CLh™ 2500

High Efficient Install Power Amplifier


The Crest Audio® CLh™ Series power amplifi ers set a new standard for performance and efficiency for the contracting and installation market. CLh amplifiers feature an ultra-high efficiency amplifier output circuit that reduces weight while, increasing output power, reliability and thermal efficiency.

The Crest Audio CLh 2500 is a ultra-high efficiency, servocontrolled, class D power amplifier that delivers high power through two channels to balanced outputs for the ultimate in common-mode noise cancellation.

The CLh Series includes Crest Audio’s exclusive ACL™ (Active Clip Limiting), which automatically reduces gain at the onset of clipping to prevent amplifier and load damage; over-current protection; DC voltage; channel active and temperature warning. Additional features include a lightweight switch-mode power-supply, remote turn-on, sequential turn-on, and a switchable, built-in lowcut filter.
