment with the equalizer
controls on various instruments,
vocals and combinations of these
mixed together to become familiar
with various equalizer settings.
(6) PAD
This switch attenuates the input
signal by -20dB. When connecting
a line level device to channels, or if
the mic input is distorted, set this
switch to the position of -20dB.
(7) LINE INPUT
The Line input is designed to
accept balanced or unbalanced
line-level signals such as those from keyboards, drum machines,
or samplers. There is enough gain available on the line input to
accept even lower level signals, such as those from an
unbalanced microphone or guitar output. If a balanced signal is to
be connected to the line input, then a 1/4" TRS (stereo) phone
plug should be wired for: Tip = positive (+), Ring = negative (-),
Sleeve = ground.
(Note: Only either the Mic or the Line input of a given channel
should be connected at one time.)
(8) MIC INPUT
The Mic input is an electronically balanced XLR type designed to
accept signals from any balanced or unbalanced low impedance
(Low Z) microphone. The XLR jack is configured for: Pin1 =
ground, Pin2 = positive (+), Pin3 = negative (-).

(9) L AND R CHANNEL GRAPHIC EQUALIZER
The 7-band channel graphic equalizer allows you to adjust the
frequency response of the L and R Channel bus signal, providing
a maximum of ±12dB of cut and boost for each frequency band
from the flat position. When in BRIDGE MODE, the L-Channel EQ
controls the output.
(10) L AND R AMP PROTECT LED
These LEDs will indicate the operation of the protection circuits in
the POWER AMP (L and R) section. Shut off unit if this lights
during use, and check output connections. Do not operate the unit
until this LED is off. If the condition persists, have the unit
serviced by qualified personnel.
(Note: This LED will flash when the unit is powered on. This is
normal.)
