Beyerdynamic M 55 LM or K Microphones

The newer black versions have been tested too. The LM is terminated with a 3 pin DIN and the K with a 1/4in. They are 500Ω too.


It is hard to believe how good all the Eugen Beyer M55 microphones (including the older ones) sound.


You would think that you are dreaming.


The M55 HN might have sounded less full and loud but this seems to be because they are 200Ω and they would sing with an input transformer of 1:20 or more rather than the 1:10 or more used on the 500Ω versions.


Setup, signal path:


Male singing at 1 in - Beyerdynamic M55 LM - Canford impedance converter XJ (input transformer with 400mH primary inductance) - Pleiades V4  (the EF183 electron tube 3.4V battery operated) - Realistic disco mixer mono mic in - Sennheiser HD580 precision
