MC-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 compo-

nents 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 MC-1 rear panel. Check to make sure that the MC-1

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 MC-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 MC-1. (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 MC-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 MC-1 are operational.

Remember that the MC-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

MC-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, or when the Status menu is displayed.
