■ Channel section
In this section, you can adjust equalization (fre-
quency response), volume level, effect and moni-
tor output levels for the input signal of each
channel.
1
Equalizer controls (HIGH, MID, LOW)
This is a 3-band equalizer that adjusts the high
frequency range, mid frequency range, and low
frequency range of each channel. Response is flat
when the knobs are in the ▼ position. Rotating it
toward the right will boost the corresponding fre-
quency band, and rotating it toward the left will
cut it.
The base frequency (or center frequency), range
of boost or cut, and equalizer type of each band
are as follows.
HIGH: 12 kHz ± 15 dB shelving type
MID: 2.5 kHz ± 15 dB peaking type
LOW: 80 Hz ± 15 dB shelving type
2
Monitor controls (MONI)
For each channel, this controls the amount of sig-
nal that is sent to the MONITOR bus.
The signal of the MONITOR bus is sent to the
speakers connected to the POWER AMP 2 A/B
jacks (only if the power amp select switch is in the
MAIN+MONITOR position) and to the MONI-
TOR jacks (input/output panel 6 ).
3
Effect control (EFFECT)
For each channel, this controls the amount of sig-
nal that is sent to the EFFECT bus.
The signal of the EFFECT bus passes through the
EFFECT section and the built-in effect, and is
sent to the external effect device connected to the
EFFECT OUT jacks (input/output panel 3 ).
4 Level control (LEVEL)
This adjusts the output level for each channel.
5
Pad switch (PAD) (1~4 only)
This switch attenuates the input signal by 30 dB.
When connecting a line level device to channels
1~4, or if the mic input is distorted, turn this
switch on (the pressed-in position).

Note: The signal is sent to the MONITOR bus
from a location before the level control ( 4 ) of
each channel. This means that it will not be af-
fected by the setting of the LEVEL control.
Note: The signal is sent to the EFFECT bus
from a location after the level control ( 4 ) of
each channel. This means that the amount of
signal that is sent to the EFFECT bus will be af-
fected not only by the setting of the effect con-
trol, but also by the setting of the level control.
