Shure
Beta 57A
Dynamic · Supercardioid · 50–16,000 Hz · a rider regular
- The supercardioid instrument Beta: about 5 dB hotter than an SM57 and tighter, with a hardened grille that survives a drummer.
- Same capsule as the Beta 58A behind a different grille — the pair are as closely related as the SM57 and SM58.
Frequency response
No response curve yet.
MicSense only draws a curve traced from a graph the manufacturer actually publishes — it never estimates one from the microphone’s class. Shure publishes figures for the Beta 57A but no response graph, so the numbers are in the spec table below and the chart stays empty.
Polar pattern
Generated from the first-order directivity formula for supercardioid. It illustrates the pattern type — it is not a measurement of this individual model.

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”.
Compare it against the alternatives.
MicSense lets you put up to four microphones side by side — spec table, overlaid response curves and polar diagrams on one screen. Free with a free Squaresmile account.
