CONTROLS & CONNECTIONS

RCA INPUT & OUTPUT

RCA INPUT :
Connect preamp signal cables
from the source or the
headunit to RCA input

RCA OUTPUT :
Output RCA jack to another
amplifier.

POWER & PROTECT LED

Power LED :
Green-lit shows correct operation.

Protect LED :
Red-lit shows general malfunction,
faulty connection, thermal overload,
speaker short protection.

GAIN ( 6V ~ 0.2V )

Used to reach maximum amplifier
power by matching the output
voltage of with a wide variety of
the headunits

Control the high pass frequency for
the speaker outputs to eliminate
extreme low frequencies.
Subsonic is always on with a 24dB
per octave slope.

BASS BOOST ( 0 ~ 9dB )

The bass boost boosts frequency
centered at 45Hz.

REMOTE PORT

This port is for remote level control.
Plug remote control’s connector for
remote level control’s use.
Remote controls level from
the driver’s seat.

LOW PASS FILTER ( 35~250HZ @24dB )

Controls the low pass filter frequency
for the speaker output.
The Low pass filter is always on with
24dB per octave slope.

PHASE ( 0~180 DEGREE )SUBSONIC FILTER ( 10~50HZ @ 24dB )

Controls phase 0~180 degrees for fine
tunning your low end staging in your
vehicle or fully switching polarity
if inverting your woofers.

MASTER / SLAVE ( STRAPPABLE )

Output master / input slave connection makes 2 amplifiers strapped to 2ohm
Set Output master / input slave switch to output master position for Master amp
which is connected to headunit.
Set Output master / input slave switch to input slave position for Slave amplifier
Connect RCA cable from master amplifier to slave amplifier.
Output master / input slave connection impedance is 2ohm.
