FACILITIES AND FEATURES
VOLUME CONTROL: 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.
BALANCE CONTROL: Natural balance at center position,
attenuation of left or right channel by rotating control.
LOUDNESS: Loudness compensated or f a t response—
Loudness position boosts low frequencies for low level
listening. Operates as a function of volume control position.
Full compensation is obtained at lower volume levels and
flat response is obtained at full volume.
SELECTIVITY: Increases the ability of the tuner to separate
a weak (distant) station from a strong (local) station on
adjacent channels.
MUTING: Suppresses the background noise and hiss nor-
mally heard between FM stations.
TAPE MONITOR: Pushbutton; compares recorded tape with
program source while recording.
MODE: Selects either stereo or mono operation.
PHASE CONTROL: Electronically reverses phase in the left
channel to correct "out of phase" program sources.
MUTING ADJUST: Modifies the noise rejection threshold
on FM
DIAL SCALE INTENSITY: Modifies the brightness of the
illumination of the front panel
