Offering superb measured and sonic performance, NADs two simple solutions, the PP 4 Digital Phono/USB Preamplifier makes it easy to add phono to many of todays 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 NADs 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 4s Auto Power Down feature saves energy by automatically powering the PP 4 to OFF when not in use.
