Featuring 48V phantom power and a robust metal build, it’s designed to enhance mic signals for professional-grade recording and streaming, eliminating noise and boosting clarity in any environment. ## Description This microphone preamp can enhance your signal by up to +75 dB with clean and transparent gain. It is compatible with various microphones, including SM7B, SM58, 55SH, and others, whether they are dynamic or condenser microphones. ## 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 | |---------------|-------| | Antenna Location | Home | | Asin | B0B6NG9S4C | | Audible Noise | 75 Decibels | | Audio Sensitivity | 66 Decibels | | Best Sellers Rank | #38,426 in Musical Instruments (See Top 100 in Musical Instruments) #1,481 in Condenser | | Box Contents | microphone, warranty card | | Brand Name | Rodyweil | | Colour | Black,Transparent | | Compatible Devices | Audio Interface, Mixer | | Connectivity Technology | XLR | | Connector Type | XLR | | Country Of Origin | USA | | Customer Reviews | 4.3 4.3 out of 5 stars (120) 4.3 out of 5 stars | | Enclosure Material | Metal | | Frequency Range | 20Hz 20kHz | | Frequency Response | 20 KHz | | Item Dimensions | 9 x 10 x 11 Centimeters | | Item Weight Unit Of Measure | 400 Grams | | Manufacturer | Rodyweil Audio | | Manufacturer Part Number | RO03 | | Microphone Form Factor | Handheld | | Model Name | RO03 | | Model Number | RO03 | | Number Of Channels | 1 | | Polar Pattern | Unidirectional | | Power Source | Corded Electric | | Signal To Noise Ratio | 108 | | 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/71APi25YunL.jpg) ![Mic Preamp for Dynamic and Condenser Microphone Balanced Line Output with Max 75db Gain and 48V Phantom Power - Image 2](https://m.media-amazon.com/images/I/71lFwnvDEWL.jpg) ![Mic Preamp for Dynamic and Condenser Microphone Balanced Line Output with Max 75db Gain and 48V Phantom Power - Image 3](https://m.media-amazon.com/images/I/71KWi4+h9ML.jpg) ![Mic Preamp for Dynamic and Condenser Microphone Balanced Line Output with Max 75db Gain and 48V Phantom Power - Image 4](https://m.media-amazon.com/images/I/51H8QBKH0tL.jpg) ![Mic Preamp for Dynamic and Condenser Microphone Balanced Line Output with Max 75db Gain and 48V Phantom Power - Image 5](https://m.media-amazon.com/images/I/81lpnGUB6wL.jpg) ## Available Options This product comes in different **Model** options. ## 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 ### ⭐⭐⭐⭐⭐ A simple device that does it's job well! *by on Reviewed in the United Kingdom 3 July 2023* 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! ### ⭐⭐⭐⭐⭐ Awesome product!!! *by on Reviewed in Canada 27 February 2025* Fantastic product! Works great and super easy to use. Just a no frills preamp with a nice and low noise floor, my signal always sounds great. I do think it works best with microphones though, for instruments, I like more coloration from less transparent preamps. ### ⭐⭐⭐⭐⭐ Clean sound, reliable. *by on Reviewed in the United States 23 May 2026* The sound on this preamp is incredibly clean. I use it to power a 6-outlet Whirlwind mult-box connection for news conferences, and it gave me the good sound I wanted even with a 100' cable run. Does the job. The cord on the power supply is too short, only about 4'. ## 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.co.il/products/522293736-mic-preamp-for-dynamic-and-condenser-microphone-balanced-line-output](https://www.desertcart.co.il/products/522293736-mic-preamp-for-dynamic-and-condenser-microphone-balanced-line-output) --- *Product available on Desertcart Israel* *Store origin: IL* *Last updated: 2026-06-10*
