W-IR A4 Emitter Array

The W-IR A4 Emitter Array functions as part of the IR+ Dual Technology audio system.

The IR+ Dual Technology system 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 WIR E4 emitters can be connected to an W-IR M1 modulator with the use of a W-IR A4 Emitter Array. Each W-IR A4 array can have up to 4 W-IR E4’s connected.


The W-IR A4 is not a stand alone system and requires an W-IR M1 modulator and W-IR E4 IR Plus Emitter to function.
