Peavey CPX 4 Professional Touring & Install Power Amplifer

Crest Audio CPX Series power amplifier

The Crest Audio CPX Series power amplifier is designed to provide dependable and cost-effective amplification for professional audio environments, including touring systems, installations, project studios, and mobile sound setups. Built with a reputation for sound quality, reliability, and flexibility, the CPX series continues Crest Audio’s tradition of delivering consistent performance across a wide range of applications.

Available in multiple models including CPX 1, CPX 2, CPX 3, and CPX 4, the series offers scalable power output ranging from 480 watts to 1600 watts, making it suitable for different system requirements. The amplifier supports loads from 2 to 8 ohms in stereo mode and 4 ohms in bridged configuration, ensuring compatibility with various speaker setups. Its Class H topology enhances efficiency while maintaining strong output performance and reduced heat dissipation.

A key feature of the CPX Series is the integrated GCL (Gain Comparator Limiting) system, which actively monitors input and output signals to prevent distortion and excessive current conditions. This protection mechanism helps safeguard connected loudspeakers from damage caused by sudden peaks or signal overload while maintaining transparent audio performance.

The amplifier includes built-in crossover functionality with a 100 Hz Linkwitz-Riley filter optimized for subwoofer integration, along with a 40 Hz low-cut filter to remove unwanted low-frequency noise. Flexible connectivity options such as XLR-TRS combo inputs and twist-lock outputs ensure reliable signal transmission. With dual-speed DC fan cooling and rugged construction, the Crest Audio CPX Series power amplifier is engineered for consistent, high-performance operation in demanding professional audio systems.
