The McBoost from Radial is a high-quality microphone signal booster designed to elevate an output signal of a dynamic microphone or low-output ribbon mic and bring it up to a usable level for mixing consoles and preamps. It can be used for applications such as recording, broadcast TV, rehearsals, live stage, and more.

The 100% discrete class-A design features a dual-transistor J-FET circuit that produces up to 25 dB of gain via a 48V phantom power source without introducing noise, color, or artifacts. Measuring each individual transistor carefully, which is batch-sorted to certify performance, the circuit board is then placed into a 14-gauge reinforced steel enclosure to protect it from outside stresses.

Using standard 3-pin XLRs, the McBoost features three impedance settings to optimize the response, and has a three position high-pass filter switch to reduce low-frequency clutter. Finally, the McBoost will elevate the output to produce added clarity, excitement, and drive for long cables, whether you're in a recording studio, on a live stage, or in a broadcast center.
