Channel control section
In this section, you can adjust equalization (fre-
quency response), volume level, effect and AUX
output levels for the input signal of each channel.
1
26 dB pad switch
This switch attenuates the input signal by 26 dB.
Attenuation is on when the switch is pressed
inward.
2
GAIN control
Use this knob to adjust the sensitivity according
to the input signal level, so that the input level is
appropriate.
For the best balance of S/N ratio and dynamic
range, adjust this knob so that the peak indicator
0
lights occasionally.
* When the knob is at the “ ” position, the input
sensitivity will be +4 dB.
3
(High pass filter) switch
This is an on/off switch for the high-pass filter.
The high-pass filter is on when the switch is
pressed inward, and the frequency region below
80 Hz will be attenuated at 18 dB/octave.
4
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.
When the HIGH and LOW knobs are in the “
▼
”
position, the high and low ranges will have a flat
response. Turning a knob toward the right will
boost the corresponding frequency range, and
turning it toward the left will cut it.
For the mid range, use the upper MID knob to
specify the center frequency of the range, and use
the lower knob to set the amount of boost or cut
that will occur. The frequency response is flat
when the lower knob is set to the “
▼
” position.
Turning the lower knob toward the right will
boost the corresponding frequency range, and
turning the knob 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: 10kHz, ±15 dB, shelving type
MID: 250Hz–5kHz, ±15 dB, peaking type
LOW: 100Hz, ±15 dB, shelving type
