Must-have Tool for Dynamic and Ribbon Mics

Cloud Microphones' Cloudlifter CL-2 is a two-channel "mic activator" that boosts the clarity and strength of your microphone signal while lowering the noise floor. The Cloudlifter CL-2 is phantom-powered to sidestep many of the common problems that occur with mics and instruments. It delivers up to 25dB of clean gain for XLR mics; up to 12dB for 1/4" instruments and hi-Z sources. In typical Cloud fashion, build quality is outstanding. Incorporating top-shelf parts like a Neutrik combo connector and hi-Z to lo-Z Cinemag instrument transformer, the Cloudlifter CL-2 lives up to Cloud's usual outstanding quality standards.

Noise-free amplification

Many preamps sound great until you push them, when all of the hiss and crackle produced by the amplifier itself end up in the mix. The gain boost provided by your Cloudlifter lets your mic preamp work more efficiently, allowing you to get the levels you need, without the noise.

Totally transparent boost

Cloud Microphones designed their Cloudlifter series around direct-coupled, discrete JFET circuitry, engineered to preserve the natural sound of your mics. So, no matter how dramatic of an impact this transparent technology may have on your tone, you can be sure you're really just hearing your mic at its best.

Instant ribbon preamp mod

Ribbon mics are wonderful, but many microphone preamplifiers are simply too weak to get enough signal out of them. A Cloudlifter Mic Activator will turn your preamp's harmful phantom power into as much as +25dB of extra gain, turning even a budget model into an effective ribbon preamp.

Essential for long cable runs

If you work in a large, multi-room studio or an auditorium like the Sweetwater Performance Theater, you won't believe what a difference a Cloudlifter will make. With its extra gain boost to drive your signal, even cable runs over hundreds of feet won't drain the life out of your sound.

  • Provides up to +25dB of noise-free amplification

All Around Incredible, Very Happy!

First of all, Sweetwater Music's customer service is phenomenal. I recieved my Cloudlifter in four days, free shipping. Made it two days early, before I needed it for a long session. When you purchase a Cloudlifter from Sweetwater, it automatically comes with a two year warranty. Sweetwater will also do in house repairs for you. Although I've haven't had to send anything in, that's a nice feature. The Cloudlifter itself is fantastic, especially when plugging in an SM7B, or something similar. I haven't tested any ribbon mics yet, will probably in the future. Definitely get the two channel if you have a studio and are considering a Cloudlifter or something similar, that way you always have the option of using two mics simultaneously. Overall, I couldn't be more satisfied. Darius at extension 1769, thank you so much for everything, you're the man. I'll definitely be buying all my gear from Sweetwater!

Adds gain, but nothing else.

I run a small broadcasting network, and our studio is a converted spare bedroom. Needless to say, there isn't much space - so the hosts record in cramped quarters. I use the Heil Sound PR-40 mics, which help with sound isolation between hosts, but their output is notoriously low, on par with the SM7B, if not quieter. After plugging in the CloudLifter, our mics came alive! For the first time, I was hearing the mic itself and not my low-quality preamp. This thing adds gain, but nothing else. It's my best upgrade to the studio so far. The Machine couldn't run without a CloudLifter in our signal chain.

Perfect Complement to Cheap Mic Pres

If you have a mic pre with a relatively low input impedance and not a lot of gain, this box is killer for low output mics such as ribbons. Not only do you get 18+ dB of clean gain before your preamp, but this box provides an ideal load for velocity sensitive mics. With a 3 kOhm input impedance, the loading is just right to give a ribbon or a moving coil dynamic mic a fuller frequency response and a smoother top end.

Works Wonderfully, great for SM7B and SM58

I have a small Mackie FXPro 8v2 Mixer. It works very well (recognized in Audacity under Linux right away). But it has limited gain, and with dynamic microphones like the Shure SM58 or the SM7B you have to basically max the gain and even then it's not so great. Buy an extra pair of short XLR cables and put this inline with your mics and boom, instant very clean gain. Really works well.

I put up a Bleumlein pair of MXL 144 ribbon mics that I had changed the transformers and re-tensioned the ribbons to match each other (one ribbon was much too slack when it arrived after shipping, good thing I checked!) I used Lundahl 2912 transformers in them and then put them through the two channel cloudlifter you sold me. Ed, I kid you not, the effect was nothing short of recorded reality. I would recommend that everyone have a recording of a loved one's voice with this setup in case they ever lose that person and want to remember every nuance of that person's voice with no trace of recording artifacts or coloration. Natural, relaxed, and real. Recorded reality. I had to turn the gain down on this microphone setup to lower levels than any of my other condenser or tube microphones. Not a TRACE of hiss or distortion. People thing that a ribbon will always do that high end roll off. NOT SO! I love my high end, I am a flutist and a piccolo player. I love my high end and I know what high end really, really sounds like. This Cloudlifter/ribbon setup goes beyond the audible range of hearing. (probably quite a bit beyond) In comparison with my condenser mics, I can't hear any roll off and neither can the younger ears around here.
