The Phono Preamp That Does It All

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 into the PP 4; digital phono and USB preamplification into one small device. This unit makes 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.

About NAD

In 1972, a new kind of audio company was born. NAD took form when a large group of audio-industry importers in Europe, all music lovers, set out to develop products that cut through the industry hype. The goal of NAD was to prove that excellent sound quality and excellent value could exist together. It was a formidable goal – some of the most reputable electronics brands of the time were unaffordable to most, while the affordable spectrum of the market was dominated by poor quality imports from global electronics giants. NAD’s founders remained undeterred and their original vision led to an inspiring story of how a group of specialty audio mavericks took on the Goliaths of the audio industry to carve out a unique place of their own.

NAD is dedicated to innovation, performance, value, and simplicity in all their products.

Why do I need a preamp?

A phono pre-amplifier is designed to boost the signal from a turntable or record player before the signal is passed to your Hi-Fi amplifier or receiver. Typically the signal output from a turntable or record player is quite weak, and it's required to be boosted before it hits the main amplifier of your stereo or hi-fi unit.

On the Flip-Side...

Some hi-fi amplifiers or receivers have a dedicated "phono" input and some modern turntables have a "line" level output - this simply means they have a phono preamp built in and an external one is not necessary. However if your system or player doesn't have this feature built in, or if you want to use a high-end one, you'll need a separate preamp (like this one).
