A. POWER STATUS LED
This bi-color LED glows green when power is
on and no problems are present. If one of the
protection circuits comes on, it will change to
red.
B. 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.
C. AUTO POWER ON
The AUTO POWER ON(ON/OFF) is for high level
(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 detected no signal input, the
amplifier will auto turn off, If you prefer to use
the remote turn on/off connection, the switch
is in the OFF position.
Note: Please connect the remote terminal to
the remote output of head unit as Fig.4 when
you hear the unit turn ON/OFF POP noise from
the subwoofer.
D. LOW 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.
Note: The low pass filter frequency can be
higher or lower than the standard. There have
+/-20% tolerance.
E. BASS BOOST
The BASS BOOST feature will increase the
sound level in the bass frequencies.
F. INPUT 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. Level the
control at this setting.
G. REMOTE LEVEL CONTROL PORT
Attach the included remote level control to
control the volume level of the subwooer
independently.
H. 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 subwoofer. Use the supplied
cable and wire harness and connect the
outputs properly as shown in the connection
diagram in this manual.
I. LOW LEVEL RCA INPUTS
Low level inputs are the recommended way
to introduce the audio signal to the subwoof-
er if RCA outputs 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.
