2 Connections
It is important for both safety and performance that
the standard cables supplied are not modified.
2.1 Interconnect Cables
If options are available with your equipment and installation,
DIN interconnect sockets should be used in preference to RCA
Phono sockets. One end of each Naim interconnect cable is
marked with a band to establish its correct orientation. The band
denotes the end that connects to the signal source.
Interconnect plugs and sockets should be kept clean and free
from corrosion. The easiest way to clean them is to switch off
the equipment, pull the plugs out of their sockets, and push
them back in again. Contact cleaners and “enhancers” should
not be used as the film they tend to deposit may degrade the
sound.
2.2 Loudspeaker Cables
Loudspeaker cables are vitally important and your dealer should
make them up to suit your installation. The cables should
each be at least 3.5 metres long and of equal length. The
recommended maximum is normally 20 metres although longer
cables may be viable with some Naim amplifiers. Contact your
dealer or Naim Audio for advice.
Many Naim amplifiers are designed only to work with Naim
loudspeaker cable and using alternatives may degrade the
performance or even damage the amplifier. Naim loudspeaker
cable is directional and should be oriented so that the printed
arrow points towards the speakers. The amplifier/loudspeaker
connectors supplied are designed to make a robust electromechanical connection and to comply with European safety
regulations. They should be used in preference to alternatives.
3 Mains Power Connection
Where fused plugs are used 13 amp fuses should be
fitted. Fuses of a lower rating will fail after a period
of use. Do not wire voltage dependent resistors or
noise suppressors into mains plugs. They degrade the
mains supply and the sound.
1 Equipment Installation
Normally your Naim Audio equipment will have been installed by the dealer who sold
it to you - even if you live outside their immediate vicinity. In any event however
your dealer is responsible for making sure that the system performs as it should.
Information given here is not intended to reduce this responsibility in any way.
Introduction
This manual covers the DVD5 DVD player and the AV2 Audio Processor. It
3.1 Mains Plug Wiring
In some territories a mains plug may need to be
fitted to the supplied mains lead. As the colours of
the wires in the mains lead may not correspond with
the coloured markings identifying the terminals in the
plug proceed as follows:
The wire which is coloured
must be
connected to the terminal in the plug which is marked by the
letter
or by the safety earth symbol or coloured
.
The wire which is coloured
must be connected to the
terminal in the plug which is marked with the letter
.
The wire which is coloured
must be connected to the
terminal in the plug which is marked with the letter
.
3.2 Non-rewirable Mains Plugs
If a non-rewirable plug is cut from a mains lead (for whatever
purpose) the plug
be disposed of in a way to render it
totally useless. Considerable shock hazard exists if the cut-off
plug is inserted into a mains outlet.
3.3 Mains Circuits and Cables
A hi-fi system usually shares a mains circuit with other
household equipment some of which can cause distortion of the
mains waveform. This distortion can in turn lead to a mechanical
hum from power amplifier and power supply transformers.
Naim transformers are large in size with heavy gauge windings,
making them relatively sensitive to such distortion, and it may
be necessary to take account of transformer hum when siting
your equipment.
Transformer hum is not transmitted through the speakers and
has no effect on the performance of the system; however, a
separate mains circuit may reduce it. Such a circuit (ideally with
a 30 or 45 Amp rating) will also improve system performance.
Advice on the installation of a separate mains circuit should be
sought from a qualified electrician.
Do not substitute alternative mains leads and plugs to
those supplied. They are selected to offer the best possible
performance.

