SONY STR-V5 (01) PDF Document

To ensure the safe operation of your SONY STR-V5, please follow these precautions:

On Safety:

• Check that the operating voltage of your unit is identical to the voltage of your local power supply.

• If any liquid or solid object falls into the cabinet, unplug the unit and have it checked by qualified personnel before operating it further.

• Unplug the unit from the wall outlet if it will not be used for an extended period. To disconnect the cord, pull it out by grasping the plug, not the cord itself.

• In compliance with safety regulations, do not remove the side boards. If necessary, consult your nearest Sony dealer.

• To prevent fire or shock hazard, do not expose the unit to rain or moisture.

• To avoid electrical shock, do not open the cabinet. Refer servicing to qualified personnel only.

On Operation:

• Do not overload the outlets from which your music system operates by simultaneously using high wattage devices such as electric irons or hair dryers.

• Before making program source connections, be sure to turn the power switch off and unplug the unit.

• Do not attempt to test the protection circuits by blocking the ventilation holes or connecting improper loads.

• When the unit is not used, turn the power off to conserve energy and extend the useful life of your unit.

For proper installation of your SONY STR-V5, follow these guidelines:

• 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 buildup. Place the unit in a location with adequate air circulation. Do not place it on soft surfaces like a rug that could block the bottom ventilation holes.

• Do not place anything on top of the cabinet. The top ventilation holes must be unobstructed for proper operation and to prolong the life of its components.

• Allow more than 15 cm (6 inches) of space behind the unit so that the position of the built-in ferrite-bar antenna can be adjusted.

After unpacking your SONY STR-V5, inspect the unit immediately. If any sign of damage is found, consult your local Sony dealer. It is recommended to not throw away the carton and associated packing material, as they will be useful if you ever need to transport or ship your unit. When shipping the unit for repair or to another location, it should be repacked in the original carton and packing material.

• To assure correct matching at the input and output terminals, refer to the “SPECIFICATIONS” section. Generally, the output level of a signal source should be equal to or slightly greater than the sensitivity of the corresponding input, and the output impedance of the source should be considerably lower than the input impedance of the receiver.

• For all program source connections, use a low-capacitance type shielded cable. Keep cables as short as possible and avoid horizontal runs. Runs over 2 meters (6 feet) can reduce high-frequency response, and horizontal runs are susceptible to power line hum pickup.

• Ensure cable connections are fully inserted into the jacks. A loose connection may cause hum and noise.

• If reconnections are made, lower all source level controls and turn off the receiver to avoid possible speaker damage.

• Be sure to connect the red plug to the right [R] jack and the other plug to the left [L] jack.

Power Connection:

Before making any power connection, ensure the receiver’s POWER switch is OFF. Then, plug the AC power cord into a wall outlet.

AC Outlets:

The receptacles on the rear panel provide a convenient source of AC power for other system components.

• SWITCHED outlet: This is controlled by the receiver’s POWER switch and can supply AC power up to 100 watts.

• UNSWITCHED outlet: This outlet has a 300-watt rating and is not controlled by the front panel POWER switch; it is always on when the receiver is plugged in.

Caution: Never run electrical home appliances such as an electric iron, fan, or TV from these outlets.

The SONY STR-V5 has provisions for two pairs of speaker systems (A and B). Follow these steps to connect them:

1. Speaker Impedance: The receiver is designed to work best with speakers having nominal ratings from 8 to 16 ohms. Do not use speakers with an impedance less than 8 ohms.

2. Speaker Cable: For short runs, common 18-gauge lamp cord is sufficient. For longer runs, 16-gauge or 14-gauge wire may be needed to prevent power loss.

3. Connecting the Cord:

a. Strip approximately 15 mm (5/8 inch) of the outer covering from the speaker cord.

b. Twist the bare wire ends for easy insertion. Do not coat them with solder.

c. Press the terminal button on the receiver’s rear panel.

d. Fully insert the twisted wire into the slot.

e. Release the terminal button to secure the wire.

f. Lightly pull the speaker cord to ensure the connection is secure.

