I'm trying to think of the practical implications even before we do testing=
,..
As Raimund says:
1) Switch off the PIP if your recorder has this option and you can
power your mics with an internal such as the ME-10's, but note,..
2) For the majority of PIP mics whose self-noise is 22dB(A)or
greater, any generated PIP noise is not likely to be audible. Any
noise generated by the PIP circuits is not likely to be an issue with
these noisier mics.
3) Those folks who are looking at recorders to use with Klas's EM-23
mics (~14dB[A] self-noise) should invest in a recorder that has input
noise of -122 dBu or less. The LS-10 is the only recorder at this
point that might be on the borderline and it does have switch-able
PIP so using a battery box is an option.
For practical purposes though, the EM23's are the only mics I can
think of that one can use to test whether the PIP in the LS-10
generates noise. Luckily, Klas has both. :-) Rob D.
