Description

Williams AV FM 557 PRO system eliminates the need for public venues like courtrooms, conference spaces, and houses of worship to choose between legacy FM hardware and modern smartphone-based accessibility. Powered by the FM T55 transmitter, it integrates WaveCAST Wi-Fi server technology so users can either use included traditional FM belt-pack receivers or bring their own smart devices to stream audio via the free WaveCAST app. The PRO package includes practical gear upgrades like multi-bay chargers, rechargeable batteries, a rack panel kit, and a remote coaxial antenna for clean professional deployment.

Key Features

  • Simultaneous Dual Broadcast: Transmits audio concurrently over 72–76 MHz FM and local venue Wi-Fi.
  • Bring-Your-Own-Device (BYOD): Supports iOS and Android streaming via the WaveCAST app for discreet smartphone listening.
  • Professional DSP Audio: Built-in digital processor with adjustable high/low-pass filters, selectable compression (1:1, 1.5:1, 2:1), and voice/music acoustic presets.
  • Comes with 4 PPA R37N single-channel FM receivers, EAR 022 surround earphones, NKL 001 neckloops, 2-bay battery chargers, a remote coax antenna (ANT 005), and a rack mount kit (RPK 005).
  • OLED Screen & Web Control: High-resolution 3.12-inch front display panel alongside a hosted web page for easy remote setup and network monitoring.
