The CADAudio PX5002 Astatic is a high-performance, 2-channel Class-D professional power amplifier designed for commercial audio installations, portable sound systems, houses of worship, educational facilities, and corporate AV environments. Delivering up to 2 × 500W at 4 ohms in stereo mode and 1000W in bridge mode at 4 ohms, it provides powerful amplification in a compact, space-saving 1U rackmount design.

Built for flexible system configuration, the PX5002 supports stereo, mono (parallel), and bridge operation to accommodate different loudspeaker setups. Its high-efficiency switch-mode power supply with soft-start circuitry helps deliver reliable performance while maintaining efficient operation. Selectable input sensitivity allows the amplifier to integrate with a variety of professional audio sources.

For dependable operation, the PX5002 features a peak limiter, switchable 75 Hz low-cut filter, and comprehensive protection against DC faults, overheating, overloads, and short circuits. Temperature-controlled variable-speed fans manage heat, while balanced XLR connections, loop-through outputs, and three Speakon speaker outputs provide practical connectivity for professional sound systems.
