1.If the amplifier is being used in a Synthesis system, make sure that the surround processor is turned on, the Auto On/Manual On switch is in the Auto On position, and that all of the necessary DIN cables are connected between the various system components. Refer to the "CONNECTING YOUR SYNTHESIS SYSTEM" section for reference.

2.If the amplifier is not being used with a Synthesis system, make sure that the Auto On/Manual On switch is in the Manual On position.

Problem: There is no sound from the speakers, but the amplifier is on (blue indicators lit).

1.Make sure that the surround processor or equalizer is on, and that the correct source has been connected and selected.

2.Make sure that the correct outputs are connected from the surround processor or equalizer to the amplifier.

3.Make sure that the speakers are connected to the correct terminals. Check for short circuits at both ends of the speaker cables.

Problem: Not all of the amplifiers turn on in a Synthesis system.

1.Make sure that all required DIN cables are connected between system components. Refer to the "CONNECTING YOUR SYNTHESIS SYSTEM" section.

2.Make sure that each amplifier has its Auto On/Manual On switch in the Auto On position.

Problem: Insufficient audio from the speakers.

Check that the output levels of the surround processor or equalizer are set properly.

Problem: Insufficient bass.

Verify that the speakers have been wired to the amplifier with the correct polarity.

Problem: Speakers do not switch from music to cinema mode.

1.Make sure that the screw terminal and DIN adapter cables to speakers are correctly wired and are connected to the correct jacks on the S650A or S7150.

2.Make sure that all required DIN cables are connected between system components.

Problem: Audible hum from the speakers.

1.Check the power outlets and make sure that there is a solid earth ground present. (The services of an electrician may be required.)

2.Make sure that all signal cables are routed away from power cords.

3.If these suggestions fail, experiment by running ground wires between the rear panel screws of the amplifiers and the other system components, such as the surround processor or signal processing package.
