Equipment
Electret condenser microphone
A condenser microphone whose capsule uses permanently charged electret material rather than requiring external polarization voltage.
A condenser microphone whose capsule uses permanently charged electret material rather than requiring external polarization voltage.
Use cases
- The electret maintains the capsule’s charge, but active electronics still require power, which may come from a battery, plug-in power, bias supplied by a compatible transmitter, or phantom-powered circuitry depending on the design. Connector shape alone does not establish the correct powering method.
Setup
- Confirm the intended use, inspect the equipment, and coordinate placement with the responsible department.
Safety notes
- Use only within manufacturer ratings and the production safety plan.
In practice
