Thanks, John. It’s good to know that the frequency shouldn’t affect the noise. The thing is, I’m getting nice, round, detailed audio from this setup, but there is a hiss floor that I can’t seem to prevent during recording.

The one time recently when I captured clean audio, it only sounded hiss-free when the peaks were between -20 and -30 (as they were in the raw track). When I raised the levels for the web — a recent video series I completed is being delivered only online — the silence turned into a constant hiss.

To possibly complicate matters a bit, I’m finding this problem with my wireless lav system (Audio Technica Pro-88W) and a wired, handheld mic (Shure SM58). While the former is admittedly a bit humble, I’m under the impression that the Shure is actually a very good mic — so I’m particularly confused.

Jordan,

Nearly two years after you posted this very good question, I’m wondering — how have your tests and John’s advice worked out? Have you been able to avoid that hiss during recording? Did you find the solution in setting the output volume and record volume to the same levels?

I’m having similar problems with hiss and wonder whether I have mismatched output and record levels, as John guessed, or if my wireless system simply has too low of a frequency (it’s about 170 Mhz).

Thanks for any guidance you can offer.
