CD POWER ON LED INDICATOR
@ 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 listener than the other speakers in the system.
® INPUT GAIN CONTROL
After you 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 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.
®REMOTE LEVEL CONTROL PORT
Attach the included remote level control to control the volume level of the subwoofer independently.

CDLOW LEVEL RCA INPUTS
Low level inputs are the recommended way to introduce the audio signal to the subwoofer if RCA outputs are present on your head unit or other signal source (such as a sound processor).
@HIGH LEVEL (speaker level) INPUTS
If your head unit does not have RCA outputs, you can use the speaker outputs for the audio source for the AQTB8. Use the supplied cable
and connect the outputs properly as shown in the connection diagram in this manual .
®FUSE
The fuse is rated at 15A. Do not use a fuse with a different value and NEVER replace the fuse with a wire or coin.
