hi, just bought a 4000 with the spdif. I was a bit fast on the trigger, and thought it actually had the adat card, but only spdif and 8 analog. I will connect the 4000 to a "mastering rig" with the 2192. so then I will be fine with the spdif, right? I only need 2 channels at 24bit, not the 8 in adat? thanks!
