FACILITIES AND FEATURES
BASS: Slide control with mechanical detent for flat
-16 dB to +16 dB at 20 Hz
TREBLE: Slide control with mechanical detent for
flat -16 dB to +16 dB at 20,000 Hz
LOUDNESS: Pushbutton ... for loudness compen-
sated or flat response
BALANCE: Natural balance at center position, attenu-
ation of left or right channel by rotating control.
VOLUME: Precision "tracked" at all listening levels.
(0 to -65 dB.) Does not change stereo balance as
loudness is changed. The AC power ON/OFF switch
is coupled with this control.
INPUT: Six positions - TAPE 1, TAPE 2, AM, FM,
PHONO 1, and PHONO 2.
MODE: Pushbutton - Left channel only to both speak-
ers. Right channel only to both speakers, Stereo Re-
verse, Stereo, Mono, L+R, L+R to right speaker only,
and L+R to left speaker only.
TAPE MONITOR: Two pushbutton switches. Either of
two tape recorders can be monitored by selecting
the TAPE MON. 1 pushbutton or TAPE MON. 2 push-
button. They are mechanically interlocked to accept
only one pushbutton at the IN position at one time.
SPEAKER: Main-Switch the MAIN loudspeaker sys-
tem ON or OFF without affecting the performance of
REMOTE speakers.
Remote 1 - Switch one REMOTE loudspeaker
system ON or OFF without affecting the performance
of MAIN speakers.
Remote 2 - Switch a second REMOTE loud-
speaker system ON or OFF without affecting the per-
formance of MAIN speakers.
HEADPHONE JACK: For listening with low impedance
dynamic stereo headphones.
TRANSISTOR COMPLEMENT: 53 silicon field effect
or bipolar transistors, 39 diodes, 3 integrated cir-
cuits, 4 thyristors.
