Troubleshooting

If you have any trouble using your DTR-8.4, look for a solution in this section. If you can’t resolve the issue yourself, contact your Integra/Onkyo dealer.

Power

Can’t turn on the DTR-8.4?

•Make sure that the power cord is properly plugged into the wall outlet. Make sure that the other end of the power cord is properly connected to the DTR-8.4’s AC INLET.

•Unplug the power cord from the wall outlet, wait five seconds or more, then plug the cable in again.

The DTR-8.4 turns off as soon as it’s turned on?

•The amp protection circuit has been activated. Remove the power cord from the wall outlet immedi- ately and contact your Integra/Onkyo dealer.

Audio

There’s no sound, or it’s very quiet?

•Make sure that all audio connecting plugs are pushed in all the way (page 26).

•Make sure that the inputs and outputs of all compo- nents are connected properly (page 26).

•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 23)

•Make sure that the input source is properly selected (page 51).

•Check the volume. It can be set from 0 to 100 (page 51).

The DTR-8.4 is designed for home theater enjoyment. It has a wide volume range, allowing precise adjust- ment.

•If the MUTING indicator is shown on the display, press the remote controller’s [Muting] button to unmute the DTR-8.4 (page 52).

•While a pair of headphones is connected to the PHONES jack, no sound is output by the speakers (page 52).

•Check the digital audio output setting on the con- nected device. On some games consoles, such as those that support DVD, the default setting is off.

•With some DVD-Video discs, you need to select an audio output format from a menu.

•Make sure that the correct input signal audio format is selected with the [Audio Selector] button (page 53).

(page 35).

The surround speakers produce no sound?

•When the Stereo, Direct, or Pure Audio listening mode is selected, the surround speakers produce no sound (page 56).

•Depending on the source and current listening mode, not much sound may be produced by the surround speakers. Try selecting another listening mode.