4. Correct Phasing: Connect each speaker to the corresponding receiver terminals (Right speaker to R terminals, Left speaker to L terminals). Ensure the colored or marked lead of the speaker cord connects to the (+) terminal and the remaining lead connects to the (-) terminal on both the speaker and the receiver. Incorrect phasing can result in missing bass tones and an obscure stereo image.

Note: When using both speaker systems A and B simultaneously (SPEAKERS selector at “A+B”), both sets of speakers must be connected, as they are internally connected in series. No sound will be heard if only one speaker system is connected in this mode.

Follow these suggestions for optimal speaker placement:

• Normally, place speakers on the floor against the narrower wall of a room, spaced 2-3 meters (6-10 feet) apart and nearly equidistant from the center of the wall.

• To increase bass, move the speakers toward the corners. To decrease bass, raise the speakers off the floor on pedestals or move them away from the wall.

• If speakers are positioned above the floor, do not place them higher than ear level while seated to avoid an unnatural effect.

• In a large room, moving speakers toward the corners can create a “hole in the middle” effect. This can be partially counteracted by angling the front of the speakers toward the center of the room (your listening position).

• Place the right and left speakers in similar acoustic environments to maintain balanced sound. For example, placing one speaker near an open doorway can decrease its apparent bass.

• The best listening position is typically centered between the speakers, forming a triangle where the angle at the listening position is about 50-60 degrees.

• A room with carpeting, heavy draperies, and upholstered furniture generally provides the best sound. Some experimentation with placement is often necessary to achieve the correct balance of stereo image and bass response for your specific room.

Record Player:

Connect the cables from your record player to the PHONO input jacks on the rear panel. The PHONO inputs are designed for a low-to-medium output cartridge. Connect the ground wire from the record player to the GROUND terminal on the receiver to prevent hum.

Tape Recorders:

The receiver has connections for two tape decks (TAPE 1 and TAPE 2).

• To play back tapes, connect the LINE OUTPUT jacks of your tape recorder to the corresponding TAPE INPUT jacks on the receiver (e.g., Tape Deck 1 output to TAPE 1 input).

• To record, connect the LINE INPUT jacks of your tape recorder to the corresponding REC OUT jacks on the receiver (e.g., Tape Deck 1 input to REC OUT 1).

Other Input Sources (Auxiliary):

The auxiliary inputs (AUX) on the rear panel are for connecting various other line-level sources, such as a cassette player, an additional tuner, or a record player with a ceramic cartridge. Connect the output of the source to the AUX input jacks.

The SONY STR-V5 accepts either 300-ohm twin lead or 75-ohm coaxial cable for FM antennas. The supplied ribbon antenna can be used until a more permanent outdoor antenna is installed.

For 300-ohm Twin Lead Connection (like the supplied ribbon antenna):

1. Connect the two leads of the antenna wire to the two terminals marked FM 300Ω.

2. For optimum reception with the ribbon antenna, fully extend it and fasten the ends to a wall.

3. To avoid signal loss, use stand-off insulators if routing the lead over a roof or wall, keep the lead as short as possible, and avoid long horizontal runs.

For 75-ohm Coaxial Cable Connection:

1. Prepare the cable: Cut and remove about 15mm (1/2″) of the outer covering, shield braid, and inner covering to expose the center conductor. Fold back the shield braid. Be careful not to damage the center conductor.

2. Loosen the screws on the FM 75Ω ANTENNA plate and terminal.

3. Pass the cable under the plate, wind the center conductor around the terminal, and tighten the screws. The shield braid should make contact with the ground plate.

A shielded coaxial cable is recommended in areas with local noise (like ignition noise) or multipath interference.

In most areas, the built-in ferrite-bar antenna on the rear panel will provide satisfactory AM reception. Simply position the antenna as shown in the manual for the best reception.

In difficult reception areas, you may need to connect an external AM antenna:

1. Connect a length of insulated wire, 5-15 meters (20-50 feet) long, to the AM ANTENNA terminal.

2. Extend this wire out of doors if possible, keeping the greater portion horizontal.

3. To check signal strength, set the METER switch to SIGNAL; the stronger the signal, the greater the deflection to the right on the meter.

