8. 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.

Ground isolation Jumpers:
Occasionally alternator noise may ap-
pear in a system because the source unit and amplifier may use differ-
ent grounding. To help in this situation, we have provided alternative
grounding connections. Make sure your system is turned OFF before
you move these jumpers.
10. 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 Maximizer circuit
can either increase or decrease the signal voltage of the Bass Resto-
ration Circuit. Depending upon your system, you may 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 suite you
fine. We recommend you try the factory setting first.
