Troubleshooting

If you have any trouble using the A-933, look for a solution here. If you can’t resolve the issue yourself, contact your Onkyo dealer.

Power

Can’t turn on the A-933.

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

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

•By default, pressing the A-933’s [STANDBY/ON] button once does not turn on all of the system components. You need to press the remote controller’s [ON] button again. Alternatively, you can set the A-933 so that all components

do turn on simultaneously (page 17).

The STANDBY indicator is flashing red.

•The amp protection circuit has been activated. Remove the power cord from the wall outlet immediately and contact your Onkyo dealer.

Audio

There’s no sound or it’s very quiet.

•When the A-933 is used as a power amplifier (MAIN IN indicator lights up blue), the sound from components con- nected to the preamp are output. To output the sound from a component that’s connected to the A-933, or to use the A-933 as a preamp, press the [MAIN IN] button for 3 seconds until the MAIN IN indicator goes off.

•Make sure that all audio plugs are pushed in all the way (page 11).

•Make sure that the inputs and outputs of all components 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 12).

•Make sure that the correct input source is selected (page 17).

•If the STANDBY indicator is flashing green, press the remote controller’s [MUTING] button to unmute the A-933 (page 18).

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

•Make sure that SPEAKERS A or B are selected. When only SPEAKERS A is selected (A indicator on), speakers connected to the SPEAKERS A terminals, and a connected subwoofer will output sound. When only SPEAKERS B is selected (B indicator on), speakers connected to the SPEAKERS B terminals, and a connected subwoofer will output sound.

•To use a turntable with a moving-coil (MC) type cartridge, you need a commercially available MC phono preamp (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 perfor- mance, so don’t bundle them together.

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

The tone controls don’t work.

•If the TONE/DIRECT indicator is green, Direct mode is selected and the tone controls have no effect. Press the [TONE/DIRECT] button to select Tone mode. The TONE/DIRECT indicator will turn red (page 18).

Remote Controller

The remote controller doesn’t work.

•Make sure that the batteries are installed with the correct polarity (page 9).

•Install new batteries. Don’t mix different types of batteries or old and new batteries (page 9).

•Make sure that the remote controller is not too far away from the A-933 and that there’s no obstruction between the remote controller and the A-933’s remote control sensor (page 9).

•Make sure that the A-933 is not subjected to direct sunshine or inverter-type florescent lights. Relocate if necessary (page 9).

•If the A-933 is installed in a rack or cabinet with colored glass doors, the remote controller may not work reliably when the doors are closed (page 9).

Can’t 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 won’t work.