4 General Installation
Naim equipment is designed to offer the finest
performance possible avoiding compromise wherever
practical. This can lead to circumstances that may
be unfamiliar. The notes that follow contain advice
specifically related to Naim equipment as well as
more general warnings about the use of domestic
audio products. Please read them carefully.
4.1 Siting The Equipment
In order to reduce the risk of hum audible from the
loudspeakers, power supplies and power amplifiers should be
located a reasonable distance away from other equipment. The
maximum separation distance for connected equipment is that
allowed by the standard interconnect lead.
Some Naim equipment is extremely heavy. Ensure that your
equipment rack or table can easily support the weight and is
stable.
4.2 Switching On
Source components and power supplies should be switched on
before the power amplifiers. Always switch amplifiers off and
wait a minute before connecting or disconnecting any leads.
Always use the power switch on the product rather than a mains
outlet switch.
A “thump” may be heard from the loudspeakers as power
amplifiers are switched on. This is normal, will not cause any
loudspeaker damage and does not point to any fault or problem.
A mild “pop” may also be heard shortly after power amplifiers
are switched off.
4.3 Running In
Naim equipment takes a considerable time to run in before
it performs at its best. The duration varies, but under some
conditions the sound may continue to improve for over a month.
Better and more consistent performance will be achieved if
the system is left switched on for long periods. It is worth
remembering however that equipment left connected to the
mains can be damaged by lightning.
4.4 Radio Interference
In some circumstances, depending on where you live and the
earthing arrangements in your home, you may experience
radio frequency interference. Controls on broadcasting in some
territories allow very high levels of radio frequency radiation
and both the choice and exact siting of equipment may be
critical. Susceptibility to radio frequency interference is related
to the wide internal bandwidth necessary for high sound quality.
Systems incorporating moving coil phono preamplifiers and
active crossovers are more likely to suffer. A radio frequency
filter kit is available for some Naim equipment but sound quality
will be progressively compromised as more elements of the
kit are fitted. In situations of extreme radio interference Naim
equipment may be unsuitable.
4.5 Non-standard Cables
Use of non-standard speaker cables or interconnects may
invalidate your guarantee.
4.6 Lightning Precautions
Your Naim hi-fi system can be damaged by lightning. Power
amplifiers are particularly at risk and should be turned off and
disconnected from the mains when there is risk of lightning
strike. For complete protection all mains plugs and any aerial
cables should be disconnected when not in use.
4.7 Liquid Precautions
Equipment must not be exposed to dripping or splashing and no
objects filled with liquid, such as vases, should be placed on the
equipment.
4.8 Equipment Fuses
Mains powered Naim Audio equipment is fitted with a mains
input fuse on the rear panel adjacent to the mains input socket.
Replace it if necessary only with the spare fuse supplied or
with identical fuses. Repeated failure of this fuse points to an
equipment or system fault that should be investigated by your
dealer or at the factory by Naim itself.
4.9 Problems?
Consumer protection varies from country to country. In
most territories a dealer must be prepared to take back
any equipment he has sold if it cannot be made to work
satisfactorily. A problem may be due to a fault in the system or
its installation so it is essential to make full use of your dealer’s
diagnostic skills. Please contact your local distributor, or Naim
Audio directly, if any difficulties cannot be resolved.
Some Naim equipment is made in special versions for
different territories and this makes it impracticable to arrange
international guarantees. Please establish the local guarantee
arrangements with your dealer. Contact Naim Audio directly for
help and advice if necessary.
4.10 Repairs and Updates
It is essential that repairs and updates are only carried out
by an authorised Naim dealer or at the factory by Naim itself.
Many components are custom made, tested or matched and
appropriate replacements are often unobtainable from other
sources.
Direct contact to Naim for service or update information should
be made initially through the Service Department:

Please quote the product serial number (found on its rear panel)
in all correspondence.
Introduction

DVD5 and AV2
5 Product Introduction
This manual covers installation and operation of the DVD5 DVD player and the AV2
audio processor. Both products are fundamentally straightforward in use, however
their versatility and comprehensive functionality mean that a little time spent
reading will help ensure problem-free use.
The DVD5 section of the manual covers use of the player as a stand-alone product
as well as when connected to and integrated with an AV2. This section also covers
the DVD5 Multi-channel Card audio upgrade (McC) option.
The AV2 section of the manual covers use of the processor as a stand-alone product.
The AV2 feature-set and operation described in this manual refers to units
incorporating software release Version 01-04 or later. Contact Naim Audio directly or
your local representative for information on software identification and updates.
Both the DVD5 and AV2 should be installed on dedicated equipment stands intended
for the purpose. Care should be taken to ensure that they are level. Do not switch on
until all input and output connections are made.
Following this introduction, the manual is divided into the following sections.

6 DVD5 Media, Outputs and Connections
6.1 DVD5 Media
The DVD5 supports NTSC and PAL DVD, “Red Book” Audio
CD, DVD-A Stereo, DVD±R, DVD±RW, CD-R, CD-RW and copy
protected Audio Discs. With the addition of the Multi-channel
Card upgrade DVD-A multi-channel is also supported.
The large variety of disc manufacturing processes and formats
now available means that on rare occasions a disc falling into the
one of the above categories may still not play correctly. You should
return the disc to the retailer if this occurs.
DVD region coding is sales territory dependent and is specified
on the rear panel of the player.
6.2 Video Outputs
The DVD5 can provide video outputs in a number of different
formats on a variety of connection sockets. Each format and
socket is appropriate for alternative display types - TV, CRT
Monitor, TFT Monitor, Plasma, Projector, etc - and it is important
for the best picture quality that the appropriate socket is used.
Table 6.4 below lists, in order of preference, connection formats
for any display device. Select, from the connection options
available on your display, the one nearest the top of the list.
6.3 Audio Outputs
The DVD5 provides digital audio output via both coaxial and
optical connectors. There are two coaxial and two optical
connectors on the DVD5 rear panel. Each carries the same
signal. Digital audio should be connected to either the coaxial or
optical input of an appropriate AV processor. The coaxial option
is likely to give better results.
Stereo analogue audio output is available on both DIN and
RCA-Phono sockets. Multi-channel audio, available when the
Multi-channel Card is fitted is delivered via a pair of five pin DIN
sockets.
The analogue audio signal available from the SCART
interface is not of optimum quality and is only suitable for uncritical
monitoring, setup or diagnostic use.
7 DVD5 Setup
Once connected to a display and audio system the
DVD5 must be set up appropriately before use.
The player will switch on initially in
mode with a flashing
display indicator. When the indicator stops flashing the player is
ready for use. A single press on the front panel or handset
or
buttons, or on the handset
keys will
wake the player.
To switch the player into standby mode, press and hold the front
panel
buttons, or press the handset
Standby mode reduces power consumption when the player
is not in use.
7.1 Initial Video Options
As the display on the player itself provides only minimal
information during set up, the video display should be switched
on and the appropriate channel selected so that the playergenerated On Screen Display is available. Two initial set up
options may however need to be adjusted before the display will
operate correctly. These options select between
options. The default state for
the NTSC/PAL option is
options only apply to the player’s
output sockets, the options being

