The unit ensures a premium broadcasting experience. Once the audio source is selected, the encoded real-time audio is immediately transmitted over IP-based networks. The enhanced DB91-TX can act simultaneously as an Icecast/Shoutcast compatible Server, Icecast source client or Real Time Protocol (RTP) sender. The audio stream may spread over an IP-based network to one or more DB90-RX, DB91-RX or other compatible IP audio decoders. To address the evolving customer needs, the DEVA Broadcast DB91-TX IP Audio Encoder can also send audio to a number of clients simultaneously. This is possible provided a multicast address is being entered as a client address.
