Precautions
The STR-D915/D715 is an FM Stereo/FM-AM receiver and
audio/video control center.
You can enjoy various audio/video program sources with
this unit.
TV/video programs
• You can enjoy TV or CATV programs with FM simulcast.
• Sounds from various audio program sources can be added
on video tapes during editing.
Tuner
• Precise tuning is ensured by a quartz locked digital
synthesizer.
• Station Index system allows you to tune into a station
quickly.
DOLBY* PRO LOGIC
In the DOLBY SUR or THEATER mode, the center mode can
be selected. The Dolby Pro Logic Surround Decoder has the
same functions for playback as movie theaters and gives a
theater-like experience in your listening room, naturally
reproducing the audio sound field.
• Manufactured under license from Dolby Laboratories Licensing
Corporation. Additionally licensed under one or more of the
following patents: U.S. number 3,959,590; Canadian numbers
1,004,603 and 1,037,877. "DOLBY", "Pro Logic", and the double-D
symbol are tradeituirks of Dolby Laboratories Licensing
Corporation.
Sound field (combination of digital delayed surround and tone controls)
• 6 recommended sound field programs (DOLBY SUR,
THEATER, LIVE, HALL, DANCE, ACOUSTIC) are preset
in the factory for easy use. You can also store up to 6
settings you created in the memory.
• Combined use of the sound held programs and the preset
stations or program source allows you to enjoy broadcast
or program source listening immediately with the
memorized 6 settings of sound field (DOLBY SUR,
THEATER, LIVE, HALL, DANCE, ACOUSTIC).
Remote commander
The supplied remote commander allows you to remotely
control this receiver and the equipments connected to the
receiver.
For the instruction of the remote commander, see pages 16
and 17.
As for the instruction of the remote commander for STRD915 Canadian model, see the operating instructions of the
separate volume.
On safety
• For the U.S.A. and Canadian models, operate the unit
only on 120 V AC, 60 Hz.
• For Australian model, operate the unit only on 240 V AC,
50 Hz.
• 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 is not to be used
for an extended period of time. To disconnect the cord,
pull it out by grasping 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, (except for Australian model)
• 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
Before making program source connections, be sure to
turn the power switch off and unplug the unit.
To prevent internal heat buildup in the unit,
place the unit in a location with adequate air circulation.
Do not install the unit:
• near heat sources such as radiators or air ducts.
• in a place subject to direct sunlight, excessive dust,
mechanical vibration or shock.
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 cleaning the cabinet
Clean the cabinet, panel 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.
For the customers in the U.S.A.
For detailed safety precautions, see the "IMPORTANT
SAFEGUARDS" leaflet.
If you have any question or problem concerning your unit,
please consult your nearest Sony dealer.

Inserting Batteries into the Remote
Commander
Before operating the remote commander, install the batteries
as shown below.
Open the cover.
Insert two size-AA (R6) batteries with
correct poiarity.
To avoid damage caused by battery leakage and corrosion
When the commander will not be used for a long time,
remove the batteries.
Battery life
Normal operation can be expected about a half year using
Sony SUM-3 (NS) (size-AA), and a year using Sony AM-3
(NW (size-AA) alkaline batteries.
When the batteries are run down, the remote commander
will not operate the unit. In this case, replace both batteries
with new ones.
Hooking Up the System
Notes on Connections
At first, this section describes about the connection with the other equipments, the antenna connection,
speaker connection and then the AC power connection.
• Do not connect the power cord to an AC wall outlet until you complete other connection.
• The cable connectors should be fully inserted into the jacl«. Loose connection may cause hum and noise.
• Jacks and plugs of the connecting cord are color*coded as follows:
Red jacks and plugs: For the right channel of audio signals
White jacks and plugs: For the left channel of audio signals
Yellow jacks and plugs: For video signals
Connecting Audio Equipment
Connecting Video Equipment
Connecting an FM Antenna
Connecting the Antenna Ground
Though the wire antenna is supplied with this unit, the
higher quality sound will be obtained with the 75-ohm
coaxial cable, (not supplied)
To prevent hum, connect the ground wire to ANTENNA
ground terminal (/k).
When an outdoor antenna is installed, be sure to connect the
ground wire for lightning protection.
Connecting an AM Antenna
The AM broadcast is adequate with the supplied AM loop
antenna. However, the connection of insulated wire is also
available for areas with difficult AM reception.
AM antenna extension
For best reception, attach a length of insulated wire (6 -15 m
long) to the AM ANTENNA terminal in addition to the loop
antenna.

When using the front speakers having nominal impedance
from 4 ohms or higher, set to the 4 D position.
When using the front speakers having nominal impedance
from 8 ohms or higher, set to the 8 D position.
Note
Use the front speakers having nominal impedance of more
than 8 ohms in the SURROUND mode.
Note
When connecting the speaker cord to the speaker terminal,
make sure that the polarity (+ and -) of the speaker cord is
correct. If the polarity is reversed at either speaker, the
sound will be distorted and will lack bass.
8
Connecting to the AC Power Outlet
Connect the AC power cord to the wall outlet last of all.
By connecting the power cord of the other audio equipment
to SWITCHED AC OUTLET, this unit can supply the power
source to the other audio equipment.
Caution
Be careful that the total power consumption of each
equipment connected to the outlets on the receiver does not
exceed 120 watts (for U.S.A. and Canadian models) or 100
watts (for Australian model).
Do not connect electrical home appliances such as an electric
iron, fan, TV, or other high-wattage equipment to these
outlets.

the closest value covered by the tuning interval.
Timing intervals for direct tuning are the followings:
FM: 50 kHz interval
AM; 10 kHz interval (for U.S.A. and Canadian modeb)
9 kHz interval (for Australian model)
(To switch the tuning interval between 9 kHz and 10 kHz,
