FM+ C with Dante is the first transmitter of its kind to offer an FM broadcast and Wi-Fi audio broadcast from a single input source. Whether using the FM+ C for assistive listening, language interpretation, or audio description, this dual broadcast technology gives users the option of listening to real-time audio stream on their smartphone or tablet using the free WaveCAST receiver app (iOSandAndroid) or use an available FM receiver from the venue.
The FM+ Chas support for Telnet commands via an Ethernet port enabling AV professionals to control and monitor the FM+ C using third-party room control systems.
