ELECTRET CONDENSER MICROPHONES

Uni-directional

Uni-directional microphones are designed with both sides of the diaphragm open to the air and mainly pick up sounds from one direction, relatively dead on the other. Typical uses for unidirectional microphones include vocals at live music performances and speeches in front of a large number of people.
