Detail 01
Supercardioid pattern
Tighter front pickup than cardioid, but it picks up some sound directly behind, so keep monitors off the rear axis.

Heil SoundPR 30B Large-Diaphragm Dynamic Microphone Black
1/8
Independent shopping perspective
The Korena take
A 299 dollar supercardioid dynamic with a 1.5-inch element, built for broadcast voice, guitar cabs and loud sources where off-axis rejection matters.
Strong match
Who this is for
- Spoken voice into a mic arm on a desk
- Close-miking a loud guitar cabinet on stage
- Rooms with untreated walls and background noise
Consider the trade-offs
When to look elsewhere
- Anyone wanting airy top end above 18kHz on vocals
- Wide-source recording where a cardioid pattern captures more naturally
- Players who need phantom-powered condenser sensitivity for quiet sources
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
1-1/2 inch dynamic element
A larger diaphragm than most handhelds; moves more air at low frequencies and gives voices weight up close.
Detail 03
40Hz to 18kHz response
Reaches lower and higher than a typical stage dynamic, so it needs less EQ to sound full and open.
Detail 04
-52.9dB output level
A quiet output. You'll need a preamp with plenty of clean gain, especially on soft speech.
Detail 05
600 ohm balanced output
Standard low impedance. Works with any XLR preamp and tolerates long cable runs without losing highs.
Detail 06
Steel case, 9 oz
Heavy enough to demand a real boom arm or sturdy stand. Light desk arms will droop.
Final check
Know before you order
- 01Needs a mic preamp with high clean gain; no phantom power required
- 02No stand, boom arm, shockmount or XLR cable in the box
- 0315/16 inch stem diameter, so check your mount hardware fits
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Does the PR 30B need phantom power?
No. It's a dynamic microphone, so it generates its own signal. Phantom power won't damage it, but it does nothing. What it does need is a preamp with plenty of clean gain.
02Can I plug it straight into a computer?
Not directly. It's an XLR mic with 600 ohm balanced output, so you need an audio interface or mixer with an XLR preamp between the mic and the computer.
03What's the difference between supercardioid and cardioid here?
Supercardioid narrows the front pickup angle and rejects sound from the sides more sharply, but adds a small rear lobe. Point the back of the mic away from monitors, not the sides.
04Is it good for loud sources like guitar cabs?
Yes. It's a dynamic with a large element and a 40Hz-18kHz range, which suits close-miking loud amplifiers where a condenser would be overwhelmed.
