Panasonic Condenser Microphone Cartridge (WM-60AT)
The Panasonic Condenser Microphone Cartridge consists of
a high voltage internal electret membrane, metal electrode and a field
effect transistor (FET). Doesn't need a high-voltage bias from the
outside like ordinary condenser microphones.
- Highly efficient electrical specification, pressure type
operating principle, low impedance (2.2 kOhm), omnidirectional back
directivity, and a high degree of reliability under adverse shock,
vibration and environmental tests.
