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.
