Yeah, the DAK mixer has this. It has a fader as well as level controls for two phono/line inputs. I know those samples I uploaded for you folks aren't exactly the best, as I said they were first attempts and DePopper was used. All the raw data was deleted, so that may make it difficult to pinpoint any noise. The narrator on the first Cure track is probably the best for trying to listen to the background, as it is just him talking.
It was difficult for me to come up with the $219 USD for the DAK system, so I just don't know if I would be able to come up with something better. I regret sending it back now, but at the same time, I wonder if I would be able to piece something together.
