Dynamic microphones are the industry standard for live performance. Ruggedly designed, they are able to withstand rough handling and difficult environmental conditions better than their delicate condenser and ribbon element counterparts. Like any piece of electronic equipment, they are susceptible to damage under extreme conditions. Fortunately, they are relatively easy to repair with a little patience and electronic soldering skills.
4 With care and common sense, your dynamic mic will provide many years of reliable service. If you do not desire to undertake repairs on your own, many manufacturers offer express repair service for a flat fee through the mail.Unplug microphone cable from the amplifier before performing work.You must have electronic soldering skills and use a small wattage iron to avoid overheating components, which may cause further damage.
Microphone Troubleshooting - Effective troubleshooting of all electronic equipment is best performed by inspecting obvious components first. If a microphone stops working, swap it with a known working unit. If sound is still not present, change the cable. Ensure that the amplification device is operational, and that the on/off switch is in the "on" position.
