AtlasIED CP400 Dual-Channel, 400-Watt Commercial Power Amplifier

The AtlasIED CP400 is a professional-grade, dual-channel power amplifier engineered for high-performance contractor installations. Designed with esoteric-grade toroidal power supply and output transformers, the CP400 ensures exceptional reliability, true transformer output isolation, and extended frequency response (-3dB @ 30Hz–16kHz via transformer output). This makes it the ideal solution for demanding commercial sound systems, including large-scale distributed audio, constant voltage systems, and high-SPL reinforcement setups.

With 25V, 70.7V, 100V, and direct-coupled outputs (2, 4, 8 Ohm), the CP400 offers installation flexibility while maintaining electrical isolation and safety. Balanced XLR and barrier strip inputs, rear-mounted stepped attenuators, and dual-speed fan cooling ensure dependable, low-distortion performance in mission-critical environments. The CP400 also includes UL60065 certification, meeting global safety standards for professional audio.

Whether you're outfitting a house of worship, auditorium, or multi-zone commercial venue, the AtlasIED CP400 delivers high power, versatility, and long-term durability at a cost-effective price point.
