If you need lower noise with 61A, try ......   putting a small sphere or plate around it.
How do you mean  it? Can you give some link for pictures or more explanation?

DPA info on their small sphere mount attachments for omnis- http://www.dpamicrophones.com/en/Mic-University/Technology-Guide/Acoustic-Modification-Accessories.aspx

Regarding the plotted mic tests..  I am curious what your repeatability is.

Specifically, how two back to back test compares.   But also, how two tests compare where you remove the capsule from whatever mounting setup you are using, and then re-mount it.

Have you looked at that?

Taken from http://www.frogloggers.com/BT%20EM172.htm
Operating Voltage 5 VDC (3 to 10V)
CAUTION:
The EM172 ECM must be operated at or near its nominal operating voltage. Operation at too low a
voltage will produce excessive self-noise.


Low voltage shortcomings might not be evident when you record ambient stuff like above, but is probably noticeable in a high SPL situation.

I am trying to order some of the 172s but can't find a seller online.  ???  The frogloggers.com site seems to be take over by a virus.

Will anyone please suggest an online dealer in the USA for these and other Primo mics?  I'd like to buy two or three of each of their omnis.

Thanks. :)
