The NAC S1 provides a variety of interface connection sockets that enable both its control
integration with the NAP S1 power amplifier and its integration with wider audio system
automation, remote control schemes and home automation technology. Diagram 2.2 illustrates
the NAC S1 connection panel. The connection panel interface sockets comprise the following:
C A N B U S . Three RJ45 CAN bus sockets are provided to enable control integration of the NAC S1
with NAP S1 power amplifiers and potentially with CAN bus equipped audio source components.
If your NAC S1 is to be used with NAP S1 power amplifiers, connect the left-hand NAC S1 CAN bus
socket to the right channel NAP S1 and the right-hand NAC S1 CAN bus socket to the left channel
NAP S1.
N O T E . A 560mm CAN bus cable is supplied with each NAP S1 power amplifier. Your Naim retailer
will be able to supply longer cables if required.
The third NAC S1 CAN bus socket can be used for control integration with other CAN bus
equipment but also doubles as RS232 control interface socket and enables the NAC S1 to be
integrated with RS232 based home automation systems. Your Naim retailer will be able to
advise on both CAN bus and RS232 based control integration.
1 2 V T R I G G E R . The NAC S1 is equipped with two 3.5mm jack socket 12V trigger outputs and one
trigger input. These 12V trigger sockets enable control integration with appropriately equipped power
amplifiers and other ancillaries.
If your NAC S1 is to be used with mono power amplifiers equipped with 12V trigger inputs,
connect the right-hand NAC S1 trigger output to the left channel power amplifier trigger
input, and the left-hand NAC S1 12V trigger output to the right channel power amplifier trigger
input. If your NAC S1 is to be used with a stereo power amplifier equipped with a 12V trigger
input, connect either of the NAC S1 trigger outputs to the power amplifier trigger input.
N O T E . CAN bus should be used in preference to 12V trigger control for integration of the NAC S1
and NAP S1.
Your Naim retailer will be able advise on 12V trigger control and to supply control cables of
the appropriate length.
R C 5 . The NAC S1 is equipped with 3.5mm jack RC5 input socket to enable integration with wired
remote control systems. Your Naim retailer will be able advise on RC5 control and to supply control
cables of the appropriate length.
M I N I U S B . A mini-USB socket is fitted to the NAC S1 to facilitate firmware updates. Your Naim
retailer will be able to advise on firmware updates and procedures.
