Class-A Signal Booster

The 100% discrete design of the McBoost makes it one of the best in its class, featuring a class-A circuit for optimal audio quality and minimal distortion. The McBoost was designed to elivate the signal level of a low output microphone so it performs better within a mixing console. All you have to do is connect the McBoost between the mic and preamp and you're good to go. The McBoost is also highy durable thanks to Radial's trademark all-steel construction, featuring book ends that protect the switches and controls.

Premium-Quality Components

As well as the class-A circuitry, the McBoost also features a slew of components and design aspects that result in a high-performance signal boosting unit. The internal section of the unit features hand matched transistors for exceptional performance from the dual FET class-a circuit. This produces up to 25dB of boost which can be changed via the front-panel level control. There is also a 3-position high-pass filter that eliminates excessive rumble and proximity build-ups. Additionally the McBoost features a impedance selector that has 3 settings to provide optimal lod on the microphone for increased accuracy.
