- With up to 72dB of clean gain, RO-04 makes even the faintest sounds or distant voices come through full and detailed. Perfect for high-impedance dynamic mics like the Shure SM58, SM7B, or MV7X—unlock their true tone and let them perform at their best, without straining to be heard.
- With an EIN noise floor as low as -120dB, and still -100dB even at max 72dB gain, RO-04 keeps your recordings clean and hiss-free. Even the softest sounds stay clear and full, so your voice and instruments shine without background distractions.
- At just 0.0035% THD at 1kHz, RO-04 captures every nuance exactly as you hear it—no unwanted color or smearing. Perfect for podcasts, voiceovers, and ASMR where accuracy and clarity are everything.
- Unlike cheaper preamps that share one circuit for both mic and instrument, RO-04 uses separate high-impedance and mic input stages—so you can plug in a guitar and a mic at the same time, with independent gain controls for each. Ideal for singer-songwriters and live recording.
- Many preamps get noisy in the last half of the gain knob. RO-04’s unique 11-step gain switch plus trim control keeps noise consistently low across the entire range, giving you smooth, precise adjustments without the hiss jump.
