so the other night i wanted to split my mic signal and run it to 2 different pre's. i have a pair of xlr splitters that i got from leegeddy here. and used both a v3 and an ad20. i had no problem getting a signal on the v3 side, but the ad20 side was giving me nothing. anybody know why? did i need to run the ps2 on the ad20 side too?
