Chapter 1 Getting Started
For higher quality recording/playback
* B and C type Dolby* NR systems which reduce tape noise.
* Dolby HX PRO* system for higher linearity in the tape's
high-range response during recording.
For your convenience
* Automatic tape type detection during playback and
recording.
* A relay function for long playback.
* Synchronized dubbing at normal or high speed.
For easier operation
* Twin easy-to-read digital counters showing the elapsed
recording or playing time on each deck.
* Dolby noise reduction and HX Pro headroom extension
manufactured under license from Dolby Laboratories Licensing
Corporation. HX Pro originated by Bang & Olufsen.
“DOLBY”, the double-D symbol 00 and “HX PRO” are trademarks
of Dolby Laboratories Licensing Corporation.
Precautions
On safety
*Should any solid object or liquid fall into the cabinet,
unplug the unit and have it checked by qualified personnel
before operating it any further.
* Unplug the unit from the wall outlet if it will not be used
for a long time. To disconnect the cord, pull it out by
grasping the plug. Never pull the cord itself.
*The unit is not disconnected from the AC power source
(mains) as long as it is connected to the wall outlet, even if
the unit itself has been turned off.
On operation
*When the unit is not used, turn the power off to conserve
energy and to extend the useful life of your unit.
* Because of a safety mechanism, the function buttons will
not operate if the cassette holder is not completely closed, if
there is no cassette in the cassette holder, or if a cassette has
been incorrectly inserted into the cassette holder.
On head cleaning
The head and tape path should be cleaned after every ten
hours of operation. Dirty heads and a dirty tape path may
cause:
— loss of high-frequency response
— loss of sound volume
— sound drop-out
If you have any questions or problems concerning your unit,
please contact your nearest Sony dealer.
For the customers in the U. S. A.
For detailed safety precautions, see the leaflet “IMPORTANT
SAFEGUARDS".
Checking the Supplied Accessories
Make sure that the following supplied accessories are
included with your unit.
* Audio connecting cords (2)
Notes on Installation
* Place the unit with the front panel facing you in a location
with adequate air circulation to prevent overheating of the
unit.
* Do not place the unit:
— near heat sources such as radiators or air ducts.
— in places subject to direct sunlight, excessive dust,
mechanical vibration or shock.
— in an inclined position.
— On a rug or other soft surfaces that would block the
ventilation holes on the bottom of the unit.
Do not throw away the carton and the packing
material
They will come in handy when transporting the unit or
shipping it for servicing.
Checking the Operating Voltage
eOperate the unit only on 120 V AC, 60 Hz (U.S.A. and
Canada models), 240 V AC, 50 Hz (U.K. model) or 240 V
AC, 50/60 Hz (Australia model).
* Before connecting the unit to an AC outlet, be sure that the
operating voltage of your unit is identical with that of your
local power supply.
Hooking Up the System
Before You Begin
*Turn off the power to all equipment to be connected before
making any connection.
* Note that the red plug of the supplied connecting cord is
for right-channel (R) connection and the white plug for left-
channel (L) connection.
*The connecting cords should be fully inserted into the jacks.
A loose connection may cause hum pickup.

recorded material.
When both decks A and B are in playback mode
Only playback from deck A will be audible. However, a
short break in sound output will occur after the activation of
the second deck.
What is the Dolby NR system?
The Dolby NR (noise reduction) system reduces tape hiss
noise in low-level, high-frequency signals by boosting the
signals during recording and lowering them during
playback.
Note
The Dolby HX PRO system works only during recording, not
during playback.

exceeding the recommended range for the inserted tape.

Tips on recording level adjustment
Setting the recording level too low will produce a hissing
sound, while setting it too high will produce distortion.
Generally, the proper recording level for high and low
frequencies is lower than that for middle frequencies.
When recording program sources with many high and low
frequencies, set the level to a relatively low position, then
make adjustments according to the recording results.
What Is the Dolby HX PRO System?
The Dolby HX PRO system provides precise bias control
during recording to reduce distortion and improve linearity
in the high-frequency range. The result is recorded sound
that is highly faithful to the original. Since the HX PRO
system operates only during recording, the same high-
quality sound is produced even during playback on other
tape decks. The HX PRO system is independent from the
Dolby NR system and is unaffected by the Dolby NR setting.

Cassette care
* Avoid touching the tape surface of a cassette to prevent
contamination of the heads by dirt, dust, or vil on the skin.
+ Keep cassettes away from equipment with magnets, such
as speakers and amplifiers, as erasure or distortion of the
recorded tape could occur.
* Do not expose cassettes to direct sunlight, extremely cold
temperatures, or moisture.
Note on cassettes longer than 90 minutes
We do not recommend the use of cassettes longer than 90
minutes except for long continuous playback.
Chapter 4 Other Operations
Dubbing a Tape

During high-speed dubbing
Only the BB button is operative.
If the NORM or HIGH speed indicator flashes three

Either one or both tabs of the cassette inserted into deck B
have been removed, making dubbing impossible for that
side. Cover the hole(s) with tape (see page 10).
К is unnecessary to adjust the recording level and
select the Dolby NR system
The tape in deck B is automatically recorded with the same
recording level and Dolby noise reduction system as the
original in deck A.
The Dolby system must, however, be set to match the tape in
deck A when the sound is monitored during normal-speed
dubbing.
Note on tape dubbing
If the sound is affected by the proximity of a television set
during high-speed dubbing, turn the television set off or
move it away from the deck.

Follow this procedure to dub only specific portions of
selections. Note that this is only possible in the normal-speed
dubbing mode.
1 During dubbing, press ll on deck A at the

Maintenance
Cleaning the Heads and Tape Path
Clean all surfaces over which the tape travels after every ten
hours of operation to guard against:
— low-quality sound
— a decrease in sound level
— excessive wow, flutter or drop-out
— incomplete erasure
— impairment of recording function
To obtain high-quality recorded sound, we recommend
cleaning before every recording.
1 Press 2 to open the cassette holder. Grasp the
front holder on both sides and gently lift to
remove it.
2 With the unit turned off, wipe the heads, the
pinch rollers and the capstans with a cotton
swab slightly moistened with alcohol or a
commercially available cleaning fluid for tape
decks.
3 Replace the cassette holder.

Demagnetizing the Heads
After 20 to 30 hours of use, or when you notice hiss and/or
loss of high frequencies, the residual magnetism built up on
the heads should be removed.
1 Turn off the power.
2 Demagnetize the heads with any commercially
available demagnetizer.
Refer to the instruction manual of the
demagnetizer for detailed instructions.
Cleaning the Cabinet
Clean the cabinet, panel and controls with a soft cloth
slightly moistened with a mild detergent solution.
Do not use any type of abrasive pad, scouring powder or
solvents such as alcohol or benzine.
