Cleaning Your Dominion; Troubleshooting - JL Audio DOMINION d108 Bedienungsanleitung

CLEANING YOUR DOMINION™

Dust your Dominion™subwoofer's cabinet using a clean, soft microfiber cloth
or feather duster. Microfiber cloths are commonly available where automotive
detailing supplies are sold.
Gloss-Black models:
Light smudges can generally be wiped off with a clean microfiber cloth. For more
stubborn smudges, polish and protect the finish using a high-quality automotive
wax and a microfiber cloth, both available wherever automotive detailing
supplies are sold.
Vinyl-Veneer models:
Light smudges can generally be wiped off with a clean microfiber cloth.
For more stubborn stains, clean the cabinet's surface with a damp cloth.
Never use a polish that contains harsh solvents or abrasives, as these may
permanently damage the finish. Never use furniture polish or any oil-based
product on your Dominion™. Never use solvents or aggressive cleaning agents on
your Dominion™. When in doubt, test the cleaning product on the underside of
the cabinet and let it sit for several days before committing to its use on visible
portions of the cabinet.

TROUBLESHOOTING

No sound from subwoofer.
1. Verify that your Dominion™ is plugged in and that the control panel LED is green.
Remember that the Dominion™ only turns "on" if audio signals are present on the
sub's inputs. If the Dominion™ will not power up (no red or green LED), check the
circuit breaker that feeds its outlet or the AC power cord. If your AC outlet has
power but the LEDs still do not come on, you may need to inspect/replace the
main power fuse. Refer to the "Main Fuse Holder" section on the next page.
2. Verify that your receiver's subwoofer settings have not changed.
3. If your other speakers play, but the Dominion™ does not, try changing the
cable that connects the Dominion™ to the system.
4. If the problem persists, call your Authorized JL Audio Retailer or JL Audio
Technical Support for assistance.
The bass level has changed.
Make sure your level settings on the Dominion™ "Master Level" knob and in your
receiver/preamp/processor have not changed.
Hums or other unusual noises from your subwoofer
1. See discussion of "Grounded/Isolated" switch on page 17 of this manual,
especially if any upstream components, cables, etc., have recently changed.
2. Turn off the subwoofer, disconnect all its input and output signal cables; then
turn the subwoofer back on. If the noise disappears, the noise is being caused
elsewhere in your system.
