DC-1 Digital Controller

Troubleshooting

If you encounter a problem, please review the items in the following

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 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.

No audio Check input and output connections. They may be reversed relative to

the IN and OUT jacks of your receiver/amplifier/preamp or other

source.

Remote control not working 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.

No output 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.

Center Channel only plays 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.

Muffled sound in L&R channels When no center channel is used, CENTER must be configured for

NONE in the Setup Speaker Configuration menu.

Center channel sound muffled The center channel amp may be connected to the subwoofer jack on the

DC-1 rear panel. Reconnect to Center Output jack.

No Input Level Meters The meters will only appear when adjusting the Gain parameter of a

selected, active input.
