After renting a Sennheiser MKH-416, I bought one! I am also getting a MKH-20 and finally I have a Samson wireless system. This gives me 3 XLR inputs. My DSR 250 allows for two inputs at 16-bit/48Khz. So does anyone have any experience with either DV Promix 3 or the Rolls MX422? Or do you have another suggestions? I want to feed three signals into two. I also like the peak limiters on the mixers: some of the best sound I ever recorded was on a GL1 using a Beachtek adapter! Thanks for any input.
