Aiwa Surround Sound Stereo Troubleshooting
Aiwa is a home electronics company that manufactures a variety of home theater products. Like most home theater brands, Aiwa surround sound systems include a speaker package connected to an audio/video receiver that processes signals from other components--such as a television or DVD player--to produce sound. Each speaker connects to the Aiwa receiver with a two-strand wire. If you experience problems with your Aiwa system, troubleshooting the equipment could resolve the issue and avoid a repair bill.
Lift the tabs on the speaker terminals on the back of the Aiwa to verify each two-strand wire is fully inserted, then press the tabs to lock the wires.
Push up on the levers on the back of each speaker to confirm the wires are properly connected to each speaker in the Aiwa system. If either of the two wire strands pulls loose, the speaker will not operate.
Press the "Surround" button on the Aiwa remote control with the receiver turned on to set the unit to surround sound mode. Increase the volume on the system either by pressing the "+" button on the remote control or dialing the volume knob clockwise on the Aiwa receiver.
Press the "Test" button on the Aiwa remote control. A test signal will play on each speaker connected to the receiver, confirming all the speakers are operational.
Disconnect any speaker that does not produce a test sound and connect a speaker that you know to be working to the wires. Run the test sequence again with the remote control to isolate the problem to a specific speaker. If the second speaker does not play, the receiver terminal connections or the amplifier inside the speaker may be damaged and will require repairs.
Dial the balance control knob on the front of the Aiwa receiver so that the notch on the knob is vertical, rather than favoring the left or the right. If the balance control is turned to one extreme or another, the opposite speaker will not be heard.
Play back a DVD or CD labeled "Surround Sound" on the packaging to be sure you are using a disc actually encoded for surround sound. Stereo CDs are recorded to produce just two-channel audio, not surround sound.
