Adjustment procedure
Set the LEVEL control to minimum position, the FREQUENCY cutoff control set to 180 Hz, the
PHASE control set to 0°. The first test is suitable e.g. playing a male voice with a normal depth
share. Use a convenient medium volume.
Set the POWER switch of your FUSION to ON or AUTO.
Slowly turn up the LEVEL control of FUSION until the total volume of the bass response is
getting elevated by the subwoofer. At first, subwoofer and stereo speakers work together in the
upper bass range, though the bass level must be a little elevated, normally.
In case the bass of the voice drops considerably when turning up the LEVEL control; change the
PHASE control to the 180° position and start the level adjustment from the beginning.
Next, turn the FREQUENCY control slowly down from 180 Hz to a lower frequency, as much as
that you hear the upper bass range elevation does no more appear. The subwoofer now only
works at a frequency range below the stereo speakers.
Dependant from the positioning and type of the stereo speakers, adjusting the PHASE control can
even improve the acoustical co-operation with the subwoofer. If you cannot hear any improvement
after changing the PHASE control setting keep it in the initial position 0° (resp. 180°).
Even if not every music playback is optimally played after the initial setting, a significant extension
of the bass response without excessively booming can be achieved by repeated fine re-
adjustments. Try it with some patience and use various audio tracks for testing. Probably a
different placement of the subwoofer could make a big difference, nearer to or farer from the
listening position.
The setting of a subwoofer is considered optimal, if playback without the subwoofer (OFF) sounds
almost exactly like with the subwoofer (ON or AUTO) - while without the subwoofer, just the depth
or darkness of the bass sound image is missing.
When the adjustment is accompanied by special acoustical measurements, the subwoofer setting
results might match with the stereo speakers even more exactly. In spite of that, a subjective
altering of the settings is often beneficial to achieve a particularly coherent interaction between the
speakers.
