LOW
FILTER
SWITCH
The low frequency filter can be used
to
reduce
turntable
rumble and low frequency noise. It
will also, however, slightly
attenuate
program
material, and should
therefore
be used judiciously.
The
"out"
position switches
the
filter
out
of
the
circuits.
Hi FILTER SWITCH
AM radio reception is sometimes subject
to
a
high pitched interference
"whistle"
from a
nearby
adjacent
AM channel.
The
high frequency filter
will suppress this interference,
the
"scratchy"
noise from phonograph records,
and
tape
"hiss."
The
filter will also, however, slightly
attenuate
high frequency program material.
The
"out"
posi-
tion
switches
the
filter
out
of
the
circuits.
MUTING SWITCH AND LEVEL CONTROL
When tuning
to
FM broadcasts with
the
MUTING
switch in its
"in"
position,
the
muting
circuit
will
eliminate interstation noise.
The
mut
ing threshold
can be varied by
rotation
of
the
MUTING LEVEL
control on
the
rear panel.
To
prevent muting very
weak
stations
along with
the
noise ,
the
muting
function may be
turned
off
by releasing
the
MUTI N-
G pushswitch
to
"out"
position,
thus
switching
all muting
out
of
the
FM circuits.

SELECTOR SWITCH
The
selector switch selects
the
program source for
listening or recording. With
tape
recorder's
outputs
connected
to
the
rear panel TAPE RECORDER
PLAY (1, 2) jacks, you can select
tape
Iisten-
ing by rotating
the
selector switch
to
the
"
TAPE"
position (with
the
MONITOR (TAPEI
SOURCE) pushswitch
"out".
The MONITOR (1/2)
pushswitch
then
selects between
tape
units
plugged
into
rear panel PLAY 1 or PLAY 2 jacks.
BALANCE CONTROL
This control simultaneously alters
the
output
level
of
both
channels. As
the
knob
is
turned
away
from
the
normal 12
o'clock
position, it decreases
the
level in
one
channel, while it increases
the
level in
the
other
channel. (Because
the
balance
control
knob has been
set
for
precise electrical
balance when
the
po
inter
is
at
the
indicator
dot
at
the
12
o'clock
position,
there
may be slightly
greater mechanical
rotation
off
center
in one
direction
than
in
the
other.)
VOLUME CONTROL
This dual
control
maintains stereo balance at all
normal settings. It
controls
the
level of
both
output
channels simu ltaneously
and
has no
effect
on
the
recording
outputs.
