Features

  • Meets ADA compliance for jury deliberations rooms.
  • Complete system with carry case.
  • Portable, quick, easy set-up.
  • TX75-S slave emitter available for extended coverage.
  • Master unit has troubleshooting lights built in.
  • Separate RCA 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.
