No sound – power indicator is lit
1.Check the Auto/on switch. If the auto/on switch is in the auto position, there
must be an audio signal present for the amplifier to work.
2. Check the audio cable from your audio/video receiver. If necessary, try a dif-
ferent cable.
Frequency Control Doesn’t Seem to Work
Check to see if you connected your receiver to the RSL Speedwoofer
’s
LFE in-
put (this is preferred in home theater installations). If so, your receiver’s crossover is
being used rather than your Speedwoofer’s, resulting in deactivation of your Speed-
woofer’s frequency control.
Hum
Hum can be caused by a variety of sources. We have listed a few common
sources and solutions.
1.A poorly shielded or defective audio cable from your receiver to the subwoofer
can create hum. Try replacing the cable and see if the hum goes away.
2. Excessively long audio cables can be another cause. If you have to use a ca-
ble longer than 20 feet, you may need to use a line driver (available from Audio/
Video dealers).
3. Hum can also be caused if an audio cable is routed near interference-
producing appliances or other AC devices and power cords. Try re-routing the
audio cable to see if the hum vanishes.
4. Sometimes you can reduce hum by increasing the subwoofer output of your
receiver and decreasing the volume of the subwoofer itself (consult your re-
ceiver’s manual).
5. Try plugging your subwoofer’s AC cord into the same circuit as your A/V re-
ceiver.
6. Turn off the subwoofer and disconnect the RCA cable from the input(s). Turn
on the subwoofer. If there’s no hum, then you have a ground loop. This is not the
fault of the subwoofer, but the electrical relationship of the subwoofer to the
other components in your system. The solution is to purchase an inexpensive
ground loop isolator, which is easy to find online. The RCA cable carrying the
signalwill plug in to it and the output of the isolator will plug into the subwoofer’s
input.
