Equipment
Condenser microphone backplate
The rigid conductive plate positioned close to a condenser microphone diaphragm to form a variable capacitor.
The rigid conductive plate positioned close to a condenser microphone diaphragm to form a variable capacitor.
Use cases
- Sound moves the diaphragm and changes its spacing from the backplate, varying the capacitance and producing the audio signal. The capsule design, polarization method, and active impedance-conversion electronics are parts of the microphone’s operating system and should not be confused with its pickup pattern.
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
