Need to lift audio from multiple SDI feeds

Hopefully you all might be able to point me in the right direction. Currently we have a BlackMagic ATEM 2 M/E Production 4k switcher unit which receives input signals via SDI from a few Decimator converter boxes connected to the HDMI output of some laptops. We have a few BlackMagic SDI to Analog audio mini converter boxes that lift channels 1/2 from the incoming SDI signal, do a full pass through with the SDI to the switcher and then we route the stereo analog audio to our live audio mixer.This all works flawlessly but I'm stuck buying more of the SDI to analog audio converters any time I want to lift the audio from an SDI source. Not only is this messy in the rack unit, the expense becomes quite high per source.That being said: I'm looking for a rack mount unit that will do exactly what the BlackMagic SDI to Analog Audio mini converters do but for multiple devices. Ideally I'd like to find a product that can handle up to 8 SDI devices. Input, pass through SDI to our switcher and a stereo analog output to our board for each discreet input.I haven't managed to find a product like this out there. Is this not a typical use case? I can't imagine that lifting audio from an SDI feed and sending that to a live mixing console for EQ/Compression/Gating etc. isn't a common thing.Thanks! via /r/videoproduction https://www.reddit.com/r/videoproduction/comments/4xv7r6/need_to_lift_audio_from_multiple_sdi_feeds/?utm_source=ifttt
