Cloudlifter CL-1 Mic Activator - Ultra-Clean +25dB Gain

In this review the Cloudlifter CL-1 mic activator proves to be a simple, effective solution for anyone needing clean gain before their preamp. It is designed for home studios and professional recording environments and its single biggest strength is delivering up to +25dB of ultra-clean gain using phantom power while not passing that power to passive microphones. For podcasters, streamers and recording engineers who struggle with low-output dynamics like the SM7B or ribbon mics, the CL-1 is a practical way to increase clarity and reduce noise without changing the microphone's natural tone.

Key Features

• Clean gain: Provides up to +25dB of gain so quiet sources such as vocals and acoustic instruments become usable without adding audible noise.
• Phantom-power driven: Uses phantom power to drive the internal electronics while keeping phantom off the connected passive microphone for safe operation with ribbon types.
• Improved clarity: Raises signal strength to reduce preamp noise and feedback, making dialogue and instruments sound clearer in recordings and live streams.
• Wide compatibility: Works with passive dynamic and ribbon microphones as well as tube, battery, or externally powered mics that do not require passed phantom power.
• Studio-ready build: Metal construction and a straightforward XLR in/out design allow it to integrate seamlessly into home studio, live sound, and broadcast chains.

Who It's For

The Cloudlifter CL-1 is ideal for podcasters, streamers, and project-studio owners who use low-output dynamic microphones and need a clean, immediate gain boost before the preamp. It is particularly valuable for users of mics like the SM7B or for location recordists who want reliable noise-free gain without hauling extra preamps.

Less suitable are setups that already have very high-quality mic pres with plenty of clean gain built in, or users who need on-board EQ, compression or digital conversion features; the CL-1 is a transparent gain device, not a multi-function channel strip.

Pros & Cons

Pros

• Delivers a clean +25dB gain that makes low-output mics usable without adding hiss.
• Does not pass phantom power to the microphone, which protects passive ribbons and avoids powering mics that should not receive it.
• Solid metal construction and simple XLR I/O make it dependable in both studio and live environments.
• Improves clarity and reduces the need for extreme preamp gain, improving overall signal-to-noise ratio.

Cons

• No onboard controls or pads - it is a fixed-gain device, so users wanting adjustable gain must use other gear.
• Requires a preamp and phantom power source to operate, so it is not a standalone mic preamp with monitoring features.

Our Verdict

The Cloudlifter CL-1 is a specialist tool that does one job very well: adding clean, transparent gain to low-output microphones so preamps can operate with less noise. For podcasters, streamers and engineers who need +25dB of reliable boost and broad microphone compatibility, it represents strong value; users who need adjustable processing or integrated features should pair it with other gear.

Frequently Asked Questions

Does it pass phantom power to the microphone?
Answer. No, the CL-1 uses phantom power to run its circuitry but does not pass phantom power on to the connected passive microphone.

How much gain does it provide?
Answer. It provides up to +25dB of ultra-clean gain to raise signal levels before the preamp.

Can I use it with ribbon microphones?
Answer. Yes, it is safe for passive ribbon microphones because it does not transfer phantom power to the mic.
