Modular infrared audio system for large areas with Dante, 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 grouped together for greater coverage. The IR M1 D provides a two-channel Dante audio input, while emitters connect via CAT5e cable for audio and power. Audio can also be streamed over Wi-Fi to the Williams AV WaveCAST app.
