@ PHASE SHIFT
Use this switch to help compensate for time alignment problems
in the
system. Such problems usually result from having the subwoofer at a
different distance from the listenerthan the otherspeakers
in the system.
® INPUT GAIN CONTROL
Afteryou have installed your system, tum this control to minimum.
Turn the head unit on (and the subwoofer will turn on via the remote
connection). Tum the head unit volume to about 2/3 full level.
Slowly turn up the subwoofer input gain control until you hear a small
amount
of distortion. Then reduce the level until the distortion is
completely
gone. Leave the control at this setting.
@BASSBOOST
The bass boost feature will increase the sound level the bass frequencies.
®
LOW PASS FILTTER
This control permits you define the frequency range you want the subwoofer
amplifier to receive. The subwoofer will reproduce all sound BELOW the
frequency you set.
If the rest of yoursystem is weak on the mids , you may wish to set this
control relatively high.
If the midrange is well covered by the rest of your
system, you will probably want the subwoofer to only receive lower
frequency signal.
® REMOTE LEVEL CONTROL PORT
Attach the included remote level control to control the volume level
of the
subwoofer independently.
