Radial McBoost Microphone Signal Booster

The Radial McBoost is a high-performance microphone signal booster designed to raise the output of a typical dynamic microphone for better transient response, and boost the signal of a low-output ribbon mic to a level usable for mixing consoles or preamps that may not provide sufficient gain.

The 100% discrete Class A circuit design starts with a dual-transistor J-FET circuit to produce up to 25dB of gain without introducing noise, color or artifact. Each individual transistor is carefully measured and sorted by batch to meet design specifications for certified performance. As with all Radial products, the circuit board is then loaded into a reinforced 14-gauge steel I-beam housing to avoid external stresses due to torsion, which could otherwise lead to premature part failure. A book-shaped cover creates protective zones at each end to shield switches, potentiometer and connectors from the rigors of the road.

Simply connect the McBoost in-line using standard 3-pin XLR connectors and activate 48 V phantom power, then choose from three impedance settings to optimize microphone response. The McBoost will elevate the output to produce more clarity, excitement and dynamism for long cables, whether you’re in a recording studio, on a concert stage or in a broadcast center.
