PRODUCT DESCRIPTION

The Infinity DSP Amplifier is an audio processor for fine-tuning of
aftermarket audio systems. It is a self-contained audio system with
4-channel powered audio outputs and 2-channel preamp outputs,
an easy-to-use tuning interface a novice can understand, and
detailed tuning capabilities to satisfy even experienced installers.
With a USB connection to access the tuning interface using a
Windows PC, you can control fully variable crossovers, selectable
0-to-48 dB slopes, time delay, 31-band parametric or graphic EQ
adjustment, assignable input-to-output mixer with input channel
summing, channel gain, master volume control, clipping indicator
to ensure the audio output is not distorted, and ability to save up
to 10 presets.

INSTALLATION AND WIRING

IMPORTANT: Disconnect the vehicle's negative (–) battery
terminal before beginning the installation.
• Wear protective eyewear when using tools.
• Choose a safe mounting location. Check clearances on both
sides of the location. Be sure that screws will not puncture
brake or fuel lines or wiring harnesses, and that wire routing will
not interfere with vehicle operation. Use caution when drilling
or cutting.
• When making electrical connections, make sure they are
secure and properly insulated.
• Do not mount the amplifier with the heat sink facing downward,
as this interferes with cooling.

• Using the amplifier as a template, mark the locations of the
holes on the mounting surface.
• Drill pilot holes in the mounting surface.
• Attach the amplifier to the mounting surface with the included
sheet metal screws and washers.
Power and Ground Connections
• Power: Connect the yellow +12V power wire to the positive
terminal of the vehicle's battery. Make sure the 15A fuse and
fuse holder are within 18" (457mm) of the battery.
• Ground: Connect the black GND wire to the negative terminal
of the vehicle's battery, or to the vehicle's chassis near the
battery with a screw. NOTE: If possible, remove any paint from
the chassis for best contact. It is recommended to use a star
washer below the ring connector for a secure connection.
• Remote-In: Connect the red remote turn-on wire to the
"Remote Out" lead of the source unit, if using low-level signal
inputs with an aftermarket stereo. NOTE: If you are using
high-level signal inputs (your vehicle's speaker wires), you can
choose to have the 12-volt DC offset feature turn the amplifier
on when you turn on the vehicle power, or the audio-sensing
feature turn on the amplifier when it detects audio signal. In
either case, you will not have to connect the remote turn-on
wire and can tape or cap it off to prevent the introduction of
noise.
• Remote-Out: Connect the blue remote-out wire to external
devices that require 12V turn-on after the Infinity INFDSP4425.
This connection will allow turn-on of 12V devices after the
amplifier wakes from turn-on by 12V remote-in, DC offset or
audio signal sensing input.
• When all connections are made, plug the harness into the
amplifier.
Power/Protect indicators
The power light will illuminate in green when the amplifier is getting
power and playing. The protect light will illuminate in red if the amp
enters protect mode in the event of conditions such as over/under
voltage, amplifier output circuit failure, or excessive heat.
