It is not recommended for use in DJ, pro-sound, or other high-duty-cycle applications. For home audio tabletop applications, use
the unit as it comes out of the box with the rubber feet and without the rack ears. In a custom home theater or studio where rack

3. Frequency

200Hz.WhenusingtheLeft/Rightinputs,thisadjustment
will allow you to properly integrate the subwoofer with the
satellite or main speakers. It is recommended to experiment
with different settings until the smoothest transition between
subwoofer and speakers is achieved.
4. Phase
Adjustable phase compensation from 0 to 180 degrees.
Helps the user correct improper phasing of the main speak-
ers or differing listening distances between the subwoofer
and mains, which can cause a poor acoustic summation
around the crossover point. In most situations the knob
should be left at 0 degrees, but for the advanced user it can
be set either by ear or with the aid of measurement instru-
ments.
5. EQ
The EQ adjustment knobs enable the user to custom-tailor

which can be used to add boost to the low-end of the re-
sponse, or can be used to cut out an excessively loud room
resonance. The freq. knob selects the frequency for the
lter,thebandwidthknobselectshowwideornarrowthe

and the level knob can be used to add up to 6dB of boost or
14 dB of cut.
