Rob, Thank you for your detailed response an analysis. With respect to phantom power, the Peavey PV-6 is supposed to be providing 48V phantom power. That's what it says in the manual I got with it, and the mixer itself says "+48V Phantom" on the button for engaging phantom power. My first guess right now is that it's a question of the connection between the camcorder and the mixer. I say that because, as I mentioned in my previous email, I ran two tests-- (1) headphones plugged into mixer -- no noise (2) headphones plugged into camcorder, camcorder plugged into mixer (any output) -- noise, even when no mic is plugged in and gains are all down I don't know if it's a line level or a mic level input, but offhand, I'd suspect it's a mic level input. The camcorder is a Panasonic PV-GS150. For the sake of argument, though, let's say that it is a matter of it being a mic level instead of a line level. I already have a phantom power source in this mixer, so is there something I could do that wouldn't involve buying some new phantom power source? I'd just like the feeling that my investment wasn't wasted. :) If I really need to get a new phantom power supply, I will, but it'll be the last time I do business at that store, because the pro audio guy bilked me. -- Rhett. http://www.weatherlight.com/greentime http://www.weatherlight.com/freetime
