FRONT PANEL CONTROLS AND FEATURES
Modules with built-in controls are provided in the following six types.

GAIN CONTROL
THRESHOLD
(M-61)
OUTPUT GAIN
(T-02)
NOMINAL POSITION
MARK
LOW-CUT FILTER
CONTROL
330Hz, 6dB/oct
(max. attenuation)
MUTE LEVEL
(U-12)
INPUT GAIN
(T-02)
This adjusts gam. Turn clockwise (CW) to
increase and counter-clockwise (CCW) to
reduce gam
Set the gam as low as possible, thereby,
noise can be reduced, and the maximum
permissible input level is raised.
This adjusts threshold level of compressor.
Turn clockwise (CW) to reduce threshold
level (to activate the compressor with low-
er input signal level).
This adjusts gam of the line output. Turn
clockwise (CW) to increase and counterc-
lockwise (CCW) to reduce gam regardless
of setting position of the input gam adjust
knob.
The left figure shows nominal set-
ting of controls.
This provides flat characteristics at full CW
position and attenuation in low frequency
by turning CCW. Adjust it to obtain proper
tone quality. With low-cut, tone becomes
clear.
This adjusts mute level. Turn clockwise
(CW) to increase mute level (to be muted
excessively) and counterclockwise (CCW)
to reduce mute level.
This adjusts input gam from AUX. Turn
clockwise (CW) to increase gam and coun-
terclockwise (CCW) to reduce.

HIGH-CUT FILTER
CONTROL
4.2kHz, 6dB/oct
(max. attenuation)
SENSITIVITY
(M-51)
This provides flat characteristics at full CW
position and attenuation in high frequency
by turning CCW. Adjust it to obtain proper
tone quality. With high-cut, tone becomes
soft.
This adjusts sensitivity for voice gate.Turn
clockwise (CW) to increase sensitivity (to
open the gate at full CW position regard-
less of any input level) and counterclock-
wise (CCW) to reduce sensitivity.
