Not necessarily. It might be a mono signal that's been duplicated across two outputs. It's only 2-channel if it can record two separate sounds at the same time. You can get microphones which, in a single unit, record more than one channel at once. Their labelling or artwork on them normally makes it clear that they have L and R (or more than that) inputs. What makes and models are your mics? -- Jeremy Nicoll - my opinions are my own.
