What Williams AV does

Williams AV, LLC is a privately held US assistive communication technology company headquartered in Eden Prairie, Minnesota, founded in 1976 by Jerry Williams. The company designs, engineers, and manufactures professional audio transmission systems spanning six core technologies: FM radio frequency, infrared light, Wi-Fi, digital spread-spectrum (Digi-Wave), induction hearing loops, and Auracast Bluetooth Low Energy broadcast audio (via the Infinium platform). Its products serve two end markets — professional venues (classrooms, courtrooms, houses of worship, government facilities, theaters, and interpretation/intercom/guided-tour applications) and individual consumers (the Pocketalker personal listening amplifier line sold direct via e-commerce).

The company monetizes primarily through hardware sales, with quote-based pricing on professional systems and unit pricing on consumer products and accessories. Go-to-market is a hybrid model: global distributors and AV integrators across 60+ countries handle enterprise installations, supported by a US-based direct enterprise field sales team, while Pocketalker personal amplifiers are sold direct-to-consumer online. Revenue streams include professional AV systems, personal hearing products, and a deep accessories catalog (headphones, neckloops, microphones, chargers, wire, etc.). Sub-brands include Pocketalker, SoundPlus, Infinium, Digi-Wave, and WaveCAST.

Williams AV's July 2024 acquisition of TeachLogic expanded its K-12 classroom audio portfolio and added the Ovation DECT amplifier line. Recent strategic activity centers on the Infinium Auracast platform (shipping since August 2025 and awarded 2025 SVC Emerging Technology of the Year), new international distributor signings in Europe and emerging markets tied to the European Accessibility Act, and product expansions planned for InfoComm 2026. The company employs 101-250 people, operates without disclosed private equity or institutional ownership, and has no public revenue disclosures.

Direct peers

• Listen Technologies: Closest direct competitor in assistive listening, interpretation, and guided tour systems; offers ListenIR, ListenRF, ListenWIFI, and Wi-Fi audio streaming across education, government, worship, and venues — effectively Williams AV's mirror portfolio.
• Ampetronic: UK-based specialist in hearing loop/induction systems and a leading alternative to Williams AV's Digi-Loop family; competes most directly in hearing loop amplifiers and counter/perimeter loop categories across transport, worship, and government venues.
• Contacta Systems: Hearing loop and assistive listening specialist with a comparable UK/US footprint; competes with Williams AV on loop amplifiers, IR systems, and counter-loop installations across government and healthcare channels.
• Comfort Audio: Swedish assistive listening and hearing assistance company with secure digital wireless systems for schools and government; competes with Williams AV's Digi-Wave digital interpretation and hearing assistance portfolio in Europe and internationally.
