Once all mains power, audio input, audio output and control connections have been made,
your Statement amplifiers can be switched on. The NAC S1 and NAP S1 mains power switches are
located on their connection panels adjacent to the mains input sockets. Switch on all connected
source equipment first followed by the NAC S1 preamplifier and finally the two NAP S1 power
amplifiers (or alternative power amplifier(s).
Following initial switch on, the NAC S1 and NAP S1 will take approximately 20 seconds to complete
their start-up routines. During this time the NAC S1 mute button will be illuminated.
While the default settings mean that your Statement amplifiers can be used immediately,
you may wish to modify some settings to suit your particular needs and preferences. The following
paragraphs describe modification of audio input mapping and adjustment of input gain,
including selection of unity gain mode.
N O T E . Should you decide to leave modifying default settings to another time, Section 5 of this manual
describes Statement amplifier operation.

Each of the eight NAC S1 input sockets (3 x 5-pin DIN, 3 x RCA phono pairs, 2 x balanced XLR pairs)
can be mapped to one of the five named NAC S1 inputs: cd, stream, av, phono or aux.
Input mapping can be modified using the down, up and select buttons located on the NAC S1
connection panel.
To modify the input mapping proceed as follows:
• Using the remote handset or the top panel input buttons, select the preamplifier input to be
mapped to an input socket.
• Press and hold the connection panel select button. The indicator adjacent to the currently
mapped input socket will flash.
• Press the connection panel down or up buttons to select each input socket in turn.
The indicator adjacent to each socket will flash as the socket is selected.
• When the indicator corresponding to the input socket required flashes, press the select button
or the top panel input button. The input socket will now be mapped to the selected input.
