Description
JL Audio HD1200/1
Free High-Quality Power kit with any HD series Amplifier!
Monoblock Class D Wide-Range Amplifier, 1200 W x 1 RMS @ 1.5 - 4 Ω
Our most power amplifier ever employs our advanced Single-Cycle Control switching design and R.I.P.S. technology to deliver 1200 W of clean power into any impedance between 1.5 and 4 Ω, giving you the highest degree of flexibility in designing your subwoofer system. Tight power supply regulation keeps distortion down and maximizes your bass 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.
While targeted primarily to subwoofer applications, the HD1200/1 is a wide-range amplifier and can also be used to drive high-performance mid-range speaker systems.
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.

Single Cycle Control™ (U.S. Patent #6,084,450*)
Summary:
High-Fidelity, full-range Class D is a reality.
Detailed Information:
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.
