PG81 Cardioid Condenser Instrument Microphone is a professional quality flat-response microphone designed to be used in sensitive acoustic
instrument applications. With rugged durability and excellent sound, this versatile microphone comes with an on/off switch, swivel adapter, carrying
pouch and choice of with XLR cable, or without. Phantom power or included AA battery required.
Flat frequency response is wide and uniform. Consistent sensitivity through frequency range.•
Cardioid polar pattern picks up the most sound from in front of the microphone and some sound from the sides. Less susceptible to feedback in •
high volume settings.
Condenser cartridge has a lightweight, sensitive diaphragm. Precisely and smoothly captures sound nuances.•
Powered by AA battery or phantom power supply.•
Internal shock mount for reduced handling noise.•
Durable metal construction.•
On/off switch for onstage control.•
