manual receiver setup
Ensure subwoofer is set to ON or YES in your
receiver setup (Refer to your receiver/processor
manual for more information).
Use default subwoofer channel level setting on
your receiver.
On your receiver select desired crossover
frequency/low pass setting. As a guide use the
80Hz setting.
If your speakers are small (bass driver is
smaller than 5 1/4”) use a higher setting
(100Hz,120Hz,150Hz) to send more of
the bass information to your subwoofer.
Consult your receiver manual for further
bass management options and settings.
manual subwoofer calibration
When using the subwoofer in a home theatre
installation it is beneficial to listen to movies
with extended periods of low bass (explosions,
rumbles etc). This will allow you to evaluate
the ‘impact’ and ‘depth’ of your subwoofer. It
is also beneficial to select music that is familiar
to you when carrying out listening tests. As a
suggestion play clean unprocessed recordings
that use double bass, bass guitar, cellos, organ
or kick drum etc. that cover a wide bass
spectrum.
Begin by playing the movie/music and slowly
adjust the volume setting on the subwoofer to
your desired level.
For final tweaking of your subwoofer
level you may wish to sit in the primary
listening position and adjust the
subwoofer channel level using your
receiver’s remote control. (Refer to your
receiver’s manual for more information)
Now set the phase setting. The correct phase
setting will produce the most bass. You may
