Frequently Asked Questions

It won't match the Royer's detail or low-end extension, but the RB 500 delivers a similar warmth at a fraction of the cost—a great starting point.
While other preamps *can* work, the FetAmp is specifically designed to provide the clean, low-noise gain ribbon mics need, and is a good match.
Handle with care, avoid loud bursts of air (like from a snare drum close-up), and use a pop filter—ribbon mics are delicate but surprisingly robust given the material.
