Troubleshooting

If you 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.

/Turn INPUT SELECTOR to the appropriate programme source.

/Make sure the speaker wires are correctly connected to the SPEAKERS A terminals (on the bottom row) and SPEAKERS B terminals (on the top row).

/Make sure the proper selection is made on the SPEAKERS control (A, B, A+B, or OFF).

No audio from one channel or unbalanced speaker output.

/Turn BALANCE to adjust the balance.

/Check the speaker and input connections of silent channel.

Weak bass or treble.

/Adjust the TONE controls.

/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.

The remote does not function.

/Remove any obstructions between the remote control sensor on the amplifier and the remote.

/Point the remote towards the remote sensor on the front of the amplifier.

/The remote is too far from the amplifier. Move closer to the amplifier.

/Replace the batteries in the remote.

The PROTECTION indicator lights up and/or sudden loss of audio.

/Check if a short-circuit has occurred. Turn off the amplifier and check the connected components and speakers.
