• FORNT PANEL CONTROLS AND FEATURES
Modules with built-in controls are provided in the following five
types.
GAIN CONTROL
SENSITIVITY
CONTROL (L-41S)
NOMINAL POSITION
MARK
This adjusts gain. Turn clockwise (CW)
to increase and counterclockwise (CCW)
to reduce gain.
Set the gain as low as possible, thereby,
noise can be reduced, and the maximum
permissible input level is raised.
This adjusts sensitivity for muting other
modules having MUTE function. Turn
CW to raise and CCW to lower sensitivity.
Setting position should depend on the
equipment connected with L-41S.
The left figure shows nominal
setting of controls.
LOW-CUT FILTER
CONTROL
330Hz, 6dB/oct
(max. attenuation)
MUTE DELAY
CONTROL (I-01S)
HIGH-CUT FILTER
CONTROL
4.2kHz, 6dB/oct
(max. attenuation)
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 delay time which is
the duration from signal input to its
output. Turn CW to shorten and CCW
to lengthen the time.
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.
