The sleek and stylish TX75 PRO is designed to maximize coverage area up to 12,000 square feet in single-channel mode when using the RX22-4 receiver. Two slaves (WIR TX75-S) can be added for additional coverage up to 12,000 square feet each (36,000 sq. ft. total), when mounted up to 100 feet from the master transmitter.
