HD

Our flagship amplifiers feature Single-Cycle Control switching technology and R.I.P.S. power supplies to deliver top-flight audio performance.

“Small” is not the only story here.

Making a small amplifier is great, of course... but not if power and sound quality are sacrificed.

This is why 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 allows 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, putting the HD amplifiers in a performance class of their own. 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).
