A professional grade audio power amplifier specifically designed for demanding contractor applications, the CP400 features esoteric grade toroidal power supply and output transformers. These transformers were chosen for their outstanding reliability as well as extended frequency response (-3dB @ 30Hz - 16kHz via transformer output).Now you can have the peace of mind that systems specified with the CP400 will have true transformer output isolation, a feature that previously may have not been affordable due to the cost of quality external transformers.CP400's two independent channels ensure maximum channel separation and ultra low distortion figures while providing years of faithful service.Whether your application is a large distributed constant voltage sound system or a high SPL sound reinforcement system, the Atlas Sound CP400 is the perfect answer for high power/low cost amplification needs.
