Externally polarized microphones were the original standard for all test and measurement acoustic applications. This design utilizes a separate 200V power supply and special cables with 7 pin LEMO® connectors. Their simple design enables a large product offering. These microphones are commonly used to replace existing externally polarized microphones, or in cases where a prepolarized alternative is not available.
