A single phase splitter? I've tried that but not had success with it yet. I'm looking to do a low component count phase inversion switch and want the positive and negative output to have been affected by the same amount of circuitry/noise etc. I don't want to flip one and have it be a slightly noisier version, if that's possible. Ideally I'd like the signal not to be affected at all by the inversion stage but realize that's probably impossible with an active, unbalanced switching.
Dealing with mono.

80hinhiding said:I would do that with balanced input, but I'm also dealing with unbalanced input so I was looking for a solution to handle both.
