9. Input Grounding: For most systems you can leave this jumper set in the
BALANCED position. In some systems, the source unit may look for a ground
through the RCA connectors. In this event, you should go ahead and change the
jumpers to the UNBALANCED position.
10. Ground Isolation Jumpers: Occasionally alternator whine may appear in a
system because the source unit and ampli er may use di erent grounding.
To help in this situation, we have provided alternative grounding connections.
Made sure your system is turned OFF before you move these jumpers.
11. Bass Output Control Jumpers: Not all systems are designed the same, some
systems are designed strictly for SPL (sound pressure level) while others are a
little more tame. The Bass Maximize circuit can either increase or decrease
the signal voltage of the Bass Restoration Circuit. Depending upon your
system, you may opt to change these jumpers to a higher or lower setting to
maximize your bass output and protect your speakers. In most systems the
factory setting will suit you ne. We recommend you try the factory setting
rst.
