Description:
The 4262A 3G-HD-SD dual stereo analog audio de-embedder extracts two balanced stereo analog audio pairs from any group in the ancillary data space of an SDI signal and provides broadcast quality analog audio outputs. Audio conversion employs high quality 24-bit DACs. Adjustable full scale output levels meet all international standards. Units can be cascaded to enable de-embedding from all four available groups (16 audio channels).
The unit automatically detects whether the SDI input is 3G, HD or 270Mb/s SD SDI. There is automatic input cable equalization and two re-clocked SDI outputs are provided.
The unit requires an external power supply or a rack mounting frame. A 1RU frame is available which takes up to 5 units and a 2U one that takes up to 14. Audio XLR breakout cables and external power supplies are also available.
