9.  Ground input: For most systems you can leave this jumper in the balanced position, 

for some systems, the power source can find a ground through the RCA connectors. 
In this case, change the jumpers to the UNBALANCED position.

10. Isolation of jumpers: Occasionally the alternator noise may appear on a system be-

cause of the power supply and amplifier different use.  Switch the jumper.  

 

NOTE:  Make sure your system is off before you move these jumpers.

11.  Controls Jumpers: Not all systems are designed equal. Some are designed strictly 

for SPL (sound pressure level), low-maximizer circuit may increase or decrease the 
voltage signal restoration circuit features. Depending on your system, you can choose 
to change these jumpers to a setting higher or lower to maximize the output of and 
protect your speakers.
