Features

Power Strip: This Profile California AP400 amplifier features a bright red power light strip on the top center of the unit to indicate when the amp is turned on. The 2-3/8" power light strip consists of three LEDs. The green LED on the power/speaker terminal side of the amplifier will also light when power is sent to the amp.

High-to-Low Level Converter: The amp is equipped with an external high (speaker) level to low (line) level converter to allow you to connect the amplifier to a receiver or factory radio without RCA preamp outputs. After splicing the receiver's speaker wires to the converter's speaker wires, you can simply plug the converter into the amp's RCA preamp input.

Line Outputs: The AP400 includes a pair of RCA line outputs for sending an unfiltered signal to another amplifier or component without splitting the signal.

Protection Circuits: This amp has three types of protection circuits: DC offset, short circuit and thermal protection. The red LED on the left side of the amplifier will light to indicate that the amplifier has gone into protection.

Built-In Crossover: This amplifier includes built-in variable high pass and low pass filters, each with a slope of 12dB/octave. The low pass filter is continuously variable from 50-250Hz, while the high-pass filter is continuously variable from 80Hz-1.2kHz. You can configure the amp for low-pass, full range, or high-pass operation with the 3-way switch.

Inputs and Outputs Notes

Gold-plated Terminals: The AP400 features gold-plated speaker and power terminals and RCA jacks for maximum signal transfer and corrosion resistance.

Set Screw Terminals: The power, ground, remote turn-on, and speaker output connections feature set-screw terminals that can accept up to 6-gauge bare wire. A 2.5mm Allen wrench is supplied to tighten/loosen the set screws.

Remote Turn-on: In addition to turning on and turning off the amplifier via the head unit's remote output, the remote turn-on also operates the reset circuit for the amplifier's protection system. The remote turn-on lead must be connected to the head unit in order to reset the protection circuits.

Warranty Note

Warranty: The manual indicates a 1-year parts and labor warranty, however Profile has extended the warranty to three years parts and labor for units purchased from Crutchfield.