selected in Section 7.1.1.
The selection of
depends on the capability of
the display device connected and the choice between Interlaced
and Progressive Scan video. Many displays are limited either to
PAL or NTSC for Interlaced video and if this is the case for your
display the appropriate option should be selected. Similarly,
many displays do not support PAL for Progressive Scan video so
selection of the NTSC option may well be necessary when using
Progressive Scan - even if PAL is used for Interlaced video. The
DVD5 will convert PAL encoded programme material to NTSC
if NTSC is selected, or convert NTSC to PAL if PAL is selected display quality may however suffer.
If your display supports both
option
should be used. Auto switches the DVD output to NTSC or PAL
depending on the disc format. The combination of a multistandard display and the
option ensures the highest video
quality as no format conversion need take place.
7.5.2 Black Level
adjustment is available when
output is
selected. Black Level defines the brightness level at which
image information will be displayed as black. A video brightness
signal is measured in IRE units on a scale from 0 (black) to 100
(white). In American NTSC encoding the value of 7.5 IRE is the
“black level cutoff”.
Black level adjustment only affects NTSC material.
7.5.3 SCART Settings
The player’s
output connector carries video signals
in both
forms with two alternate
varieties of the component format -
- available.
If using component video from the SCART connector, select the
variety appropriate to the display connected.
Composite and component video and the various signal
formats are explained in Section 14 of this manual.
7.5.4 Test Patterns
Provides three display
intended to help calibrate
the player and display combination and ensure optimum
performance. The Test Patterns are primarily intended for
advanced users or video service engineers. Make a note of all
display and DVD5 settings prior to making any adjustments, and
ensure the display user manual is available for reference.
It is not always necessary to make calibration adjustments
based on the test patterns. The DVD5 and display default settings
will in the majority of cases provide excellent results.
Help text for each test pattern is available by pressing the
handset menu key.
The player must be in stop mode to display the test patterns.
Adjust the display’s horizontal, vertical, aspect ratio and zoom
controls until the test pattern is central and spills over the edge
of the display by approximately 5%. On a wide-screen display the
circle labelled 16:9 should appear undistorted.
Adjust the display’s brightness until the 0% box looks black.
Adjust the display’s contrast until the 100% box is a clear brightundistorted white. Ensure no two of 5% boxes appear the same.
The display must be viewed using a 47b blue separation filter.
Adjust the display’s colour and tint/hue control until the four
large boxes (1, 2, 3 and 4) appear the same shade of blue.
7.5.5 Lip Sync (Audio/Video delay)

the full height of the display but dynamically pans the material
to ensure that the important information is always displayed. The
option displays the material’s full width but leaves a
proportion of the display above and below the picture unused.
7.5.7 Video Outputs Off
Enables unused video sockets to be selectively switched off
during playback. Switching off the video sockets will improve
sound quality of audio CD and DVD-A material.
All video outputs will operate when player is in stop mode or
when the OSD menu is displayed.
7.6 High Definition Video Setup
Selection of
from the top level
menu generates a second level menu comprising the options
listed below.
The
menus enable selection of the signal
format to be output from the player’s
sockets.
Generally, the signals available from the BNC sockets provide
improved quality over the SCART and S-Video outputs through
improved digital to analogue conversion and extra image
adjustment functions.
7.6.1 Colour Format
The
sub-menu enables selection of the video
signal
(RGB, YPbPr, etc). The options available
will depend on the selection made in the previous menu.
The various video colour formats are explained in Section 14
of this manual.

7.6.2 Motion Compensation
is a function of progressive scan video
processing that overcomes the visible artifacts that can result
when interlaced video data (see Section 14) is de-interlaced
for conversion to progressive scan. If a video scene contains
elements in motion, the two fields of an interlaced image cannot
simply be combined for progressive scan as the time delay
between the fields will result in visible distortion of the moving
image - it will appear jagged. Motion Compensation overcomes
the distortion by dynamically interpolating between differences in
the fields of data. If there is no movement in a scene however,
the interpolation may result in a loss of image sharpness.
The
menu provides three options

