Introduction
1 Introduction
The NDS is a highly capable network and digital audio player that will repay time and 
effort spent on installation and setup. We strongly recommend that you read this manual.
The NDS incorporates four distinct audio components, each routed to analogue or digital 
outputs intended for connection to an appropriate preamplifier input. Each component 
is introduced in the paragraphs below and the first three subsequently described in full 
detail in Sections 5 to 7. The components are:
An Internet Radio
A UPnP™ Audio Interface
A USB Audio Interface
A Digital to Analogue converter
Prior to the sections describing NDS components, Section 2 covers installation, Section 3 
describes operation and Section 4 describes setup.
1.1 The Internet Radio
The NDS internet radio requires high speed internet access 
via a home network connection. When connected to 
the internet the NDS receives data streams and a list of 
available radio stations from a dedicated internet server. 
Up to 40 internet radio stations can be stored as presets 
(favourites).
1.2 The UPnP™ Audio Interface
NDS can connect to a home network and play audio files 
stored on UPnP™ drives such as the Naim UnitiServe or on 
PC and Mac computers.
1.3 The USB Audio Interface
NDS incorporates a front panel USB interface socket that 
enables audio files stored on USB memory devices to be 
selected and played. 
1.4 The Digital to Analogue Converter
NDS incorporates a three input digital to analogue 
converter able to handle S/PDIF format digital audio at 
up to 24 bit and 192kHz resolution. The three DAC inputs 
comprise one coaxial BNC socket, one coaxial phono 
socket and a TosLink optical socket. The analogue output 
is available on both 5-pin DIN and phono sockets.
