The Cloudlifter CL-1 addresses the pre-amplification challenge for low output dynamic and ribbon mics by giving passive microphone signals a major inline boost, up to +25db, of ultra clean gain while properly loading the microphone's transformer for optimal performance. The Cloudlifter CL-1 is completely 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, making 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.
