When connecting the preamp to an audio interface with the proper cable (such as a 1/4 inch TRS cable), it delivers an extremely clear signal, allowing you to obtain professional recording results on a low budget. - The previous version boasted a maximum gain of 75dB, which was unattainable in actual use. Moreover, severe background noise would occur when the knob was turned to around 70dB, causing great inconvenience to many users.This update sets the gain range at 19~66dB, a value that is fully achievable in real-world use. Even at maximum gain, no obvious noise is produced, making it highly practical. - The TS instrument input in the old version featured low impedance, resulting in signal distortion and frequency loss due to impedance mismatch when used as a DI box for instruments.This time we have increased the instrument input impedance to 1MΩ, greatly improving performance for musical instruments. Note: The two input ports cannot work simultaneously. - With the rise of individual streamers, more recording scenarios have moved from traditional studios to outdoor environments. Therefore, we switched the power supply to Type-C for enhanced portability.We also replaced the old power supply scheme with a new one that offers wider compatibility, suits more power supply conditions, and reduces the chance of current noise for individual users. - We have continuously collected user feedback, conducted in-depth research and analysis on noise issues, and applied these improvements to the product.We have also found that some noise issues are caused by improper connections. Our tests show that connecting the preamp to the XLR input of an audio interface produces higher noise than connecting to the TRS input.Therefore, we strongly recommend users connect the preamp to the TRS Line input of the audio interface with suitable cables for the lowest noise. - We will continue to collect user feedback and develop better versions. If you have any ideas, feel free to contact us.Even the best designs require manual assembly, which may occasionally lead to oversights. For this reason, we provide 2-year after-sales support for this preamp. Any quality issues can be resolved with free return or replacement. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B6NG9S4C | | Antenna Location | Instrument Recording, Vocal Recording | | Audible Noise | 75 Decibels | | Audio Sensitivity | 66 Decibels | | Best Sellers Rank | #6,182 in Musical Instruments ( See Top 100 in Musical Instruments ) #6 in Microphone Preamps | | Brand | Rodyweil | | Built-In Media | 1 * Power Adapter, 1 * Power Cord, 1 * RO03 Mic Preamp, 1 * User Manual | | Color | Black | | Compatible Devices | Amplifier, Audio Interface, Audio Mixer, PA System, Speaker | | Connectivity Technology | Type C, XLR/TRS/TS | | Connector Type | USB Type-C, XLR/TRS/TS | | Customer Reviews | 4.3 4.3 out of 5 stars (137) | | Frequency Response | 20 KHz | | Impedance | 1000000 Ohms | | Item Dimensions | 3.54 x 3.94 x 4.33 inches | | Item Weight | 400 Grams | | Manufacturer | Rodyweil Audio | | Mfr 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 | EIN -120dbV, Gain: 19~66db, Max Output: +26dbU, Power: 5V 1A (Type C), THD+N: 0.0035% | | UPC | 616859152007 | ## Product Details - **Brand:** Rodyweil - **Color:** Black - **Compatible Devices:** Amplifier, Audio Interface, Audio Mixer, PA System, Speaker - **Connectivity Technology:** Type C, XLR/TRS/TS - **Connector Type:** USB Type-C, XLR/TRS/TS - **Included Components:** 1 * Power Adapter, 1 * Power Cord, 1 * RO03 Mic Preamp, 1 * User Manual - **Model Name:** RO03 - **Polar Pattern:** Unidirectional - **Recommended Uses For Product:** Instrument Recording, Vocal Recording - **Special Feature:** EIN -120dbV, Gain: 19~66db, Max Output: +26dbU, Power: 5V 1A (Type C), THD+N: 0.0035% ## Images ![2026 Upgraded RO03 Mic Preamp, 120db EIN Ultral Low Noise Booster, for Dynamic & Condenser & Ribbon Microphone & Instrument, XLR/TRS Line Out, Type C Powered,with Build in 48V - Image 1](https://m.media-amazon.com/images/I/71APi25YunL.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. ## 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? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/470901199-2026-upgraded-ro03-mic-preamp-120db-ein-ultral-low-noise](https://www.desertcart.sn/products/470901199-2026-upgraded-ro03-mic-preamp-120db-ein-ultral-low-noise) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-06-24*
