VOLUME
CONTROL
AND MUTING SWITCH
The VOLUME
control is calibrated in dB units for
direct readout.
By adjusting it in combination with the MUTING
switch, it is possible to adjust the attenuation more
finely across a very wide range.
When
the MUTING
switch is set to FLAT
AMP
BYPASS
or NORMAL,
the volume will be attenu-
ated 20dB more than the position indicated by the
VOLUME
control. You will achieve good results if
the FLAT
AMP
BYPASS
and NORMAL
positions
are
selected
in accordance
with
the applications
described below.
Using the
FLAT AMP BYPASS position
You
will not be able to adjust the volume. How-
ever, the sound
will bypass the flat amplifier and
tone control circuits for a clearer sound quality.
Set the switch to this position when you do not
want to adjust the sound quality and when a high
volume
output
is not required.
Then
adjust the
sound with the VOLUME
control.
Using the
NORMAL position
e There will be no need to adjust the VOLUME
control
every
time
you change over a tape or
record if you set the switch to this position for
reducing the volume temporarily during play.
e You will not be able to finely adjust the volume
if the VOLUME
control is near the ~ position
when listening to a program at a low sound level
at night,
for example.
In such
cases,
set the
MUTING
switch to NORMAL
and you will then
be able to adjust the sound with the VOLUME
control to more fine steps.
NOTE:
Always
turn
the
VOLUME
control
right
down
when
returning the MUTING
switch to OFF during a perform-
ance
when
the
sound
is set
to a high
level
with
the
VOLUME control.
