TROUBLESHOOTING
SYMPTOM SOLUTION
If there is no sound from any of the
speakers:
• Check that the source/receiver/SA1000 is on and playing.
• Check all wires and connections between the receiver/SA1000 and the speakers. Make sure all wires
are connected. Make sure none of the speaker wires are frayed, cut, punctured or touching each other.
• Review proper operation of your receiver/SA1000.
If there is no sound coming from one
speaker:
• Check the Balance control and channel output level settings on your receiver/SA1000.
• Check all wires and connections between the receiver/SA1000 and the speakers. Make sure all wires
are connected. Make sure none of the speaker wires are frayed, cut, punctured or touching each other.
In multichannel applications, make sure that your receiver/processor has been configured to enable all
channels that you are using.
If there is low (or no) bass output: • Make sure the connections to the speaker inputs have the correct polarity (+ and –). If you are using
two B28W subwoofers, try inverting the polarity on one subwoofer.
• In surround modes, make sure your receiver/ processor is correctly configured. Make sure the
subwoofer output of the receiver/processor has been enabled. See your receiver/ processor’s owner’s
manual for further information on correct speaker configuration in surround modes.
If the system plays at low volumes but
shuts off as volume is increased:
• Check all wires and connections between the receiver/SA1000 and all of the speakers. Make sure all
wires are connected. Make sure none of the speaker wires are frayed, cut, punctured or touching each
other. A shorting satellite speaker could shut the receiver down.
• If more than one pair of main speakers is being used, check the minimum-impedance requirements of
your receiver.
If you are hearing midrange frequencies
(such as vocals) through the subwoofer:
• Adjust the crossover frequency on your Revel SA1000 amplifier to a lower value.

loudspeakers feature custom-designed transducers and high quality network components featuring high-order filters with steep cutoffs
that reduce the potential of damage to individual speaker drivers and help the loudspeakers maintain their performance even under extreme operating
conditions. However, all loudspeakers have limits when it comes to continuous playback. To extend these limits, avoid playback at volume levels that
result in distorted or strained sound.
