Description
The Crown XFMR-4 is a professional 4-channel rack-mount transformer designed to provide reliable impedance matching between standard amplifier outputs and constant-voltage loudspeaker systems. Ideal for 70V/100V distributed audio installations, it enables amplifiers - particularly the Crown ComTech DriveCore Series - to power commercial speaker lines without built-in constant-voltage capability. With included jumper cables, broad compatibility, and low insertion loss, the XFMR-4 ensures clean signal transfer, consistent performance, and easy integration into multi-zone audio setups.
