Troubleshooting

If you’ve experience any of the following difficulties while
using the amplifier, use this troubleshooting guide to help
you remedy the problem. Should any problem persist,
consult your nearest Sony dealer.

No sound output.

/ Connect the audio connecting cords firmly.
/ Connect the amplifier and other audio components

correctly.

/ Set SPEAKERS to ON (see page 6).
/ Turn INPUT SELECTOR to the appropriate

programme source.

No audio from one channel or unbalanced speaker
output.

/ Turn BALANCE to adjust the balance.
/ Check the speaker and input connections of silent

channel.

Sudden loss of audio and the POWER indicator lights up
red.

/ The speaker cords have been shorted. Make sure they

are connected correctly.

Weak bass or treble.

/ Adjust the TONE controls.
/ Press CARTRIDGE to select the appropriate cartridge

type (see page 5).

/ Change speaker positions or room conditions to

eliminate obstructions in sound path.

Distorted sound.

/ Improperly selected input signal.
/ Insufficient input capacity of speakers. Lower the

volume.

Lack of bass or ambiguity in instrument positions.

/ Speaker cord and terminal polarity are reversed.

Reconnect the cords with correct polarity.

Hum or noise.

/ Ground the turntable system (see page 5).
/ Connect the audio connecting cords firmly.
/ The amplifier is picking up interference from a TV set.

Move the amplifier away from the TV set or turn the
TV set off.

Cannot record.

/ Turn REC OUT SELECTOR to the appropriate

programme source.

/ Set REC OUT to ON (see page 7).
