Radial Engineering ProMS2 Passive Microphone Splitter – Transformer-Isolated Dual-Output Mic Splitter for Reliable Signal Distribution in Live and Studio Use

The Radial Engineering ProMS2 Passive Microphone Splitter is a professional transformer-isolated dual-output mic splitting interface designed for dependable signal distribution in live sound, broadcast, and studio environments.

The ProMS2 allows a single microphone input to be split into three outputs: two direct outputs and one fully transformer-isolated output. This configuration gives engineers flexible routing options for sending the same mic signal to multiple destinations such as a front-of-house console, monitor desk, recording system, or broadcast feed—all while maintaining signal integrity and preventing interference between systems.

At the core of the design is a high-quality Eclipse isolation transformer, which provides galvanic isolation on the isolated output. This eliminates ground loops, reduces hum, and ensures clean signal separation when connecting multiple audio systems powered from different sources.

Because it is a fully passive device, the ProMS2 requires no external power and delivers a transparent, natural signal path. It preserves the original tone and dynamics of the microphone while ensuring consistent, noise-free distribution across all connected outputs.

Key Features:

• 1-in / 3-out microphone signal splitter for live and studio applications
• Two direct outputs plus one transformer-isolated output
• Eclipse transformer for effective noise isolation and ground loop elimination
• Fully passive design (no power required)
• Transparent signal path with minimal coloration or signal loss
• Reliable multi-system signal distribution for professional audio setups
• Ideal for live sound, broadcast, theater, and recording environments
