Purchased last year at Music Land Key Shinsaibashi. It didn't suit my setup, so I only used it for testing and hardly ever used it. I kept it carefully, thinking I might use it someday, but it seems I won't need it, so I'm selling it. Production has ended, and I don't think it's available anymore. It's the E version. Comes with a dedicated insert cable. RNP8380(EE) RNC1773(E) FMR AUDIO's "Really Nice Tracking Combo" is an advantageous combo pack that includes two units: the 2-channel microphone preamp "RNP8380" and the stereo compressor "RNC1773," plus two specially made insert cables for smart connection between the two units.
