Troubleshooting

No sound from subwoofer.

1.Verify that Fathom IWS amp is plugged in, turned “ON” & that front panel lights are “ON”. If the Fathom IWS amp will not power up, check the circuit breaker that feeds its outlet.

2.Test subwoofer using DEMO button on front panel of amp– if sub emits demo tones the subwoofer’s internal circuitry is fine and an input problem is likely. Check the input cable connections at the Fathom IWS amp 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 IWS does not, try changing the cable that connects the Fathom IWS to the system.

5.If the problem persists, call your dealer or JL Audio Technical Support for assistance.

The bass level has changed.

1.Make sure your level settings (on the Fathom IWS amp and in your receiver/ preamp/processor) have not changed.

2.If you are using the Fathom IWS’s “Master Level” knob to set the subwoofer level, confirm 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 IWS

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 IWS, disconnect all its input and output signal cables, turn the Fathom IWS back on. If the noise disappears, the noise is being caused elsewhere in your system - reconnect cables one at a time to help locate the problem.

Bass sounds “muddy” or “too heavy”.

1.Try decreasing the 23 Hertz level using the ELF 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 different main listening seat location. Changing your seating location can have a HUGE effect 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 Fathom IWS speaker enclosure. If calibration fails again, the microphone or microphone cable is bad and will need to be replaced. Contact JL Audio Customer Service.
