MONOBLOCK  DIGITAL INPUT & OUTPUT CONNECTION

RCA INPUTS 

The RCA inputs ensure the highest quality contacts 

and the lowest noise in your audio system.

RCA OUTPUTS 

Outpur RCA jack to another amplifier.

POWER & PROTECT INDICATORS -  

When the unit is powered on and operating 

correctly the power LED illuminates.

When the unit is malfunctioning or in protect, 

the protect LED will be on.

GAIN ( 6V - 0.2V )

This  adjusts the normal operating level of 

the amplifier by matching the level from 

the headunit.

 

SUBSONIC FILTER ( 10Hz - 50Hz )

Control the high pass frequency for the speaker 

outputs to eliminate extreme low frequencies

LOW PASS FILTER ( 35Hz - 250Hz )

This allows you to tune the response of the amplifier 

at higher bass frequencies to roll off for

a seamless integration into your midbass.

BASS BOOST ( 0 - 9dB )

This allows you to tune amplifier response with up 

to 9dB of boost centered at 45Hz  

REMOTE CONTROL 

Use this to control level of the amplifier from 

your driver’s seat.

GROUND ( GND ) & POWER ( +12V )

The power and ground will accommodate 4 guage

wire. 

Use high quality pure copper wire only.  

REMOTE ( REM )  

REM connector will accept wire sizes from12 to 16 

guage.

This terminal is used to remotely turn-on and turn-off 

the amplifier when +12V DC is applied.  

 

SPEAKER TERMINAL BLOCK 

Connect speaker cables from speaker terminal block 

to subwoofers. 

Subwoofers impedance should be checked carefully. 

S1 minimum impedance is 1ohm.
