With high volume levels of certain types of signals, the subwoofer may be audibly strained. If you
hear the subwoofer "breaking-up" or distorting, turn your receiver's volume level down.
If you have any problems or questions please contact your PINNACLE
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.
Too Much Bass - Check: subwoofer volume/phase/frequency controls; receiver bass/loudness controls;
program material; move subwoofer further out of corner or away from wall.
Too Little Bass - Check: subwoofer volume/frequency/phase 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 phono cable you may want to try using a cable splitter (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 post caps 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 phono connecting cable. Try to separate phono 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 either connecting its powercord to a switched power outlet on the
back of your receiver (if it has them) or by using a Remote Controlled Switched Outlet like Radio Shack part
#61-2667.
