Features

Meets ADA compliance for jury deliberations rooms.
Complete system with carry case.
Portable, quick, easy set-up.
Up to 12,000 sq ft coverage when used with RX 22-4 Receiver
Up to (2) TX75-S slave emitters available for extended coverage up to 36,000 sq ft. total.
Master unit has troubleshooting lights built in.
Separate Phoenix Contact connector audio inputs for each channel (2.3/2.8MHz) accept balanced or unbalanced line-level inputs, use together for stereo operation or seperately for mono.
Unit senses if ony one channel is in use and doubles the output power on that channel for twice the coverage.
Power-Saving: if no audio is present after a few minutes, unit automatically disables power to IR diodes, reducing power consumption by 80 percent.
Looks great! Sleek, professional styling complements room aesthetics.