majority of programme material.
may be appropriate
to material featuring intense motion, or still images respectively.
7.6.3 Film Mode
enables the player to optimise the display of
programme material that has been converted from film to video
(DVD) format. Film Mode should be selected for programme
material that is known to be derived from a cine-film original.
Leaving Film Mode selected for original video material may still
result in satisfactory display, however, it should be de-selected
for this type of material if motion or sync problems occur.
7.6.4 30 fps (frames per second) Detection

should be selected for
most programme material unless motion or sync errors are
unacceptable. Increasing Edit Compensation will result in
smoother display but reduced picture quality.
7.6.6 Picture Adjustment
Three separate
sub-menus are available.
One that provides adjustment of the player’s
output, one that provides adjustment of the player’s
output and one that is common to both.
Each signal channel of the
outputs can be independently
adjusted. For example, to emphasise red, green or blue tones in
an
picture boost the R, G or B channels respectively.
adjustment covers luminance and saturation only.
The picture adjustments common to
adjustments enable the picture to be properly centred
in the display screen.
adjustment provides compensation for the timing errors
that can occur between the colour and brightness elements of
a video signal. Errors are most likely to be visible if the player is
required to carry out intensive processing to generate a display
signal. YC Delay is best left at its default adjustment unless
picture abnormalities that cannot be corrected by any other
means are apparent.
Offset and YC Delay adjustment made from this menu will
also be reflected in the player’s DVI output.
No picture adjustment is available on the player’s SCART and
S-Video outputs.
7.7 Audio/AV2 Setup
Selection of
from the top level menu generates
a second level menu comprising the options listed below. The
availability of options in the second level menu depends on
either the installation of a
When a DVD5 is connected to an AV2, adjustment of Audio
Setup parameters actually adjusts AV2 functions. The AV2 front
panel or handset setup interface is disabled while the DVD5 on
screen setup menus are displayed. If the AV2 front panel or handset
interface is subsequently used to adjust any Audio Setup parameters
the DVD5 menu will update automatically.

must be connected together via an interface cable in
addition to the appropriate signal cable. Connection of
the interface cable is illustrated in Section 11.2
With a DVD5 and AV2 connected the DVD on-screen display
functions can be used to view and adjust AV2 setup and
operational parameters. To initiate communication between the
two units the AV2 must be brought out of standby.
In order to prevent the direct adjustment of AV2 parameters
while on-screen display is operational, the AV2 front panel
display will show only
Integration of DVD5 and AV2 provides both with additional
facilities.

system component keys switched to the appropriate mode. To
switch both units to standby, regardless of the handset mode,
press and hold the handset
key.
9.2 Automatic Switching
The AV2 can be set to switch to an appropriate input when
specific types of disc are loaded into the DVD5. To enable
automatic switching the AV2 inputs must simply be labelled
appropriately. To auto switch the AV2 to a digital input when a
DVD or DTS-CD is inserted, label any ONE of the following inputs
DVD: OP1, OP2, CO1 or CO2.
To switch to an analogue input when a DVDA or CDDA is inserted,
either set the versatile inputs to “multi” mode or any analogue
input label to CD. If the versatile inputs are multi-channel and
another analogue input is labelled CD then AV2 will switch to the
versatile “multi” input.

