It had arrived the day before yesterday.
The UHER M534 is not made of plastic although it may look like it is when viewed online. It is heavy and it feels metal. It looks a bit like a small MD421 but a metal one. It seems to have a relatively small diaphragm which can be a good thing in terms of sound detail.
A descent microphone.
Measured impedance at 1.2KHz at M position:
660Ω,-...
Measure impedance at 1.2KHz at S position
560Ω,12mH
By adjusting L,R with Dunbridge inductor, resistor boxes and trying to match sound and above measurements it seems the Pleiades (R,L) filter used internally for gentle slope low cut is something like:
(1.2KΩ,90mH)
Another nice sounding combination for (R,L) found by listening while singing is:
(>610Ω,100mH)
Signal path:
Male singing voice at various resisters - mic at 9in to 15in - (Pleiades Dunbridge filter) - Sony TC-D5 - Sennheiser HD580 - singer's ears, brain
Comparing with the splendid Shure SM59 it sounds much louder for same REC level setting (one reason being the higher impedance) but the SM59 sounds even more focused and has more of that easy great ribbon microphone treble detail.
It also seems the M534 has more proximity bass boost effect. It's Pleiades (R,L) gentle slope passive low cut filter make it very nice or suitable for singing at say 9in.
