INSTALLATION & OPERATION OF NAD PP 1
• Please make sure all ancillary equipment is turned off, and that the NAD PP 1 is not yet connected to its dedicated Power Supply.
• Connect the leads from the turntable to the input sockets on the back of the NAD PP 1. Make sure you connect the Right channel to the Right input; the Left channel to the Left input; Normally, a Red connector
denotes the Right Channel; White or Black denotes the Left channel.
• Connect a suitable lead from the NAD PP 1 to the amplifier or receiver. Always use a so-called 'Line-Lever input, such as CD, AIDE, Tuner or Tape.
Never
connect the lead from the NAD PP 1 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 lead, connect this directly to a ground connection on the amplifier or receiver. Usually, the metal back panel of an amplifier provides grounding
by means of a small terminal. If this is not available, you can connect the earth cable directly to the back panel, by means of placing the wire under a screw in direct contact with the metal of the back panel;
for instance, the screw holding the lop cover to the back panel. Almost all receivers provide a ground terminal with the antenna input; this terminal is usually marked 'GND' or with the symbol “---|---“. If an
antenna is connected, you can simply add the wire to this terminal.
• Connect the dedicated Plug-in Power Supply to the NAD PP 1 (marked 15V).
• Insert the Plug-in Power Supply to a live mains socket; the green LED on the NAD PP 1's front panel will light up.
• Installation is now complete. As the power consumption of the NAD PP-I 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 1 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 1 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.

o
• No sound
• Sound in one channel only
• Hum or Buzz noise
Cause
• (LED is not lit) Power Supply not connected to either NAD PP 1 or mains socket
• (LED is lit) Wrong input on amplifier / receiver selected
• Plugs from turntable and / or lead from PP 1 to amplifier / receiver sockets
not property fitted
• Plugs from turntable and / or lead from PP 1 to amplifier / receiver sockets
not properly fitted
• No connection from turntable to ground
• Earth loop present
• Interference from nearby equipment
Solution
• Plug in dedicated Power Supply
• Select input to which NAD PP 1 is connected
• Check all connections (make sure to turn off all equipment beforehand)
• Check all connections (make sure to turn off all equipment beforehand)
• If present, connect earth lead from turntable directly to amplifier / receiver
• If present, disconnect turntable's earth lead from amplifier / receiver
• Move NAD PP-I and cables further away from other equipment
