OPERATION

After you have connected your subwoofer, adjusted it for proper operation with the
rest of your system, and experimented to find the best location for it, it’s time to sit
back and enjoy it.  As you do, here are some hints for getting the most out of your
subwoofer.

A) The subwoofer’s level control is designed to adjust the balance between your
subwoofer and main stereo speakers and should not be used as a substitute for
the bass or loudness controls on your amplifier or receiver.  If more bass is
desired, advance the bass or loudness controls on your main amplifier or receiver.

B) Your subwoofer’s auto turn-on-turn-off feature allows “set it and forget it”
operation by keeping the electronics in a standby mode until a signal is detected,
which turns the amplifier on instantly.  When there is no signal present after a few
minutes, the electronics will again shut down to the standby mode.  We do
suggest that you turn the subwoofer off by its power switch if it is to be unused for
an extended period of time. For additional protection against damage from
lightning, we recommend unplugging the line cord.

C) The tone controls on your preamplifier, receiver, or amplifier should be used
with caution and care.  Excessive boost in certain frequency ranges can cause
heavy demands on amplifier and loudspeaker components resulting in
overheating, distortion, mechanical overload, and premature failure.

CARE AND CLEANING

Your subwoofer is finished in a durable vinyl and may be wiped clean with a damp
cloth as needed when the power switch is turned off.