14 Video Formats Explained
In the early days of domestic video and home theatre
the issue of different video formats and interfaces did
not really arise. There was only one way of connecting
a VCR to a TV - via the aerial cable. However the
growth in domestic high quality video, along with the
introduction of widescreen and non-CRT displays has
meant that video interface issues, once of concern
only to professionals, have become significant in
domestic systems.
The following few paragraphs provide an explanation
of some of the issues and technologies that impinge
on the DVD5, its installation and operation.
14.1 Video Display - Interlaced and Progressive Scan
Video is nothing more than a series of still pictures displayed
sequentially at such a rate that the brain perceives continuous
motion. A video signal comprises elements that describe the
colour and brightness of each individual display pixel and an
element that describes the necessary timing information required
to create an image. Each picture is “drawn”, pixel by pixel and
line by line, across and down the screen - again at a rate such
that the brain does not distinguish the segmented nature of the
information.
In conventional “interlaced” video, each still picture is drawn
half a screen at a time in two sections (or scans) constructed
from sets of alternate lines. This technique is used to reduce the
amount of information required for each frame. In “progressive
scan” video, rather than being constructed from two sections,
pictures are constructed in a single top to bottom scan. The result
is a significantly sharper, more detailed and more stable image.
14.2 Video Interface Formats
Table 6.4 (page 4) of this manual lists the video interface
formats supported by the DVD5 in order of preference defined
by the display quality potential of each. There are fundamental
technical reasons why alternative formats can provide different
levels of display quality and an explanation of these provides a
useful introduction to the techniques and technologies of video.
The formats are described, in reverse quality order, over the
following paragraphs.
14.2.1 Interlaced Composite Video (SCART, analogue)
The SCART (Syndicat des Constructeurs d’Appareils
Radiorécepteurs et Téléviseurs) connector first became familiar
on the introduction of high quality domestic video recorders.
These recorders were able to generate both “composite” and
“component” video signals and both, along with stereo analogue
audio, are carried by the SCART. Component video generally
describes those formats that carry the various elements of the
signal on separate cables - sometimes known as channels.
Composite video is a signal that encodes the three elements of a
moving image - colour, brightness and timing - in a single signal
carried by a single cable. Two different encoding formats are
common - NTSC generally in America and the Far East, and PAL
in Europe. Encoding the signal brings the advantages of single-
wire simplicity and convenience, but the necessary downstream
decoding produces unavoidable and visible artifacts. Composite
video thus offers the lowest display quality of the options
available and should be used if there is really no other option.
Very few contemporary displays or TVs will offer a composite
video input only .
14.2.2 S-Video (4 Pin mini-DIN, analogue)
The S-Video format offers the next higher quality video
connection. S-Video is a two channel based connection with the
colour and brightness information separated, and the timing
signal combined with the brightness signal. The separation
of colour and brightness reduces the need for downstream
processing to decode the signals and results in potentially a
sharper image.
14.2.3 YPbPr and RGB (SCART, analogue)
In addition to carrying a composite video signal the SCART
interface also carries a set of “RGB” or “YPbPr” video signals
selectable via the video setup menu. RGB denotes the
fundamental Red, Green and Blue components that define
a colour image. A timing signal is combined with the Green
signal. YPbPr is mathematically derived from RGB and denotes
brightness (Y) and two colour difference signals (Pb & Pr). The
video timing signal for the YPbPr format is combined with the
brightness signal. YPbPr carries the same information as RGB but
does so with reduced bandwidth demands. Both RGB and YPbPr
offer a further potential quality increase over S-Video by again
reducing the demands on downstream decoding. It is marginally
preferable to use RGB over YPbPr.
14.2.4 High Definition Progressive Scan YPbPr (3 x
BNC, analogue)
The first connection interface from which a Progressive Scan
signal is available. YPbPr Progressive Scan can be selected for
the BNC interface via the video setup menu.
14.2.5 High Definition Progressive Scan YPbPrHV (5x
BNC, analogue)
A second YPbPr/BNC interface provides the highest potential
video quality YPbPr signal. YPbPr HV is a five channel interface
with separate horizontal and vertical timing signals again
selectable via the video setup menu. Connecting to a display with
each signal element carried separately reduces the necessity for
downstream signal processing and potentially provides another
step up in video quality.
14.2.6 High Definition Progressive Scan RGB (3x BNC,
analogue)
A Progressive Scan RGB signal is also selectable via the video
setup OSD menu and available from the same three BNC
connectors described in paragraph 14.2.4. RGB is the native
video format of most displays and potentially provides better
quality than YPbPr thanks to reduced demands for downstream
signal processing. As with the SCART RGB interface, the video
timing signal is combined with Green signal.
RGB progressive scan output is disabled when replaying
Macrovision encoded material.

14.2.7 High Definition Progressive Scan RGBHV (5 x
BNC, analogue)
A second RGB/BNC interface provides the highest potential
video quality from an analogue signal. RGBHV is a five channel
interface with separate horizontal and vertical timing signals
again selectable via the video setup menu. Connecting to a
display with each signal element carried separately reduces to
a minimum the necessity for downstream signal processing and
potentially provides another step up in video quality. RGBHV is
also compatible with “VGA” style monitors.
RGB progressive scan output is disabled when replaying
Macrovision encoded material.
14.2.8 Progressive Scan DVI (DVI multi-pin, Digital)
The DVI interface provides the greatest potential video quality.
DVI is a direct digital connection for digital displays (LCD, Plasma
etc) and analogue displays with internal digital to analogue
converters. With DVI and a digital display, no downstream
decoding or signal conversion is required so the display quality
potentially matches that inherent in the source material. The
DVI output is HDCP (High-bandwidth Digital Content Protection)
encrypted and only compatible with HDCP capable displays (the
majority of computer DVI displays are not HDCP capable). HDMI
(High Definition Multimedia Interface) compatible displays can be
used with the DVD5 via an adaptor cable.

AV2
15 AV2 Basics and Quick Setup
Installation of the AV2 requires two setup routines to be carried out - input setup
and speaker setup. These routines configure the AV2 for the source equipment and
loudspeakers it is to be used with and specify some signal decoding options. Some
parameters depend on the state in which the AV2 was last switched off so setup
may be simplified if the AV2 is returned to its setup defaults. See Section 21 for
notes on restoring setup defaults.

