The Radial McBoost provides clean gain at the source for low-output dynamic and ribbon microphones, driving long cable runs with ease and allowing you to connect to any preamp as if it were a high-gain ribbon mic pre. Simply connect the McBoost in-line using standard XLR cables and activate 48V phantom to provide power, then select between three impedance settings to optimize the response from the microphone. The McBoost will elevate the output to produce added clarity, excitement and extra drive for long cables whether you are in a recording studio, on a live concert stage, or in a broadcast center.
