The Williams AV FM+ PRO Intercom System delivers simultaneous FM and Wi-Fi audio from a single transmitter.
At the center of the system is the FM+ C D (T55C D) transmitter, which replaces the legacy T45 model and adds Dante audio-over-IP, DSP processing, and Ethernet-based control.
Each PPA R37 receiver uses a single seek button for quick channel selection across 17 wideband FM frequencies from 72.1 to 75.9 MHz. This design minimizes user error and makes the intercom system easy to operate in public or shared environments.
Expandable and installation-ready, the system supports assistive listening, one-way audio distribution, and mobile streaming while meeting 2010 ADA hearing assistance guidelines.
