Parasound Zphono USB Preamp

The Parasound Zphono·USB is a high-quality MM/MC preamp with an A-D converter and USB output for digital transfer
to a PC or Mac. Its unique USB clipping indicator and gain control assure the highest quality with any recording software.
You can defeat its RIAA EQ if you prefer software-based EQ. Its rumble filter and stereo/mono select will extract the best sound from every LP in your collection. Two line inputs enable easy recording of line level sources, too.
