A way to connect the Sennheiser MD421 HN HL or MD21 HN HL balanced without modifying it

We just assume it is balanced and it may be.


The good news is that the center pin of the microphone is not connected to the metal part of the microphone.


So a cable can be made as follows:


A male Neutrik connector is connected  to a balanced twisted pair cable the normal way. X L R (external live return) ie 1 2 3.


On the other side of the cable:


The central mini Female Tuchel pin is connected to cable return. The live cable is connected normally to the low impedance Tuchel pin.


And the external screen of the cable is connected to the metal part of the mini Tuchel only.


The internal shunt autotrasformer? is a good thing as it electromagnetically damps extremely low frequencies, pop and wind.
