in-line microphone preamp for Dynamic and Passive Ribbon Microphones (UPGRADE BRASS)

I thought there would be a significant difference from the cloudlifter... But no! Nothing bad to say, and I would recommend this over the overpriced cloudlifter everyday.

Works great with a condenser mic but doesn't work well with Sure mics as it generates a higher gain creating background noise if you're using this for a podcast.

Great little device. Easily a clean +12dB of input gain with no noise introduced. I keep it with my TB mic and may pick up a few more for off-stage announcement and talkback mics!

I got the db boost that they advertised, and it is a well made product. I have getting some high end issues with S's, I am using a Shure SM7B so I think that may have been the issue and not preamp. I only needed it for that mic, so I just eq the problem out of the vocals. It is only an issue with singers, not for an acoustic guitar for example.

my dynamic mic wasn't loud enough and required a preamp. Louder this to give me a little boost. It works just fine

The unit did boost the signal, but came with a very noticeable electrical hum making the product virtually useless while using a sm7b mic and 3rd Gen Scarlett 2i2. Checked all cables and they were fine. Ended up buying a used cloudlifter which has performed perfectly. You get what you pay for unfortunately. I returned the product without troubles which I do have to give credit for. I don't recommend this product.

gives my røde procasters gain stage that boost to bring it to mic level to be heard.participants in conference meetings always tell me that i sound as if i were in a professional radio station booth, and im convinced i'm getting enough clean gain to the mic to provide that warmth to the sound of my voice.much less expensive than the competition and the gain is still 100% pristine. what's good is that it doesn't pass thru phantom power from your interface to the dynamic mic, so you can rest easy that you won't cause undue interference to your microphone.be wary, the way these devices work is that they need phantom power from your interface, and they plug into dynamic mics which don't play nice w phantom power, so that's what i mean when i say they don't pass thru; they take the interface which applies the phantom power, but then is given to the manayo (mic activator/preamp) which passes thru gain without sending phantom power to the mic itself.there are a lot of butting heads about if phantom power damages dynamic mics, but i just act like they do, so im not going to test it.

Honestly, I did not expect this to perform as well as it does. I got it to use with a Zoom H6, which has pretty noisy preamps (EIN of -120dBu), but it even improves upon my Presonus Studio 26c interface (good preamps, but not the best by today's standards (EIN -125dBu)). The product doesn't feel flimsy, but it doesn't feel particularly sturdy, either. But at $30 (compared to $80 or more for the name brands), I can live with that.However, you should only get this if your audio device has an EIN rating higher than -128dBu (-120dBu, for instance; most modern preamps are REALLY good, though) or it doesn't have enough amplification for your dynamic mic of choice (keep in mind this won't work with a condenser).Definitely worth the price for the performance.
