NAD PP4 Digital Phono USB Preamplifier

With the addition of the PP 4 to your home system, the LPs you cherish the most come alive in the form of expansive and rich sound. Offering superb and measured sonic performance, NAD combines two simple solutions – the PP 4 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. As part of NAD’s commitment to the environment, the PP 4 features a more efficient “green” power supply that reduces power consumption. It also has an Auto Power Down feature that saves energy by shutting off when not in use.

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.
