AudixMB5055 MicroBoom-50 With M1255B Microphone Cardioid
Independent shopping perspective
The Korena take
A 50-inch carbon fiber boom with a miniaturized cardioid condenser on the end, for hanging or standing choir, orchestra and stage-front pickup.
Strong match
Who this is for
- Choir loft or riser pickup from a stand behind the group
- Theater and orchestra pit miking where the rig must disappear
- Houses of worship needing broad, even pickup of a section
Consider the trade-offs
When to look elsewhere
- Close-miking a single voice or instrument
- Anyone without 18-52V phantom power at the input
- Handheld, podium or run-and-gun use
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
- 03Distant miking means more gain and more room in the sound
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I use this without phantom power?
No. The condenser capsule needs 18-52V phantom from your mixer or interface to work at all.
02Cardioid or hypercardioid version?
Cardioid covers a wider area in front, so it's more forgiving for a spread-out group. Hypercardioid is tighter and rejects more from the sides.
03How does it connect to my board?
Both ends are 3-pin mini-XLR: male at the bottom of the boom, female at the top for the capsule. Plan your run accordingly.
04How loud a source can it take?
130dB max SPL at 5% THD, so a full choir, brass or drums at normal miking distance is not a problem.
