it can be done, ive ran this way before, just take the aes out of the v3 to the ad2k wordclock in, i beleive the light on the front will tell you if its locked to an external clock
dont forget that the input of the ad2k is reverse polarity. if you want to matrix with 4 channels using v3 and ad2k, make sure you flip pins 2 and 3 on the short xlrs to the ad2k (unless your v3 doesnt have polarity fix, in which case both signals would be inverted.)
Cool--hope it works for you. With the D8 in the picture, I'd probably make sure the V3>MT and AD2K were at 16 bits. Not sure how well this would work if you mix 24 and 16 bits. Get that second MT and go back to 24 bits.
The HDP2 would certaily be an easier solution (heck, an R-44 would be much easier and cheaper than the Tascam, at least new), but you're probably getting better A/D conversion this way.
