When the HD amplifiers were introduced in 2008, they wowed the industry with their amazing technological content and impressive power density. Subsequent and continued success in the marketplace is testament to the excellence of their design. They remain unmatched in offering compact packaging, along with the flexibility and stability of our Regulated, Intelligent Power Supply (R.I.P.S.) technologies.
“Small” is not the only story here. Making a small amplifier is great, of course... but not if power and sound quality are sacrificed. Our engineering team focused on achieving world-class fidelity first, and then on making our HD amplifiers amazingly powerful, efficient and small. These efforts led to a remarkable switching amplifier technology called Single Cycle Control™, which allowed all of these goals to be achieved.
This exclusive core amplifier technology is mated to our regulated, intelligent power supply (R.I.P.S.), advanced thermal management systems and a full complement of studio-grade processing features. Behind every HD’s removable security cover, you will find studio-grade signal processing with fully variable crossover filters. Also included are our noise-killing, highly flexible differential-balanced inputs with remote level control capabilities via the HD-RLC remote level control (optional).
We invite you to sonically compare the HD amplifiers to any amplifier, at any price. We think you will quickly discover that all the old amplifier compromises are suddenly irrelevant.
Ensures remarkably consistent power delivery over a wide range of battery voltages and load impedances.
Groundbreaking amplifier technology delivers world-class fidelity, power and performance from an impossibly small package.
HD Amplifiers feature JL Audio’s exclusive R.I.P.S. (Regulated, Intelligent Power Supply) technology to maintain rock-solid audio performance with any speaker load from 1.5 - 4 ohms, even with fluctuating battery voltage. This is a feature you won’t find on any other amplifier.
Removable power and speaker plugs permit high-integrity connections in tight mounting locations.
Lateral mounting feet permits installation in very tight space applications.
