The MPA 002 is a high performance Electret Microphone assembled into a rugged, compact package along with a matched compensation preamplifier. The preamplifier assures an essentially flat transducer response from 240 Hz to 4000 Hz, while providing approximately 20 dB of voltage gain. The enclosure is 100% metal construction, providing a high degree of shielding integrity.
Each assembly is 100% tested for conformance to the MIN./MAX. specification limits at 25°C.
Low power consumption:
Low Output Impedance:
Compact, fully shielded package.
Pigtail Leads for custom installations.
May be powered from unregulated battery supply.
