INSTALLATION & OPERATION OF NAD PP 2
• Please make sure all ancillary equipment is turned off, and that the NAD PP 2 is not yet connected to its dedicated Power Supply.
• Connect the leads from the turntable to the appropriate input sockets; MC for moving coil, MM for movingmagnet cartridge on the back of the PP 2. 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. Once the turntable leads are connected, set the MC/MM switch on the back of the PP 2 to the correct input setting.
• Connect suitable RCA leads from the NAD PP 2 to the amplifier 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 2 to an input marked
Phono or turntable. Again, make sure to connect the Red plug to the Right channel, and the White plug to the Left channel of the amplifier or receiver.
• If the lead from your turntable is equipped with a separate earth (GND) lead, connect this directly to a ground connection on the PP 2. Use the thumb screw terminal "GND" which provides the grounding.
• Connect the dedicated Plug-in Power Supply to the NAD PP 2 (marked 24V).
• Insert the Plug-in Power Supply to a live mains socket; the green LED on the NAD PP 2's front panel will light up.
• Installation is now complete. As the power consumption of the NAD PP 2 is negligible, it can always be left switched on. It is recommended however that you disconnect the Plug-in Power supply from the
mains if you are not going to use the NAD PP 2 for a prolonged period of time (such as a holiday).
To play a record:
• Ensure that the volume on the amplifier or receiver is set to a low level.
• Select the input on the amplifier or receiver to which the NAD PP 2 is connected, use amplifier or receiver and turntable as normal, set to desired volume level.
Troubleshooting:
Always turn down the volume to a low level or turn off all equipment before checking.
Problem
• No sound
• Sound in one channel only
• Hum or Buzz noise

Cause
• Plug in dedicated Power Supply
• Select input to which NAD PP 2 is connected
• Check all connections (make sure to turn off all equipment beforehand)
• Check to see if the MM/MC selector switch is set correctly for your type
of turntable cartridge (make sure to turn off all equipment beforehand)
• Check all connections (make sure to turn off all equipment beforehand)
• If connected, disconnect turntable's earth lead from amplifier / receiver
• Move NAD PP 2 and cables further away from other equipment
• Check to see if the MM/MC selector switch is set correctly for your type
of turntable cartridge (make sure to turn off all equipment beforehand)
