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 Stageline or Prefix 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 Audio directly for further information.
