Detail 01
28Hz to 18kHz response
Reaches genuine sub-bass territory. That extra low octave is the main practical difference from the PR 30.

Heil SoundPR40 Large-Diaphragm Multipurpose Dynamic Microphone
1/4
Independent shopping perspective
The Korena take
A $379 large-diaphragm dynamic mic with extended low end. For broadcast voice, kick drum and bass cabs where you want weight below what most dynamics reach.
Strong match
Who this is for
- Broadcast and podcast voice that needs real low-end body
- Kick drum, bass cabinets and low brass close up
- Untreated rooms where a condenser picks up too much reflection
Consider the trade-offs
When to look elsewhere
- Distant or ambient room miking — it wants to be close
- Thin, bright sources that would only get heavier
- Setups with a noisy or low-gain preamp
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
End fire, cardioid
Address the end of the mic, not the side. Front pickup with strong rejection behind.
Detail 03
Uniform front-to-back discrimination
Sound arriving off-axis stays natural instead of hollow, so bleed and room reflections sit less obtrusively in a mix.
Detail 04
-53.9dB output at 1kHz
Low output. Expect to run a preamp fairly hot, so preamp noise floor matters more than with a condenser.
Detail 05
Neodymium magnet, low-mass aluminum diaphragm
Strong magnet and light diaphragm give more output and faster transient response than a typical dynamic design.
Detail 06
1 lb steel body with zinc bottom ring
Heavy and solid. It resists handling noise but needs a stand or arm rated to hold a pound steady.
Final check
Know before you order
- 01No shockmount, stand, boom arm or XLR cable is included
- 02Needs no phantom power, but does need a clean high-gain preamp
- 03At 1 lb, light desk arms and small tripod stands will droop
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Does the PR40 need phantom power?
No. It is a passive dynamic mic. Phantom power is neither required nor harmful, and makes no difference to its output.
02What is the difference between the PR40 and PR 30?
The PR40 goes down to 28Hz against the PR 30's 40Hz, and costs $80 more. That low extension is what you pay for.
03Is the PR40 good for kick drum?
Yes. The 28Hz low-end reach and cardioid rejection suit close kick miking, where sub weight and isolation from cymbals both matter.
04Will it work on a boom arm?
Yes, if the arm is rated for a pound and its mount fits the mic's thread. Lighter desk arms sag under this weight.
