· Switched Line Level Input
· Highly accurate Analog-to-Digital Converter
INSTALLATION AND OPERATION
CONNECT THE TURNTABLE TO THE PP 3i
1 Please make sure all ancillary equipment is turned o and that the NAD
PP 3i is not yet connected to its dedicated Power Supply.
2 Connect the leads from the turntable to the appropriate input sockets
on the back of the NAD PP 3i - MC for moving coil, MM for moving
magnet cartridge. Make sure you connect the Right channel to the
Right input; the Left channel to the Left input. Normally, red connector
denotes the Right Channel; white denotes the Left channel.
3 Once the turntable leads are connected, set the MC/MM switch on the
back of the NAD PP 3i to the correct input setting.
CONNECT THE PP 3i TO AN AMPLIFIER OR RECEIVER
1 Connect suitable RCA leads from the NAD PP 3i to the amplier or
receiver. Always use a so-called “Line-Level” input such as CD, AUX,
Tuner or Tape. Never connect the lead from the NAD PP 3i to an input
marked Phono or turntable.
· USB interface to PC for Vinyl-to-Hard Drive recording, USB cable
included
· Analog Line Level Output
· External 24V DC power supply
CONNECT THE POWER SUPPLY TO THE PP 3i
1 Connect the dedicated Plug-in Power Supply to the NAD PP 3i
(marked24V).
2 Insert the Plug-in Power Supply to a live mains socket; the blue LED on
the NAD PP 3i’s front panel will light up. Installation is now complete.
As the power consumption of the NAD PP 3i is negligible, it can always be
left switched on. It is recommended however that you disconnect the Plugin Power Supply from the mains if you are not going to use the NAD PP 3i
for a prolonged period of time (such as a holiday).
CONNECT THE PP 3i TO A PERSONAL COMPUTER
1 Connect the supplied USB cable (or any approved USB cable) between
the USB socket of the PP 3i and the USB socket of your PC. Your PC
should automatically recognize the PP 3i as a “new device” - the amber
LED of the PP 3i will illuminate conrming the connection.
2 Again, make sure to connect the red plug to the Right channel, and the
white plug to the Left channel of the amplier or receiver.
3 If the lead from your turntable is equipped with a separate earth (GND)
lead, connect this directly to a ground connection on the NAD PP 3i.
Use the thumb screw terminal “GND” which provides the grounding.
2 Place the supplied “Vinyl Studio” CD in your PC’s disc drive and follow
the instructions to load the program into your PC.
3 Open the program and follow the instructions to get started recording
your LP’s to your PC’s Hard Disc Drive or other digital device.
Always turn down the volume to a low level or turn o all equipment before checking.

• Check to see if the MM/MC selector switch is set
correctly for your type of turntable cartridge (make
sure to turn o all equipment beforehand).
• Plugs from turntable and/or lead from NAD PP 3i to
amplier/receiver sockets not property tted.
Sound in one channel only. • Plugs from turntable and/or lead from NAD PP 3i to

Hum or Buzz noise. • No connection from turntable to ground. • Connect the turntable’s earth (GND) lead directly to
a ground connection or to NAD PP 3i’s thumb screw
terminal “GND” which provides the grounding.
• Earth loop present. • If connected, disconnect turntable’s earth lead from
amplier/receiver.
• Interference from nearby equipment • Move NAD PP 3i and cables further away from other
equipment.
