CLh series amplifiers feature an ultra-high efficiency amplifier output circuit that reduces weight while increasing output power, reliability and thermal efficiency. 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 low-cut filter.
