The Language Interpretation System, model WIR SYS 4, is the ideal package for courtrooms that may be required to translate up to four languages simultaneously. Participants wear the R•12-4N body-pack style receiver to listen to the language of their choice. They can sit anywhere in a 11,000 ft2 area and can adjust the volume to meet their comfort level. For the hard of hearing participant, the R•12-4N receiver can be used with a neckloop (included) to amplify the participant's telecoil equipped hearing aid. SoundPlus™ infrared technology ensures privacy and security: the message of the proceeding will not travel outside the walls of the courtroom.
