Klark Teknik MIC BOOSTER CT 1 Compact Dynamic Microphone Booster with Preamp

Works AMAZING! For the cost, you really can’t beat it. I use it with an Elgato Wave DX to get a little extra headroom. Would buy again in a heartbeat. Sounds great, great value!

I have been using the CT 1 for two months in my home studio with excellent results. My signal chain is: SM57 > Mic Booster CT 1 > no-name XLR > MBox 2 Mini > USB port on laptop PC > Audacity. My measurement tools are just my own ears. In practical terms, the input signal is noticeably higher, and I do not detect any changes in tone coloration nor added noise. My application is voice work for corporate training content and podcasting. The attached image my shows results using the above signal chain, 48v phantom power, input gain set to 3:00, and speaking [silence] "the red fox jumped over the lazy dog" [silence]. Track 1 is the SM57 only. Track 2 is the SM57 + CT 1. Let your eyes be the judge! The build quality is good enough for my home studio use. Fitment is comfortably tight/secure. This simple device has elevated the quality of my recordings using my existing gear with no learning curve.

This mic booster works excellent, even with a not expensive mixer, the gain is amplify without any problem, and the sound quality still excellent, obviously using the parameters for a different voice frecuency.

I bought this unit due to the compact size thinking it may be a nice portable solution for field recording with some dynamic microphones that require higher gain. It was so cheap it was almost an afterthought. It took several weeks for me to receive it amid the current CCP viral pandemic. It appears well made out of aluminum and seems like a higher quality mass produced product. It is heavy, had nice packaging, solid appearing connectors that fit my Mogami cables (clicked in securely), and a clean smooth finish! A cheap looking serial number sticker is affixed to the unit - it was applied crooked and really detracts from an otherwise very nice looking product. This should have been laser etched in my opinion. As to performance, I tried it on a couple of microphones and compared it to my other microphone pre-preamplifiers (Cloudlifter CL-1 & Cathedral Pipes Durham). I found the noise levels all very low but both the CL-1 and Durham required less preamp gain compared to the Klark Teknik unit in order to reach similar loudness levels. I was a little surprised as it was noticeable. I am unsure if this is unique to my unit or the couple of microphones tested so I plan to spend some additional time using the unit and update the review if I find variation with other microphones.

The amplifier allows me to lower my recorders input, thus reducing the noise floor. The unit is solid. Things to consider: Where do you put it. When attached to the microphone it adds weight, length and a moment arm to the connection. I would recommend leaving it on the stand when used on the microphone. The form factor of the pre-amp prevents it being plugged directly into most mixers or recorders. Perhaps a short patch cable from the mixer would be the way to go if you wish the microphone to be mobile. Performance is satisfactory. I use it with a Tascam DR40's phantom power.

I am a quieter singer for the most part. I like to make alt pop with a sort of hushed vocal, though I do branch out a bit into a louder vocal. But I really needed a boost in volume going into my DAW so I could work immediately with the audio without having to normalize each take or use a similar approach. This really did work even better than I hoped. Somebody complained that it was heavy and fell off their mic. I had the same experience until I realized you sort of have to slightly wiggle it and get it to click onto the mic. Since then, I've had no trouble. At first, it can seem like it's on, but it needs just a little bit more of a push to snap on to your XLR connector. Just make sure you activate your phantom power on your audio interface, or else you won't notice any difference. The boost on this is just amazing for the price. I had considered another much more expensive option, but I have a tight budget as this is my hobby. Honestly, I highly recommend this thing and I probably should buy another one just to have on hand.