1. First, ensure the POWER switch is released (OFF) and the receiver is plugged into a suitable power outlet.

2. Set the controls to their “Basic control settings”:

• Set the VOLUME control to its minimum position (fully counter-clockwise).

• Set all tone controls (BASS, TREBLE) to the center DEFEAT position.

• Set FILTER and LOUDNESS switches to OFF.

• Set the BALANCE control to the center position.

• Set the MODE selector to STEREO.

3. Select the desired program source using the FUNCTION and TAPE selectors. The table below shows the required settings:

4. Depress the POWER switch to ON. The receiver has a muting circuit that delays audio for a few seconds to avoid a “thump” noise.

5. Your receiver is now ready for operation, and you can proceed with sound adjustments.

Sound Volume:

Adjust the VOLUME control to the desired level by turning it clockwise. Keep the power ratings of your receiver and speakers in mind. You can observe the output level on the POWER meters by setting the METER switch to POWER.

Stereo Balance:

Stereo balance can be affected by room acoustics and speaker placement. To adjust:

1. Set the MODE selector to MONO.

2. Adjust the BALANCE control until you hear equal output from the right and left speakers.

3. Return the MODE selector to STEREO for a well-defined stereo image.

Tone Controls:

The TONE controls (BASS and TREBLE) can be used to adjust the sound quality. However, overuse may adversely affect it. For proper use, refer to the “TONE CONTROL SECTION” on page 13 of the manual.

1. For FM reception, set the FUNCTION selector to FM. For AM reception, set it to AM.

2. Tune in the desired station with the TUNING knob.

3. Adjust the volume and tone quality to your preference.

Tuning Indicators:

• FM Tuning: The correct tuning point is shown by the maximum rightward deflection of the SIGNAL strength meter (with the METER switch depressed to SIGNAL) and the center position of the TUNING meter. When receiving an FM stereo signal, the STEREO lamp will light up automatically.

• AM Tuning: The correct tuning is shown by the maximum rightward deflection of the SIGNAL strength meter.

Notes:

• To tune in a very weak FM station, lower the volume and set the FM MUTING switch to OFF.

• If the STEREO lamp flickers on a weak stereo signal, adjust the antenna. If noise persists, set the MODE selector to MONO for the best possible signal.

Record Playing:

1. Set the FUNCTION selector to PHONO.

2. Play the record on your turntable.

3. Adjust the volume and tone quality to your preference.

Tape Playback:

1. Set the TAPE selector to TAPE 1 (for a tape deck connected to TAPE 1 jacks) or TAPE 2 (for a deck connected to TAPE 2 jacks).

2. Start the tape playback on your tape deck.

3. Adjust the volume and tone quality to your preference.

Tape Recording:

1. Set the TAPE selector to SOURCE.

2. Select the program you want to record with the FUNCTION selector (e.g., PHONO for a record, FM for radio).

3. Adjust the recording level on your tape recorder and start it in record mode.

4. Play the desired program.

Note: The VOLUME, BALANCE, TONE controls, LOUDNESS, and FILTER switches on the receiver have no effect on the signal sent to the REC OUT jacks for recording. You can make two recordings simultaneously by using two tape recorders.

You can copy a tape from one tape recorder to another while listening to the program being copied.

To copy from Tape Recorder 1 to Tape Recorder 2:

1. Set the TAPE selector to COPY 1→2.

2. Adjust the recording level on tape recorder 2, and start it in record mode.

3. Start the playback of tape recorder 1. The copy will begin.

To copy from Tape Recorder 2 to Tape Recorder 1:

Follow the same procedure, but set the TAPE selector to COPY 2→1.

General Controls:

• POWER switch: Depress to apply power. The dial scale and meters will light up. Depress again to turn off.

• SPEAKERS selector: Selects speakers A, B, both (A+B), or OFF (for headphone use).

• BALANCE control: Regulates the sound balance between right and left channels. Normally set to the center position.

• MODE selector: Normally set to STEREO. Set to MONO for weak/noisy FM stereo signals or when adjusting balance.

• VOLUME control: Regulates the overall sound level.

Input Selection:

• FUNCTION selector: Selects the main program source (PHONO, FM, AM, AUX).

