FM T55C Assistive Listening System – Hybrid Wi-Fi
$ 1540
Looking to combine the wide coverage of FM with the convenience of a bring-your-own device? The FM T55C assistive listening system transmitter from Williams Sound is your best (and only) choice! This transmitter is the first on the market to combine FM and Wi-Fi so your listeners can tune in either on your facility’s FM receivers OR their smartphones.
The FM T55C Wi-Fi broadcast uses Williams Sound’s WaveCAST system, meaning that listeners simply download a free app at the Android or Apple app stores.
This allows them to receive crystal clear digital audio with the comfort and discretion of using their phone and headphones.
The WaveCAST app allows the user to choose which channel to listen on and adjust the volume as desired. The transmitter uses digital signal processing (DSP) technology to deliver crystal-clear audio to both FM and smartphone listeners.
The FM+ T55C assistive listening system is designed with the flexibility and comfort of listeners in mind. Those who want to use their phones for a discreet listening assist can do so. It’s easy to provide traditional FM receivers to audience members who do not have phones or choose not to use the app for whatever reason.
Simply issue them an FM receiver and earphone combo as usual and they will be able to pick up the FM feed on one of several channels operating on the 72-76 MHz spectrum.
The FM T55C system is fully compatible with all past (and future) Williams Sound FM receivers.
