![]() In more technical terms, our approach is a non-linear control method that monitors the switched variable on a cycle-by-cycle basis so that, in each cycle, the average value of the output (power to the speaker) accurately tracks the input signal. By tracking the audio signal, comparing it to the real PWM waveform and then correcting it in each and every cycle (over 400,000 times per second), a multitude of distortion-causing mechanisms can be tightly controlled to enable pristine amplification. Single Cycle Control is a unique approach to controlling a full-range Class D amplifier. High-Fidelity, full-range Class D is a reality. ![]() A black powder-coated, gasketed cover is also provided to protect the controls. This amplifier features a brushed aluminum finish with black powder-coated cast alloy heat sinks and bottom panel. From a pure sound quality perspective, we invite you to compare the real-world, in-car performance of this amplifier to any other amplifier on the market, of any type, at any price. Thanks to R.I.P.S., high power can be delivered over a wide range of load impedances, while the tight power supply regulation keeps distortion down, maximizing sound quality. technology, the HD900/5 delivers 100 W x 4 to its four main channels, plus a very meaty 500 W to its subwoofer channel. Using our Single Cycle Control switching design and R.I.P.S. While extremely compact, this amazing amplifier will comfortably drive a complete high-performance car audio system: that is, four satellite speaker systems and a subwoofer system. ![]() Thanks to its ability to act as a "one-box solution", the HD900/5 is ideal for installations where space is at a premium and sound quality is the paramount goal.

LED clipping indicators are also standard equipment for each channel section. 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. All three crossovers offer continuously variable frequency selection from 50-500 Hz, for precise filtering. 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. 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.Ĭonveniently 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. 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. JL Audio RD900/5 - RD 900 Watts 5 Channel Class D Full System AmplifierĬrafted 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.
