The Cloudlifter CL-1 Mic Activator from Cloud Microphones which comes in two pack is a compact, single-input solution for common audio problems in the field and in the studio involving low-output passive microphones, including ribbons. The CL-1 uses any standard phantom-powered mixer or microphone input device to provide up to +25 dB of clean, transparent gain. This improves signal-to-noise ratio and improves the performance of passive microphone signals by driving stronger, cleaner signals over longer XLR cable runs, making them ideal for broadcast, live, and studio applications. The CL-1 is housed in a rugged steel enclosure which offers shielding and durability. Additionally, the CL-1 has provisions for stage or stand mounting.Gives passive mics up to +25 dB additional active output and keeps the direct audio path free-and- clear of transformers, capacitors, and resistors. The CL-1 houses discrete JFET circuitry that delivers clean gain while preserving the natural sonic characteristics of the source.
