AM/FM
Tuner-Amplifier
A new (in
1981) budget tuner amplifier. Computer Analyzed Tuning (CAT) system establishes
the optimum receiving condition automatically. Amplifier section employs the
Duo-Beta Circuit for improved audio performance.

Flasher
Tuning System Indicator
In case of
FM reception, this indicator shows the direction of tuning. When a broadcasting
station is coming near, the indicator begins flashing. Turn he tunning knob
slowly to the direction shown by the indicator, and the flashing ceases at a
point where the precise tuning point is obtained. At this time, the indicator
shows the signal strength of the station
just tuned in. When 3 or more indicators light up, stble reception in
stereo mode is feasible.
C.A.T. off
Switch
Thanks to
our innovative C.A.T. (Computer Analized Tuning) circuitry, this
tuner-amplifier always provides an optimum reception according to the ambient
conditions. Specifically, the anti-birdie and noise canceller circuits are
sensing the electric field strength, interference by other stations, etc.
