X-OVER FREQUENCY CONTROL
A. 

When the crossover control is in the Low-Pass position, this control becomes  

     active allowing you to select your crossover point.

B. 

When the crossover control is in the High-Pass position, this control becomes  

     active allowing you to select your crossover point.

CROSS OVER SWITCH

• 

Full:

 full range frequency.

• 

Low pass: 

the lower frequency under setting point can be pass.

• 

High pass: 

the higher frequency above setting point can be pass.

BASS BOOST  CONTROLS

This amplifier has Bass controls for making good sound combination.

FUSE

The amplifier is equipped with a plug-in auto fuse protecting the set against 
fault conditions. Do not use a fuse with a higher value and never bridge the fuse 
over, as this may lead to irreparability damage so that any claim for warranty is 
denied.

GND (-) = GROUND CONNECTION

Connect the GND terminal to the chassis ground of your car and take care of    
best electric and mechanic contact. ln doing so, drill a hole in to the car chassis  
near the amplifier then remove color, dirt, or any other substance from the  

 

ground point. Thereafter fasten the cable end with added ring terminal by  

 

using a screw. Ensure that the ground connection is as short as possible and    
that the cable diameter is sufficient (min 4mm”). Route the ground cables from  
the radio and all other equipment parts, like  equalizer, active crossover network 
or other amplifiers, to the same ground point.

+ 12V  =  POWER SUPPLY

Connect the BATT terminal to the positive pole of the battery with a lead cable 
and add a fuse into the power cable in a distance of not more than 30 cm from 
the battery. The lead cable's diameter should be at least 4 mm’ for a length of 
3 m and 6mm" for a length of 6m.
