Crown CT475 ComTech 4-Channel 4 x 75W at 4/8Ω Power Amplifier

Crown CT475 ComTech DriveCore™ Series 4-Channel Power Amplifier

The CT475 is a professional-grade, 4-channel power amplifier designed for fixed installations requiring high-performance audio and dependable, space-saving operation. Part of the ComTech DriveCore™ Series, the CT475 delivers 75 watts per channel into both 4Ω and 8Ω loads, making it ideal for commercial environments such as boardrooms, classrooms, retail spaces, and more.

At the heart of the CT475 is Crown's advanced DriveCore™ technology, which integrates the amplifier driver stage into a single IC chip, significantly reducing power consumption, heat output, and physical size without compromising audio quality. This innovation allows the CT475 to offer exceptional efficiency and performance in a compact 1RU chassis.

The CT475 features Phoenix-style connectors for inputs and outputs, and a universal power supply, making it a versatile choice for integrators. Its convection-cooled design ensures silent operation—ideal for quiet environments where fan noise would be disruptive.

Physically, the CT475 measures 1.75 inches (4.4 cm) in height, 19 inches (48.3 cm) in width, and 15.9 inches (38.6 cm) in depth. It weighs 10 lbs (4.54 kg), and its sleek 1U rackmountable design saves valuable rack space.

Whether deployed in corporate AV systems or commercial distributed audio applications, the Crown CT475 delivers clean, reliable sound with the legendary performance and efficiency Crown is known for.
