Review: As my headline suggests, there is not a lot to be said about a device as simple as this. Is your microphone output too low? Simply plug this in, connect your microphone to it and connect this to whatever you are using and "pump up the volume!" :) Also if your mic needs "Phantom power" it can provide it. Nuff said! Review: 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. ## 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B6NG9S4C | | Audio Sensitivity | 75 Decibels | | Best Sellers Rank | #43,122 in Musical Instruments ( See Top 100 in Musical Instruments ) #1,855 in Condenser | | Colour | Black,Transparent | | Compatible Devices | Speaker | | Customer Reviews | 4.2 4.2 out of 5 stars (108) | | Date First Available | 7 September 2022 | | Frequency Response | 20 KHz | | Included Components | microphone, warranty card | | Item Dimensions LxWxH | 9 x 10 x 11 Centimeters | | Item Weight | 400 g | | Item dimensions L x W x H | 9 x 10 x 11 Centimeters | | Item model number | RO03 | | Manufacturer | Rodyweil Audio | | Material | Metal | | Microphone Form Factor | Handheld | | Polar Pattern | Unidirectional | | Power Source | Corded Electric | | Product Dimensions | 9 x 10 x 11 cm; 400 g | | Signal-to-Noise Ratio | 75 dB | | Size | 10 cm x 9 cm x 11 cm | | Special Feature | 3.5mm jack, Lightweight, XLR | | UPC | 616859152007 | ## Product Details - **Brand:** Rodyweil - **Connectivity Technology:** XLR - **Connector Type:** XLR - **Model Name:** RO03 - **Recommended Uses For Product:** Home ## Images ![Mic Preamp for Dynamic and Condenser Microphone Balanced Line Output with Max 75db Gain and 48V Phantom Power - Image 1](https://m.media-amazon.com/images/I/61VuiLiSwDL.jpg) ## Questions & Answers **Q: I’m using a SM58 microphone with a Scarlett 2i2 audio interface. How do I connect and use?** A: Connect SM58 to RO03 XLR input. Link RO03 output to 2i2 6.35mm Line In via XLR-TRS cable or 6.35mm TRS cable. Set 2i2 gain to minimum, then adjust RO03 gain slowly for a healthy signal level. **Q: Can I connect two microphones to the RO03 at the same time?** A: No, you can only use one input at a time. The two input ports cannot work simultaneously. **Q: Can I connect this preamp to an outdoor speaker?** A: Yes. Use a 6.35mm TS cable from the RO03’s TS output to the Mic or Line input on your speaker. **Q: What’s the difference between the 3 output jacks on the RO03?** A: The XLR and TRS outputs are identical, offering more cable options. The TS output is an attenuated signal, ideal for connecting to non-professional devices. **Q: Do I need to turn on 48V phantom power on my audio interface for condenser mics?** A: No. Simply enable the 48V phantom power on the RO03 itself. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by M***E on 3 July 2023* As my headline suggests, there is not a lot to be said about a device as simple as this.

It's really good build. but if you want to connect to the mic out on the back, it's a 6.5mm jack. if you have a 3.5mm jack, use the adapter. Good service. Thanks the delivery, and Rodyweil. ## Frequently Bought Together - Rodyweil Microphone Preamp Mic Gain Booster with 2 Input Max 75db Gain 48V Phantom Power for Dynamic and Condenser Mic - Amazon Basics XLR Male to Female Microphone Cable for Speaker or PA System, All Copper Conductors, 6MM PVC Jacket, 6 Foot, Black - tisino XLR Female to 1/4 Inch (6.35mm) TRS Jack Lead Balanced Signal Interconnect Cable XLR to Quarter inch Patch Cable - 3.3 Feet --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ro/products/522293736-mic-preamp-for-dynamic-and-condenser-microphone-balanced-line-output](https://www.desertcart.ro/products/522293736-mic-preamp-for-dynamic-and-condenser-microphone-balanced-line-output) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-05-15*
