Two Channels of Passive Dynamic and Ribbon Mic Optimization

A must-have tool in the studio and for live sound applications, the Klark Teknik MIC BOOSTER CM-2 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 two-channel MIC BOOSTER CM-2 is extraordinarily simple to use: simply connect an input to a microphone’s output via an XLR cable and connect an output to your preamp, mixing console, or audio interface. The two-channel design allows you to boost two mics at once! Additionally, 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-2 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-2 offers reliable performance, even in the most demanding situations. Its small form factor makes it easy to tuck the MIC BOOSTER CM-2 out of the way, and, by placing it close to the microphones you mitigate the potential from unwanted noise due to long cable runs. The MIC BOOSTER CM-2 is an indispensable workhorse device for recording and live sound engineers.

Klark Teknik MIC BOOSTER CM-2 Dynamic Microphone Booster Features:

  • Provides two-channels of 25dB clean gain for 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 U.K.

Quasi condenser mic machine

Very good product that essentially turns your favorite cartiod mic into a condenser mic. Works very well

Great so far

Over half the cost of the cloud unit. Don't have to turn up the gain nearly as much without it. Using a top of the line Shure SM7B. Sounds great!

Great Value, Well Made, Does the trick!

The Klark Teknik Mic Boost CM-2 did exactly what it said it would do. Boosted my Shure SM57 and an SM58 input signals and really made controlling the gain at my I/O really easy. No longer do I have to get to 7, 8, or 9 on my gain to get good input. Now, I can get a really clean sound at 5 on the gain. That has allowed me to not have to "eat the mic" all the time. I can get a nice sound even when backed off by 6, 8 or even 12 inches away. The unit is a nice small footprint, it's nicely weighted so it stays in place on my desk, and the price is right!

Huge Value for the Money!

This was an experiment of sorts. I bought this booster specifically for a live performance. Being that I was only familiar with mic boosters in studios, pod casting, etc., I was a bit nervous, especially since I had never even heard of the Klark Teknik brand and it was quite a lot cheaper that most other mic boosters - especially a dual channel one. But reviews online seemed positive across the board, and Sweetwater was running a sale on these, so I went for it.

Not sure why I never thought of using these types of boosters for live applications before. It works incredibly well live, and it makes things a LOT easier for the sound engineer. The input signals have so much more gain, so it is easier to get things dialed in without overloading things too much at the sound board.

Background: I do not like using acoustic guitar preamps. To my ears, they all compromise too much, even the most expensive ones. Instead, I prefer to mic acoustic guitars with an instrument mic, as this captures the most realistic and pure acoustic tone possible.

The problem is that for this performance, I was playing with 7 other musicians in the band, and my acoustic guitar was getting lost in the mix.

Used a Shure SM57 to mic the acoustic guitar, which is not a weak mic, but the booster turned the mic into an SM57 on steroids! The acoustic guitar really cut through the mix with the booster way better than before. What an incredible punch. Now I could keep up with the electric guitars and without any feedback.

For vocals I used a Shure Super 55. Same thing, the booster turned this mic into a Super 55 on steroids. Actually, the booster had a more dramatic effect on the Super 55 compared to the S57. The increase in punch, volume and vocal clarity was significant.

Best $ I've ever spent on a single music gear item.

Tks Sweetwater for getting this item to me overseas so quickly!
