Features

1. Power status Led
This bi-color LED glows green when power
is on and no problems are present. lf one of
the protection circuits comes on, it will
change to red.
2. 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.
3. Auto Turn On
The auto power on (ON/OFF) is for high
level (speaker-level) connections. When
the switch is in the "ON" position, the
subwoofer auto power on when there is
signal input. If the amplifierdetect no signal
input, the amplifier will auto turn off. lf you
prefer to use the remote turn on/off connec-
tion, set the switch in the off position.
Note: Please connect the remote terminal
to the remote output of head unit as Fig.4.
When you turn on/off the head unit a receipt
pulse can be heard from the subwoofer.

4. Low Pass Filter
This control permits you define the frequen-
cy range you want the subwoofer amplifier
to receive. The subwoofer will reproduce all
sound BELOW the frequency you set.
Note: The low pass filter frequency can be
higher or lower than the visual scale
5. Bass Optimize
The Unique DLS Bass Optimize control
features a carefully Q-matched -6dB/+6dB
range to perfectly tune the bass response
when connecting to OEM factory radio. The
fixed bass boost in factory radios deteriora-
te bass musicality from additional subwoo-
fers because of the 50-60Hz bump in
factory radio output. With DLS Bass optimi-
ze control you can tune the low bass in your
car to an unrivalled natural bass.
