Codec audio L&R Balancé AES-EBU RX


This RX codec is a reliable IP to Audio decoder, designed to support HE-AAC and MPEG-1 Layer 3 compressed audio streams and PCM uncompressed stream for audio transmission without quality loss.

As required in equipment of this class, the RX codec comes with several IP audio sources and a built-in MP3/AAC Backup Audio Player. If the audio signal from the main source disappears, the device will switch to the first available backup source, as per the user-defined source priority; when the Main source returns, the unit reverts back to it.

With the optional Stereo and RDS Encoders added, the RX codec becomes a complete tool for audio rebroadcasting. The stereo encoder processor enables a fully digital composite MPX signal with high stereo to be generated. Thanks to the RS-232 port, the RX codec can be transformed from Ethernet to a RS-232 redirector, allowing the control of any other existing equipment over the Internet. The RX codec can be also managed via any kind of Web browser.
