This coming week I will be getting a PSR-600 to add to the farm of PRO-95,2051,96,97,163,164 and PSR-500,600 and the new 600 that I am getting this week I have a lot more but older, I use my 97 for my feed now, I picked up three USB sound cards that Lindsay is using for his feed in DC, my question here is can I still use my 97 and the new 600 using stereo feed with the tags option on the 600 and just audio on the 97 the left right thing.
