NDS Quick Start Guide
English
1 Installing and Connecting
• The four transit screws located on the underside of the NDS must be carefully removed
before	use.	Do	not	invert	the	NDS	to	remove	the	transit	screws	but	work	from	the	underside	
by	positioning	it	at	the	edge	of	a	table.	The	transit	screws	must	be	replaced	if	the	NDS	is	to	
be	re-packed	or	shipped.	
Do not invert the NDS during or following transit screw removal.
• Following transit screw removal, stand the NDS on an appropriate, level and stable surface.
Make sure it is adequately ventilated.
• The NDS requires an external XP5 XS, XPS or 555PS power supply connected to one (XP5
XS,	XPS)	or	both	(555PS)	of	its	power	supply	input	sockets.	Use	only	the	Burndy	cable	or	
cables	supplied	with	the	power	supply.	If	an	XP5	XS	or	XPS	power	supply	is	used	it	should	
be	connected	to	NDS	Power	Supply	Input	1.	If	a	555PS	power	supply	is	used	it	should	be	
connected	to	both	NDS	Power	Supply	Inputs	1	and	2.	The	link	plug	must	remain	fitted	to	
Power	Supply	Input	2	unless	a	555PS	power	supply	is	used.	Do	not	switch	on	the	external	
power	supply	until	all	required	NDS	connections	are	made.
• Identify the
Signal Ground Switch
and select the “chassis” option unless the NDS is
connected	in	a	hi-fi	system	incorporating	another	earthed	source	component	(all	Naim	CD	
players,	for	example),	or	mains	“hum”	is	audible	through	the	loudspeakers	when	the	NDS	is	
switched	on.
• To play audio from a
UPnP
™ server or from internet radio stations, the NDS
network socket
must be connected to a router using an Ethernet cable, or its
Wi-Fi Antenna
must be fitted.
Internet radio also requires a high-speed internet connection.
• If the NDS is to play audio files stored on a
USB
device, connect it using an appropriate
cable, if necessary, to the front panel USB socket.
• If any external S/PDIF digital audio sources are to be used with the NDS, connect them,
using the appropriate BNC coaxial, phono coaxial or optical cables, to the
digital
inputs.
• Connect one of the NDS outputs to an appropriate preamplifier or external DAC input. The
NDS	DIN	output	is	the	default	active	analogue	output.	To	select	an	alternative	analogue	
output,	press	the	handset	setup	key	( )	once	the	NDS	is	switched	on	and	select	
Analogue
Outputs
. Select
Digital Output
to activate the digital output.
• NDS control can be linked using
System Automation
to the control of some Naim
preamplifiers,	CD	players	and	the	Naim	DAC.	System	Automation	enables	for	example,	
preamplifier	inputs	to	be	selected	via	the	NDS,	or	for	n-Stream	transport	functions	to	control	
a	CD	player.	To	take	advantage	of	System	Automation,	connect	one	of	the	NDS

Important:
XPS power supplies
with serial numbers below 
188015 are not compatible 
with the NDS and should not 
be used. Contact your local
