Peavey CPX4 230EB

The Crest Audio CPX4 Power Amplifier 230EB is the most powerful model in the CPX series, engineered for high-demand touring, large-scale PA systems, and professional installations requiring maximum output and reliability. Designed as a heavy-duty amplification solution, it delivers exceptional headroom, strong low-frequency control, and consistent performance even under extreme operating conditions.

Built with a high-efficiency Class-H amplification topology, the CPX4 provides powerful, dynamic sound while optimizing energy usage and thermal performance. It is capable of driving low impedance loads down to 2 ohms, allowing flexible speaker configurations for large systems and subwoofer arrays.

The amplifier features integrated crossover and filtering functions, enabling seamless system integration without external processors. Crest Audio’s GCL™ (Gain Comparator Limiting) system continuously monitors input and output levels to prevent clipping and protect both the amplifier and connected loudspeakers from damage.

With a rugged 2U rack-mountable chassis, professional-grade connectivity, and reliable cooling system, the CPX4-230EB is built for demanding environments such as concerts, clubs, rental systems, and large venues.

Performance Highlights:
• Class-H amplifier design for high efficiency and powerful output
• Up to 1,600W per channel @ 4Ω and 3,200W bridged @ 8Ω
• Stable operation down to 2Ω for flexible system configurations
• Built-in crossover (100 Hz) and 40 Hz low-cut filter for system optimization
• GCL™ protection system prevents clipping and speaker damage
