DIGITISE YOUR VINYL COLLECTION

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 reduces noise and improves 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.

Our PP 4 Digital Phono/USB Preamplifier enables you to digitise your treasured vinyl collections to a PC or Mac. It features inputs for both MM (moving magnet) and MC (moving coil) types for a wide variety of phono cartridges, and there is a line input to allow for the transfer of cassette tapes. 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.
