Running 40 outputs of Protools HD into an SSL 4000G. Generally print mixes off the SSL stereo buss back to a stereo track in Protools. What would be the single thing I could do to improve this setup? - A high quality A/D converter for the stereo channel I print mixes to. - Big Ben or some other clock. (there is debate about whether Protools works best with its own clock) - ????
