DC-1 Digital Controller

Troubleshooting 4 Troubleshooting

If you encounter a problem, please review the items in the following	Troubleshooting
checklist. Also be sure to thoroughly check all other connected components

such as speakers, receiver/amplifier/preamp, VCR, TV, CD player, etc.

Problem

Possible Cause and Solution

Power does not come on

No audio

Remote control not working

No output

Center Channel only plays

Muffled sound in L&R channels

Center channel sound muffled

No Input Level Meters

Check line cord to ensure good connection to the AC outlet and to the receptacle on the DC-1 rear panel. Check to make sure that the DC-1 rear panel power switch is ON.

Check input and output connections. They may be reversed relative to the IN and OUT jacks of your receiver/amplifier/preamp or other source.

Check batteries to be certain that they are inserted correctly with proper polarity. Make sure that the infrared sensor on the DC-1 front panel is not obstructed. See "If all else fails..." on the following page.

Make sure that signal is coming into the DC-1. Increase VOLUME using the remote control and check Front/Back and Left/Right BALANCE.

Check the DC-1 MUTE controls to make sure they are not engaged.

Check all other equipment settings and connections and verify that the amplifiers being fed by the DC-1 are operational.

Remember that the DC-1 mutes the output to any speakers which are not configured in the Setup menu. If speakers are added to (or removed from) your system, the Speaker Configuration menu must be altered accordingly.

Check to see if your HiFi VCR has dropped out of tracking — readjust.

Your VCR Stereo/Mono/L-R switch may be in the wrong position — set it to Stereo.

When no center channel is used, CENTER must be configured for NONE in the Setup Speaker Configuration menu.

The center channel amp may be connected to the subwoofer jack on the DC-1 rear panel. Reconnect to Center Output jack.

The meters will only appear when adjusting the Gain parameter of a selected, active input.
