NDX Introduction

1 NDX Introduction

The NDX 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 NDX 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 subsequently described in full detail in Sections 5
to 8. The NDX components are:

A Multi-mode Radio
A UPnP™ Audio Interface
A USB/iPod Audio Interface
A Digital to Analogue converter

Prior to the sections describing NDX components, Section 2 covers its installation, Section
3 describes its operation and Section 4 describes its setup.

1.1 The Multi-mode Radio

The NDX multi-mode radio combines an internet radio
(iRadio) player and an optional FM/DAB (Digital Audio
Broadcasting) tuner. A total of 40 radio stations across all
three modes can be stored as presets. In FM and DAB
mode, stations are tuned by NDX scanning the respective
transmission bands. In iRadio mode the NDX receives
data streams and a list of available radio stations from
a dedicated internet server. iRadio requires broadband
internet access via a home network connection.

The NDX DAB module incorporates full broadcast and
station display capabilities. The FM module is fully RDS
(Radio Data System) capable.

Note: DAB and RDS broadcasts are not available in all

territories.

1.2 The UPnP™ Audio Interface

NDX 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/iPod Interface

NDX incorporates a front panel USB interface socket that
enables audio files stored on USB memory devices and
Apple iPod and iPhone models to be selected and played.

The NDX is compatible with the iPod and iPhone models
illustrated below.

1.4 The Digital to Analogue Converter

NDX 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 TosLink optical socket.

NDX Installation and Connection

2 NDX Installation and Connection

Your NDX should be installed on an equipment stand intended for the purpose. Ensure it is
well ventilated, and do not stand it directly on top of another item of equipment. It should
be installed in its final location before connecting cables or switching on. The NDX has no
standby mode and is intended to be left switched on.

Connecting the NDX to mains power and to a variety of audio peripherals and sources
is described in the following paragraphs. Diagram 2.1 illustrates the NDX rear panel
connection sockets.

The NDX can be upgraded through the use of an external Naim XPS or 555PS power
supply, Connection of an external power supply is illustrated in Diagram 2.2 and
described in Section 2.4.

NDX Installation and Connection

2.3 Mains Power Connection

Connect the NDX to a mains power socket using either the
mains cable supplied or a Naim Power-Line.

2.4 Power Supply Upgrade

The NDX can be upgraded through the use of an external
Naim XPS or 555PS power supply.

If an external power supply is to be used, the link plug on
the rear panel of the NDX should be removed and the
power supply connected in its place using an SXPS Burndy
cable. See Diagram 2.2.

THE SXPS BURNDY CABLE ONLY MUST BE USED TO CONNECT
THE XPS OR 555PS POWER SUPPLIES.

The NDX power switch should be off and the power cable
removed when an external power supply is used. The NDX
is then switched on using the external power supply power
switch.

2.5 FM/DAB Aerial Connection

If the NDX FM/DAB tuner option is fitted it will only be
able to provide high quality FM and DAB radio if a strong,
interference-free radio signal is available. The NDX rear
panel FM/DAB Aerial socket must be connected, via 75
Ohm low-loss coaxial cable, to a suitable aerial. The aerial
should be mounted clear of large obstructions and as high
as possible; ideally on a roof.

Note: Your local retailer should be able to offer advice on

a suitable aerial and aerial installer.

2.6 Audio Inputs and Outputs

2.6.1 Audio Signal Inputs

NDX provides three S/PDIF digital inputs. Connection to the
inputs is made via a variety of socket types. The following
table lists the inputs and their socket types:

Input Socket

dig. 1 Coaxial (BNC)
dig. 2 Coaxial (RCA phono)
dig. 3 Optical (TosLink)

Always use high quality interconnect cables to connect
sources to NDX inputs.

The digital inputs are configured via the NDX Digital Inputs
setup menu. See Section 4.3.6.

2.6.2 Audio Signal Outputs

The NDX provides analogue and digital audio signal
outputs intended for connection to an appropriate
preamplifier or digital to analogue converter input. NDX
output connections are made via the socket types listed
below:

Output Socket

Analogue stereo 5-pin DIN
Analogue stereo RCA phono
S/PDIF digital stereo BNC Coaxial

Note: Output sockets are selected and configured via the

NDX Analogue Outputs and Digital Output setup menus.
See Sections 4.4 and 4.6.

2.7 USB/iPod Interface

The NDX is fitted with a front panel USB interface intended
for the connection of Apple iPod and iPhone models
and USB memory hardware carrying audio files. The USB
interface should not be used for any other purpose.

Depending on the setup options chosen (see Section

4.3.5), iPod and iPhone batteries will be charged when
connected to the USB interface.

2.8 Network Connections

The NDX can be connected to a TCP/IP network via
either a wired or wireless connection. Network connection
enables the NDX to play internet radio data streams
or play audio files stored on UPnP™ servers such as the
Naim UnitiServe and HDX, and appropriately configured
computers and network drives.