AV2
16 AV2 Inputs and Interfaces
The AV2 has a total of ten audio inputs: six stereo
analogue and four digital. The analogue inputs are
connected through a combination of DIN and phono
sockets while two digital inputs are connected through
optical “TosLink” sockets and two through coaxial
phono sockets. A remote control RC5 input is also
fitted to enable remote control handset commands to
be relayed to the AV2. This feature provides enhanced
multi-room or concealed installation flexibility. The
RC5 input is selected during the Input Setup routine
described in Section 18. Your dealer or local Naim
Audio representative will be able to offer advice on its
use.
Analogue input sockets ONE and TWO are “versatile” sockets
that can be combined to enable the connection of source
components that already offer multi-channel outputs - DVD Audio
and Super Audio CD for example. When operating in combined
mode, eight or six input channels (available on the two DIN
sockets) are routed internally direct to the output volume control,
bypassing the internal signal decoding. Eight or six channel
combined mode is selected during the Input Setup routine
described in Section 18.
The input THREE socket also carries a stereo audio output signal.
If the AV2 is to be integrated into a conventional stereo audio
system this input/output socket should be connected either to
the system’s “tape monitor circuit” or in the case of a Naim
system to the appropriate preamplifier or power amplifier input
socket.
Integration of the AV2 with a conventional stereo audio
system may require a non-standard “reversed” connection cable. An
appropriate cable, identified by its yellow band, is included in the
AV2 document pack.
Each input socket and its appropriate connection is detailed in
Table 16.1. See the illustration in Section 22 for socket and pin
identification.
17 AV2 Outputs and Interfaces
The AV2 is fitted with line-level signal output sockets
for front left and right, centre, surround left and right,
extra rear left and right and sub-woofer channels.
The front, centre, surround and extra rear outputs are connected
through 4-pin DIN sockets and each of these should be routed
to appropriate Naim power amplifiers. The sub-woofer output
is connected through a single phono socket and should be
connected to either an active sub-woofer or a mono power
amplifier driving a passive sub-woofer. An alternative sub-woofer
output is available on the centre output socket.
The AV2 is also fitted with both analogue and digital audio
outputs. These outputs duplicate the selected input signal in
either the analogue or digital domain. No signal will be present
on the analogue output if a digital input is selected and similarly
no signal will be present on the digital output if an analogue
input is selected. The analogue outputs can be used to restore
the amplifier tape monitor outputs if these have been used as a
signal source for the AV2.
An interface connector fitted to the AV2 enables integration with
Naim DVD players. The interface is connected via a “telecoms”
style socket.On-screen display (OSD) of AV2 operational and
setup commands will be available if a DVD player is connected.
The interface socket should not be used for any other
application. Inappropriate use may cause damage to the AV2 or
other equipment to which the
socket is connected.
The multi-room interface socket
is a 9-pin RS232 type connector.
Multi-room interface functions
of the AV2 will depend upon
the capabilities of the multiroom system and controller
in use. Your local Naim Audio
representative will be able to
offer advice on multi-room
features.
Each output socket and its
appropriate connection is
detailed in table 16.1. See the
illustration in Section 22 for
socket and pin identification.

18 AV2 Detailed Setup
Once all the desired input and output connections are
made should the AV2 setup procedure be initiated.
Although the AV2 can be set up and controlled from
its front panel, many parameters are best set from
the primary listening and viewing position, so setup
from the NARCOM AV or NARCOM DV handset is
recommended. It is important however that the AV2
front panel is visible during setup because its display
provides feedback of control parameters. This is of
less importance if a DVD5 is connected as on-screen
display of setup parameters will then be available.
Flash remote handsets running Version 2 software can also
be used to control the AV2. For information on Flash software
updates please contact your local Naim Audio representative.
When initially powered up from the switch on the rear panel the
AV2 will, after a short delay as internal house-keeping is carried
out, be in Standby mode. Standby is indicated by an illuminated
Naim logo and a single dot indicator on the display. To wake
the AV2 press the handset
buttons). The AV2 will wake up in either the
default state, if it is previously unused, or in the state in which it
was last shut down.
There are two independent setup pages; each with a setup
routine to be executed: Input Setup and Speaker Setup. Input
Setup, which defines the type of source component connected
to each input, should be carried out first. Speaker Setup enables
various parameters and options for each speaker channel to be
set.
Some speaker setup parameters are dependent on the
selected AV2 input so setup may be simplified if the AV2 is
initially returned to its setup defaults. To restore the default values
separately in either setup “page” press and hold the handset disp
key while the AV2 is in the desired setup mode. The display flashes
once to confirm.
To restore the default values
simultaneously across both setup
pages press and hold the handset
disp key while the AV2 is in
normal mode. The mode button
will flash, three bars appear in the
display, and after a short delay the
AV2 will re-awake in input setup
mode. The factory default settings
are shown in Section 21.
The AV2 will drop out of
either setup mode after 5 minutes
if no keys or buttons are operated.
It may help during setup
to refer to the “quick setup”
diagrams in Section 15.
18.1 Input Setup Routine
The first AV2 setup page and routine defines the type of source
equipment connected to each input and enables a remote
control input function to be selected. To switch the AV2 into
Input Setup mode press the menu key followed by the
button).
The complete list of source component display options available
is as follows:

The following order of setup steps is arbitrary. It is possible to
move between setup steps by pressing
buttons).

and
options re-configure the DIN socket input connectors 1 and 2
to offer a combined set of analogue inputs routed direct to the
AV2 output volume control and output channels. Use the
control) to select the option
appropriate for the source component connected to the input(s).
Move to the next step by pressing
If you wish not to specify a specific source component for
any input, the right hand side of the display can either be left at
its default setting, or be set to “unused” by selecting ---. Inputs
set to --- will not appear for selection when in the AV2 is used in
operational mode.