I hope it's not too soon to celebrate, but so far I LOVE this thing! It boosts the mic volume quite a lot on my Zoom R24 recorder so that the volume hiss is gone. I was able to get the vocals (in my demos) nice and loud without a lot of noise floor. So far, I'm very happy with this product. Also, I didn't need any phantom power to use it. (Edit: I actually do need phantom power if I am not running my mic through my effects pedal. It doesn't seem to work as well without the pedal, even with phantom power turned on, but maybe my recorder is just not performing as it should anyway. When paired with the pedal, the adapter is totally wonderful.) This little thing is very powerful, so you really have to make sure to turn the volume down low enough so that it doesn't clip. It's great that one doesn't need to turn it up as high because that means much less hiss and noise in the final recording! Everyone has a different set up, so your mileage may vary. (Remember that this is for dynamic mics, and other passive mics, not condenser mics.)

This thing was on back order when I purchased it, the price was outstanding and product had great reviews so I waited. I've gotten a new audio interface and cables thinking they were the issue, until finally I replaced my smb7 mic thinking well I guess it's the mic... while all along it was this piece of garbage. I wanted to love this thing! I honestly think it even messed one of my mics up... I dont know if it's possible but before I got this thing my AKG had a different sound to it, it now has an awful sound to it and is unusable. I ended up wasting so much more money trying to use this booster. My advice.. buy more expensive one.

I'm new to owning a dynamic mic and the one I have the ATR 2100x was way too quiet, maxing out the gain on my Scarlett raised the noise floor and made the recordings unusable. My mate came over with a Cloudlifter to troubleshoot the mic and turns out I needed a booster. I decided to give this one a try and it worked just as well, the build quality is solid and it's heavy for its size. I strongly recommend giving the Klark Teknik CT1 a try if you're picking up a dynamic mic.

The Klark Teknik MIC Booster CT 1 has been a fantastic addition to my audio setup. What I immediately found was how well it boosted the signal from my dynamic microphone. It worked so effectively that I actually had to turn the gain down on my audio interface, which was a pleasant surprise and quite a contrast to how I typically had to run things before. While the price is on the higher side for such a compact unit, the performance really justifies it. Beyond just the strong, clean signal, I also noticed a significant improvement in managing feedback. The clearer, hotter signal from the mic, thanks to the CT 1, really helped to reduce feedback issues I'd been experiencing. It's truly a simple, effective tool that's made a noticeable positive difference in my sound quality and overall control.

Excelente reemplazo para Cloudlifter, FetHead, Dynamite o similares, a una fracción del costo. El empaque es sencillo y elegante, súper bien protegido el producto. El preamp es compacto y muy pesado para su tamaño, se siente de excelente calidad y funciona perfecto. En mi caso lo conecté directo a un Shure SM7B y de ahí a la interfaz, yo uso una GO XLR de TH Helicon. Antes de adquirir este producto tenía la ganancia en 55dB lo que producía un ligero ruido perceptible al estar todo en silencio, ahora baje la ganancia a 30dB y me escucho un poco mejor que antes pero el ruido desapareció... el sonido es mucho más claro. Su costo real es de $30 dólares (comparado con $100-$150 por opciones conocidas) por lo que está a un súper precio en Amazon por menos de $700 pesos pero probablemente subirá o se agotará.

Antes de comprar mi Shure Sm7b y mi Rode procaster sabía que necesitaría un preamplificador, ya que son micrófonos que requieren mucha ganancia. Mi interfaz es la Yamaha Ag06. Busqué información sobre cuántos dbs brinda a los micrófonos dinámicos y no encontré nada. De todos modos compré el Sm7b y el Procaster y pues mi interfaz no daba el ancho en cuanto al volumen. De antemano también sabía el elevado precio del cloudlifter y el fethead y que no podía darme el lujo de comprarme uno. Después de mucho investigar me encontré con el Mic booster ct1 de Klark Teknik. Chequé las buenas reseñas...y son ciertas. Bueno, bonito y barato. Me costó menos de 700 pesos mexicanos, unos 34 dólares. Brinda los dbs necesarios para que mis grabaciones salgan limpias, sin ruido. El envío super rápido, varios días antes de la fecha indicada. Cuando salga a la venta cómprenlo porque se agota de inmediato.

Used it once Live to power an RE20. Sound tech was happy I had it. We'll see how it holds up over time but it seems like a solid little device.
