TROUBLESHOOTING:
No Sound only from Subwoofer - Please note that this subwoofer has a thermal protection feature which
will shut off its amplifier if it gets too hot; it will turn itself back on when it has cooled sufficiently. Otherwise:
Check subwoofer power / volume settings and all connections. Ensure that the center channel mode on
the receiver is in the NORMAL or SMALL position. If you have connected the subwoofer via RCA cable
and if your receiver has a subwoofer on/off or variable subwoofer output level control, ensure that the
subwoofer option is turned on and that the output level is at maximum. Make sure the RCA cable is
connected to the receiver's subwoofer output and not the subwoofer input jack that some receivers have.
If the problem persists, refer to the TO OBTAIN SERVICE section of your warranty at the end of this
manual.
No Sound only from Left and Right Front Speakers - Check all connections. Ensure that your receiver's
speaker channel A or B is switched on. Note: You must connect your speakers to your receiver's speaker
outputs if you connected the subwoofer via the LINE INPUT(s).
Too Much Bass - Check: subwoofer volume / phase / crossover control positions; receiver bass /
loudness controls; program material; move subwoofer further out of corner or away from wall.
Too Little Bass - Check: subwoofer volume / phase / crossover control positions; all speaker wire phase
(+ to +, - to -); receiver tone controls; program material; ensure that the center channel mode on the
receiver is in the NORMAL or SMALL position. If your receiver has a variable subwoofer output level
control, ensure that the output level is at maximum. Try moving the subwoofer further into a corner or
towards the wall. If you have connected the subwoofer via a single RCA cable you may want to try using
a cable splitter (such as Radio Shack part #42-2535). This will allow you to use both line inputs which will
increase the input signal strength to the subwoofer.
Rattling Noise: Tighten the binding posts on the sub's speaker level inputs & outputs. Check all four of
the Solid Brass Isolation Cones to ensure they are making solid contact with the floor.
Hum: Check for faulty RCA connecting cable. Try to separate RCA cables from power cords (they can
induce hum into the system). If that doesn't work we recommend you turn off your subwoofer when it is
not in use. This is most easily accomplished by connecting its powercord to a switched power outlet.
