After doing a bunch of research about why I was having low input levels with my new Shure SM7B Mic + Focusrite Scarlett Solo Audio Interface I decided to try a pre-amp booster. The stealth seemed like the best bang for the buck and sure enough it worked like a charm. The Stealth went in nicely between the Shure and the Scarlett and blends in perfectly on the boom arm so I don't have an extra box and cable sitting on my desk. I can now turn down the gain on my audio interface and get much more input from the mic than I did previously and with no extra noise. Really great product and less expensive than the Cloudlifter that was recommended to me. Very happy customer here, thanks Coda! ... show more

    • Just what I needed
Recorded using a dynamic mic SM57, helped so much with the excess noise from increasing the gain on my interface. Audio comes out way cleaner

    • Just works
Works as expected. Plug and play. No addition wiring or cords needed. Just plug into the back of your device or where you plug in your mic, and it works.

    • AMAZING LIFE ALTERING PRODUCT!!!
100/10 Didn't save my marriage but at least I'm not sad about it . I have a Black Lion Audio 2x2 interface and a Shure SM58 , even at Max gain I was barely audible without post processing of ~24db. Now I am nice and loud at 50-60% gain!!! Quality seems identical to without if not better than before. Easy install!!! ( literally plug it into the back of your mic. enable 48 volt/phantom on interface.) high quality packaging and quality feel to the plug and a surprising heft to it!!! These are probably insanely cheap to make and the margin of profit must be huge but be for real you aren't making your own, and if you do it won't be this nice. Overpriced for what it is? kiiiinnnda but idk there's far more expensive versions of these that have bad reviews. so imo, GREAT VALUE FOR ITS COMPETITION 100/10 ... show more

    • It requires 48 V phantom power
It boosts the signal perfectly with no discernible distortion or noise (of course you need to provide it with 48 V phantom power which it does not pass on to the microphone! Which is exactly what you want). Great price and an overall great device.

    • Blew Preamps on 2 interfaces
I bought 2 of these abut a year ago. They worked great at first but all of a sudden I noticed the preamp on my Focusrite interface was not working. I chucked it up to the interface being old since I'd had it about 5 years. So I bought a new Mackie interface. Everything was working quite well and I don't use it a lot. But noticed that one day I had to turn up the gain in OBS, which was unusual because with the in line booster I had plenty of volume and never had to add any before. So I didn't think much about it but then about 2 weeks later, tried to use the setup and nothing. Mic preamp is blown on my new Mackie interface. I tried different cable, mics, and both of the Coda Stealth units and got nothing. So be very weary of this product. ... show more

    • Seems really good for the price
This thing actually works pretty well! Seems to be built fine, adds noticeable gain (though less than I was anticipating), and doesn’t seem to add any noise to the signal so the mic still sounds perfectly clean - just louder Compared to the more expensive ones - might as well try this first cause it is a good price. If ya end up needing more oompf then one of the way more expensive options may be needed, but for my use this does the job just fine. Only complaint: connection is a bit loose which feels light it might cause issues in the future if I’m not super careful with it, but doesn’t seem to actually cause any issues with the functionality. ... show more

Tenía el piso de ruido en -50dB y este preamplificador me lo redujo a -60dB, el cambio principalmente se nota en la reducción del siseo, que actualmente es muy mínimo, esos -60dB actuales son principalmente de "Hum" generado por el mismo ambiente del espacio de grabación, el aire y vibraciones bajas del computador, entonces si esa parte acústica y de insonorización estuviera totalmente cubierta, de seguro la reducción del piso de ruido hubiera sido mayor, además parece tener una construcción sólida y hasta ahora todo ha estado bien entonces por eso las 5 estrellas. Aunque su tuviera que mencionar algo que no me gustó, mencionaría que para conectarlo tuve que usar mucha fuerza y de hecho quise intentar quitarlo para hacer una nueva prueba del piso de ruido sin el preamp y más bien desistí, porque temí dañarlo o al micrófono, por la cantidad de fuerza que toca hacer. Fuera de eso, el preamplificador cumple! 👌🏻 ... show more
