The first one based on the generic principle of generator systems is dynamic microphones.
Dynamic microphones are one of the most common types of detectors.
Dynamic microphones have good acoustic and electric characteristics: sensitivity from 1 mV/Pa, frequency range from 50-100 Hz to 10-15 kHz.
However, dynamic microphones have several drawbacks: difficult and massive construction, relatively low sensitivity, difficulties with forming directional responses, etc.
Housed in a lightweight and ultra-rugged casing with professional connectors, it provides the low noise and high gain (up to + 24 dB) demanded by professional dynamic microphones. Its extremely low power consumption (less than 500 oA) enables long recording sessions and uninterrupted on-air interviews.
