PANEL CONTROLS AND FEATURES

A. POWER STATUS LED
This bi-color LED glows green when power is on
and no problems are present. If one of the protect-
ion circuits comes on, it will change to red.
B. PHASE SHIFT
Use this switch to help compensate for time align-
ment problems in the system. Such problems usu-
ally result from having the subwoofer at a different
distance from the listener than the other speakers
in the system.
C. AUTO POWER ON
The AUTO POWER ON(ON/OFF) is for high le-
vel (speaker-level) connections. When the switch is
in the "ON" position, the subwoofer will AUTO
POWER ON when there is signal input. If the
amplifier detects no signal input, the amplifier will
auto power off. If you prefer to use the remote turn
on/off connection, leave switch in the "OFF" position.
Note: Please connect the remote terminal to the
remote output of head unit as Fig.5 when you
hear the unit turn ON/OFF POP noise from the
subwoofer.
D. LOW PASS FILTER
This control permits you to define the frequency
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 high-
er or lower than the standard.There is +/-20%
tolerance.
EF. INPUT GAIN CONTROL
After you have installed your system, turn this con-
trol to minimum.
D E F G I H J
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. Level the control at this setting.
G. REMOTE LEVEL CONTROL PORTAL
Attach the included remote level control to control
the volume level of the subwooer independently.
H. OUTPUT / HIGH LEVEL INPUT
The output / high level terminal permits for high-
level signal in (below part: HIGH LEVEL INPUT).
It also allows for the amplified signal to be sent to
your speakers system (above part: OUTPUT) for a
true 2.1 system.
Note: If you are using the RCA inputs (low level)
you must disconnect the high-level plug on the
cable beam in order to achieve the 2.1 system
(2x55W RMS). You must respect this order, if
not you might damage the product.
I. LOW LEVEL RCA INPUTS
Low level inputs are the recommended way to intro-
duce the audio signal to the subwoofer if RCA out-
puts are present on your head unit or other signal
source (such as a sound processor).
J. FUSE
Do not use a fuse with a different value and NEVER
replace the fuse with a wire or coin.
