Description

The Williams AV FM 558-12 PRO-02 is a large-area, professional assistive listening system that simultaneously broadcasts dual FM and Wi-Fi audio. This complete turnkey package includes an FM+ T55 transmitter, 12 PPA R38N receivers, a 12-bay charger, and professional mounting and antenna accessories. The Williams AV FM 558-12 PRO-02 is built for mid-size to large venues like houses of worship, lecture halls, and courtrooms requiring ADA compliance. It is unique because it streams traditional 72-76 MHz FM audio alongside an audio-over-Wi-Fi stream via the WaveCAST app, letting users choose between dedicated physical receivers or their own smartphones. The PRO package adds professional installation hardware, including a remote coaxial antenna and a rack panel kit.

Key Features

  • Dual Broadcasting: Streams audio simultaneously over traditional FM (72–76 MHz) and Wi-Fi networks.
  • Comes with 12 PPA R38N multi-channel FM receivers, 12 surround earphones, and 3 neckloops.
  • Professional Gear Included: Ships with an ANT 005 remote coaxial antenna, RPK 005 rack panel kit, and a 12-bay drop-in battery charger (CHG 3512).
  • Advanced DSP Audio: Features adjustable high/low pass filters, compression, and selectable audio presets (hearing assistance, music, voice).
  • OLED Display & Web Control: Built-in high-resolution OLED screen on the transmitter and receivers, plus a hosted web page for easy remote monitoring.