Any three inputs can have a user-defined label of up to seven
characters stored. To define a user label, first select the input to
be named, say AN1-CO2, ensuring that it is set to its default label,
then press and hold either the handset OSD key or both the front
panel input and mode buttons. A line of seven dashes will appear in
the display. Using the front panel input and mode buttons and the
rotary control replace each dash with the desired letter or symbol.
Press and hold the handset disp key to clear any stored label. Exit
from user label definition by pressing and holding either the handset
OSD key or both the front panel input and mode buttons. On exit
the input’s default label will change to, say AN1-USR to denote that
a user label has been applied. The user label itself will display when
the input is selected.
Using inputs One and Two in combined mode enables the
connection of source components that may already offer multi-
channel outputs - DVD Audio and Super Audio CD for example.
When operating in combined mode the input channels available
on the two DIN sockets are routed, via the AV2 output volume
control, direct to the output connectors bypassing any internal signal
decoding processing.

18.1.5 Decode Specific Adjustments
The following four steps of the Input Setup routine enable the
adjustment of three parameters specific to Dolby Surround Pro
Logic II and one specific to DTS Neo:6 encoded programme
material. These parameters need not be changed from their
default settings during Input Setup but may be adjusted as
required when appropriate programme material is used.

18.2 Speaker Setup Routine
The Speaker Setup routine defines the presence and size of
the speakers connected to the main, centre, surround, extra
rear and sub-woofer outputs, their distance from the listening
position, and allows their relative volumes to be adjusted. To
switch the AV2 into Speaker Setup mode press the handset
Some parameters in the speaker setup routine are
interrelated. For example, if NO is specified for a specific speaker,
its setup options will be unavailable. Similarly if NO sub-woofer is
specified, only a default will be available for the main speakers.
The following order of setup steps is arbitrary. It is possible to
move between setup steps by pressing
buttons).
18.2.1 Main Left and Right Speakers - Size
The mode button indicator on the AV2 front panel will flash,
the display will show
on the left hand side and
refers to the main left and right channel
speakers and
(small) to their size. Pressing either
the 3
control) will prompt
the right hand side of the display to cycle though the
options. Select either option and move to the next step by
pressing 86
If the AV2 is being set up from its default state, the main left
and right speaker options will be limited to LG (large) until a sub-
woofer has been specified as present.
“Large” speakers are typically floor or stand mounted
products. “Small” speakers are typically those intended to be used
as part of a sub-woofer/satellite system. If LG (large) is selected, low
frequency effect signals only are routed to the sub-woofer channel.
If SM (small) is selected, both the low frequency effects and the
main channel low bass signals are routed to the sub-woofer.
18.2.2 Remaining Speakers - Size
Repeat the procedure for the Centre (
) channels each time selecting the
option with the 3
rotary control).
Move to the next step by pressing
Selecting a SM (small) centre channel speaker routes the
centre channel bass signal to the main left and right speakers or sub-
Selecting SM (small) surround speakers routes the surround
channel bass signal to the main left and right speakers. Selecting NO
In addition to size, the Extra Rear Speaker options include
those for quantity - 1SM (one small), 1LG (one large), 2SM (two
small) or 2LG (two large) The definition for “small” and “large”
speakers is the same as for surround speakers.
The facilities for “extra” rear channels on the AV2 ensures
compatibility with 7.1 encoded programme material.

frequency between the sub-woofer and any small speakers. Use
the 3

numerical value. Move to the next step by pressing
The frequency should be set appropriately for the sub-woofer
and speakers in use. Their specifications should provide guidance.
18.2.4 Left Main Speaker - Distance

on the left hand side and a
numerical distance value on the right hand side.
refers to the
left main speaker and the numerical value its distance from the
primary listening position. Use the 3

step by pressing
button).
18.2.5 Remaining Speakers - Distance
Repeat the procedure for the Centre (
) channels each time selecting
the appropriate distance value with the 3
control). Move to the next step by pressing
Defining the distance from the speakers to the listening
position adjusts only relative time delays and not volume levels.
The centre speaker should no further away from the listening
position than either main speaker.
If specific speakers have been previously defined as not
present their distance parameter will be unavailable.
18.2.6 Speaker Volume Level
The next eight steps of the Speaker Setup routine set the
relative volume levels of the channels. The first of these selects
and activates a test “noise” signal that enables the volume levels
to be adjusted by ear. Ensure that the AV2 is connected to the
necessary amplifiers and sub-woofer, that these are switched on,
and that the speakers are correctly connected.
The AV2 display will show
on the left hand side and either
on the right hand side. Pressing either the
control) will prompt the right hand side
of the display to cycle through
and move
to the next step by pressing
If the test signal is either too loud or too quiet the volume
can be adjusted with the volume up and down keys.
When using the test noise to adjust the volume level for each
speaker there are some issues that need to be considered if the
dynamic range of the AV2 is to be optimised.
The adjustment levels are relative values only and do not have any
effect on the loudness of the system for a given AV2 volume setting.
For example, if all the speaker channels had a setting of, say, -12
or if they all had a setting of, say, +6 the loudness of the system
would be the same at any setting of the master volume control. The
following procedure will ensure optimised dynamic range.

