PANEL CONTROLS AND FEATURES
A. POWER STATUS LED
This bi-coloured LED glows green when power is on
and no problems are detected. If one of the
protection circuits come on, the LED will glow 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 dierent 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 a signal input. If the amplifier detected
no signal input, the amplifier will auto turn o. If you
prefer to use the remote turn on/o connection, the
switch is in the OFF position.
(NOTE: Please connect the remote terminal to the
remote output of head unit (See Fig 4) when you hear
the unit turn ON/OFF POP noise from the subwoofer).
D. LOW PASS FILTER
This control allows 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 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 subwoofer 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 dierent value and never
replace the fuse with a wire or coin.
K.POWER INPUT TERMINAL
