Product Research


Overview: NAD's PP-3i combines the award winning PP-2 MM/MC Phono Preamp with a high quality Analog-to-Digital converter and USB interface. Utilizing VinylStudio Lite PC Software, you can convert records and tapes to CD. The PP-3i also includes the same analog outputs as the PP-2 for connection to an analog stereo system.

RIAA EQ: The PP-3i phono preamp consists of a low noise discrete MC preamp followed by a low noise opamp-based RIAA MM stage incorporating a 12dB/octave infrasonic filter to attenuate turntable "rumble" noise. The output feeds the Line Output as well as the soft clipped input of an A/D converter with USB Output. This can be connected to any PC for recording from vinyl disc to a hard drive. The built-in passive equalizer curve follows the RIAA standard within 0.3 dB, measured from 50 Hz to 20 kHz.

USB: Using the USB Type-B port on the front panel, the phono signal can be routed to your computer; with the included VinylStudio Lite software LPs are easily converted to CD (Macintosh version available on NAD's web site). The PP-3i has an analog to digital converter (A/D) that optimizes the gain for the best signal to noise ratio and lowest distortion. The USB output is 16-bit linear PCM signal sampled at 48 kHz.

Note: In order to save the tracks as MP3 or MP4/AAC files, you must upgrade to the full version of VinylStudio Lite software.

Cartridge: The PP-3i accepts inputs from either moving magnet (MM) or moving coil (MC) cartridges. On the rear panel there are separate RCA inputs for MM and MC, and a switch to choose which you are using.

Line Input: The RCA line inputs allow you to send a standard source to the internal A/D converter and use the included software to record to your computer. Another switch on the rear panel selects the phono or line input. The line input can also replace the input on your receiver taken by the PP-3i.

Ground: A post on the rear panel provides easy grounding for your turntable.
