    Show your vinyl collection some serious love. Offering superb measured and sonic performance, NAD’s two simple solutions, the PP 4 Digital Phono/USB Preamplifier makes it easy to add phono to many of today’s stereo amplifiers and AV receivers that have either eliminated the phono input or included a low quality circuit for attaching your turntable. As part of NAD’s commitment to the environment, the PP 4 features a more efficient “green” power supply that reduces power consumption. The PP 4 goes one step further with a USB interface, shielded USB cable and recording level control which combine to reduce noise and improve the analogue-to-digital conversion process. The PP 4’s Auto Power Down feature saves energy by automatically powering the PP 4 to OFF when not in use. The PP 4 also includes VinylStudio Lite Software for ripping LPs and burning audio CDs. The PP 4 Phono-to-USB Preamp offers a complete hardware and software solution with exceptional flexibility to record from LP or tape. PP 4 VinylStudio Lite
