The Crown CT4150 is a professional four-channel power amplifier designed to provide high-quality audio performance, installation flexibility, and long-term reliability for installed sound and broadcast environments. As part of the ComTech DriveCore series, the amplifier combines advanced DriveCore technology with efficient Class-D amplification in a compact 1RU rackmount chassis, making it ideal for space-conscious professional audio installations.
The amplifier delivers 125 watts per channel into 4 or 8-ohm loads, providing clear and powerful sound reproduction with exceptionally low distortion. At the core of the CT4150 is Crown’s innovative DriveCore technology, which integrates the amplifier drive stage and power output stage into a highly efficient architecture. This design achieves efficiency greater than 90% while maintaining audio quality comparable to advanced Class AB amplifier designs.
Designed for quiet operation, the CT4150 utilizes convection cooling and requires no cooling fan. This silent operation makes it particularly suitable for conference rooms, houses of worship, educational facilities, recording environments, and other noise-sensitive installations. Flexible input routing capabilities allow any input signal to be assigned to any of the four output channels, simplifying system configuration and expanding installation possibilities.
The amplifier incorporates integrated Life-Safety features along with patented feedback and protection circuitry to safeguard connected systems and maintain dependable operation. A universal power supply supports worldwide voltage standards, making the amplifier suitable for international deployment. With support for 2 to 16-ohm speaker loads, compact rackmount installation, and efficient DriveCore performance, the Crown CT4150 provides a versatile and reliable solution for professional audio applications.
