Audio

There’s no sound, or it’s very quiet?

•Make sure that all audio connecting plugs are pushed in all the way (page 20).

•Make sure that the inputs and outputs of all compo- nents are connected properly (page 20).

•Make sure that the polarity of the speaker cables is correct, and that the bare wires are in contact with metal part of each speaker terminal (page 22)

•Make sure that the input source is properly selected (page 44).

•Make sure that the speaker cables are not shorting.

•Check the volume. It can be set to MIN, 1 through 99, or MAX (page 44). The AV receiver is designed for home theater enjoyment. It has a wide volume range, allowing precise adjustment.

•If the MUTING indicator is shown on the display, press the remote controller’s [Muting] button to unmute the AV receiver (page 45).
