Powered via USB (bus power) or optional 5 V DC external adapter — useful if phantom power + demanding inputs cause USB power constraints. &nbsp;</p><p> Compatibility</p><p> Works plug‑and‑play on Windows and macOS; many DAWs accept it natively. Loopback + RCA inputs also can make it work with mixers, keyboards, media players, etc. &nbsp;</p><p> </p>
