RCA JACK INPUT
Low Level Rca Input will accept the signal from the output of
head units. Plug in Rca jack cables from the head unit.
GAIN CONTROL ( 6V ~ 0.2V )
The gain control adjusts the gain level. so that this is used to
match the signal level of different headunits.
HIGH PASS FILTER ( 50Hz ~ 5KHz @ 12dB / Oct slope )
The crossover features a steep 12dB oct slope
Linkwitz-Riley high pass crossover ensuring that only
the highest frequencies are reproduced by the amplifier.
X-OVER SLECTOR SWITCH ( HPF/FULL/LP-BP )
Selected x-over is in effective.
LOW PASS FILTER ( 50Hz ~ 5KHz @ 12dB / Oct slope )
The crossover features a steep 12dB oct slope
Linkwitz-Riley low pass crossover ensuring that only
the lowest frequencies are reproduced by the amplifier.
BASS BOOST ( 0 ~ 18dB @ 45Hz )
It adjusts for up to 9dB of additional gain at that frequency.
REMOTE CONTROL PORT
Plug remote controller to this port for remote gain control
Remote control can be mounted around driver’s seat for easy
access.
MODE SWITCH ( CH2 / CH4 )
Mode switch selects how many Rca jack input is used.
RCA JACK OUTPUT
The preamp output is a full range signal mixed from both input
channels. Use this signal to feed a secondary full range
amplifier in the system.
POWER & PROTECTION LED
Power LED, Green-lit shows correct operation.
Protect LED, RED-lits shows general malfunction, faulty
connection and thermal protection.
