Digital Phono USB Preamplifier

Offering superb and measured sonic performance, NAD combines two simple solutions – Digital Phono and the USB Preamplifier – into one small device

Making it easy to add phono to stereo amplifiers and AV receivers without a phono input.

The PP 4 uses a shielded USB cable and recording level control, which reduces noise and improves the analogue-to-digital conversion process.

• Digitise your treasured vinyl collections to a PC or Mac
• Both MM (moving magnet) and MC (moving coil)
• Line input to allow for the transfer of cassette tapes
• VinylStudio Lite Software for ripping LPs and burning audio CD
