Peavey CPX1 230EB

The Crest Audio CPX1 Power Amplifier 230EB is a robust and cost-effective professional amplifier designed for touring sound systems, fixed installations, and mobile PA applications. As part of Crest Audio’s CPX series, it delivers reliable performance, flexible connectivity, and solid output power—making it an excellent backbone for DJs, live events, and venue installations.

Built with a proven Class-AB amplification topology, the CPX1 provides clean, dynamic sound with strong low-frequency control and stable performance under demanding loads. It supports low impedance operation down to 2 ohms, allowing it to drive multiple speakers efficiently in both stereo and bridged configurations.

Engineered for versatility, the amplifier includes built-in crossover and filtering options, enabling direct integration with subwoofers and full-range systems without requiring external processing. Crest’s GCL™ (Gain Comparator Limiting) system continuously monitors signal conditions to protect both the amplifier and connected speakers from distortion and overload.

With a rugged 2U rack-mountable chassis and dual-voltage operation (including 230V), the CPX1-230EB is ideal for professional users who require dependable amplification in both portable and installed environments.

Performance Highlights:
• Class-AB amplifier design for clean, dynamic audio performance
• Up to 480W per channel @ 4Ω and 960W bridged @ 8Ω
• Stable operation down to 2Ω for flexible speaker configurations
• Built-in crossover (150 Hz) and low-cut filter (40 Hz) for system optimization