2.8.1 Wired Network Connection

The NDX is fitted on its rear panel with a standard ethernet
socket. For wired network connection this socket should
be connected to a spare ethernet socket on your network
router.

Note: Ethernet-over-mains hardware may be used and

provides a simple and convenient method of wired home
network connection. However, depending on mains wiring
factors specific to each home environment, the presence
of network data on the mains supply may compromise
overall system sound quality. If any sound quality
compromise is found to be unacceptable, dedicated
network cabling should be installed or wireless networking
should be employed.

2.8.2 Wireless Network Connection

If NDX is to connect wirelessly to the home network the
supplied Wi-Fi antenna must be fitted to the rear panel
wireless antenna socket. Wireless configuration will also be
necessary before NDX is able to connect to your home
network. See Section 4.5.1.

4

NDX Installation and Connection

2.8.3 Network Settings

The NDX is set up when originally shipped not to require
any on-site TCP/IP configuration but to connect to
a network automatically (it uses DHCP by default).
However, if your NDX has been previously used, its network
configuration may have been altered leaving it unable
to connect automatically. If this appears to be the case
ensure that DHCP is selected in the Network Settings
menu (see Section 4.5 of this manual) and re-start NDX. If
problems still persist contact your retailer, installer or Naim
Audio directly.

Note: Before reporting network connection problems carry

out a Factory Reset operation. Select Reset All Settings
from the Factory Settings setup menu. See Section 4.10.

Note: A NDX switched on without a working wired network

connection will only be able to connect to a home
network wirelessly. To use an ethernet (wired) connection,
switch the NDX off, connect the network and switch it on
again.

Note: For internet radio to operate, the NDX requires

connection to a broadband internet service.

2.9 System Automation

NDX 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 NDX, or for
n-Stream transport functions to control a CD player. To take
advantage of System Automation, connect one of the
NDX rear panel Remote Out sockets to a preamplifier, CD
player or DAC Remote In socket. Use a cable terminated
with a 3.5mm jack plug at one end and a 3.5mm jack or
phono plug as necessary at the other end.

Using both NDX Remote Out sockets, for example, one
connected to a preamplifier and one connected to a CD
player enables comprehensive system control via just one
user interface (handset or n-stream iPhone app).

Note: Stereo and mono 3.5mm jack to 3.5mm jack can

be used for System Automation. If a stereo 3.5mm jack to
phono plug cable is used, connect the left channel phono
plug.

Note: NDX System Automation is switched off by default. A

full description of its configuration and use can be found in
Section 4.9.

2.10 External Control

The NDX is fitted on its rear panel with a 3.5mm jack

Remote In socket and a standard RS232 serial interface

socket. The Remote In socket can be used for RC5 remote
control of the NDX via a wired connection or a remote IR
repeater.

The RS232 socket enables firmware upgrades and
diagnostic tests to be carried out. Contact your retailer for
more information if required.

2.11 Signal Ground Switch

The NDX is fitted on its rear panel with a Signal Ground
switch offering two positions: Chassis and Floating. Select
the Chassis position unless NDX is connected in a hi-fi
system incorporating another earthed source component,
or mains “hum” is audible through the loudspeakers.
Contact your retailer, distributor or Naim for advice if
necessary.

Note: “Connected” in the context above means an

analogue audio signal cable that includes an earth
connection.

Note: All Naim CD players are earthed so the Signal

Ground switch should be set to floating if one is connected
in the system (unless a digital signal connection is used).

Note: The Signal Ground switch setting is not affected by

the use of an external power supply.

No damage will be done if the wrong Signal Ground
position is chosen, however the system sound quality may
be compromised.

2.11.1 General Audio Connection Notes

The NDX mains earth (ground) should always be
connected regardless of what other equipment is used.

Note: If an external power supply is used the NDX mains

earth is connected through the Burndy connection cable
to the power supply mains earth.

A mains earth grounds the chassis and the electrostatic
screen within the transformer, and is only connected to the
signal negative if the Signal Ground switch is set to Chassis.
In order to avoid hum loops, the signal negative of the
whole system should be connected to the mains earth in
one place only.

The Name parameter enables the NDX’s default network
name to be changed.

The Wireless parameter enables a wireless network to be
chosen and joined. See Section 4.5.1 below for detailed
wireless set up notes.

Network Status displays the current network connection
status.

The DHCP parameter enables the NDX network settings
to be modified. In most cases, specifying Yes and leaving
NDX set to DHCP, will be the appropriate option. See
Section 4.5.2 for notes on static address (non-DHCP)
network connection.

Note: Devices installed on a network have an IP address

through which they are identified by all the other items
on the network. DHCP is a set of rules that enable the
automatic allocation of addresses as items are connected
(or switched on while connected) to the network. NDX is
set up by default to use DHCP.

