Adjust Gain
Turn your subwooferOs Level control up to the O5�position
(half way). If no sound emanates from the subwoofer,check the
AC-line cord and input cables.Are the connectors on the cables
making proper contact? Is the AC plug connected to a Olive�
receptacle? Has the Power button been pressed to the OOn�
position? Once you have confirmed that the subwoofer is active,
proceed by playing a CD, record or cassette. Use a selection that
has ample bass information.
Set the overall volume control of the preamplifier or stereo to a
comfortable level.Adjust the subwooferOs Level control until
you obtain a pleasing blend of bass. Bass response should not
overpower the room but rather be adjusted so there is a
harmonious blend across the entire musical range. Many
users have a tendency to set the subwoofer volume too loud,
adhering to the belief that a subwoofer is there to produce lots
of bass.This is not entirely true.A subwoofer is there to enhance
bass, extending the response of the entire system so the bass
can be felt as well as heard. However, overall balance must
be maintained or the music will not sound natural.An
experienced listener will set the volume of the subwoofer so its
impact on bass response is always there but never obtrusive.
Phase Control
The Phase switch determines whether the subwoofer
speakerOs piston-like action moves in and out with the main
speakers, 0u, or opposite the main speakers, 180u. 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.
