OFCOSH Microphone Preamp Audio Booster ✔ Active Untra-Clean Gain ✔ Phantom Powered ✔ Plug & Play ✔ Reduce Noise 【DYNAMIC AND POWERFUL】 OFCOSH mic booster can work with almost any dynamic or passive ribbon microphone. 【GIVE DYNAMIC MIC UP TO 25DB】 OFCOSH microphone preamp vastly increases signal strength of dynamic mic, helps dynamic mic to record smooth vocals and acostic instruments. 【NO DAMAGE TO THE MIC FROM 48V】 OFCOSH mic booster protects mics from adverse effects of phantom power. 【PERFECT COMPATIBILITY】 Perfect for podcasts, live streaming, radio broadcasts, live sound, and studio recording. 【How does it work? 】 1. Connect the Mic Booster’s output to a device that can supply +48v phantom power, such as a preamplifier, mixing console, or audio interface. Depending on the equipment used, the Mic Booster can be closer to the mic or the preamp when using long cables. 2. Connect any dynamic, ribbon, or tube microphone to the Mic Booster’s input. The Mic Booster does not pass through the phantom power, making it safe for delicate ribbon microphones. For microphones requiring +48v, like condensers, a separate external phantom power supply is necessary. 3. Begin with the lowest gain setting, then activate the +48v phantom power on your device (preamp, mixer, interface, etc.). Gradually increase the gain to your preferred level. NOTE: ★ Not compatible with condenser microphones. ★ 48V Phantom power needed, not included in the package.
