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.\u003c\/li\u003e\n\u003cli\u003eThe 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.\u003c\/li\u003e\n\u003cli\u003eThe 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.\u003c\/li\u003e\n\u003cli\u003eWith 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.\u003c\/li\u003e\n\u003cli\u003eWe 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.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOverview\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Uses For Product:\u003c\/strong\u003e Instrument Recording, Vocal Recording\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Rodyweil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel Name:\u003c\/strong\u003e RO03\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnectivity Technology:\u003c\/strong\u003e XLR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Type:\u003c\/strong\u003e USB Type-C, XLR\/TRS\/TS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecial Feature:\u003c\/strong\u003e 3 output simultaneous usable, EIN‑120dBV, extremely low noise‑floor, Variable gain: 19~66db, with +4dbU \u0026amp; -10dbV output\n3 output simultaneous usable, EIN‑120dBV, extremely low noise‑floor, Variable gain: 19~66db, with +4dbU \u0026amp; -10dbV output\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Devices:\u003c\/strong\u003e Amplifier, Audio Interface, Audio Mixer, PA System, Speaker\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e 1 * Power Adapter, 1 * Power Cord, 1 * RO03 Mic Preamp, 1 * User Manual\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePolar Pattern:\u003c\/strong\u003e Unidirectional\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Rodyweil","offers":[{"title":"Default Title","offer_id":48388709253341,"sku":"B0B6NG9S4C","price":82.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0834\/3381\/6285\/files\/41pOJmkhPFL.jpg?v=1787012983","url":"https:\/\/listenora.us\/products\/ro03-mic-preamp-2026-upgraded-66db-gain-120db-ein-ultra-low-noise-for-dynamic-condenser-ribbon-microphone-instrument-with-xlr-trs-ts-line-out-type-c-power-input","provider":"Listenora","version":"1.0","type":"link"}
