Cloudlifter CL-1 Mic Activator. "The Cloud Microphones Cloudlifter CL-1 Mic Activator offers up to +25db of ultra-clean gain, for passive microphones, inline using phantom power. There are certain mics revered for their sound quality. Among them are passive ribbon mics, such as the Royer R121 (#581141 or MXL R40 (#H69305), and low-sensitibity dynamic mics, such as the Shure SM7B (#270247) and the Electro-Voice RE20 (#270009). But if your preamp doesn't have enough gain or the right impedance requirements, these mics won't perform well. So what do you do if you can't afford a high-end preamp with tons of gain? The Cloud Microphones Cloudlifter CL-1 Mic Activator is the solution. The Cloudlifters address problems due to gain and impedance requirments by giving passive microphone signals a major inline boost, up to +25db of ultra-clean gain, while properly loading the microphones' transformer for transparent operation. The Cloudlifter CL-1 is self contained, driven only by the phantom power from your mixer or preamp. Ideal for dynamics and ribbons alike, the CL-1 turns phantom power into the extra gain required for using passive microphones. The immediate dose of extra gain can make even a budget microphone/preamp combination sound clean and professional. For broadcasting and live sound, the active output signal of the CL-1 can prevent added noise over long cable runs. With endless uses, Cloudlifters are quickly becoming a standard addition to professional, project and home studios. Read what the pros are saying about the Cloudlifter: ""It's simply about gain - the Cloudlifter is a clever and useful solution..."" - Rob Tavaglione, Pro Audio Review February 2010 ""The Cloudlifter is a winner. It solves problems some ribbon-mic owners don't even know they have. It does exactly what it claims to do, and does so well."" - Matthew Mcglynn, Recording Hacks February 2010 "
