And this is my last post on the subject. I don't think I can be any clearer about what the problem is. But I don't think you'll admit to it.
Argh! I already *did* admit there was a problem, right back where I tested the thing and said I could hear the very quiet beep at maximum gain settings, using headphones full up, among a load of other electronic self-noise. That's exactly the problem you are talking about, isn't it?
It is perfectly clear to me that your expectations of the H4 proved to be greater than the reality of it, whereas I expected a lot from it, and as it turned out, got even more, because I use it to record MUSIC, not SPARROWFARTS.
Obviously the fact you are disappointed isn't your fault, so it must those danged Zoom marketing people with their pictures of streams and so on.
So forget about the workarounds and invest your energies in complaining about the spotty wankers with guitars, dreary singer-songwriters, and the like. I'm sure you'll be much happier.
