The infrared light transmission technology (IR) offers certain advantages whether it is for hearing enhancement and ADA compliance, or, for language translation/audio description applications. The infrared signal does not penetrate through walls thus offering security to sensitive transmissions. This advantage is particularly valuable in courtrooms and multiplex facilities such as movie houses. All receivers can be identical and used in anyone auditorium without interference or signal pickup from adjacent rooms. Two channel systems are available for simultaneous language interpretation, audio description or stereo transmission.
