True to its name, Radial's McBoost boosts the output of dynamic mics, giving you better transient response. You can also use it on your low-output ribbon mics to bring them up to optimal input level for your console or preamp. McBoost's 100% discrete Class A circuitry starts with a 2-transistor J-FET circuit that produces up to 25dB of clean gain. Connect McBoost in-line and activate phantom power. Choose one of three impedance settings. Kick in the 3-position level switch if needed. You're ready to rock. McBoost's elevated output adds clarity and the drive you need for long cable runs in the studio, broadcast center, and onstage.
