PP 4 Digital Phono/USB Preampli er
PP 2i Phono Preampli er
Show your vinyl collection some serious love. Offering superb measured and sonic performance, NAD’s two simple
solutions, the PP 4 Digital Phono/USB Preampli er and the PP 2i Phono Preampli er, make it easy to add phono to many
of today’s stereo ampli ers and AV receivers that have either eliminated the phono input or included a low quality circuit for
attaching your turntable. As part of NAD’s commitment to the environment, both the PP 4 and PP 2i feature a more ef cient
“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 combine to reduce noise and improve the analogue-to-digital conversion
process. The PP 4’s Auto Power Down feature saves energy by automatically powering the PP 4 to OFF when not in use.
