About Williams Sound IR SY21 D

Commercial-grade, large-area WaveCAST enabled Dante infrared system with IR+ transmitter, 2 emitters and array.

- IR+ Control Center with Dante -
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.

This version of the product features Dante.


- IR+ Emitter -
The IR E4 Emitter transmits the audio input from the IR+ (IR M1). Covering a span of 18,000 sq. ft (1,670 sq. meters), a single emitter can be combined with additional IR E4 emitters to provide extra coverage. Up to four emitters can be stacked together for large room arrays or distributed throughout the room to accommodate wings in room design, balconies or other obscured venue locations.

For the IR E4 Emitter to function, it must be connected to the IR M1 modulator. Up to 4 emitters can be connected to the IR M1 directly, and up to 16 emitters can be connected with the use of IR A4 arrays.


- IR A4 Array
The IR+ features a distributed IR 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.

Up to 16 IR E4 emitters can be connected to an IR M1 modulator with the use of the IR A4 arrays. Each IR A4 array can have up to 4 IR E4's connected.

Note: The IR A4 is not a stand alone system and requires an IR M1 modulator and IR E4 emitter(s) to function.


- Four-Channel Infrared Receiver -
Featuring a sleek body-pack design, this four-channel selectable infrared receiver offers a convenient channel selector and user-friendly on/off volume control. It covers areas of up to 30,000 square feet (2,800 square meters) in single-channel mode and is compatible with Williams AV infrared transmitters operating within the 2.3/2.8/3.3/3.8 MHz bandwidth.
