NAD PP-1 Installation And Operation

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.

Pr blem

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
