Shure PG81 Instrument Microphone w/ XLR Cable:

A sensitive, flat response condenser microphone ideal for acoustic instruments.

PG81-XLR includes a 15ft (4.57m) XLR to XLR Cable, Microphone Clip, 5/8" to 3/8" Thread Adapter, and a Storage Bag.

PG81-LC includes a Microphone Clip, 5/8" to 3/8" Thread Adapter and a Storage Bag.


  • 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.
