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'.
Review: it's a solid microphone amp - I bought this To amplify my Sennheiser Microphones which I use with Dragon NaturallySpeaking for speech recognition. It is very solidly built and provides clean amplification. I changed out the power supply for third-party power supplies that I use with all of my audio equipment to make sure that there's no noise. The sound is very clear which is necessary for speech recognition. However, it does not provide any additional warmth like the ART preamps that I use for voice recording but it's about one third the price of those units. while the sound is a little dry, it doesn't sound unnatural on my zoom calls. I can't comment on singing are instrumental application since I don't do that.

## 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.

## 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.

### ⭐⭐⭐⭐⭐ Great product - OUTSTANDING customer service!
*by R***. on December 21, 2024*

My initial impression was that the unit was well made. It's heavy, in a sturdy metal enclosure, and the switches and ports seem to be of high quality. I am using it in conjunction with a Fostex cassette 4-track, and I had some technical hook-up questions. My email was answered within a few hours, and the customer service rep was incredibly helpful. We exchanged a few emails until an optimum solution was suggested. The preamp works perfectly, and in fact even makes a very low end mic work/sound great. I am 100% satisfied with my purchase and would happily buy more products from this manufacturer.
