OPERATION
Crossover Adjustments
High-Pass Control
• This control is only active if you are using the hook-up
method described in detail on page 8, Figure 3. The
High-Pass control determines the frequency at which the
main speakers will start reproducing sounds. If your main
speakers can comfortably reproduce some low-frequency
sounds, also set this control to a lower frequency setting,
between 50Hz – 100Hz. This will concentrate the
subwoofer’s efforts to the ultradeep bass sounds, while your
main speakers continue to reproduce the mid-bass
information. If you are using smaller bookshelf speakers
that do not extend to the lower bass frequencies, set the
high-pass crossover control to a higher setting, between
125Hz – 180Hz. With this setting, your main speakers will
not have the burden of reproducing any low-frequency
sounds.
Final adjustment and blending of the low-pass and
high-pass controls may evolve over several listening
sessions. A good starting point would be to set both the low-
and high-pass controls to the same frequency and adjust
from that point.
Low-Pass Control
The Low-Pass control determines the highest frequency at
which the subwoofer reproduces sounds. If your main
speakers can comfortably reproduce some low-frequency
sounds, set this control to a lower frequency setting,
between 50Hz – 100Hz. This will concentrate the
subwoofer’s efforts on the ultradeep bass sounds required
by today’s films and music. If you are using smaller
bookshelf speakers that do not extend to the lower bass
frequencies, set the low-pass crossover control to a higher
setting, between 120Hz – 180Hz.
Phase
Phase Control
The Phase Control determines whether the subwoofer
speaker’s piston-like action moves in and out with the main
speakers, 0° , or opposite the main speakers, 180° . There is
no correct or incorrect setting. Proper phase adjustment
depends on several variables such as room size, subwoofer
placement and listener position. Adjust the phase switch to
maximize bass output at the listening position.
Remember, every system, room and listener is different.
There are no right or wrong settings; any setting you choose
will result in excellent performance. Should you decide to
fine-tune your system for optimum performance, be patient
and trust your ears. It will be worth the effort involved to fully
“tweak” your system.
