Signal input

• Line-level inputs: If your source unit offers front and rear
preamp outputs, connect them to the front and rear line-level
inputs on the wire harness using RCA patch cables.
Note: when using low-level signals and remote turn-on lead, set
the "Turn-on Mode" switch to "REM" and the "Input Level" switch to
"LOW".

• High-level inputs: If your audio system's source unit does
not have line-level outputs, connect the speaker output wires
of your source unit to the high-level input wires of the amplifier
harness.

NOTE: When using high-level signals, set the "Turn-on Mode" switch

on when it senses signal from your source unit), and the "Input Level"
switch to "HI".

Speaker Output Connections
Connect your speakers to the wires of the speaker output wiring
harness, observing proper polarity: connect each positive (+) lead
to the appropriate positive (+) speaker terminal, and negative (-)
lead to the appropriate negative (-) speaker terminal. Then plug the
speaker output wiring harness into the DSP Amplifier.
IMPORTANT: None of the speaker output channels can be bridged.

Connecting a second amplifier (sold separately)
To incorporate more power into your system, you can send
a second amplifier a full-range audio signal using the preamp
outputs of the INFDSP4425. Use an RCA patch cable to connect
the preamp outputs to the preamp inputs of the second amplifier.
