Codec audio L&R Balancé AES-EBU TX
Description
This TX codec is a multi protocol Audio over IP encoder, operating with either analog or digital audio. The signal compression is performed in real time, using the HE-AAC or MPEG-1 Layer 3 encoder and transmitted via TCP/ IP-based network to one or multiple decoders. In order for audio transmission without quality loss to be ensured, it's also supports an uncompressed PCM stream.
It can act simultaneously as an Shoutcast compatible Server, Shoutcast source client, or a Real Time Protocol (RTP) sender. Via the RS-232 port, the TX codec could be transformed from Ethernet to a serial Redirector, allowing control of any other existing equipment over the Internet. The TX codec allows quick integration of the existing audio systems to the Internet. Additionally, the unit can be managed through a standard Web browser and UPnP for easy connection via local area networks. Android and iOS devices are also supported.
