audio/video control center that allows you to enjoy with
maximum convenience a variety of audio/video program
sources—CD (Compact Disc), record, tape, TV, hi-fi video,
and more.
e A surround sound system gives your living room the
acoustics of a movie theater or a concert hall.
¢ The ASP (Audio Signal Processor) IC developed by Sony
can digitally control the tone and volume settings, and
permits electronic program source selection with a single
touch of a key.
¢ The ASP IC also offers an acoustic memory function, an
ability to store and recall three sets of tonal adjustments,
and a volume fade-in function, an ability to set the volume
to the minimum level when the power is turned on and
automatically increase it to a previously set level.
¢ A quartz-locked digital synthesizer system with a
sophisticated Phase-Locked Loop (PLL) circuit allows
extremely precise tuning of FM and AM stations with an
electronic digital readout in the display window.
A total of 10 stations can be preset.
¢ The computerized logic tuning system automatically
selects the appropriate FM mode and FM IF band
according to the signal strength of the station received.
¢ The station spectrum display allows you to identify at a
glance the frequencies of all preset stations or stations
which are receivable with station scan tuning.
e Video tapes can be edited between two hi-fi video cassette
recorders connected. During video tape editing, other
audio program sources can be enjoyed and added onto the
video tape.
e Independent TV tuner inputs are provided besides the two
video inputs.
e Front video inputs allows temporary connection of a
portable VCR, etc.
¢ CATV cable can be connected directly to the receiver,
making FM simulcast program reception easily.

PRECAUTIONS
On safety
¢ Operate the unit only on 120 V AC, 60 Hz.
e Should any liquid or solid object fall into the cabinet,
unplug the unit and have it checked by qualified personnel
before operating it any further.
e Unplug the unit from the wall outlet if it is not to be used for
an extended period of time. To disconnect the cord, pull it
out by prasping the plug. Never pull the cord itself.
¢ One blade of the plug is wider than the other for the
purpose of safety and will fit into the power outlet only one
way. If you are unable to insert the plug fully into the outlet,
contact your dealer.
On installation
¢ Do not install the unit in a location near heat sources such
as radiators or air ducts, or in a place subject to direct
sunlight, excessive dust, mechanical vibration or shock.
¢ Good air circulation is essential to prevent internal heat
build-up in the unit. Place the unit in a location with
adequate air circulation. Do not piace the unit on a soft
surface, such as a rug that would block the ventilation
holes on the bottom.
¢ Do not place anything on top of the cabinet. The top
ventilation holes must be unobstructed for the proper
operation of the unit and to prolong the life of its
components.
On operation
e Before making program source connections, be sure to
turn the power switch off and unplug the unit.
e¢ When the unit is not used, turn the power off, to conserve
energy and to extend the useful life of your unit.
On cleaning the cabinet
Clean the cabinet, pane! and controls with a soft cloth lightly
moistened with mild detergent solution. Do not use any type
of abrasive pad, scouring powder, or solvent such as alcohol
or benzine.
On repacking
Do not throw away the carton and the packing material. It
makes an ideal container to transport the unit in. When
shipping the unit for repair work or to another location,
repack it as illustrated on the carton box.
For detailed safety precautions, see the “IMPORTANT
SAFEGUARDS” leaflet.
To change the AM tuning interval
The AM tuning interval is preset at the factory to 10 kHz to
match the frequency allocation system of your country.
If you use the receiver where the frequency allocation system
is based on a 9 kHz interval, change the interval as follows.
1 Depress the MAIN POWER switch to turn on the unit.
2 Press the SYSTEM POWER switch to turn off the unit.
3 While pressing the “+” STATION SCAN key, press the
SYSTEM POWER switch to turn the unit on.
The AM tuning interval has been set to 9 KHz. To reset the
interval to 10 KHz, follow the same procedure.
Note
When the interval is changed, all preset and located stations
and acoustic settings will be erased. After changing the
interval, memorize the stations and acoustic settings again.
