Signal Input

Tp to prevent noise and RF inductance, use only high quality shielded audio cables that are no longer than necessary. 

Try to avoid running these low-level cables near cellular phone equipment, electronic management systems or other 

potential interference sources. 

Setting the controls

Turn the gain level on your amplifier to minimum and set the LPF to aproximately 10 o’clock  position. Turn the volume 

on the source unit down before you turn on the power (this will save your speakers if something isn’t right!).  Turn the 

system on, check if the power LED on your amplifier  is ON and the protection LED remains OFF.

Turn the volume of your source unit 3/4 of the way up (this is your maximum volume without distortion).

Slowly turn up the gain on your amplifier to the point when your speakers just start to distort, now turn the gain a little 

down untill the distortion is gone. Turn down the volume on the source unit.

Now it is time to set the x-over to the right setting : Turn the LPF to the position where you like the sound of your bass.

Listen to the system and fine tune the gain on the amplifier if needed.
