Missing the music in your record collection because your receiver lacks a phono input? Here's a way to get back in the groove. Add the NAD PP 4 Digital Phono/USB preamplifier to your system, and you can connect your turntable to any of your receiver's line-level inputs. And your options don't stop there.
The PP 4's USB port lets you connect your turntable to a computer so you can convert LPs to digital files and transfer your record collection to recordable CDs using the included VinylStudio™ Lite software. A line level input also lets you burn audio CDs from other analog music sources, such as a cassette deck. And this preamp features a recording level control to help optimize the analog-to-digital conversion process.
NAD's PP-4 combines the award winning PP-2I 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-4 also includes the same analog outputs as the PP-2I for connection to an analog stereo system.
The PP-4 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.
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-4 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.
The PP-4 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.
An additional stereo RCA line input allows you to send a standard source to the internal A/D converter and use the included software to record to your computer. A 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-4.
A rear panel stereo RCA output is used for connecting the phono preamp to your home stereo receiver.
A post on the rear panel provides easy grounding for your turntable.
The PP4 front-panel volume control applies to both the MM and MC inputs and the Line In inputs; 0 to -6dB reduces the level via the USB output to the PC to prevent clipping.
The NAD PP-4 operates off of standard household current (120V AC, 60Hz) using the supplied AC power adapter (23.5V DC, 60mA). The external power adapter is separate from the phono preamp to further improve sound quality.
