The Audio to SDI Mini Converter embeds up to four channels of balanced analogue audio or eight channels of AES/EBU digital audio into 3G, HD or SD-SDI sources up to 1080p60, via four 1/4-inch jacks. A redundant SDI input backs up the dedicated SDI input — useful outdoors or in crowded venues where cable damage is more likely. It covers the same role as the newer Audio to SDI 4K Mini Converter.
