10. 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.
11. Ground Isolation Jumpers:
Occasionally alternator whine may appear in a
system because the source unit and amplifier may use different grounding. To help
in this situation, we have provided alternative grounding connections. Made sure
your system is turned OFF before you move these jumpers.
12. 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 fine. We
recommend you try the factory setting first.
