Description:
The Value Courtroom System, model WIR SYS 2, is the ideal hearing assistance package for courtrooms with limited
budget resources. Participants wear headset style receivers to listen to the courtroom proceeding at the volume of
their comfort level anywhere in a 3,500 ft
2
area. For the severely hard of hearing, 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 security: the message of the proceeding will not travel outside the walls of the courtroom.
Each WIR SYS 2 package includes: one (1) TX9 emitter, one (1) MOD 232 modulator, three (3) headset RX14-2 receivers,
one (1) RX22-4 receiver, one (1) HED 021 Headphone, one (1) NKL 001 neckloop and one (1) RPK 005 rack panel kit.
The WIR SYS 2 meets and exceeds government ADA regulations for public hearing assistance, and is backed by a five-
year warranty.*
