PG81 Cardioid Condenser Instrument Microphone
Overview
Features
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.•
