JL Audio RD900/5

5-Channel Class D Amplifer 70 x 4 @ 4 Ω + 500 x 1 @ 2 Ω - 14.4V

Sleek and powerful, RD amplifiers deliver outstanding amplifier performance and versatility at an unprecedented value.
Developed in-house by the same engineering team that brought you the XDv2 and HD amplifiers, our latest RD amplifiers utilize JL Audio’s exclusive NexD™ switching technologies to generate loads of power with exceptional efficiency to reduce current draw and heat. Each model features a modern, industrial design with a high performance look and finish. For ease of installation and making adjustments, all connections are placed along one side of the amplifier with the controls on top, concealed beneath a removable protective cover.
Just like the XDv2 amplifiers, RD amps are equipped with studio-grade signal processing and automatic turn-on capabilities (via signal sensing and DC-offset sensing) for maximum flexibility. Differential-balanced inputs are also on-hand to combat noise and maximize compatibility with a wide range of signal types. Two brand new features have been added to simplify installation and set-up: easy-to-use LED clipping indicators streamline the input level setting process and stereo output channels include input type switches, eliminating the need for Y-adaptors when bridging.

5-Channel Class D System Amplifier, 70 x 4 @ 4 Ω + 500 x 1 @ 2 Ω - 14.4V

Crafted as an all-in-one, total system solution, the RD900/5 is engineered to power a complete audio system consisting of a subwoofer + four satellite system with 900 watts of high-performance sound. Equipped with our exclusive NexD™ switching technology, this complete power package efficiently generates a potent 70 watts of crystal-clear audio into 4 ohms, plus a robust 500 watts for a subwoofer system, all from a single compact chassis. Each pair of main channels is also fully bridgeable, stoutly producing 200 watts of full-range audio bliss (into 4 ohms), creating an ultra-powerful 3-channel amplifier.
Conveniently located on top of the RD900/5, you’ll find a complement of studio-grade signal processing features, all hidden beneath a removable protective cover. Each pair of main channels is equipped with a 12 dB / octave high-pass filter, with a dedicated low-pass filter for its subwoofer channel. All three crossovers offer continuously variable frequency selection from 50-500 Hz, for precise filtering. Dual-range, differential-balanced inputs are also onboard, capable of accepting most input voltage levels, plus automatic turn-on capability (via signal sensing or DC-offset sensing) for maximum versatility.
LED clipping indicators are also standard equipment for each channel section. This all-new, innovative feature lets you easily set your amplifier’s input sensitivity settings, quickly and accurately, with no special equipment needed. The RD900/5 features a durable, black powder-coated finish and a top-mounted, dual-color LED light strip that reports the overall status and condition. With the addition of an RBC-1 remote level control (sold separately), you can conveniently control the subwoofer’s output remotely from the driver’s seat.
