Audix MB2455HC - MicroBoom System with Hypercardioid Condenser Microphone (61 cm)
The Audix MB2455HC represents the perfect fusion of visual discretion and auditory excellence. This professional system, known as MicroBoom™ , integrates a high-tech 24-inch (approximately 610 mm) carbon fiber boom arm with the acclaimed M1255B-HC miniature condenser microphone. Designed to overcome the most common challenges in long-distance audio capture, this equipment offers an elegant and effective solution for scenarios where aesthetics are as important as sound quality.
Unlike traditional microphone stands that can be bulky and obstructive, the MB2455HC system stands out for its ultra-slim profile and featherweight design. The carbon fiber boom arm is not only exceptionally rigid and durable, but it also houses a high-quality shielded cable internally, ensuring clean, interference-free signal transmission from the capsule to the final connection. This all-in-one design eliminates visible cable clutter and allows for quick and clean installation in any environment, from hallowed auditoriums to television studios.
The heart of this system is the M1255B hypercardioid microphone. This pre-polarized condenser capsule features a fully integrated, miniaturized preamp, enabling it to deliver superior sensitivity and very low noise. Its hypercardioid polar pattern is critical for critical applications, providing exceptional isolation of the desired sound source by effectively rejecting ambient noise and other nearby instruments, resulting in a cleaner mix and higher gain before feedback.
Main features
-
Carbon Fiber Construction: The 610mm MicroBoom rod is incredibly lightweight (less than 80 grams without the mic) yet robust, ensuring the microphone remains stable without bending.
-
M1255B Hypercardioid Capsule: Offers precise and focused pickup, ideal for isolating voices or instruments in acoustically complex environments.
-
Integrated Preamplifier: Unlike other miniature microphones, the M1255B houses its electronics within the body itself, eliminating the need for bulky external power packs.
-
Interference Immunity: Designed to resist radio frequency (RF) interference caused by mobile phones and GSM devices.
-
Versatile Installation: It attaches to any standard microphone stand, allowing precise angle and position adjustments thanks to its metal "clutch" adapter.
Product benefits
For sound engineers and stage managers, the Audix MB2455HC is a natural problem solver. Its main advantage lies in its near-invisibility : it can capture the sound of a choir or orchestra from above or the front without obstructing the audience's view or video cameras. Furthermore, its high output sensitivity allows for long cable runs without signal loss, making it ideal for use in large theaters or auditoriums.
The audio quality is studio-grade, capturing nuances and transients with crystal clarity. Being a modular system, the capsule can be swapped out if needs change, but the included hypercardioid configuration is perfect for maximizing control over what is picked up and what is rejected.
Use cases
-
Choirs and Vocal Groups: Ideal for overhead microphones where it is necessary to capture the set of voices in a balanced and discreet manner.
-
Theatre and Opera: Perfect for placing on the edge of the stage or suspended, capturing dialogue and singing without interfering with the scenery.
-
Acoustic Instruments: Excellent for miking string sections, woodwinds or orchestral percussion from a moderate distance, maintaining a natural sound.
-
Presentations and Conferences: An elegant alternative to traditional gooseneck microphones on podiums or discussion tables.
-
Places of Worship: Their minimalist design respects the aesthetics of the altar or sanctuary while ensuring that the spoken or sung word reaches the congregation clearly.
Frequently Asked Questions
-
Does it need phantom power?
Yes, the included M1255B-HC microphone is a condenser microphone that requires 18 to 52 Volt phantom power to function properly.
-
What is the length of the arm?
The MB2455HC model features a 24-inch rod, which is approximately 61 centimeters in length.
-
Does the system include the microphone stand?
No, the system includes the MicroBoom boom arm, microphone, stand adapter, and cable, but it's designed to attach to any standard microphone stand you already own.
-
Can the microphone capsule be changed?
Yes, the MicroBoom system is modular and compatible with other Audix Micros series capsules if you need a different polar pattern (such as omnidirectional or cardioid) in the future.
Project description
Low-profile condenser microphone system consisting of a 610 mm (24") long, 7.4 mm diameter carbon fiber boom arm coupled to a miniature hypercardioid microphone. The microphone offers a frequency response of 50 Hz to 19 kHz, an impedance of 150 ohms, and a sensitivity of 32 mV/Pa @ 1 kHz. The system integrates an internally shielded cable terminating in a male mini-XLR connector at the base of the boom arm and includes a 7.5-meter female mini-XLR to male XLR adapter cable. The assembly weighs less than 100 grams and requires 18-52 V phantom power. A stand adapter with angle adjustment and a windscreen are also included.
