Audix M1255BWHC - Miniaturized Hypercardioid Condenser Microphone (White)
The Audix M1255BWHC represents the pinnacle of professional audio miniaturization technology. This compact condenser microphone is distinguished by its elegant white finish and hypercardioid capsule pattern, designed specifically for installations where aesthetics and acoustic accuracy are equally critical. Unlike other microphones in its class, the M1255BWHC integrates a fully functional preamplifier within its machined brass chassis, eliminating the need for bulky external power modules and facilitating a clean and discreet installation.
Engineered to capture sound sources from a distance with crystal clarity, this model stands out for its high sensitivity and ability to handle long cable lengths without signal loss. It's the ultimate solution for demanding remote microphone applications, such as recording choirs, conferences in large halls, or ambient sound, where pure, noise-free audio is essential.
Main features
-
Total RF Immunity: Equipped with advanced shielding that makes it completely immune to radio frequency interference caused by mobile phones, GSM devices and wireless networks, guaranteeing a clean signal at all times.
-
Miniaturized design with integrated preamplifier: At only 54 mm in length, it houses all the necessary electronics, allowing for an extremely low and discreet profile.
-
High-precision hypercardioid capsule: Offers a narrow pickup pattern that isolates the desired sound source, providing excellent off-axis noise rejection and higher gain before feedback.
-
Robust and aesthetic construction: Made of machined brass with a durable, high-quality white finish, ideal for visually integrating into light ceilings, modern architectural environments, or liturgical vestments.
-
Mounting versatility: Compatible with a wide range of accessories (clips, MicroBoom™ carbon fiber arms), making it easy to use on ceilings, tables, floor stands or overhead hanging.
Benefits for professional audio and installations
The M1255BWHC is more than just a microphone; it's a problem-solving tool for engineers and system designers. Its 12mm gold vapor diaphragm captures fast transients and subtle nuances with a wide frequency response of 50 Hz to 19 kHz. For integrators, the ability to use long cables without signal degradation simplifies cabling in large auditoriums and theaters. Furthermore, its white finish makes it a preferred choice for houses of worship and high-profile conference rooms where technical equipment needs to be invisible to the audience and cameras.
Ideal use cases
-
Choir and vocal group capture: Its hypercardioid pattern allows capturing specific voices in a large group without picking up excessive ambient noise from the room.
-
Videoconferencing and meeting rooms: Perfect for ceiling or table mounting, capturing clear voices from participants without picking up noise from the air conditioning system or projectors.
-
Theaters and Stages: Ideal for ambient microphones, audience capture or acoustic instruments from a distance.
-
Acoustic Instruments: Excellent for overhead cymbals, orchestral percussion, and acoustic guitars where a natural and detailed sound is desired.
-
Broadcasting: Its RF immunity makes it indispensable in TV and radio studios where multiple wireless devices are operating simultaneously.
Frequently Asked Questions
-
Does this microphone need phantom power?
Yes, the M1255BWHC requires 18 to 52V phantom power to operate its built-in preamplifier and bias the capsule.
-
Can the microphone capsule be changed?
The M1255B is a modular system. Although this specific model (WHC) comes with the white hypercardioid capsule, it is compatible with other capsules in the series (cardioid, omni, shotgun) if purchased separately.
-
What advantages does the hypercardioid pattern have over the cardioid pattern?
The hypercardioid pattern is more directional, meaning it "hears" less from the sides. This is crucial in noisy or reverberant environments to better isolate the sound source and avoid feedback.
-
Is the cable fixed or detachable?
The microphone features a male mini-XLR connector at the base and comes with a detachable 25-foot (approx. 7.6 meters) cable that terminates in a standard male XLR connector.
Project description
The microphone will be a miniaturized, pre-polarized condenser microphone with a fully integrated preamplifier and a white finish. It will operate with a hypercardioid polar pattern for superior directional control and off-axis noise rejection. The frequency response will be 50 Hz to 19 kHz, with an output impedance of 150 ohms and a sensitivity of 32 mV/Pa @ 1kΩ. It must have complete immunity to radio frequency interference (RFI) from GSM devices. The chassis will be machined brass with dimensions no greater than 12 mm in diameter and 54 mm in length, and a weight of 16 grams. It will require 18-52 V phantom power. The connector will be a 3-pin mini-XLR. The reference model will be the Audix M1255BWHC.
