1180 is a high-quality multiplexer and de-multiplexer for embedding and de-embedding analog or AES audio onto the SDI signal. It is a very reliable product for the demanding user. It is designed to insert analog or digital audio signals onto a single SMPTE 259M serial component digital video signal. Analog embed and de-embed is a plugin option. Should analog embed be a requirement for future use, a simple plug-in module attaches to the primary PC board. In addition, the 1180 module supports full EDH monitoring and insertion. The multiplex function takes the AES/EBU audio signal and multiplexes the data onto the serial digital signal. The audio signal will be placed onto the SDI video according to SMPTE 272M-1994. In addition of multiplexing, the 1180 is a high quality AES/EBU de-multiplexer (analog embed and de-embed is an option). This unit is designed to extract the digital audio signal from a single SMPTE 259M serial component digital video signal. The 1180 has automatic 525/625 input detection. In addition, this module supports full EDH. A front panel LED indicates when the 1180 detects the selected audio group in the input video stream. Embedded 20 bit audio or extended 24 bit audio are also indicated on the front card edge. A front panel switch is used to tell the 1180 to remove the audio group selected or to pass it through.
