AtlasIED CP Series Dual-Channel Commercial Power Amplifier

The AtlasIED CP400 is a professional-grade dual-channel power amplifier engineered for demanding commercial audio installations. Designed with esoteric-grade toroidal power supply and output transformers, this amplifier ensures extended frequency response and outstanding reliability. Ideal for both large distributed constant-voltage systems and high SPL reinforcement systems, the CP400 offers true transformer output isolation—eliminating the need for costly external transformers while maintaining consistent audio performance.

This amplifier delivers 25V, 70.7V, 100V, and direct-coupled (2‑Ohm, 4‑Ohm, 8‑Ohm) outputs via secure barrier strips. Featuring balanced inputs on both barrier strip and XLR connectors with loop-through functionality, dual-speed high-efficiency fan cooling, power-up muting, and rear-mounted stepped attenuators for tamper resistance, the CP400 is built for longevity, flexibility, and safety in any commercial sound application. It is UL Listed and complies with global safety standards.
