Williams AV IR E4 IR 48V DC Emitter, Supplied by IR M1 via CAT5e Cable, Black

Ensure every listener receives crystal-clear assistive audio with the Williams AV IR E4 IR emitter — a professional IR audio transmitter engineered for large, complex venues. As part of Williams AV's Pro Assistive Listening Devices lineup, the IR E4 delivers distributed infrared coverage up to 18,000 sq ft in single-channel mode and is designed to work with the IR M1 modulator for reliable, managed audio distribution.

Installers benefit from flexible deployment: stack emitters for high-output arrays or distribute them throughout the room to serve balconies, wings, and obscured seating. The unit is powered via 48V DC from the IR M1 and connects with standard CAT5e cable, simplifying wiring and integration with existing security, surveillance and monitoring infrastructures. Its discreet black ceiling/wall form factor keeps the system unobtrusive while supporting scalable configurations (4 emitters per IR M1; up to 16 with IR A4 arrays).

Note: the IR E4 is not a standalone system and requires an IR M1 modulator. Ideal for theaters, auditoriums, houses of worship and secure facilities, the IR E4 helps you meet accessibility and monitoring needs—pair it with an IR M1 to design a tailored assistive listening solution.
