Product Description

The JL Audio HD900/5 is a very powerful and compact five-channel amplifier utilizing patented Single Cycle Control™ Class D technology for all channels. This groundbreaking technology delivers reference-grade, full- range sonic performance while requiring

far less current from the vehicle’s electrical system than a conventional amplifier.

JL Audio’s exclusive R.I.P.S. power supply design optimizes the output of each channel section for any impedance between 1.5 and 4 ohms per channel (3-8 ohms bridged on front and rear sections) allowing you to get full use of the HD900/5’s performance capabilities with a wide range of speaker systems.

The tightly regulated power supply design also means that the HD900/5’s clean power output capability remains stable over a wide range of vehicle voltages, resulting in enhanced fidelity.

The HD900/5 flexible, studio-grade signal processing allows it to be deployed in several different system configurations:

1)As a five-channel amplifier in a bi-amplified system, driving four satellite speakers (100W x 4), plus a subwoofer system (500W x 1).

2)As a very powerful three-channel amplifier in a bi-amplified system, driving two satellite speakers (150W x 2, bridged), plus a subwoofer system (500W x 1).

3)As a five-channel amplifier in a tri-amplified system, driving two tweeters (100W x 2), plus two woofer/mids (100W x 2), plus a subwoofer system (500W x 1). An external 2-way crossover is required for this application.

The HD900/5’s flexible input and crossover sections permit operation with a wide variety of source units and system configurations.

It can be operated with a single pair of stereo inputs, with two pairs of stereo inputs (front and rear) or with separate inputs for its front, rear and subwoofer channels.

As we said, it’s very flexible.
