Audix MB8450 Miniaturized Condenser Microphone w/84" Carbon Fiber Boom

The Audix MB8450
The Audix MB8450 is a MicroBoom™ System built around an 84″ (2134 mm) carbon fiber boom paired with the M1250B cardioid condenser microphone. Designed, assembled, and tested by Audix in the USA, it's engineered to solve difficult miking situations where a standard microphone stand simply can't reach — think choir risers, sprawling ensemble vocal setups, theatrical staging, or wide orchestral zones. The system pairs a lightweight, rigid boom with a precision-engineered microphone to deliver a clean signal path and an unobtrusive stage presence, all while remaining easy to mount on any standard microphone stand.

Design and Build
The MB8450 is defined by its carbon fiber construction — a material chosen for being both remarkably lightweight and structurally rigid, letting the 84″ boom extend far into a performance space without sagging or wobbling. Internally, high-quality shielded cable runs the full length of the boom, protecting the audio signal from interference between the capsule and the connector at the base. A flexible metal gooseneck sits at the stand adapter, giving engineers total control over the angle, rotation, and position of the boom, so the microphone can be aimed precisely at its target without needing to reposition the entire stand. The result is a rig that looks clean and elegant on stage — an important consideration for choir and theatrical productions where visible hardware can be distracting — while still delivering professional-grade performance.
Microphone and Signal Path
At the working end of the boom sits the M1250B, a cardioid condenser capsule chosen for its focused pickup pattern, which helps isolate the intended sound source from surrounding stage noise. The microphone requires 18–52V phantom power, supplied through the console or preamp rather than an internal battery, which keeps the boom assembly itself free of any external power components. The included windscreen helps minimize plosives and wind noise, particularly useful for vocal and choral applications where singers may be close to the capsule. Because the MB8450 is part of the broader Micros™ series, users benefit from a signal chain that's consistent with Audix's other miniature microphone offerings, should a production need to standardize gear across multiple pickup points.
Versatility and Application
What sets the MB8450 apart is its adaptability across performance contexts. Whether it's positioned over a choir for even ensemble pickup, angled toward a theatrical stage for dialogue and vocal reinforcement, or placed to capture a section of an orchestra, the boom's reach and adjustability let sound engineers solve placement challenges that fixed stands can't. It's available in black or white finishes, allowing it to blend into different stage aesthetics, and its portability means it can be broken down and moved between venues without extensive rerigging. Combined with the clutch assembly for secure stand mounting and the 25′ shielded cable for routing flexibility, the MB8450 offers a complete, ready-to-deploy solution for hard-to-reach miking applications.
Why We Love This
Our gear experts appreciate the MB8450 because it solves real staging problems without cluttering the performance space. Its 84″ carbon fiber boom reaches choir risers, orchestral sections, and theatrical staging that standard stands can't cover, while the flexible gooseneck allows precise aiming without repositioning. The clean, elegant appearance keeps focus on the performance rather than the hardware. Combined with a high-quality shielded internal cable and reliable cardioid capsule, it delivers professional, consistent audio pickup performers and engineers can depend on.
