Cloudlifter CL-4 Mic Activator

Bring your mics to life and enhance your creative vision. The Cloudlifter CL-4 is here to empower your multi-mic applications to capture every detail with exceptional clarity and strength. Perfect for live sound, house of worship, podcasts, recording studios, theater productions and other applications where activating multiple microphones is desired.


Multi Mic Magic for Your Rack

Unlock the full potential of your microphones—times four. Delivering up to +25dB of clean gain like the original, the CL-4 activates up to four microphones simultaneously. Many of the most incredible-sounding microphones typically require the most gain. Ribbon, dynamic and even tube microphones can be difficult to amplify, even with high-quality preamps. Previously, capturing very quiet sources with these mics has been difficult, without hearing noise and frequency loss caused by the preamp being operated in its upper gain range.

The detail and nuance, the true character of your mic comes to the foreground with the Cloudlifter. This is in remarkable contrast to the tone achieved by pushing the preamp to its upper gain range to produce a similar level of gain.


Not Just Louder, Better

The patented technology dramatically increases microphone output sensitivity without coloring or altering the natural character of the source. Cloudlifters are free of capacitors, resistors, and other distortion-causing components. They utilize a patented Class-A Discrete signal path that directly couples the noise-canceling JFET chips to the microphone and preamp. These innovative JFET chips were initially designed for top-secret military and science applications where quality and clarity are essential to national security, safety and education. With these ultra-high-tech chips used in Cloud products, you can take advantage of these advancements in order to Elevate Your Sound to the highest level while fueling the creative process.


Activated by Cloud… The Industry Standard

The award-winning technology is used by audio professionals worldwide and is the industry standard for low-output mics such as the Shure SM58, EV RE20, and popular ribbon microphones. Additionally, Cloud licensed the patented technology to Shure for use in the innovative active SM7dB microphone, the newest in the legendary SM7 lineage.


A Mod for Your Preamp and Microphone

While most preamps sound great in the middle of their gain range, the last one- third is the most challenging; where signal degradation and noise can occur. Cloudlifters mitigate this by giving you more of the actual microphone itself, upfront and unaltered.

The way the technology works, the Cloudlifter electrically becomes part of your microphone and preamp. By utilizing the preamp's components to complete the circuit, the Cloudlifter’s design offers two distinct noise-canceling gain stages. These occur prior to the signal passing through capacitors and other components that cause distortion and alter the microphone's natural character. The circuit is completed by the components in the preamp and phantom power supply in such a way that they are removed from the signal path. By the time the signal reaches your preamp and passes through capacitors and other electrical components, its negative impact is greatly reduced.

By the time the signal reaches your preamp and eventually goes through capacitors and other types of electrical components that can alter the sound, the negative impact these may have is greatly reduced. This is because more of the signal's authenticity is present up front, meaning the preamp doesn’t have to work as hard to achieve optimal performance. Your microphone becomes active, and your preamp is supercharged to operate within its most comfortable range.


Level Up with More Mic, Less Preamp

All gain is not created equal. The ultra-clean gain of the Cloudlifter coupled to your preamp offers a sound that removes not only the noise, but unwanted coloration and frequency degradation that occurs in proportion to the amount of gain provided at the preamp or interface. Even with a preamp that has a coloration that you like, Cloudlifters open up a different sonic option by having more of the mic’s natural character sitting up front.

Simply put, all Cloudlifters give you more of the actual mic itself while allowing the preamp to operate within its comfort zone. The result is less noise floor, distortion, and alteration to the frequency response. Hearing more of the mic itself and less of the coloration from the preamp is a nice choice to have, creating new options that simply didn’t exist before.


Empower Your Creativity

Bring sonic depth and authentic character to the forefront of your sound. The Cloudlifter brings your sound to life with detail and clarity that is unmatched. This innovative device provides up to +25dB of clean gain, bringing out the subtle details and nuances that could otherwise be lost.

Whether you're recording vocals, instruments, podcasts, or Foley, the CL-4 ensures your microphone captures every detail with exceptional clarity.

About Phantom Power Condensers:
In order to use mics that require +48v phantom power, an additional source of phantom power is required, such as a standalone +48v supply. This is because the Cloudlifter does not pass phantom from the interface to the microphone, this feature makes it safe for all ribbon and tube mics
