How do IR, infrared transmission systems, and RF, radio frequency transmission systems, perform in different environments?
If you want to broadcast in large spaces (especially outside), even on multiple channels, as a rule of thumb radio frequency systems are your best bet. They provide a strong and reliable signal, which is able to pass through walls and opaque objects. It’s the most economical, simple-to-operate choice for churches, auditoriums, stadiums, classrooms and boardrooms. It even works well in the open air. Radio frequency receivers consume more electrical power than the infrared type; therefore battery life is considerably shortened. Finally, with the advent of digital electronics and signaling, infrared has taken the lead with regard to component features — a lead which is being diminished by some of the new models of radio frequency transmission systems. With Infrared systems, transmission is confined within opaque walls, making it a good choice for movie theaters, boardrooms, and courtrooms – anywhere privacy is valued. Infrared systems are also immune to radio interference. Receiver manag
