Wireworks MBX27 Series 27-Pin Transformer Isolated Microphone Splitter Stagebox

The Wireworks MBX27 Series 27-Pin transformer isolated microphone splitter stagebox is a critical piece of professional audio infrastructure designed for flawless signal distribution in demanding live sound and broadcast environments. Its primary function is to accept a bank of microphone-level signals from a stage or performance area and split each signal into multiple, electrically isolated copies without any degradation in quality or the introduction of noise. The unit is housed in a rugged, road-ready stagebox that terminates in a standard 27-pin multi-pin connector, facilitating rapid setup and strike through a single, robust cable run to front-of-house or broadcast positions. This design is essential in complex multi-system setups where the same microphones must feed separate mixing consoles for front-of-house, monitor mixing, broadcast, and recording simultaneously.

The core technical achievement of this device lies in its use of high-quality, discrete audio transformers for each channel. This transformer isolation creates a galvanic barrier between the input and each output, effectively preventing ground loops that cause hum and buzz, while also blocking dangerous DC voltage and phantom power from traveling between connected consoles. This protects sensitive equipment and ensures that phantom power from one console does not interfere with another. The result is complete electrical separation, allowing each receiving console to operate independently with its own gain structure and phantom power requirements, all while deriving a clean, identical signal from the original source.

Constructed with durability and reliability as paramount concerns, the stagebox features heavy-gauge steel chassis, Neutrik connectors, and internally wired components that can withstand the physical demands of touring. The layout is intuitively designed for audio technicians, with clear channel numbering and status indicators. By centralizing the splitting function at the source, the MBX27 Series dramatically reduces stage clutter and cable runs, improves system reliability, and delivers unmatched signal integrity. It is the preferred solution in theaters, touring sound rigs, and permanent installations where absolute audio fidelity and system flexibility are non-negotiable.
