I played a gig last night with my PF500 and I used the XLR out to go direct into the PA. The problem was that the signal was way too loud for the PA. The sound guy couldn't get the volume down into the mix. I switched the -40dB switch in and that cut the volume but at this point the sound guy lost his patience (he was an hour late) and just threw a mic on the cab. This wasn't my preferred choice in getting to the PA but it was a small enough venue that my cab did most of the heavy lifting anyway. So, to avoid this in the future should I always have the -40dB switch pushed in when going direct or does it depend on how the PA is wired? Does anybody use the built in direct out on the PF500 or are most of you using external DI's?
