So, the drummer I'm working with has a PA Mixer: A Zebra ZM-0812 powered mixer, 8 channels, and kinda limited on the outputs. (all I could see were 1/4" main L/R out, which are each 150W @ 4ohm)
We were mucking around with it today, he's got his drum mics on 5 of the channels (snare mic, kick, and 3 tom mics which are from a CAD drum mic kit) Overheads are on a small 8ch (4 mic) behringer mixer, since they need phantom power. (he's got a pair of pencil condenser mics)
I couldn't see any other outputs on the PA mixer, just the Mains on the back, and some tape in, aux in on the front, a single send and a single return, and that's it.
So first we tried recording off the mains, and I got nothing but a quiet, thin, buzzy distorted signal going into the line-in on his laptop (which is a mac set to record from the line-in)
So, I switched things around to try coming through his little behringer mixer. PA Mixer Mains -> Behringer since I couldn't see any other outputs. And tried recording off both the control room out and the alts on the behri. Still got a thin buzzy signal from the PA mixer, but the overheads came through okay.
I'm thinking it's gotta be a signal routing issue on his and my part (I'm not used to working with PA mixers) so a manual would be helpful. (Either that, or the PA mixer is shot)
So, I was looking around the net trying to dig up info on this little mixer, and I can't find jack **** about it. Just some obscure vendors selling it, and a few spanish sites mentioning it :P But no manual. And some of the vendor listed specs info is incorrect.
This is the only "correct" info I can find:
the only other vendor listed incorrect info.
At this point I don't know if the PA Mixer is just shot, or if it's user error (routing problem) or something else going on. Tried swapping cables to see if there was a problem there...etc. But no change. The only other thing I can think of, is to get it to his laptop (he has no audio interface) he's sending the stereo out into an 1/8" adapter/splitter. But....the overheads come through just fine...so that can't be it.
I know it's generally bad to record off the mains because you get the mic + the power amp noise. But I don't see any other option. Also, I'm not sure he has the budget to get a better mixer or audio interface. Maybe down the road, but not right now.
Next time I'm over there I'll take some of my stuff with me to try and trouble shoot the signal chain. But yeah, I distrust that PA mixer at this point.
