Overview

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.

Hooking Up the System

Connecting Speaker Systems

You can connect front, rear and center speakers to this unit.

On the IMPEDANCE selector (STR-D915 only)

The STR-D915 has the IMPEDANCE SELECTOR for front speakers. 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.

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.
