Cloud Microphones Cloudlifter CL-1 +25 dB Mic Activator

SKU CH-37W3-6JMW8

Provides up to 25 dB of clean gain for passive dynamic and ribbon microphones using phantom power without passing it to the mic

  • Provides up to +25 dB clean gain for passive mics
  • Improves signal-to-noise ratio on low-output microphones
  • Drives stronger signals over long XLR cable runs
  • Rugged steel enclosure shields and protects circuitry
  • Mounts on stage or stand for flexible placement

Purpose & Audience

The Cloudlifter CL-1 is a single-input mic activator that adds up to +25 dB of clean gain to passive dynamic or ribbon microphones using standard phantom power. It is built for broadcast, live and studio engineers who need stronger signals over long XLR runs without adding noise or colouration.

Installation & Common Issues

The unit is self-contained and requires only a phantom-powered mixer or interface to operate; simply place it between the microphone and the cable. It does not pass phantom power to the mic, so ribbon models stay safe, but it also means the activator cannot supply power to condenser microphones that need it.

Interface Limits

The device relies entirely on the phantom power available from the connected preamp or mixer, so available headroom and current draw are limited by that source. It provides a fixed +25 dB boost with no variable control, and it handles only one microphone channel per unit.

Questions about this item

How can I confirm the Cloudlifter CL-1 is providing the full +25 dB gain after connecting it between my dynamic mic and the mixer?

Enable phantom power on the mixer input; the CL-1 draws that power to activate its internal circuitry. You should hear a noticeably stronger, cleaner signal from the microphone without adding noise, confirming the gain stage is working.

What comes in the box with the Cloudlifter CL-1 and what extra items are required to operate it?

The package contains the single-channel CL-1 unit in a rugged steel enclosure with mounting provisions. You must supply a standard XLR cable to connect the microphone to the CL-1 and a second XLR cable from the CL-1 to a phantom-powered mixer or interface.

Should I choose the single-input CL-1 or a multi-channel version for my setup?

The CL-1 provides one input and up to +25 dB of clean gain for a single passive dynamic or ribbon microphone. If you need to boost two or more mics simultaneously, select a multi-channel Cloudlifter model instead.
