Crown Audio XFMR-4 Four-channel Transformer

Crown XFMR-4 four-channel transformer

The Crown XFMR-4 is a rack-mountable impedance-matching transformer engineered to enable conventional power amplifiers to operate within constant-voltage distributed audio systems. It provides reliable conversion between low-impedance amplifier outputs and 70Vrms or 100Vrms loudspeaker lines, making it suitable for commercial installations, paging systems, and large-scale multi-zone audio distribution.

Designed for integration flexibility, the XFMR-4 offers four independent channels of impedance matching, allowing multiple speaker zones to be driven from a single amplifier platform. It ensures stable signal transfer while maintaining consistent audio performance across long cable runs commonly found in installed sound environments. When paired with compatible ComTech DriveCore™ amplifiers, it can directly support 70V and 100V operation, simplifying system design and reducing the need for specialized amplifier hardware.

The unit is built for rack-mounted installation, ensuring clean system organization and professional deployment in equipment racks. It includes jumper cable support for straightforward connection with compatible amplifier systems, reducing installation complexity and improving deployment speed. With its robust electrical design and dependable signal handling, the XFMR-4 is a practical solution for expanding amplifier compatibility in distributed audio networks.
