NAD PP4 - Phono Preamplifier & USB ADC
larger imageClick the image to enlarge

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 – a high quality phono preamplifier and a USB analog-to-digital converter (ADC) – into one small device. It's essential for playing your turntable through stereo amplifiers and AV receivers that lack 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

The PP4 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.


PP 4 VinylStudio Lite

The PP 4 comes with AlpineSoft’s VinylStudio Lite ripping software for Mac and Windows. With VinylStudio Lite you can:

  • Rip LPs into WAV files

Turn your irreplaceable vinyl LPs into digital music you can enjoy anywhere

Missing the music in your record collection because your receiver lacks a phono input? Here's a way to get back in the groove. Add the NAD PP 4 to your system, and you can connect your turntable to any of your receiver's line-level inputs. And your options don't stop there.

The PP 4's USB port lets you connect your turntable to a computer so you can convert LPs to digital files and transfer your record collection to recordable CDs using the included VinylStudio™ Lite software. A line level input also lets you burn audio CDs from other analog music sources, such as a cassette deck. And this preamp features a recording level control to help optimise the analog-to-digital conversion process.

Need a cable?

Why not choose one of our great WireWorld or Naked Cable RCAs to complete the setup with your receiver or amp.
