Title: Powering microphones
Post by: sasa999 on September 05, 2011, 05:20:04 PM

Does powering voltage affects noise level of condenser microphones? EM172, WM-61a etc...

As I understand it, Powering voltage affects headroom. With more headroom the noise floor is lower, hence quieter.

This is why most people use 9 Volt battery boxes with the WM61a instead of the Plug In Power present on many recorders, (often 2-3 volts.)
