Detail 01
Hypercardioid pattern
Narrower front lobe than cardioid with a small rear lobe. More gain before feedback, but aim is less forgiving.

AudixMB5055 MicroBoom-50 With M1255B Microphone Hypercardioid
Independent shopping perspective
The Korena take
A 50-inch carbon fiber boom with a miniaturized hypercardioid condenser, for tight overhead pickup where stage monitors and room sound need rejecting.
Strong match
Who this is for
- Choir or ensemble miking on a loud stage with wedges
- Theater pickup where you need to narrow onto one group
- Rooms with reflective walls that muddy a wider pattern
Consider the trade-offs
When to look elsewhere
- Covering a wide section from a single boom
- Anyone without 18-52V phantom power at the input
- Sources that move around under the capsule
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
50-inch carbon fiber rod, .20 inch diameter
Thin enough to read as a line, not a mic. Gets the capsule over a group without a boom arm in frame.
Detail 03
130dB max SPL, 109dB dynamic range
Handles a full choir or brass section peaking close by without the capsule folding over.
Detail 04
21dB self-noise, 73dB S/N
Quiet enough for distant miking, where you run high gain and the preamp hears everything.
Detail 05
50Hz-19kHz response
Rolls off below 50Hz, which keeps stage rumble and HVAC out of a mic hung in open air.
Detail 06
Mini-XLR at both ends
Capsule and boom detach. Cable runs are mini-XLR, not standard XLR, so plan the connection to your mixer.
Final check
Know before you order
- 01Requires 18-52V phantom power from the mixer or interface
- 02You'll need a stand or mount rated for a 50-inch boom
- 03Hypercardioid has a rear lobe — keep wedges out of the back
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Why pick hypercardioid over the cardioid version?
It rejects more from the sides, so you get more gain before feedback on a loud stage. The trade is a narrower pickup area that needs careful aiming.
02Does it need phantom power?
Yes, 18-52V from your mixer or interface. The condenser capsule will not pass signal without it.
03Will it cover a whole choir?
One boom covers a narrower slice than the cardioid version. Wide groups usually need more than one, spaced across the front.
04What connectors does it use?
3-pin mini-XLR, male at the bottom of the boom and female at the top for the capsule. Not standard full-size XLR.
