FM+ C 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 (iOS and Android) or use an available FM receiver from the venue.
The FM+ C has support for Telnet commands via an Ethernet port enabling AV professionals to control and monitor the FM+ C using third-party room control systems.
This version of the product features Dante.
System Includes:
(1) ANT 025 antenna
(1) TFP 062 power supply
(1) WLC 004 line cord
