Audix M1255B - High Output Miniaturized Condenser Microphone (Black)
The Audix M1255B redefines what's possible in the world of professional installation and studio microphones. Part of the acclaimed The Micros™ series, this device is more than just a small microphone; it's an advanced engineering solution designed to capture high-fidelity audio from considerable distances without sacrificing aesthetics or signal quality. Measuring just 54 mm in length, the M1255B blends almost seamlessly into any environment, from corporate boardrooms to demanding concert stages.
What truly sets the M1255B apart from other surface microphones is its fully integrated preamp . Unlike other models that require bulky external power modules, all the necessary electronics are contained within the microphone's machined brass body. This, combined with exceptionally high sensitivity, allows for crystal-clear and powerful sound pickup, ideal for distant sources such as choirs or speakers who are not directly in front of the microphone.
Signal integrity is guaranteed thanks to Audix's patented RF immunity technology. In a world saturated with mobile devices and wireless networks, the M1255B operates free from annoying radio frequency interference and GSM hum, ensuring pristine recording or transmission. It comes standard with a cardioid capsule, but its modular design allows for unparalleled versatility to adapt to any acoustic challenge.
Main features
-
Ultra-Miniature Design: With a discreet and elegant black profile, it is perfect for applications where the microphone needs to be heard but not seen.
-
Integrated Preamplifier: Miniaturized, low-noise electronics housed internally, eliminating the need for external power supply boxes and simplifying installation.
-
High Sensitivity (High Output): Designed specifically for "distant miking", capturing sound sources with clarity and detail even when the microphone is far from the source (such as on ceilings or overhead setups).
-
CommShield® Technology: Advanced shielding that protects the signal against RF interference caused by mobile phones, GSM devices, and Wi-Fi.
-
Robust Construction: Body made of CNC machined brass with a durable finish, designed to withstand continuous professional use.
-
Modular Flexibility: Although it includes a cardioid capsule, the system is compatible with interchangeable capsules (hypercardioid, omnidirectional, and shotgun) to adjust the polar pattern as needed.
Benefits for the user
The M1255B offers a professional plug-and-play solution for sound installers and technicians. Its ability to handle high sound pressure levels (SPL) of up to 130 dB makes it equally suitable for recording loud acoustic instruments or capturing the subtleties of a human voice in a conference. The inclusion of a high-quality 7.6-meter (25-foot) cable allows for immediate mounting on ceilings or high stands without the need for additional splicing.
For architects and interior designers, this microphone respects the visual aesthetic of the space, blending seamlessly into its surroundings thanks to its size and matte finish. For audio engineers, the signal purity and low equivalent noise level (21 dB) mean less time processing and cleaning tracks and more time mixing.
Ideal use cases
-
Conference and Meeting Rooms: Ceiling or table mounting to capture clear voices from all participants without cluttering the table with large equipment.
-
Choirs and Vocal Groups: Overhead placement to capture the full ensemble with balance and naturalness.
-
Theaters and Stages: Ambient microphones to capture the audience's reaction or discreet microphones on the stage for plays.
-
Acoustic Instruments: Excellent for guitars, orchestral percussion, cymbals and piano, where a fast attack and flat frequency response are required.
-
Education and Classrooms: Recruitment of teachers or students in hybrid or distance learning environments.
Frequently Asked Questions
-
Does this microphone need power?
Yes, the M1255B is a condenser microphone and requires phantom power (18-52V) from the mixing console or interface to operate its built-in preamp.
-
Can I change the microphone's polar pattern?
The base M1255B model comes with a cardioid capsule. However, the capsules are modular and can be swapped for hypercardioid, omnidirectional, or shotgun versions (sold separately or in model-specific variants).
-
What type of connector does the microphone use?
The microphone body has a 3-pin male mini-XLR connector. A 7.6-meter cable is included that converts this connection to a standard male XLR for connecting to any professional audio equipment.
-
Is it suitable for recording loud instruments like drums?
Yes, it can handle up to 130 dB of sound pressure, making it suitable for drum overheads, percussion, and other instruments with strong transients.
