TROUBLESHOOTING

No sound from subwoofer.
1. Verify that E-Sub is plugged in, turned "ON" & that the top-panel LED is green.
If the E-Sub will not power up, check the circuit breaker that feeds its outlet, or
the AC power cord.
2. Verify that your receiver's subwoofer settings have not changed.
If your other speakers play, but the E-Sub does not, try changing the cable

that connects the E-Sub to the system.
4. If the problem persists, call your dealer or JL Audio Technical Support for
assistance.
The bass level has changed.
Make sure your level settings on the E-Sub's "Master Level" knob and in your
receiver/preamp/processor have not changed.
Hums or other unusual noises from your E-Sub
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 E-Sub, disconnect all its input and output signal cables; then
turn the E-Sub back on. If the noise disappears, the noise is being caused
elsewhere in your system.
Bass sounds "muddy" or "too heavy".
1. Decrease the overall subwoofer level.
2. Verify your receiver's subwoofer settings.
3. Try a different subwoofer location or main listening seat location. Changing
one or the other can have a HUGE effect on how your system sounds. See the
placement discussion on pages 6-10 of this manual.
Your E-Sub is clearly audible outside of your house.
1. Revisit the "Master Level" setting on your E-Sub(s) or your home theater
receiver/preamp/processor.
2. Inquire with your JL Audio dealer about noise isolation strategies.
Move the E-Sub away from windows.
3.
Angry neighbors knocking at your door.
Invite them in and offer them a beverage.
