Founded in 1976, Williams Sound is located in Eden Prairie, Minn., a suburb of Minneapolis / St. Paul. A market leader in supplying hearing assistance and audio description facilities for cinemas, theatres and other public access locations.

Sound Associates is proud to have helped introduce this important technology to cinemas – and the partnership between Williams Sound and Sound Associates has ensured that the vast majority of UK cinemas can now cater for audiences with hearing and visual difficulties – the Williams Sound system delivers “Hearing Assistance” (HI) and “Audio Description” (VI) to cinema audiences.


The powerful WIR TX90 transmitter combines modulator and emitter technology into a single operating unit, which reduces operating costs, eliminates the need for rack space and eases set-up. The WIR TX90 features application pre-set controls for music, voice or hearing assistance applications – no guesswork required for audio configuration. Everything you need for installation is in the box.
