The 4261A 3G-HD-SD analog audio embedder inserts two balanced stereo analog audio pairs into any group in the ancillary data space of an SDI signal.

The unit automatically detects whether the SDI input is 3G, HD or 270Mb/s SD SDI. Audio conversion employs high quality 24-bit DACs. Adjustable full scale input levels meet all international standards. There is automatic input cable equalization and two re-clocked SDI outputs are provided. Units can be cascaded to enable embedding into all four available groups.

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.
