How To Repair Neumann Xlr Connector Assembley For Kms 105

FIX: Neumann KMS 105

Inconsistent sound indicate from your KMS105? The fix might be really uncomplicated. Here'due south how I fixed 1.

My wife Katie Nelson and I both utilize Neumann KMS 105 condenser microphones for live operation. Nosotros love how the microphones audio and trust the Neumann brand.

The Problem

Recently Katie'south microphone was passing audio inconsistently. Sometimes it was normal, sometimes the output volume was quieter, and sometimes it would crackle equally if the XLR cable was bad.

I chosen Sennheiser, the parent company of Neumann, to inquire near repairs. They connected me directly with a bench technician who kindly asked questions about the symptoms so walked me through the fix. He correctly suspected that the hex screws holding the capsule to the internal printed excursion lath (PCB) were loose. In fact, the capsule was completely disconnected from the PCB. I was surprised that the microphone worked at all because at that place was almost no contact between the sheathing and PCB.

PRO TIP: Microphones work best when the sheathing is physically connected. #signalflow

The Fix

Take out the car spiral on the side of the microphone that holds the XLR insert in place. There may be a small lock washer underneath the screw. Set up them aside.
Unscrew the basket (or grille, as people frequently refer to it).
Slide off the black capsule encompass screen.
Very carefully pull on the sheathing while simultaneously pushing on the XLR insert. Warning: BE VERY CAREFUL WITH THIS STEP. THE PCB HAS A SERIES OF WAVY CUTS IN IT. TOO MUCH PUSHING OR PULLING CAN Interruption THE PCB. GO Irksome. GO EASY.
Pull back the safe band around the brass capsule torso. Remember the orientation of the ring in reference to the notch in the body.
Confirm that leap is seated properly on the capsule eye pin.
Push the sheathing body onto the PCB until fully seated. The hex screws should exist positioned over the solder-tinned holes.
While belongings the capsule and PCB together in that position, use a 0.035″ (0.89mm) hex key to tighten down the tiny set screws.
Supercede the rubber ring. Brand sure the orientation of the ring fits into the notch in the body.
Carefully insert the assembly back into the body. Again, be very conscientious. You will likely demand pocket-size pliers/grips/etc. to pull the XLR insert all the style into position while simultaneously pushing the capsule into the body.
Tighten the spiral through the body into the XLR insert.
Slide the capsule encompass screen onto the sheathing.
Screw the basket onto the body.
Test the microphone. If you still are experiencing audio problems, contact Sennheiser for service.

Fiddling parts are easy to break. Exist specially conscientious with this section.
