OM7
Dynamic · Hypercardioid · 48–19,000 Hz
- 0.8 mV/Pa — deliberately about 10 dB quieter than an SM58, so the wedge behind it can be a lot louder before it rings.
- The mic engineers reach for when the singer wants stage volume nobody can otherwise survive; it needs gain most desks have and some preamps do not.
- Hypercardioid with the tightest published pattern of any common handheld: rewarding on a screamer, unforgiving of a wanderer.
Frequency response
Read off Audix’s published response graph and re-drawn on the fixed MicSense scale (20 Hz–20 kHz, −20 to +15 dB), so two microphones can be compared at a glance. Points between the entered coordinates are interpolated — no data has been invented to smooth the curve.
Polar pattern
Generated from the first-order directivity formula for hypercardioid. It illustrates the pattern type — it is not a measurement of this individual model.

What it gets used for
- FOH vocal
- Monitor vocal
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.
