Buzzing I have a neumann Tlm 193 which one day during a recording session suddenly started buzzing as if a wire was grounding or perhaps touching something. I have not used it since but I would like to. I do not know about wiring inside microphone or where to start with fixing and/or assessing problem.Think you might know?

Poor earth grounding.

Getting the grill fixed or replaced could run you 50-100 bucks.

The Shure SM58 is a dynamic microphone instead of the electret one Neumann TLM 103. This means that Shure does not need a phantom power supply voltage, instead of Neumann TLM 103; this one needs 48Volts. Here are the specifications for each one of the microphones: Shure SM 58 - Neumann TLM 103. In case you use a pre-amplifier or an audio console try to locate a switch marked as "Phantom Power" and turn it on. Typically there is no problem supplying a phantom power at the SM58. In case you have no phantom power switch available, either post back the mixer brand / model to check it for you, or post me a question to suggest you one. Details about the usage and the mixer you are already using will help me to clarify the total audio situation.

In case of a problem or clarification or further details needed, don't hesitate to post me a reply before rejecting my answer.

The wire that is not connected is probably the ground wire. Reconnect it and your humming should stop.

The buzzing may be filter capacitors in the power supply or in the output amp of the sub.

I just solved this problem with my Keurig Plantnum. It seems that the valve that lets the water in is sensitive to clogs or sticking. Or perhaps like me, you have very hard water and calcium is starting to build up. Anyway, what worked for me was filling the resevoire all the way and turning the unit on. Then while the pump was buzzing I lightly jiggled the reseviore and all of the sudden the water level started to go down.

It sounds like you have a bad ground on the tone arm. It's probably time to replace the tone arm wiring, or the external connecting cables.

Several things to try:
- Probably already have, but another guitar cord.
- Ground switch on the amp?
- I had an older guitar that buzzed due to the pickups. While touching the strings, all was well - I was acting as the ground then. The ground wire broke, so it buzzed no matter what. The ground wire ran to the metal bridge.
- Play louder than the buzz! :)

poor grounding.. loose grounding or replace the wire with with the best quality grounding......
