MartinLogan MLT-2 user manual Troubleshooting, Speaker No Output, SUBWOOFER No Output, Muddy Bass

Will my electric bill go ‘sky high’ by leaving my subwoofer plugged in all the time?

No. The MLT-2 5.1 subwoofer, when the power switch is set to ‘Auto On’, will draw about 12 watts when idle and only 12 watts in standby mode.

Should I unplug my subwoofer during a thunderstorm?

Yes, or before. It’s a good idea to disconnect all of your audio/video components during stormy weather.

Troubleshooting

•Check that all your system components are turned on.

SUBWOOFER

No Output

•Check that all your system components are turned on.

•Check that the power switch is set to ‘Auto On’.

•Check your wires and connections.

•Check all interconnecting cables.

•Make sure the level control is not turned down.

•Turn off and unplug the MLT-2 subwoofer and check the fuse near the AC power cord receptacle on the back. If the fuse has blown, replace the bad fuse with a matching fuse.

•If the problem persists, contact your dealer.

Muddy Bass

•Check placement. Try moving the subwoofer closer to the front and side walls.

•Decrease the level.

•Check your processor setup.

•If the problem persists, contact your dealer.

Hums or Unusual Sounds

•Turn the MLT-2 subwoofer off, unplug all signal inputs, turn the MLT-2 subwoofer back on and turn up the level. If the problem disappears, the hum is originating elsewhere in your system.

•Connect the MLT-2 subwoofer AC connection to the same AC circuit as the pre amp.

•If the problem persists, contact your Dealer.
