roubleshooting

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-2 rear panel. Check to make sure that the DC-2 rear
panel power switch is ON.

No audio

Check the Status menu (under DISPLAY ADJUST: ON-SCREEN or
FRONT PANEL menu — or press and hold Record/Zone 2 on the
remote and press OSD ON) to verify that audio is being received.

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-2 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-2. (Check the Status menu
by pressing and holding Record/Zone 2 on the remote, then pressing
OSD ON. This menu will display input level meters and sample rate, if
applicable.)
Increase VOLUME using the remote control and check Front/Back and
Left/Right BALANCE.

Check the DC-2

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-2 are operational.

Remember that the DC-2 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-2 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, or when the Status menu is displayed.

No Video

Make sure that video cables (particularly S-Video cables) are fully
inserted and that the appropriate connector is assigned to the VIDEO IN
parameter in the Input Configuration menu.
