1.  Connect the input to the output of the head unit by using high quality patch cords. When your head unit has multiple outputs, 

you can select either INPUT 1 or INPUT 2 based on your previous selection. 

 

2.  If the outputs of your heat unit are FRONT/REAR, you can connect FRONT and REAR to INPUT 1 and INPUT 2 

separately. Then you can select FRONT or REAR by using INPUT SELECTOR SWITCH. 

 

3.  In case of FRONT or REAR L/R, the outputs of this unit are connected to the inputs of the power amplifier which drives 

speaker of high-pass frequency. 
In case of SUBWOOFER L/R, the outputs of this unit are connected to the inputs of the power amplifier which drives low-
pass frequency. 

 

4.  Please reset frequency to match your speaker. 

After considering the output level of your head unit and the input sensitivity of your amplifier, you are recommended to 
adjust the volume of input sensitivity.
