WIR SYS 7522
Mid-Range Infrared System
This system features the NEW WIR TX75 infrared transmitter, ensuring participants in a conference room, courtroom, classroom or other mid-sized venue receive direct, clear
communication of your message without sacricing security.
Includes WIR RX22-4 receivers–ideal for single-or two-channel
Two additional slaves (sold separately) can be added for additional coverage of up to 5,000 square feet each (for total
coverage of up to 15,000 square feet). Placing additional slaves
in the same room increases coverage and enhances freedom of
movement. A single CAT-5 cable carries both power and signal to slaves–truly a one-cable connection. Mounting bracket and power supply are included.
System Includes:
(1) WIR TX75 infrared transmitter
(3) WIR RX22-4 four-channel selectable,
infrared receivers
(3) HED 021 folding headphones
(2) NKL 001 neckloops
(6) BAT 001 AA alkaline batteries
(1) IDP 008 ADA wall plaque
(1) BKT 024 wall / ceiling mounting bracket
(1) TFP 046 international power supply with WLC 004 U.S. mains
