Fine-tuning the adjustments of the subwoofer is a matter of personal preference. The
following guidelines should yield excellent results with a minimum of effort.
First, set the Volume and Crossover Frequency controls to a middle position (12 oclock).
Set the phase switch to 180°. Turn Auto Shut Off on. Turn Power on. Turn on the
system and play a selection with bass. If the subwoofer is not active, check all connections.
Check the phase of all speaker cables (plus-to-plus and minus-to-minus), if the speaker
inputs are used.
Play a familiar selection with a wide range of frequencies, preferably with rhythmic bass
(bass drum, electric bass, etc.).
Setting Volume: Select a level so that the level of bass matches the level of the main
speakers (fig.5).The contribution of the subwoofer should not in any way dominate the
frequency balance.
SET-UP
The subwoofer should provide a firm,
clear foundation, making the system
larger and more potent. If the bass le-
vel is exaggerated, there may be risk of
overloading the subwoofer and the
critical midrange may sound veiled and
recessed. Too much bass can be worse
than no subwoofer at all, so proceed with
care!
Selecting Crossover Frequency:
When the correct level is set, it is time
to experiment with an equally important
characteristic, the transition between the
subwoofer and the main speakers (fig.
6). While listening to an appropriate
selection, adjust Crossover Frequency
until the subwoofer blends seamlessly
with the main speakers. It may be
necessary to make additional Volume
adjustments as you seek out the ideal
crossover frequency.
