Description

Williams AV FM+ 558-12 PRO D Dante-Enabled Assistive Listening System

The FM+ 558-12 PRO D System is a high-performance assistive listening solution tailored for mid-size venues, combining advanced audio technology with professional-grade installation accessories.

At the heart of the system is the Dante-enabled FM+ C transmitter, delivering simultaneous FM and Wi-Fi audio with crystal-clear quality and DSP audio processing. It integrates easily with third-party control systems and allows guests to tune in via the WaveCAST app, a WAV Pro receiver (sold separately), or one of the included R38 handheld receivers, each featuring a bright OLED display and support for 17 preset wideband channels (72.1–75.9 MHz).

The system also includes a 12-bay charger with rechargeable batteries, ensuring devices are always ready for use. An ADA wall plaque is included to help venues clearly communicate accessibility options.

For streamlined installation and optimal performance, a coax antenna and rack panel kit round out this complete, future-ready solution.
