TROUBLESHOOTING
No sound from subwoofer.
1. Verify that Gotham v2 is plugged in, turned "ON" & that front panel lights are
"ON". If the lights do not turn on, check the circuit breaker that feeds its outlet or
plug the Gotham v2 into another AC power outlet. If your AC outlet has power
but the lights still do not come on, you may need to inspect/replace the Gotham
v2's main power fuse. Refer to the "Main Fuse Holder" section on the next page.
2. Test the subwoofer by pressing the DEMO button on the front panel – if the sub
emits demo tones the subwoofer's internal circuitry is fine and an input problem
is likely. Check the input cable connections at the Gotham v2 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 Gotham v2 does not, try changing the cable
that connects the Gotham v2 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 Gotham v2 and in your receiver/preamp/
processor) have not changed.
2. If you are using the Gotham v2'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 Gotham v2
1. See Input Mode discussion on page 20 of this manual, especially if any upstream
components, cables, etc., have recently changed.
Turn off the Gotham v2, disconnect all its input and output signal cables,
2.
turn the Gotham v2 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 24 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 different 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.
