Infrared + Wifi – Best Of Both Worlds In One Box
IR+ Control Center
The IR+ Control Center provides audio over Wi-Fi and Infrared. Infrared is best used for assistive audio in large spaces, or for secured audio transmission within a room. Connect the IR M1 to a Wi-Fi multicast router or in-house network you can stream audio over Wi-Fi to the Williams AV WaveCAST app (available in the iOS app store or Google Play store).
The IR+ Control Center features a distributed infrared emitter array architecture allowing up to four emitters either stacked together for large room arrays or distributed throughout the room to accommodate wings in room design, balconies or other obscured venue locations.
The rack mounted or remotely located IR M1 Control Center comes standard with support for up to four IR emitters. Each emitter runs back to the modulator via a CAT5e cable, providing the audio and power needed to support the remote emitter. Each emitter has a coverage area of 18,000 sq. ft.
*Note: Firmware updates are currently unable to be completed on Mac computers.
