  • 1Description

The Williams Sound IR SY4 is a SoundPlus medium-area wireless infrared system designed to deliver reliable audio monitoring for up to five people in conferences, classrooms, assisted living facilities, and more. It includes the IR T2 infrared transmitter and its power supply, five WIR RX18 two-channel stethoset IR receivers, one charger with five slots, a wall/ceiling mount, and an ADA wall plaque. With a coverage area of up to 18,000 square feet and selectable transmission frequencies, it provides a blend of easy setup and robust power.

Audio inputs to the transmitter include two Euroblock line inputs and a 3.5mm microphone input. An additional Euroblock is provided for control system integration.
