1POWER TERMINALS
2PHASE 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 listener than the other speakers in the system.
3LOW PASS FILTER
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 your system 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.
4BASS BOOST
The bass boost feature will increase the sound level in the bass frequencies.
5INPUT GAIN CONTROL
After you have installed your system, turn this control to minimum
Turn the head unit on (and the subwoofer will turn on via the remote connection). Turn 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.
6FUSE
The fuse in the upper socket is the fuse which provides protection for the circuitry. The fuse is rated at 25A. Do not use a fuse with a different value and NEVER replace the fuse with a wire or coin.
