Radial Engineering McBoost Microphone Signal Intensifier – Active Mic Gain Booster with Clean Preamp Lift for Low-Output Microphone Signal Enhancement in Studio and Live Use

The Radial Engineering McBoost Microphone Signal Intensifier is a professional active microphone gain booster designed to increase low-output microphone signals with exceptional clarity, low noise, and high headroom in studio, live sound, and broadcast environments.

Built around a Class-A FET amplification circuit, the McBoost provides up to 25 dB of clean gain, making it ideal for passive microphones such as ribbon and dynamic mics that require additional level before reaching a preamp. It effectively strengthens weak mic signals without introducing noticeable distortion or coloration, preserving the natural tone and detail of the source.

A key feature of the McBoost is its load adjustment control, which allows engineers to fine-tune how the microphone interacts with the preamp stage. This helps optimize tonal response, especially for sensitive ribbon microphones. In addition, the unit includes a high-pass filter, which reduces unwanted low-frequency rumble and handling noise, improving clarity in demanding recording or live environments.

As a fully active, high-performance signal booster, the McBoost is designed to sit inline between the microphone and preamp, improving signal strength before it reaches the main mixing console or audio interface. This helps reduce noise floor issues and ensures cleaner gain staging throughout the signal chain.
