Crown XFMR-4 4-Channel Rack Mountable 70V/100V Constant Voltage Transformer

Crown XFMR-4 4-Channel Constant Voltage Transformer

The XFMR-4 is a rack-mountable 4-channel transformer designed to provide impedance matching between standard amplifier outputs and constant voltage loudspeaker systems. It allows amplifiers without direct 70V or 100V output capability to operate efficiently with distributed speaker systems commonly used in commercial audio installations.

Ideal for professional environments such as hotels, houses of worship, schools, and commercial facilities, the XFMR-4 simplifies integration between amplifiers and constant voltage loudspeakers. By converting amplifier outputs for 70V or 100V operation, the unit allows installers to build reliable distributed sound systems using amplifiers that would otherwise not support constant voltage applications.

When paired with Crown ComTech DriveCore series amplifiers, the XFMR-4 can provide both 70Vrms and 100Vrms outputs. Included jumper cables make it easy to integrate the transformer with compatible amplifiers, allowing for fast and straightforward installation in rack-mounted systems.
