Electret Gooseneck Microphone

The EGM-8N 8” (20 cm), EGM-12N 12” (30.5 cm), and EGM-18N 18” (45.7 cm) electret cardioid microphones are ideally suited
for vocal sound reinforcement, and public address and intercom applications. The unidirectional cardioid response makes them

particularly benecial when background noise is a problem. Each microphone features a self-locking Neutricon connector for
panel mounting, specically selected for use with the previous DKP-8, DKP-12, and KP-12 models.
