ADA COURTROOM ASSISTIVE LISTENING SYSTEM

Description:

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 RX22-4 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 RX22-4 receiver can be used with a neckloop (included) to amplify the participant’s telecoil equipped hearing aid. SoundPlus infrared technology ensures privacy and securi- ty: the message of the proceeding will not travel outside the walls of the courtroom.

Each WIR SYS 4 package includes: two (2) TX9 emitters, two (2) MOD 232 modulators, four (4) RX22-4 receivers, four (4) HED 021 headphones, one (1) NKL 001 neckloop, and one (1) RPK 005 rack panel kit. The WIR SYS 4 meets and exceeds government ADA regulations for public hearing assistance, and is backed by a five-year warranty.*
