The Cloudlifter CL-1 Mic Activator from Cloud Microphones is a compact, single-input solution for common audio problems in the field and in the studio involving low-output passive microphones, including ribbon mics.


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.

Transparent Gain

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

The Applications

Use with noisy or low-gain preamps

Use with mixers/preamps that negatively impact the sound at higher gain settings

Use with low-output dynamic microphones and ribbons

Mic softer sound sources such as acoustic instruments and voice

Use for long cable runs


The Features

Gives passive mics up to +25 dB additional active output

Provides 2 distinct stages of clean gain

Easy to use self-contained design requires only phantom power

Recommended for use with all passive dynamic microphones

​​​​​​​- Compatible with tube, battery, or power-supply-driven microphones

Safe for all passive ribbons with no transfer of phantom

Utilizes Patent Pending Class A, Discrete JFET circuitry

Ideal impedance loading for optimal performance at 3 kilohms

Rugged, road ready, and portable, for studio, stage, and broadcasting
