Modular infrared audio system for large areas with two IR emitters, Wi-Fi audio support, and coverage up to 18,000 sq ft (≈1,672 m²) per emitter.

IR Plus supports up to four IR emitters that can be distributed throughout a venue or linked together for greater coverage. Each emitter connects to the IR M1 via CAT5e cable, providing both audio signal and power. The system also supports audio streaming over Wi-Fi to the Williams AV WaveCAST app.

System Includes

• 1 × IR M1 – IR Plus Infrared Modulator/Control Center and Wi-Fi Audio Server; supports up to 4 IR emitters
• 2 × IR E4 – IR Plus Infrared Emitters; each provides coverage up to 18,000 sq ft (≈1,672 m²) in single-channel mode
• 1 × MLB 003 – Metal Linking Bar for joining the two IR E4 emitters
• 1 × IDP 008 – ADA Accessibility Wall Plaque
