The Crown CT475 4-Channel Power Amplifier is a 4-channel power amplifier. This sleek am gives you high quality in a slim design. The amplifier has a 1RU chassis which gives you the option to install in on virtually any equipment rack. It provides 75W per channel into 8 ohms for strong, clear audio with low distortion. DriveCore technology gives you amazing efficiency of over 90% for a great performance to power ratio. It does not require a cooling fan so you'll get truly quiet operation. Powering the Crown CT475 4-Channel Power Amplifier is the pioneering technology of DriveCore. This allows you to easily integrates the amp drive stage into the power output stage fusing everything into a chip the size of a dime. The foundational DriveCore circuitry is comes from major breakthroughs by Crown's own Gerald Stanley with five patents applying to the advanced feedback, modulation and output stage technologies. DriveCore's front-end drive circuits leverage the inherent efficiency of Class D output stages while also maintaining superb sonic characteristics. The results give you an ultra-efficient one-piece audio amplifier circuit that exhibits the exemplary audio quality of a highly evolved Class AB design. Energy efficiency is an integral part of ComTech DriveCore. This series hit the scene with a brand new four-stage universal power supply that adapts to operating demands to assure peak efficiency. Normal, Green, Sleep, and Deep Sleep modes combine to provide everything from full voltage to the supply rails for instant response to limiting power consumption, to less than 1W when not in use. And, because it's over 90% efficient in the DriveCore stage, no fan is required, allowing for ultra-quiet operation
