UHER M136 omnidirectional


Nice lightweight mic.


It must had been made by AKG or just the capsule.


It had been bought from an eBay.de auction at 1eur plus 17Eur shipping. Nobody else wanted it.


It has came with an original frequency response curve data sheet. Very flat but everything above 800Hz is +2dB. 3dB pints at 150Hz and 12KHz.


So it sounds a bit bass heavy for singing.
So a Pleiades filter of about (330Ω,80mH) was found suitable for male singing voice.


Later addition, next day:
For a more full with deeper bass and smooth vocal sound other Pleiades filters can be approximately:
(630Ω,200mH) or (430Ω,400mH).


It's you might have guessed from the higher values of Pleiades filter elements needed it is a 500Ω microphone.


No s problem at all.


Signal path:


male singing voice - M136 at 2 or more inch - (Pleiades (330Ω,80mH) ) - Sony TC-D5 Pro - Sennheiser HD 580 - singer's ears, brain


Sunday's addition:


Vicky was the closed eyes listener this time.
She commented on some lip noise artifacts which were reduced when mic distce was increased to say 6-8 inch.
She preferred a resistance of more than 600Ω for the Pleiades (R,L) filter, ie she wanted more bass.
