The Cloudlifter CL-1 isn’t a microphone or an interface — it’s a tiny inline box that solves exactly one problem: low-output mics being too quiet for cheap-to-midrange preamps. It sits in the XLR chain between the mic and the interface, draws +48V phantom power from the interface just like a condenser mic would, and uses that power to run a Class-A discrete JFET amplifier that adds up to 25 dB of clean gain to the signal before it ever reaches the interface’s own preamp. Critically, it does not pass that phantom power through to the microphone itself — which matters a lot if you’re running a ribbon mic that phantom power could damage, and is simply irrelevant-but-safe if you’re running a dynamic mic like the SM7B.
In practice, this thing exists almost entirely because of mics like the SM7B, the RE20, and other broadcast dynamics that put out a very weak signal. Those mics typically need 60 dB or more of clean gain to hit a usable recording level, and most budget interfaces top out well below that — meaning without help, you’re either cranking the interface gain into audible hiss territory or recording a whisper-quiet track you have to boost (and re-noise) in post. The Cloudlifter’s whole job is to take that burden off the interface preamp: it delivers a chunk of the needed gain cleanly before the signal even gets there, so the interface only has to add a modest amount on top instead of fighting for every last dB.
There’s nothing to configure. No knobs, no switches, no display — just XLR in, XLR out, and a phantom power requirement. You turn on 48V on your interface or mixer, plug the mic into the Cloudlifter and the Cloudlifter into your interface, and that’s it. It’s a “set it and forget it” piece of the chain, which is honestly the appeal — it’s boring in the best way. The tradeoff is that it’s a genuinely single-purpose accessory: if your mic already puts out a healthy signal, or your interface already has a high-gain preamp built in, it does nothing useful for you.
Cloud Microphones, the company behind it, is a small outfit based in Tucson, Arizona, better known in pro-audio circles for hand-built ribbon mics before the Cloudlifter line made them a household name among podcasters. The CL-1 is assembled in the US and typically street-prices in the $99-129 range. That price tag is the thing people push back on before they own one and stop questioning after — it’s a lot of money for a box that does one thing, right up until you A/B a maxed-out cheap preamp against a Cloudlifter-assisted one and hear the difference in noise floor for yourself. And the SM7B isn’t the only reason to own one — any passive dynamic or ribbon mic with a weak signal, like Electro-Voice’s RE20 or a vintage ribbon mic being run into a modern interface, benefits from the same boost, which is part of why it’s stuck around as a general-purpose fix rather than a one-mic novelty.
Pros
- Up to 25 dB of genuinely clean gain, with none of the added hiss you’d get maxing out a cheap preamp instead
- Dead simple — no controls, no setup, just wire it in and enable phantom power
- Does not pass phantom power to the mic, so it’s safe to use ahead of ribbon and other phantom-sensitive mics
- Solid, small, road-durable build with no moving parts to fail
- The go-to, well-documented fix for the SM7B’s low-output problem specifically
Cons
- Single-purpose — does nothing for you if your mic or preamp already has enough gain
- Requires phantom power to function at all, which some very basic mixers/interfaces don’t provide
- Adds another physical link (and cable) to your signal chain, plus another thing to mount or tuck away
- Single-channel only, so a second mic on your setup means a second Cloudlifter
- Costs real money for something that’s just “more gain” — cheaper alternatives exist, with tradeoffs
