NAD PP4 Digital Phono / USB Preamp

NAD PP4 Digital Phono / USB Preamp 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 analog-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.
