Low Level Input Wiring; High Level Input Wiring - Harman JBL SW8A-S Owner's Manual

LOW LEVEL INPUT WIRING

Low-level (RCA) input wiring is preferred for best audio performance. Most trunk and underseat
installations will require a 6-12 feet RCA cable. Always use a high quality cable.
NOTE: Do not connect BOTH the high level and low level inputs from your receiver to your
amplifier at the same time!

HIGH LEVEL INPUT WIRING

The high level input(s) should only be used when your receiver lacks RCA outputs. If the RCA out-
puts are not present, connect the speaker outputs from the receiver to the high level input connector
of the amplifier. Be sure to observe polarity to avoid audio phase problems.
NOTE: Do not connect BOTH the high level and low level inputs from your receiver to your
amplifier at the same time!
