Review: A simple device that does it's job well! Review: it's a solid microphone amp ## 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 | | Antenna Location | Karaoke, Singing, Streaming | | Audible Noise | 75 Decibels | | Audio Sensitivity | 75 Decibels | | Brand | Rodyweil | | Built-In Media | microphone, warranty card | | Color | Black | | Compatible Devices | Speaker | | Connectivity Technology | XLR | | Connector Type | XLR | | Customer Reviews | 4.2 out of 5 stars 108 Reviews | | Enclosure Material | Metal | | Frequency Range | 20Hz 20kHz | | Frequency Response | 20 KHz | | Impedance | 600 Ohms | | Item Dimensions | 9 x 10 x 11 centimeters | | Item Weight | 400 Grams | | Item height | 11 centimeters | | Manufacturer | Rodyweil | | Microphone Form Factor | Handheld | | Model Number | RO03 | | Number of Channels | 2 | | Polar Pattern | Unidirectional | | Power Source | Corded Electric | | Signal-to-Noise Ratio | 75 dB | | Special Feature | 3.5mm jack, Lightweight, XLR | | UPC | 616859152007 | ## Product Details - **Recommended uses for product:** Karaoke, Singing, Streaming - **Brand:** Rodyweil - **Connectivity technology:** XLR - **Connector type:** XLR - **Special features:** 3.5mm jack, Lightweight, XLR ## Images ![Microphone Preamp Mic Gain Booster with 2 Input Max 75db Gain 48V Phantom Power for Dynamic and Condenser Mic - 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 ### ⭐⭐⭐⭐⭐ A simple device that does it's job well! *by M***E on 3 July 2023* ### ⭐⭐⭐⭐⭐ it's a solid microphone amp *by P***1 on 31 January 2025* ### ⭐⭐⭐⭐⭐ Mic preamp. boost *by N***N on 20 June 2025* ## 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.ae/products/501145926-microphone-preamp-mic-gain-booster-with-2-input-max-75db](https://www.desertcart.ae/products/501145926-microphone-preamp-mic-gain-booster-with-2-input-max-75db) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-04-23*