Note: If NDX is connected to the network both wirelessly

and via ethernet (wired), the ethernet connection will take
priority.

is not known, check on the router settings page or with the
person who initially set up the router.

Note: If a router offers multiple security configurations, NDX

will automatically offer only the most secure one.

Note: If WEP security is used the router should be set to

“auto” or “open” authentication.

If the selected network is insecure
and requires no passphrase
or access key to join, NDX
will display an alert message.
Pressing the handset ok/list key
will immediately connect NDX
to the network and display a

4.5.1 Wireless Network
Connection Set Up

If the Wireless parameter is
selected in the Network Settings
menu the Select Network menu
will display a list of the available
networks. An option not to use a wireless connection is
also provided. Use the handset up (5) or down (6) keys
to scroll through the list and the ok/list key to select a
network.

Note: NDX is compatible with most commonly used Wi-Fi

standards. Routers that support 802.11b and 802.11g
will work, however those with 802.11g compatibility are
recommended for best results.

Note: As with any wireless network hardware, NDX

connection reliability will be affected by both network
router performance and Wi-Fi signal quality. To minimise
the possibility of poor connection reliability, NDX should be
connected to network audio sources by no more than one
wireless “leg”. Other “legs” necessary between NDX and
the network audio sources should be wired.

Note: NDX cannot connect to a “hidden” wireless network.

If the selected network is secure
and requires a passphrase or
access key to join, NDX will
display an alert message. Pressing
the handset ok/list key will then
open a text entry screen for entry
of the passphrase or access key.

Use the handset numeric/text
keys to enter the passphrase or
access key taking care to ensure
that the letter case is correct.
Press the handset ok/list key
when text entry is complete. In
the illustration the passphrase is
“flatfish”.

If the network is successfully
joined NDX will display a
confirmation screen.

If an incorrect passphrase or
access key is entered NDX will
display an alert message.

Note: As a security measure, a

router may also require the NDX’s
MAC address to be entered before allowing it to join the
wireless network. This type of security feature is known as
‘MAC address filtering’. The NDX MAC address is shown in
the ‘Factory settings > System Status’ page.

Note: The wireless passphrase/access key is created when

the wireless router is first set up and could be a word or a

The manner in which the UPnP™
server is set up will define how
the audio files and playlists it
holds are listed and displayed. In
most cases the default setup will
list and display files by artist and
album, but list by genre and predefined playlists may also
be available.

Note: Playlists cannot be generated or stored locally by

NDX. To play a playlist it must reside on the UPnP™ server.

Selecting one of the playlist
categories using the up (

5),

down (6) and ok/list keys

will display a menu showing
items that fall into the selected
category. An entire category can
be selected for playback by using the up (5), down (6)
keys followed by the play/pause ( ) key.

Alternatively, selecting a category using the up (5), down
(6) keys followed by the ok/list key will display the full list
of tracks contained within the category. Tracks can then
be selected for playback by using the up (5), down (6)

NDX UPnP™ Audio Inter face

6 NDX UPnP™ Audio Interface

In addition to providing the network connection required for internet radio playback, the
NDX network interface enables audio files stored on UPnP™ servers to be streamed and
played. NDX must be connected, either wirelessly or via ethernet cabling, to a network
router. If the router provides an internet connection it should incorporate a firewall. If NDX
is already connected to a network, begin by selecting the UPnP™ input.

6.1 UPnP™ Servers

UPnP™ servers incorporate a software application that
allows NDX, or any other UPnP™ compatible player, to
play audio stored and streamed by another device on the
network. The UPnP™ server is usually a PC or Mac home
computer, although some Network Attached Storage
(NAS) drives incorporate a UPnP™ application.

Windows Media™ Player version 11 or above incorporates
built in UPnP™ support and a variety of third party UPnP™
applications are also available that are compatible with
both Windows and Macintosh operating systems.

In the case of the Windows UPnP™ server the following
steps must be taken before music can be streamed to
NDX:

• Ensure Windows Media™ Player version 11 or above is

installed.

• Enable Windows Media™ Player file sharing. From the

Media Player Options dialogue select Library > Configure
Sharing… then select Share my media.

• Ensure the firewall is configured to allow file sharing.

6.2 Audio File Compatibility

The audio files stored on the UPnP™ servers attached to
the network may be in MP3, AAC, FLAC, WMA, WAV or
Ogg Vorbis formats. Files must be free of any digital rights
management playback restrictions such as the Apple
iTunes FairPlay system.

6.3 Scanning Servers and Playing Files

When the NDX UPnP™ input
is selected a list of available
UPnP™ servers on the network
will be displayed. The display will
automatically enter list mode so
the handset up (

5), down (6 )

and ok/list keys can be used to
browse and select the desired server.

Note: Allegro Media Server

(shown in the illustrations) is a
UPnP™ Media Server application
that runs on Apple or Windows
PCs and provides access to
media files and iTunes library
contents from UPnP™ media
players such as NDX.
