PEAVEY CS 4000  4,000 Watt Stereo Power Amplifier   Designed for years of reliable operation, CS Series amplifiers offer the sonic superiority and unsurpassed reliability for which Peavey is famous in a rugged, compact unit. Advanced technologies and extensive protection circuitry allow operation with greater efficiency, even under difficult loads and power conditions. The DDT™ (Distortion Detection Technique) circuit ensures trouble-free operation into loads as low as 2 ohms (4 ohms for model CS 4080 HZ), protects speakers and ensures, protects drivers and ensures sonic integrity even in extreme overload conditions. Peavey’s high-efficiency design uses tunnel-cooled heat sinks and dual-speed DC fans for consistent lower overall operating temperature, resulting in longer output transistor life. Building on the reputation of the world-famous Peavey CS 800, which conquered the power amp market in the 1970s, the CS Series is the global standard bearer for workhorse reliability. Over the years, these amps have benefited from some of Peavey's most popular audio innovations, including our exclusive DDT compression/anti-clipping protection. With its 2RU design and power points up to 4080 watts, this latest evolution of the CS Series is leaner, louder and lighter than ever.
