INPUT

Connect RCA ourput cables from the headunit 

to OKUR digital amplifiers’ RCA Input.

OUTPUT

Is used when connecting multiple amplifiers 

POWER & PROTECTION INDICATOR

Power LED - Green-lit shows normal operation 

Protect LED - RED-lit shows general malfunction, 

faulty connection or thermal protection 

GAIN ( 6V ~ 0.2V )

Matching the output voltage of the headunit's 

RCA line-outs to OKUR amplifiers’ input section.

SUBSONIC FILTER ( 10Hz ~ 50Hz @ 24dB/Oct )

Control the high Pass point for the speaker outputs

to eliminate extreme low frequencies that can damage

your subwoofers.

BASS BOOST ( 0~9dB @ 45Hz )

It boosts the bass 0 ~ 9dB

REMOTE LEVEL CONTROL PORT

This port is for connecting remote gain level control.

LOW PASS FILTER ( 35Hz ~ 250Hz @ 24dB/Oct )

Controls the low pass point for the speaker outputs.

PHASE ( 0 ~ 180 degree )

It control phase from 0 ~ 180 degree

OUTPUT MASTER / INPUT SLAVE 

OUTPUT MASTER / INPUT SLAVE connection makes 

OKUR digital amplifiers as daisy chain connection 

to 2 ohm.
