Low Level Input Wiring; High Level Input Wiring - NVX QBUS8V2 User Manual

Low Level Input Wiring

Low-level (RCA) input wiring is preferred for best audio performance. Most trunk
or hatchback installations will require a 15-20 feet RCA cable, while pickup trucks
and under-seat 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

T he high level input(s) should only be used when your receiver lacks RCA outputs.
If the RCA outputs 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!
