JL Audio 98223 Class D Five-Channel System Mobile Amplifier
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.
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... with a very serious 900 watts of power!
Using our Single Cycle Control switching design and R.I.P.S. technology, the HD900/5 delivers 100 W x 4 to its four main channels, plus a very meaty 500 W to its subwoofer channel. 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. 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.
This amplifier features a brushed aluminum finish with black powder-coated cast alloy heat sinks and bottom panel. A black powder-coated, gasketed cover is also provided to protect the controls.
Features:
- Single Cycle Control™
Single Cycle Control is a unique approach to controlling a full-range Class D amplifier. 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.
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. This ensures that power supply disturbances, non-ideal switching edge behavior, component non-linearities and other distortion-causing problems are completely cancelled and taken out of the equation.
In addition to the sonic benefits of Single Cycle Control Class D, the technology also results in outstanding efficiency (80% at 1/2 rated power for the whole amplifier, including its power supply), which translates to 60% less current draw than a typical Class A/B car amplifier of equal power. This tremendous efficiency advantage also leads to less generated heat which allows the chassis size to be reduced to about 1/4 the size of a similarly powerful Class A/B design.
So, while there may be less expensive ways to make a full-range switching amplifier, no other Class D control system works faster or more accurately than Single Cycle Control™, which is why no other mobile audio amplifier in the world performs like a JL Audio HD. - R.I.P.S. – Regulated, Intelligent Power Supply
The remarkable R.I.P.S. System ensures consistent power delivery over a wide range of battery voltages and load impedances. - Advanced Rollback Protection
Should a JL Audio amplifier equipped with Advanced Rollback Protection reach an unsafe operating temperature, a special circuit rolls back peak power output, without changing gain, until the amplifier cools down to a safe operating temperature. The condition is generally indicated by a red “Thermal” or “Status” LED state. On VXI amplifiers, the LED ring will flash red. Once the amplifier cools down, the circuit restores full peak power output and the indicator reverts to its normal state. The operation of Advanced Rollback Protection is inaudible in most cases, but it ensures that your music keeps on playing, even under the most demanding conditions. - RealSink™
Most car audio amplifiers rely on big lumps of metal that do a good job of storing heat, but not such a great job of getting rid of it. RealSink™-equipped JL Audio amplifiers feature real cast-alloy heat sinks with vertically-oriented fins. This design is far more effective than the lump-of-metal approach, utilizing the physics of convection and radiation to more effectively exchange heat with the surrounding air. The design of these heat sinks was refined through extensive finite-element analysis, resulting in amplifiers that keep their cool under the most demanding conditions. - HD Mounting Options
The compact dimensions of the HD amplifiers open up a whole range of installation options simply not possible with larger designs. To give you as many mounting options as possible, the design incorporates flexible mounting options for single or multiple amplifier installations. - Differential-Balanced Inputs
JL Audio’s Differential-Balanced Inputs are engineered to combat induced cable noise, which is a common problem in car and marine audio installations. This technology allows for the use of conventional RCA cables, while delivering many of the benefits of a true balanced connection and accepting a wide range of input signal levels.
