How can I broadcast audio from a movie wirelessly?

Episode 1223 (38:53)

Carl from Irwindale, CA

Carl has family outdoor movie parties from time to time. He wants to be able to broadcast the sound of the movie to people who are hard of hearing and have specialized hearing aids, or those who want to use wireless speakers. Leo says that there is one called TeleLoop which uses RF technology. Leo also says he can get a micro power transmitter that can basically create a low power local FM radio station that can broadcast the audio. Scott Wilkinson says that a Bluetooth solution would be a better choice. He'd need a Bluetooth transmitter for that.

The Chatroom suggests Source WholeHouse FM Transmitter and APTX Bluetooth Wireless Transmitters. Leo says that the problem with Bluetooth is that he wouldn't be able to listen from multiple devices and it's got limited range.
