FEATURES
Dolby NR C-type noise reduction system
In addition to the conventional B-type Dolby NR system, this
cassette deck employs the newly-developed C-type Dolby
system which reduces tape noise twice as effectively as the B-type
system. The C-type system also incorporates an anti-saturation
network to improve the high-frequency dynamic range by 4 dB at 10
kHz.
Full-logic “feather-touch” operation
At the slightest touch, the “feather-touch” function buttons enable
you to switch directly from one mode to another without going
through the stop mode.
Blank skip function
Blank spaces of at least 10 seconds long can be skipped in the
forward mode so that only the recorded portions of the tape are
played back.
Music scan function
The first 10 seconds or so of all the selections on a tape can be
played back in sequence. Thus the particular selection can be
located easily.
Repeat play
Playback of one side of the cassette can be repeated five times. At
the end of the tape, the cassette deck will automatically go into the
rewind mode, and playback will be repeated from the beginning of
the tape.

to its optimum bias current for recording and the optimum
equalization for both recording and playback by simply Inserting

Auto playThe auto play function makes automatic replay possible promptly
after the tape is rewound to the beginning.
Remote control operation
Using the optional RM-50, RM-51 or RM-80 remote control unit,
various operations-recording, playback, AMS, record muting
operation, etc.-can be remotely controlled. When the RM-65 synchro remote control unit is used to connect this cassette deck with
a turntable equipped with a synchro remote control jack, the operation of the cassette deck and the turntable will be synchronized.
Timer-activated recording or playback
A timer switch is provided to turn the deck on and off at times

LEVEL METERS
These meters show the peak input level of each channel during
recording, and recorded levels in the playback mode. They follow

TROUBLE CHECKS
The following trouble checks will help you correct the most common problems encountered with a tape deck. Should any problem
persist after you have made these checks, consult your nearest
Sony service facility.
Before proceeding with these trouble checks, first check these
basic points
l
The power cord must be firmly connected.
l
0 Heads, capstan and pinch roller should be clean.
l The amplifier controls and switches should be set correctly.

0 No cassette in the holder.
l
The tab has been removed from the cassette.
The automatic shut-off mechanism activates before the end of the
tape.
l
The tape is slack.
l
This situation may also be caused by a deformed cassette shell.
Tape transport noise seems excessively loud in rewind or fast-
forward mode.
l
This situation depends upon the cassette used and is not a prob-
lem.
:
Amplifier connections must be firmly made.
