Williams Sound WIR SYS 1SoundPlus Basic Courtroom Assistive Listening System


The WIR SYS 1—part of the SoundPlus® lineup from William Sound—is the the pro’s choice basic courtroom system, offering a complete hearing assistance, language interpretation or private listening solution, designed for a large area (up to 30,000ft² in single-channel mode with the included WIR RX22-4 receivers). Listeners wear the RX12-4N receivers to hear the proceeding anywhere within the listening area. For the severely hard of hearing, the RX12-4N can be equipped with a neckloop (included) to amplify their telecoil-equipped hearing aid. SoundPlus infrared technology ensures privacy and security: the message of the proceeding doesn’t travel outside the walls of the courtroom.
