Microphone Preamp Mic Gain Booster with 2 Input Max 75db Gain 48V Phantom Power for Dynamic and Condenser Mic

I bought this To amplify my Sennheiser Microphones which I use with Dragon NaturallySpeaking for speech recognition. It is very solidly built and provides clean amplification. I changed out the power supply for third-party power supplies that I use with all of my audio equipment to make sure that there's no noise.The sound is very clear which is necessary for speech recognition. However, it does not provide any additional warmth like the ART preamps that I use for voice recording but it's about one third the price of those units. while the sound is a little dry, it doesn't sound unnatural on my zoom calls.I can't comment on singing are instrumental application since I don't do that.

My initial impression was that the unit was well made. It's heavy, in a sturdy metal enclosure, and the switches and ports seem to be of high quality. I am using it in conjunction with a Fostex cassette 4-track, and I had some technical hook-up questions. My email was answered within a few hours, and the customer service rep was incredibly helpful. We exchanged a few emails until an optimum solution was suggested. The preamp works perfectly, and in fact even makes a very low end mic work/sound great. I am 100% satisfied with my purchase and would happily buy more products from this manufacturer.

I had to dig through a lot of junk in my shed to find my dusty ol' mic. It has a filter to keep popping and other noises you don't really want down to a minimum. I hooked up my amp to this preamplifier and voila! Gain was the first thing I noticed. No feedback, but significantly louder mic output. I love that, I usually have issues with feedback and organizing distances of my equipment to deter that. My voice came through cleaner than I had imagined. This preamp is compact as well, I could fit it in my pocket, but not with jeans on. Overall, this preamp is very nice and beneficial in many applications of use, I highly recommend getting one!

I was interested in trying this because it offers a lot of clean gain (75 dB) for the price, which I thought might be useful for low-output ribbon & dynamic mics. I did a little a/b test comparing the Rodyweil to the built-in preamps of a Yamaha mixer -- the Rodyweil definitely has a LOT more clean gain, which is nice and useful. I tried it with an SM57 and an sE ribbon microphone and it's loud enough for both, without needing something like a cloudlifter. I also tried the line input, and also a condenser mic with the phantom power button engaged, and both worked fine.My only complaints are (like others mentioned) the unbalanced mini jack outputs, which are a pain -- 1/4" would be a lot more useful. Also, when I tried turning the gain knob up and down, most of the action seems to happen towards the very end of the control's travel -- it's fairly quiet quiet quiet and then at the end gets REALLY LOUD, rather than a smooth transition.Also: the little spec sheet that comes in the box describes this as a "2-channel" preamp, which AFAIK usually means a stereo unit, or something with two separate inputs & outputs. This is a mono, single-channel preamp. It does have separate XLR and 1/4" inputs, and you can run a mic and a line signal through both inputs at the same time, but you've got just the one output.For the price, though, I think it's pretty good, and I'm planning on using it on various recording projects.

The phantom power function of this microphone preamp was crucial to powering my condenser microphone, and it worked flawlessly.

Sounded like it was picking up radio waves. Tried new cables, and different plugs, but nothing helped.

Buying this product instead of spending money on a new port or a new microphone is cheaper than the price of a new good port or microphone and it greatly improves your recording.

very nice and useful addition to any studio, this is a great sounding little single channel preamp with phantom power and some respectable specs! very transparent, good interfacing <tho i prefer 1/4" over 1/8" interface plugs>very clear sounding, and enough gain to abuse for nefarious purposes...well built, solid, look forward to really putting it thru its paces.includes decent basic instructions, and a proper power supply. all in all, a worthy piece of kit for a paltry sum!
