settings: Loud, Deep, and Flat. See
Selecting EQ
Modes on page 17 for more information.

the display brightness. Available settings are Max,
Dim1, Dim2, and Off.

be adjusted from 40Hz to 150Hz. If the subwoofer is
connected via LFE, increase the low-pass filter until
“LFE” appears on the front display.
Adjusting for Best Performance
In an ideal audio system, the subwoofer works
“invisibly”, simply adding deep, loud bass without
calling attention to itself and blending seamlessly
with the main speakers so it appears that the
main speakers are making all the sound. The key
to seamless main speaker/subwoofer blending is
finding the perfect crossover frequency, equalization,
and phase settings for your system. The best place
to make those “set and forget” adjustments is from
your listening chair via the wireless remote. If your
receiver has built-in Audyssey or a similar auto setup/
room correction function, run that first. In most cases
that is all the adjustment you will need.
NOTE : The auto setup functions work best when the
subwoofer is connected to the LFE/subwoofer output.
1. Sit in your favorite listening position with remote
in hand.
2. Play a piece of music you are very familiar with
that has good deep bass content.
3. Adjust the volume up or down to taste. The bass
should have impact without sounding too “heavy.”
4. Using the Subwoofer Low-Pass Filter Guide on page
18 as a starting point, adjust the LP up or down until
there is a smooth transition between the main speaker
and subwoofer. Play a recording with male vocals and
string bass. Turn down the LP filter frequency until the
vocals sound rich but not “thick” or “chesty.” Turn it
up if the vocals sound “thin” or lacking in body.
5. Push the Phase button on the remote control to
adjust the Intelligent Phase Control setting on the
subwoofer. Then listen to how well the subwoofer
blends with your speaker system by how little you can
tell the difference of sound coming from your speakers
and subwoofer. This may also fix some unevenness in
the frequency response of your system. If you can’t
hear a difference between settings, it is recommended
that you leave the setting on 0 degrees.
