SoundPlus® T3 Infrared System with Stethoset Receivers

IR SYS33

The SoundPlus® T3 stethoset receiver system features the upgraded T3 medium-area infrared transmitter, now with the added convenience of hands-free, under-the-chin stethoset receivers.

Powered by advanced LED technology, the two-channel T3 transmitter delivers stronger, more efficient audio signals with enhanced coverage, surpassing previous models. Designed to prevent signal spillover, it’s perfect for adjacent rooms, with a coverage area of up 19,000 sq ft (1,765 sq m) with the RX 2 stethoset receiver and up to 32,000 sq ft (2,972 sq m) with the RX22-4 handheld receiver.

This comprehensive system includes five wireless, two-channel stereo stethoset receivers and a five-bay charging station. The lightweight stethoset receivers are comfortable to wear and provide excellent speech intelligibility and crystal-clear audio quality. For easy ADA/disability compliance, the system has everything you need: a power supply, charging bay, ADA wall plaque, and a discreet wall/ceiling mounting bracket to seamlessly integrate with any room’s aesthetics.
