If you have any trouble using the A-9377, look for a solution here. If you cannot resolve the issue yourself, contact your Onkyo dealer.

Power

Cannot turn on the A-9377.

•Make sure that the power cord is properly plugged into the wall outlet.

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

The SPEAKERS A and B indicators are both ﬂashing.

•The amp protection circuit has been activated. Set the POWER switch to OFF immediately, remove the power cord from the wall outlet, and contact your Onkyo dealer.

Audio

There’s no sound or it’s very quiet.

•Make sure that all audio plugs are pushed in all the way (page 12).

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

•Make sure that the polarity of the speaker cables is correct and that the bare wires are in contact with the metal part of each speaker terminal (page 11).

•Make sure that the correct input source is selected (page 16).

•If the MUTING indicator is ﬂashing, press the remote controller’s [MUTING] button to unmute the A-9377 (page 16).

•Make sure that none of the cables are bent, twisted, or damaged.

•If your turntable uses an MC type cartridge, you must use an MC head amp or MC transformer (page 12).

•Make sure the SPEAKERS selector is set correctly. If it’s set to OFF, no speakers will output sound (page 15).

Noise can be heard.

•Using cable ties to bundle audio cables with power cords, speaker cables, and so on may degrade the audio performance, so do not bundle them together.

•An audio cable may be picking up interference. Try repositioning your cables.

The tone controls have no effect.

•If the TONE/DIRECT indicator is on, the Direct func- tion is on and the tone controls have no effect. Press the [TONE/DIRECT] button to turn the function off. The TONE/DIRECT indicator will go off (page 16).

Remote Controller

The remote controller doesn’t work.

•Make sure that the batteries are installed with the cor- rect polarity (page 10).

•Try installing new batteries. Do not mix different types of batteries or old and new batteries (page 10).

•Make sure that the remote controller is not too far away from the A-9377 and that there’s no obstruction between the remote controller and the A-9377’s remote control sensor (page 10).

•Make sure that the A-9377 is not subjected to direct sunshine or inverter-type ﬂorescent lights. Relocate if necessary (page 10).

•If the A-9377 is installed in a rack or cabinet with col- ored glass doors, the remote controller may not work reliably when the doors are closed (page 10).

Cannot control other components?

•If it’s an Onkyo component, make sure that the cable and analog audio cable are connected properly.

Connecting only an cable will not work. (page 14)

The A-9377 contains a microcomputer for signal processing and control functions. In very rare situations, severe interference, noise from an external source, or static electricity may cause it to lock up. In the unlikely event that this happens, unplug the power cord from the wall outlet, wait at least ten seconds, and then plug it back in again.

Onkyo is not responsible for damages (such as CD rental fees) due to unsuccessful recordings caused by the unit’s malfunction. Before you record important data, make sure that the mate- rial will be recorded correctly.
