CONTROL DESCRIPTION
INPUT CHANNEL
8 GAIN
This rotary knob adjusts the mono channel signal
level. If it is set too high, the signal will distort and lose
definition. When it is set too low, you will not be able to
get enough signal level for output. Proper gain setting
allows mixer to work at the best operating level.
The inner-ring for microphone input indicates level
from +10dB to +60dB while the outer-ring for line input
indicates level from -10dB to +40dB.
9 EQUALIZER
Equalizers are designed to suit different room
acoustics, feedback control and thus improve the live
sound. Always begin with the “ 0” position and avoid
excessively cutting/boosting peculiar frequency, which
will limit the systems dynamic range or sometimes
even increase the possibility of the unpleasant feedback
sound.
The level control for each band provides 15dB of
boost or cut at its frequency. Position the knob at the
“ 0” position when you do not intend to make any
adjustment.

HIGH (12KHz)
Turn the knob clockwise to add crispness to
cymbals, vocals and electronic instruments. Turn it
counter-clockwise to reduce sibilance or hiss.
LOW (80Hz)
Boost at this frequency could add extra punch to
guitars, drums and keyboards by turning clockwise. Cut
it to reduce stage rumble, hum or to improve a mushy
sound.
10 LOW CUT
Push down the LOW CUT button adds the 18dB
per octave 75Hz low cut filter in the signal path, which
can be used on live vocals to reduce stage rumble or
“ popping” from microphones. It can also cut off low
frequency hum.
11 PAN (CH-1) / BAL (CH2/3 & 4/5)
PAN, short for panoramic potentiometer, is a control
that divides a signal between two channels in an
adjustable ratio. By doing so, PAN controls the location
of a sonic image between the left and the right channel
of the MAIN out. When it is turned fully to the left (L),
the signal will be routed to the left channel only. Turn it
fully to the right (R) you would route signal to the right
channel only. Set it in the center, both left and right
channels will have the same level from the input
channel.
BAL control on input channel 2/3 & 4/5 allows you
to balance the left and right input source between the
stereo sound images.
12 PEAK INDICATOR
Right before the input channel signal becomes
distorted and loses definition, the PEAK LED will come
on. The level of the GAIN control should therefore be
reduced when it remains on or blinks constantly.
13 CHANNEL LEVEL CONTROL
This rotary level control determines the final output
level of the related input channel.