• TAPE selector: Selects the source for listening or tape copying (SOURCE, TAPE 1, TAPE 2, COPY 1→2, COPY 2→1).

Tone Controls:

• FILTER switches (LOW, HIGH): Attenuate low-frequency rumble or high-frequency hiss/scratches. Set to OFF when not needed.

• TONE controls (BASS, TREBLE): Adjust bass and treble frequencies. The DEFEAT position provides a flat response.

• LOUDNESS switch: When ON, boosts low and high frequencies at low volume levels to compensate for human hearing characteristics. For normal operation, set to OFF.

Terminals and Meters:

• HEADPHONES jack: Accepts stereo headphones. Set SPEAKERS selector to OFF for headphone-only listening.

• METER switch: When released (out), meters show POWER output. When depressed (in), the right meter functions as a SIGNAL strength meter.

• TUNING meter: Acts as a center-of-channel indicator for FM tuning.

Tuner Section:

• FM MUTING switch: When ON, eliminates inter-station noise while tuning. Set to OFF to tune very weak stations.

• TUNING knob: Selects the desired FM or AM station.

• STEREO lamp: Lights when a stereo FM program of sufficient strength is tuned in.

If there is no sound, check the following:

• Depress the POWER switch to turn the unit on.

• Check that the AC power cord is plugged into a working outlet.

• Check the speaker cord connections at both the receiver and the speakers.

• For program sources other than tape, set the TAPE selector to SOURCE.

• Check the setting of the FUNCTION selector to ensure it matches your desired source.

• Check the SPEAKERS selector setting. It should not be in the OFF position. If set to A+B, ensure speakers are connected to both A and B terminals.

• Turn up the VOLUME control.

These symptoms may be caused when the protection circuits activate.

• Abrupt loss of sound from one or both speakers: Check the speaker terminals or speaker cord for a short circuit (e.g., stray wire strands touching each other or the chassis).

• Abrupt loss of sound from both speakers, and the unit is extremely hot: Remove any objects on the top or the cabinet which might be preventing normal air circulation by blocking the ventilation holes.

Allow the unit to cool down before attempting to use it again. If the problem persists after correcting any issues, consult your Sony dealer.

The SIGNAL strength meter is unstable.

• Adjust the antenna position and orientation for the strongest, most stable signal.

The STEREO lamp does not light when receiving stereo programs.

• Set the MODE selector to STEREO.

Severe hum or noise (from radio).

• Tune the station accurately using the meters.

• Use a shielded antenna lead (coaxial cable).

• Avoid long horizontal runs of antenna lead.

• Adjust the antenna for best reception.

Ignition noise (popping or ticking from car engines).

• Install the antenna away from heavy traffic.

• Use a coaxial cable for the FM antenna connection.

Unbalanced left and right volume.

• Adjust the BALANCE control on the receiver.

• Check the level or balance controls of the signal source component.

Reversed left and right sound.

• Check the speaker cord connections and speaker location. Ensure the left speaker is connected to the left terminals and the right speaker to the right terminals.

Lack of bass or obscure instrument position.

• This is often caused by incorrect speaker phasing. Check that the speaker connections are correct (+ to +, – to -) for both speakers.

Severe hum or noise (from non-radio sources).

• Use shielded connecting cords for your components.

• Keep connecting cords away from transformers or motors and at least 3 meters (10 feet) from TV sets and fluorescent lights.

• Ground the receiver by connecting the ground terminal to a proper earth ground.

Rustling noise.

• Make sure all connections are secure.

• Wipe the plugs and jacks with a cloth lightly dampened with methanol.

No tape recording:

• Check the TAPE selector setting. For recording from a radio or auxiliary source, it must be set to SOURCE.

No tape copying (dubbing):

• Check that the TAPE selector is correctly set to either COPY 1→2 or COPY 2→1, depending on the direction of the copy.

Clean the cabinet, panel, and knobs periodically with a soft cloth. If fingerprints, food, and beverage stains are difficult to remove, use a cloth moistened with a mild detergent solution. Do not use any type of scouring powder, abrasive pad, or solvent, as these will damage the cabinet’s finish.
