Testing Pleiades K117 1.3V JFET AA battery microphone booster in real recording conditions

 At your risk.


Schematic is:




It was used yesterday to record a rough demo of Tactopoetry, see previous post.


The Shure Unidyne B microphone was at 24in or more, and singing was almost breath whispering. So in order to fully modulate the SONY TC-D5M recorder, this mic booster was used. Very nice edge timbre and very low noise level performance. Piano was gently played at the same time.


It would be nice to have a small box of 2 of these preamplifiers for stereo recording.
