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.
