im having an external interface(no balanced input tho) witch can be powered by 9v, i suppose it cuts off the noisy usb ground and power when using a 9v psu(havent tested, if not ill be using one of those usb isolators) im in a need for clean 9v line with common ground for the audio interface and the instruments, preamps and fx that go in to it(around 3amps) The point is, i am on the crossroads of building a nice separate regulated 9v psu from another transformer or just to regulate(and somehow cancel the noise from) the 12v from the smps. Is there any way to isolate this noisy computer ground just for the regulated 9volts? if id manage to scope the noise would that allow me to filter it easily? any tips with that?
thx for the stuff mosaic, comp and a noise gate is not working for me since its too much that would get clipped off at this point, for now i also cant get a separate line for the studio, but i definitely will in the future
