Shure
KSM44A
Large-diaphragm condenser · Cardioid / Omnidirectional / Figure-8 · 20–20,000 Hz
Discontinued since 2 Oct 2026 — Shure no longer lists the KSM44A as a current product. The figures stay here for the units still in use.
- Three switchable patterns, a 15 dB pad and a two-stage low-cut, all on the body.
- An externally biased (true) condenser rather than an electret — the distinction that separates the KSM range from the Beta condensers.
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 KSM44A yet, so the numbers are in the spec table below.
Polar pattern
Generated from the first-order directivity formula for cardioid / omnidirectional / figure-8. It illustrates the pattern type — it is not a measurement of this individual model.

Specifications: Shure datasheet · 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
- Choir / ensemble
- 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”.
KSM44A 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 KSM44A’s for the same live job, with the reasons. It says nothing about how they sound.
