FREQUENCY ADJUSTMENT
With a surround processor
When using the subwoofer output of a surround processor,
set the subwoofer's frequency control fully clockwise.
Your surround processor has a variety of adjustments to
optimize the sound based on the speakers' capabilities and
placement. These adjustments vary by processor, so refer to
your processor's manual for instructions specific to your
equipment. Set your main, center, and surround settings to
'SMALL", with subwoofer 'ON'. Set the volume control
to its centered position and use the processor's
level adjustments to balance the system. You may then
use the remote control of the subwoofer to quickly fine-
tune the subwoofer level for different program material.
With no surround processor:
When using a source component that does not have a dedi¬
cated subwoofer output you must use the crossover fre¬
quency adjustment of the subwoofer to match the low fre
quency capability of your main speakers. Determine the final
settings by ear
speakers to determine the best setting to use as a starting
point for this control. You should start from the low frequen¬
cy limit of your main speakers. For most small satellite-
speakers typical of home theater systems, this will be
between 65 - 100Hz. Refer to the specifications of your main
Room characteristics are very strong in this
frequency range, so don't be surprised if the final settings
you like are far from the starting point.
Use the volume control to balance the system.
Listen to a variety of program material with good bass
to fine-tune the various settings. In a properly set up system
the bass should be smooth and clear, but from the listening
position it should sound as if it is coming from the main
speakers, not from a separate subwoofer. If is is not the
case, your subwoofer may be too loud, or the crossover fre¬
quency may be set too high.
