Crown CT4150 ComTech 4-Channel 4 x 150W at 4/8Ω Power Amplifier

Crown CT4150 ComTech DriveCore™ Series 4-Channel Power Amplifier

The CT4150 is a high-performance, 4-channel power amplifier designed for demanding commercial and installed sound applications. As part of the Crown ComTech DriveCore™ Series, the CT4150 delivers 150 watts per channel into both 4Ω and 8Ω loads, providing powerful and consistent audio performance for boardrooms, conference centers, classrooms, retail spaces, and more.

Built around Crown’s proprietary DriveCore™ technology, the CT4150 integrates the amplifier’s driver stage into a single chip to drastically reduce power consumption and heat output while maintaining exceptional audio fidelity. This efficiency enables the amplifier to deliver consistent, high-quality sound from a compact, convection-cooled 1RU chassis—ideal for installations where space and silence are critical.

The CT4150 includes Phoenix-style connectors for audio inputs and outputs, as well as a universal power supply for easy deployment across global installation sites. Its convection cooling eliminates the need for fans, ensuring ultra-quiet operation in noise-sensitive environments.

Measuring 1.75 inches (4.4 cm) in height, 19 inches (48.3 cm) in width, and 15.9 inches (38.6 cm) in depth, and weighing 10 lbs (4.54 kg), the CT4150 offers a compact, lightweight solution without compromising performance or reliability.

With its robust output, efficiency, and trusted Crown engineering, the CT4150 is an ideal amplifier for integrators seeking reliable, scalable sound in professional AV systems.
