Smaller Omnidirectional microphones and Pleiades Filters


Having said that they do not need a Pleiades filter as they sound less bass heavy on voice...


By using them (MD611, Beyerdynamic M55, Philips N8207...) directly on Sony TCD5 Pro II the sound still need some bass reduction for voice, singing.


On the previous mentioned setup Pleiades filters are not needed because the inexpensive inline input transformer (500Ω-50KΩ) has a primary inductance of only 300mH and plays the role of a Pleiadws transformer. Together with the 500Ω output impedance of those mics they make a very effective low cut filter producing correct balance to listener's brain.
