OFCOSHMicrophone Preamp Audio Booster, Professional Mic Booster Activator Preamplifier Compatible with Dynamic and Passive Ribbon Microphones

I used to have my soundcard gain on level 60 to have a good mic gain but with this little gadget, I o ly have my gain on level 25 and my mic picsy voice like a condenser mic..without picking any external sounds from within.

I acquired this for a wireless microphone system that had a relatively weak signal through the XLR jacks. They are straightforward to use, and the phantom power from the mixer simplifies the setup process.

I've been using the OFCOSH mic preamp for around a month now. I've used it at band practice in a high volume environment with minimal results. And while I could tell that it did in fact boost the signal, it wasn't enough to make a huge difference in over all quality.Where the booster really worked well, in my opinion was in a podcast scenario. I could tell a noticeable difference in the sound quality when it was used with only the spoken word. There was an added volume as well as clarity boost. I was still able to maintain the mid level warmth, whereas some boosters have been known to give a tinny sound to the mix, the OFCOSH did not. So while results may vary depending on use, I am very pleased with the quality and would recommend for use for podcast or a light rock or acoustic music project. Thank you.

I tried it with a couple of Rode PodMics. It did boost the signal, however it also cut out some of the low mid-range frequencies. It was more noticeable on male voices. I ended up sending it back.

This has one simple job -- it boosts the level of the audio signal from a dynamic or ribbon mic that has relatively low output. So it is especially appropriate for a mic like the Shure SM7b, which is notorious for having rather low signal output by itself.Two important things to nnote, though, which I didn't fully understand before I ordered it:You do need to use it on an input that provides phantom power, but it does not send that phantom power to the microphone itself. It uses the phantom power for *itself* to work, but it does not pass it on to the microphone. What that means is a) it will not work with a condenser mic that needs phantom power (unless you use an additional, separate phantom power source between this preamp and the mic, and b) it is safe to use with a ribbon mic that would otherwise be damaged if you sent it phantom power.The signal is clean and it does not appear to add a lot of noise to the signal.It is extremely solid, metal construction, and it is very small for what it does (only about the size of a male to male XLR adapter)
