Crown® XFMR-4 and XFMR-8 are rack-mountable transformers to provide impedance matching between amplifier outputs and "constant voltage" loudspeakers. This unit allows amplifiers without direct 70V or 100V output capability to drive distributed speaker systems designed to operate at those voltages.
Transformers provide four and eight channels of impedance matching for constant-voltage operation
Provides 70V and 100V output when used only with Com-Tech DriveCore (CT 475, CT 875, CT 4150 and CT 8150)
Allows amplifiers without direct constant-Voltage capability to be easily integrated into distributed systems
Jumper cables are provided to easily incorporate XFMR unit with Com-Tech DriveCore amplifier
