hi to those in this discussion
While contemplating the best way to do a test, could some one such as
Klas do the following in the mean time. A recording with the following:-
1- A Mic using PIP
2- the same mic but powered by a battery box with the PIP turned off.
By listening to these side by side , one may able the judge if there is
an audio difference. True, it isn't a definitive test, it may give a
feel if and how PIP is going to impact on our recordings.
Dan. Would the Sony DCM D50 (126 dBu) also could be a good match for the
EM 23.
Concerning noisier mics with 22dB that use PIP. Correct me if I'm
wrong,could there be a noise issue when using some of the noisier
recorders such as Zoom, especially if there is a noticeable increase in LF?
