Description:
The Basic Courtroom System, model WIR SYS 1, is the complete hearing assistance solution for the courtroom.
Listeners wear wireless RX22-4 receivers to hear the proceeding anywhere in a 28,000 ft

ing aid. SoundPlus infrared technology ensures privacy and security: the message of the proceeding doesn’t travel
outside the walls of the courtroom.
Each WIR SYS 1 package includes: one (1) TX9 emitter, one (1) MOD 232 modulator, four (4) body-pack style RX22-4
receivers, four (4) HED 021 Headphones, one (1) neckloop and one (1) RPK 005 rack panel kit. The WIR SYS 1 meets
and exceeds government ADA regulations for public hearing assistance, and is backed by a five-year warranty.*
