## Overview

The Rodyweil RO03 Microphone Preamp delivers up to 75dB of clean, adjustable gain with 48V phantom power, perfect for dynamic, condenser, and ribbon mics. Featuring balanced XLR and 1/4" TRS outputs, it enhances mic signals for professional recording setups, reducing noise and distortion while replacing your interface’s gain stage for superior audio clarity.

## Description

Application: Dynamic Mic, Condenser Mic, Ribbon Mic.

## 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.

## 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.
