Shure
PGA27
Large-diaphragm condenser · Cardioid · 20–20,000 Hz
- A large-diaphragm condenser at the entry end of Shure's range, with 17.8 mV/Pa of output.
- 453 g of it, which on a cheap boom arm is the part that gives.
Frequency response
No response curve yet.
MicSense only draws a curve redrawn from a graph the manufacturer publishes — it never estimates one from the microphone’s class. No published graph has been redrawn for the PGA27 yet, so the numbers are in the spec table below.
Polar pattern
Generated from the first-order directivity formula for cardioid. It illustrates the pattern type — it is not a measurement of this individual model.

Specifications: Shure specifications page · last checked 2 Oct 2026. These are the maker’s published figures for this model. A dash never means zero: “not published by the maker” means the maker’s documents give no figure; “not yet checked” means MicSense has not confirmed one yet. Spotted an error? Tell us.

What it gets used for
- FOH vocal
- Acoustic instrument
- Overhead
MicSense tags microphones by the job on a live stage, not by studio category — so you can filter for “kick in” or “monitor vocal” instead of working backwards from “large-diaphragm condenser”.
PGA27 alternatives: closest in published specs
Based on published specifications only — always listen at soundcheck. These are the microphones in the MicSense library whose datasheet figures sit closest to the Shure PGA27’s for the same live job, with the reasons. It says nothing about how they sound.
