Help with Sennheiser 421
Hi there folks,
I'm looking for help with a vintage MD-421 N, serial number 139696. The three-pin (mini-XLR?) connector has come loose, and the 5-posititon selector switch has been stripped (spins freely, but still operates). The three wires have come undone from their pins. I can solder them myself if I know the pinout. One wire is red, one is blue, and one is black. Any help would be appreciated. Thanks!

You have to visit the sen. website and request the paper on that sucker
and find out which one is hot, cold, and ground. Or, get a continuity tester at radio shack. |

DIN (Deutche Industrie Norm), what fits as a screw on is a female plug called a minitüchel, Sennheiser has them, they are preferable to use on the mic end of the cable. connector has come loose, and the 5-posititon selector switch has been stripped (spins freely, but still operates). This might, might mind ya, mean that the locking screw - under the serial number badge - is loose or missing. The three wires have come undone from their pins. I can solder them myself if I know the pinout. On my recollection of this, it may be erroneus 1) hot 3) return 2) ground One wire is red, Probably hot one is blue, Probably return and one is black. Probably ground. Any help would be appreciated. Call or email Sennheiser North America for exact info and to get the mic end plug for the cable. Be aware that the connection numbering and number-allocation differs from the XLR defaults, and from all variation thereof. Sennheiser may also be able to supply a rear end that allows you to skip the frequency response altering thingie and to use XLR's on it, it is "only" about fitting the mic with the large tüchel rear end and then fit an xlr-adapter to that one, if it is avaiable. Kinovox here in Denmark modded my 421's like that back in the late 1970'ties, but it may have been with non-standard parts of their own manufacturing. Do not expect it to sound like a version 2 .... and the frequency response got a lot smoother during the manufacturing life of version 1. Some old 421's end up suffering from membrane rigidity syndrome and loose all bass - perfect if you need to emulate a telephone, but useless for anything else, verify that this has not happened prior to using too much money on it.
