TROUBLESHOOTING
No sound from subwoofer.
1. Verify that Fathom is plugged in, turned "ON" & that front panel lights are "ON". If
the Fathom will not power up, check the circuit breaker that feeds its outlet.
2. Test subwoofer using DEMO button on front panel – if sub emits demo tones the
subwoofer's internal circuitry is fi ne and an input problem is likely. Check the input
cable connections at the Fathom and at the receiver/preamp/processor.
3. Verify that your receiver's subwoofer settings have not changed
4. If your other speakers play, but the Fathom does not, try changing the cable that
connects the Fathom to the system.
5. If the problem persists, call your dealer or JL Audio Technical Support
for assistance.
Th e bass level has changed.
1. Make sure your level settings (on the Fathom and in your receiver/preamp/
processor) have not changed.
2. If you are using the Fathom's "Master Level" knob to set the subwoofer level,
confi rm that the "Level Mode" switch is set to "Variable".
3. Verify the position of the ELF Trim knob.
Hums or other unusual noises from your Fathom
1. See Input Mode discussion on page 20 of this manual, especially if any upstream
components, cables, etc., have recently changed.
2. Turn off the Fathom, disconnect all its input and output signal cables, turn the
Fathom back on. If the noise disappears, the noise is being caused elsewhere in
your system.
Bass sounds "muddy" or "too heavy".
1. Try decreasing the 28 Hertz level using the "e.l.f. trim" control. Muddy bass
can sometimes be caused by too much low frequency output in a moderately
sized room.
2. Decrease the overall subwoofer level.
3. Verify your receiver's subwoofer settings.
4. Try a diff erent subwoofer or main listening seat location. Changing one or the
other can have a HUGE eff ect on how your system sounds. See the placement
discussion on pages 6-10 of this manual.
A.R.O. Calibration attempt gives fast blinking Calibrate light
1. Be sure that the included JL Audio Microphone is properly plugged into the
front panel jack. Calibration will ONLY proceed with the JL Audio microphone
connected. Connecting any other mic will cause the calibration to fail.
2. If calibration fails with the JL Audio microphone properly connected, try running
calibration again with the microphone placed ~ 6 feet away from the f110. If
calibration fails again, the microphone or microphone cable is bad and will need to
be replaced. Contact JL Audio Customer Service.
Your Fathom is clearly audible outside of your house.
1. Revisit the "Master Level" setting on your Fathom(s) or your home theater receiver/
preamp/processor.
2. Inquire with your JL Audio dealer about noise isolation strategies.
3. Move the Fathom away from windows.
