4K SDI to audio converter 8ch AES - Blackmagic Design BLM-CONVMCSAUD4K

Mini Converter SDI to Audio 4K is a converter that allows you to extract audio from SDI video signals. Specifically, it extracts 4 channels of analog audio or 8 channels of AES/EBU digital audio from any SDI video connection, providing direct access to the audio signal for output to a wide range of equipment such as mixers, analog broadcast decks, audio monitors, and production systems. Thanks to multi-rate compatibility, it automatically recognizes SD, HD, and 6G-SDI formats, supporting resolutions up to 4K DCI 25p and professional video standards. The device offers balanced outputs on 1/4" jack connectors for both analog and digital audio, and includes advanced features such as SDI signal reclocking, redundant inputs for operational continuity, and a loop-through SDI output. It is USB-controlled with dedicated software for Mac and Windows, and features a universal 12 V power supply with international adapters.
