Dynamic microphones will generally stand up to extreme environmental conditions such as temperatures from - 25 °C to +70 °C and high humidity.
Condenser microphones, however, are susceptible to humidity and condensation. When an object is damp and colder than its environment, condensation water will form on its surface. Drops of condensation water inside the transducer or high-impedance preamplifier will cause crackling noises.
Storing condenser microphones:
1. Store the microphone in a dry and warm place. It should never be colder than its environment. If it has been transported in a cold car or van, allow it to warm up before use.
2. The supplied silica gel absorbs humidity. It will maintain this property as long as you keep it in the sealed package and may be regenerated in the oven if necessary.
3. Be sure to protect condenser microphones from rain when using them outdoors. |
