UNIVERSALLY COMPATIBLE - The transmitter dongle of the blafili RTX can transmit audio from any audio device that outputs audio through an RCA, USB-C or optical jack( 44.1kHz ONLY ) – TV, Projector, Stereo Receiver, Blu-ray Player and even some electric musical instruments. The receiver dongles can be used with any audio “receiving” device that supports RCA, for instance speakers.
