Optimizes Passive Dynamic and Ribbon Mics

A must-have tool in the studio and for live sound applications, the Klark Teknik MIC BOOSTER CM-1 coaxes the best performance from your passive dynamic mics by providing an additional 25dB of gain to the signal before it hits a mic preamp. You’ll get more headroom out of your pre for a crisper and cleaner sound. The MIC BOOSTER CM-1 is extraordinarily simple to use. Simply connect its input to your microphone output via an XLR cable and connect its output to your preamp, mixing console, or audio interface. And it runs off of phantom power, so an external power supply isn’t needed, a feature engineers at Sweetwater appreciate. You’ll be shocked by how much better your go-to dynamic mics will sound, and, for ribbon mics, the MIC BOOSTER CM-1 is a total gamechanger!

Rugged, high-performance design

Built to withstand the rigors of live performances and busy professional studios, the Klark Teknik MIC BOOSTER CM-1 offers reliable performance, even in the most demanding situations. Its small form factor makes it easy to tuck the MIC BOOSTER CM-1 out of the way, and by placing it close to the microphone, you mitigate the potential for unwanted noise from long cable runs. The MIC BOOSTER CM-1 is an indispensable workhorse device for recording and live sound engineers.

Klark Teknik MIC BOOSTER CM-1 Dynamic Microphone Booster Features:

  • Provides 25dB of clean gain to passive dynamic and ribbon microphones
  • Powered by 48V phantom power; no power additional power supply required
  • Provides your mic preamp with extended headroom for improved audio quality
  • Robustly built to withstand rigorous live sound applications and high-traffic recording studios
  • Small form factor makes it easy to position close to your microphone
  • Designed and engineered in the UK

Mic booster

It made a great difference to my Mic without adding any noise. So i can have the gain at zero and sound clear and strong. No hiss or hum.

Surprising Value for the Performance

Don't let the price fool you. The Klark Teknik CM-1 is a surprisingly capable tool for the money and compares head to head with the Cloudlifter CL-1. There are a lot of reviews online about the 'perceived' quality of both devices but, unfortunately many of these reviews are entirely subjective. Meaning they only compare 'non-identical' testing methods to archive that perception.
In the video link below, this CM-1 was tested in controlled studio environment with test tones and pink noise and the results were pretty surprising. The CM-1 compared very favorably to the Cloudlifter products and added about .05db of noise and no measurable color to the original audio signal path for its rated 25db of gain achieved.
Solid metal chassis and tank like construction make this no brainer at its price point.

Nice boost

This thing has added a clean, noise-free boost to several of my mics at a very minuscule price point. Definitely pleased with the purchase.
Rated 5/5

I saw some reviews and decided to try but didn't expect the quality.

They say that you get what you pay for. So knowing the quality of much pricier microphone boosters I didn't know what to expect. The reviews I saw were really good and the sound comparisons I listened too were very convincing. So I took a chance and bought one to try out. I put it on a Sennheiser e835 and when I did the first sound check I dialed down my input gain from about 4 o'clock to around 11:30. I was amazed and the sensitivity of the mic was just what I have been trying to achieve without it. I decided to outfit my gig bag with one for every dynamic mic I own.

Needless to say. I'm very happy with these.
