Review: it's a solid microphone amp - 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.
Review: Great product - OUTSTANDING customer service! - 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.

## Features

- Adjustable Gain from 19–75dB – this mic preamp provides powerful gain to overcome the limited preamp boost found in many audio interfaces and mixers. It enhances the clarity and fullness of high-impedance dynamic microphones such as SM58, SM7B, MV7 and brings out details. For condenser mics, use in a quiet studio or pair with our RO-05 Noise Eliminator to reduce ambient noise.
- This mic preamp converts mic-level signals to line-level with balanced XLR and 1/4" TRS outputs, ideal for recording through USB audio interfaces and mixers. Not compatible with mobile live-streaming audio interface or speakers without line inputs. Wireless microphones are also unsupported, as their inherent noise would be amplified.
- Turn down the gain on your audio interface or mixer and rely solely on the RO-03 mic preamp. With up to 75dB of gain, it provides more than enough amplification while preventing unwanted noise from double boosting. It can fully replace the gain function of your interface or mixer.
- While the mic preamp delivers up to 75dB of clean gain, you should adjust the level based on your setup, mic distance, and recording environment. The goal is to boost your signal while keeping background noise low. Monitor the input in your DAW or watch the Clip light on your audio interface, and keep the level below -12dB for the best sound quality without distortion or clipping.
- If your recording space isn’t acoustically treated and you’re worried about background noise being amplified, pair the RO-03 mic preamp with our RO-05 Analog Noise Eliminator to achieve a clean, clear sound.

### ⭐⭐⭐⭐ Nice little single channel preamp with a lot of gain, useful for low-output dynamic/ribbon mics
*by E***C on May 27, 2023*

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.
