SWITCHES AND CONTROLS
Power Indicator

Switch, and remains lit until you turn off the
switch.
Power/Speakers Switch
Controls both the power supply and selection of
speaker systems.
|
POWER
OFF:
Cuts off power supply for the
amplifier.
A: Turns on power
supply and energizes the
speaker systems connected toSYSTEM-A speaker
terminals on the rear.

Because of the built-in amplifier/speaker protec-
tion circuit, sound will come out with a delay of
a few seconds.
B:
Energizes
speaker
systems
connected
to
SYSTEM-B speaker terminals.
A+B:
Energizes both A and B pairs of speaker
systems.
SPKR OFF: Cuts off the sound from all speaker
systems to permit private listening with head-
phones connected to the Headphone Jack.
Headphone Jack
Plug stereo headphones into this jack for private
listening or monitoring, but be sure to turn the
Power/Speakers Switch to SPKR OFF first unless
someone is listening to the sound from speaker
systems in another room. The jack will accept any
standard stereo phone plug, but for best tone
quality, we recommend
a dynamic type such as
the Sansui SS-20 or SS-10.
Filters
,
Low:
Push down
to IN to eliminate
low-fre-
quency noise such as the rumbling of your turn-
table motor.
If no such noise is present, be sure
to keep it off.
High:
Push down to IN to eliminate high-fre-
quency noise such as the surface noise from a
worn
record or as the fluorescent
lamp
noise
mixed in radio broadcasts.
Tone Controls
Let you tailor the tone quality of reproduced sound
to your taste by adjusting the amplifier's frequency
response curve.
The Bass Control is for adjust-
ing the loudness of bass notes as may be produced
by a bass, and the Treble one for adjusting that
of treble notes as may be produced by cymbals. —
Muting Switch
Reduces the sound volume by 20dB at once with-
out the use of the Volume Control.
Most con-
venient to lower the sound volume temporarily
when the telephone rings, to avoid the noise of
the pickup stylus descending on a record, etc.
