## Overview

The 2026 Upgraded RO03 Mic Preamp delivers professional-grade ultra-low noise performance with a -120dB EIN, a practical 19~66dB gain range, and a high-impedance 1MΩ instrument input. Featuring versatile XLR, TRS, and TS outputs and powered by a convenient Type-C supply, it’s engineered for flawless studio-quality recordings and seamless live streaming on the go.

## Description

The 2026 latest version focuses on noise reduction, improving the EIN to -120dB, achieving professional-grade noise performance. 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.

Review: A simple device that does it's job well! - 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: Clean sound, reliable. - 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'.

## Features

- The 2026 latest version focuses on noise reduction, improving the EIN to -120dB, achieving professional-grade noise performance. 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 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.
- This RO03 mic preamp is equipped with three types of output ports. Balanced XLR and TRS outputs connect seamlessly to USB audio interfaces, mixers, compressors, EQ units and other professional studio gear. The unbalanced TS output works perfectly for phone live streaming mixers, KTV systems, active speakers and other consumer audio devices, covering both studio recording and live broadcast scenarios.

## 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.
