NAD PP 4 Digital Phono Preamplifier with USB Interface

Get on Board the Big Vinyl Comeback

While physical media has been largely displaced today by digital downloads and streaming, vinyl has definitely been making a resurgence. There's an abundant source of new pop releases and a wide range of reissues on vinyl available.

The NAD PP4 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.

Superb Measured and Sonic Performance

For superb measured and sonic performance, the NAD PP4 features discrete transistor inputs, a 24-volt power supply, subsonic filtering, and extremely accurate RIAA equalization. The rear panel features a selectable MM or MC switch, and there is a second line input to allow for the transfer of cassette tapes (or other line-level analog source).

Digitize Your Record Collection

In addition to being a superb phono preamplifier, the PP4 enables you to digitize your vinyl record collection to MAC or PC. To further reduce noise and improve the analog-to-digital conversion process the PP4 includes a USB interface, shielded USB cable and recording level control. The PP4 offers a complete hardware and software solution and includes VinylStudio Lite Software for ripping LPs and burning audio CDs.

As part of NAD's commitment to the environment, the PP4 features a more efficient 'green' power supply that reduces power consumption. The PP4's Auto Power Down feature saves energy by automatically powering the PP4 to OFF when not in use.

Show your vinyl collection some serious love with the NAD PP4.
