Topic: Sennheiser MKE-40s / MM-HLSC-1

[hyperplane]

All right, i know several people here (including myself) have been sharing PMs regarding these mics. so i thought it would be nice to compile the knowledge, speculations, etc. all in one thread if possible.

a friend of mine loaned his Microphone Madness MM-HLSC-1s (which have Sennheiser MKE-40 capsules) to me. i removed the housing and found that the cable is indeed 3 wires.

i'm wondering if these mics would benefit from the 3-wire mod that has gained some popularity here. unfortunately, my friend's mics are apparently defective (left mic capsule distorts with moderate bass levels), so i cannot fairly test them out with a typical 2-wire (9V powered) battery box.

also, as i said to a fellow TS member: FWIW, inside the mic capsule, near where the positive and power wires are soldered, is a small brown rectangular piece of plastic with the number J35.


pics of the mic capsule/cable, with housing removed, to come.


EDIT: to add pics (sorry, the pictures are blurry! will try to take better ones when i get the mics back from MicrophoneMadness).


the first pic shows one side of the capsule, with shield/ground wire soldered to the "rim" of the capsule.

the second pic shows the other side of the capsule, with the audio and power wires soldered to the "inner" part of the capsule. the red (power?) and white (audio?) wires are approximately 1 mm apart.

Did you check for continuity between the wires to see that there is no short?
MM pricing is interesting. Does the clip work well for stealth?

explain the meaning of "continuity between wires"....

Resistance is zero Ohms? (not my native language)
If all wires and shield are separate one could try the 3-wire method.

MM says they currenlty deliver only 2-wire version.

VERY interesting info. thanks for posting that, udovdh.

as soon as i get the mics back from MM, i will try to take better pictures, and hopefully we can see if the mics are wired for signal/shield or can be modified for 3-wire powering.

+T for the naked mics!

The J35 is probably a FET.

Please take better pictures.  Those same views, but just clearer.  I want to see this capsule!  Perhaps you can move the camera farther away and use the zoom.  This might work better.  Camera people may suggest something too...

Sennheiser can deliver in 3-wire version. Getting a 3-wire pair from MM would be interesting. I do have a 2-wire set. They have red/blue wires plus shield on a Lemo coaxial.
I asked MM for a 3-wire version. Maybe more people should do this?

+T for that PDF file, udov!



Richard - will send you a PM shortly.

Still looking into ways of implementing this mic the best way possible.
Please see this thread. Things to think about are maybe terminating impedance, gain setting via the resistor, etc.
