Radial McBoost Mic signal booster, class-A fet with 25dB gain, load adjust and filter
Microphone Signal Intensifier
The Radial McBoost is a microphone signal booster that is professionally designed for elevating the output of a dynamic or ribbon microphone for greater clarity and transparency, and for providing enough clean gain for connecting to any preamp.
Boost your signal at the source
The Radial McBoost is capable of providing a clean gain at the source for low-output dynamic and ribbon microphones, to drive long cable runs with ease and to allow the user to connect to any preamp as if it were a high-gain ribbon mic pre. Simply connect the Radial McBoost in-line with the use of the standard XLR cables and activate 48V phantom for providing the power, then select between three impedance settings for optimizing the response from the microphone. The Radial McBoost will elevate the output for producing added clarity, excitement and extra drive for long cables whether the user are in a live concert stage, in a broadcast center, or in recording studio.
Features
- 26dB signal booster for dynamic & ribbon microphones
- Class-A dual transistor circuit for transparent operation
- Powered by 48V phantom power
- Three-position impedance selector & variable gain
