The Anti-Lambo
I have a question about noise and interference.
Background: I'm trying to record my band live. My original plan was to have my keyboard player run line outs to the PA and Audient ASP008 simultaneously. If we plug him into the PA (Mackie 1604 VLZ ---> a pair of E/V ETX 35Ps) there is no problem. But then when I plug him into the Audient at the same time I get a tremendous amount of buzz out of the PA. This happens even if the Audient is turned off. So then I started running a line out the back of the Mackie - a bus out to the Audient. Problem solved. Sort of. Running the keys through the Mackie and then into the Audient is less optimal than running the keys directly into the Audient. There is slightly more hiss. It's not unbearable, I can live with it, but I'd prefer not to. I'm basically running it through two preamps at that point am I not?
So my question is this: What is causing the buzz on the PA when the Keyboard is hooked up to the PA and the Audient at the same time? Is there some sort of thing I can put in the circuit to prevent that?
