note: The NAC 252 AUX 2 input is provided with two
sockets. The lower socket, fitted on delivery with a
blanking cover, is intended for use with a Naim Audio RCA
Phono stage and incorporates an appropriate DC power
supply. The two sockets must not be used simultaneously.
note: The RS232/comms interface is an optional
upgrade. It can be specified at time of order or fitted
retrospectively. Contact your local representative or Naim