AV2
When using an active sub-woofer the adjustment level for the sub-
woofer output on the AV2 should be set somewhere between the
maximum and minimum settings needed for the other loudspeakers
in the system. The volume control on the sub-woofer itself should
then be adjusted to give the best results.
There is a similar requirement when setting the main left and right
speaker levels if the AV2 is integrated into a conventional stereo
system. The volume control on the preamplifier should be set to an
easily recalled position such that the adjustment levels for the main
left and right outputs of the AV2 are set somewhere between the
maximum and minimum settings needed for the other loudspeakers.
The volume control setting on the preamplifier will have to be set
every time the AV system is used - not forgetting to reset it for use
with music. For most Naim preamplifiers used with an AV2 the
volume control should be set to around 12 o’clock. The Naim NAIT
5 integrated amplifier and NAC 112x preamplifier have automatic
gain adjustment that takes effect when the AV input is selected, and
so the volume control does not have to be altered.
18.2.7 Main Left Speaker - Volume Level
Use the handset
keys initially to set a suitable
volume. The test signal should be heard through the Main Left
speaker. The AV2 display will show
on the left hand side and
a numerical value between

relative volume level. Use the 3
control) to select volume level initially of around zero.
Move to the next step by pressing
If the test signal is not heard through the left main speaker
the AV2, power amplifiers or speakers are not connected or set up
correctly.
18.2.8 Remaining Speakers - Volume Level.
Repeat the procedure for the Centre (
) channels each time
adjusting the volume using the 3
control) to be similar to the previous speaker. It is always
possible to return to and adjust the previous speaker by pressing
2
It may be helpful to cycle once or twice through all the
speakers before making any level adjustments.
If specific speakers have been previously defined as not
present they will not be included in the test.
If the test signal is not heard through the speaker designated
in the left hand side of the display at each stage, the AV2, power
amplifiers or speakers are not connected or setup correctly.
Take care when exiting speaker setup mode that adjustment
of the test signal has not left the overall volume set at an excessive
level.
This step completes the AV2 Speaker Setup routine. To exit from
Speaker Setup mode press the handset
button).
Exiting from setup mode stores the settings selected for each
parameter.
19 AV2 Operation
With inputs and outputs connected, and both setup
routines complete, the AV2 is ready for use. If a setup
parameter needs adjustment the setup pages are
always available from the remote handset or front
panel as described in Section 15 and 18. Remember
however that some speaker setup parameters
are subordinate to the selected input and decode
selection. For example, if an analogue input and
stereo direct mode are chosen, only the main left
and right speaker parameters will be available for
adjustment.
19.1 Input Selection and Volume Control
To select an input use the handset
key followed by one of
the
button).
The keypad numbers correspond to the input socket numbers.
The handset
6 can also be used to scroll through
the inputs. When a new input is selected the AV2 display will
sequentially show the input source (previously specified in the
Input Setup page) and the current decode mode settings. The
default display data is overall volume.
The AV2 may take a moment to display inputs and decode
modes when new inputs are selected as it locks on to, and
identifies, any signals. During this time the display will show three
flashing bars.
To adjust the overall volume use the
control).
19.2 Decode Modes - Selection and Availability
The signal decoding behaviour and options of the AV2 are
dependent on both the source programme material and in some
cases the speaker setup previously specified. With analogue,
and some digital programme material, decoding options are
user definable - although the results of processing for example,
music material with movie decoding mode are unpredictable. In
some cases however the AV2 will automatically identify encoded
material and only make available the appropriate decoding option
or options. The AV2 display and decode indicators together show
each decoding mode selected or imposed.
To select a decoding mode use the mode key (
button) followed by one of the
keypad numbers.
The keypad numbers correspond to decoding modes with lower
numbers selecting less complex modes (keypad
generally
selects direct or auto modes, keypad
selects stereo, etc). The handset
can
also be used to scroll through the available decode modes.
The selected decode option will flash in the display until the
AV2 has successfully “locked” to the signal before the display
reverts back to indicating volume. The AV2 will store the last
selected decode mode for each type of signal and for each input.
The decoding options and display for each type of programme
material, and the speaker channel schemes for each are detailed
in Tables 19.4 and 19.5.

AV2
19.3 Channel Schemes and Speakers
Channel schemes describe the speakers employed by each
decode mode. They are expressed by terms such as “5.1” or
“3/2.1” Taking 5.1 as an example, the “5” refers to the number
of conventional speaker channels and the “.1” refers to a subwoofer. In 3/2.1 the “3” refers to the number of front channels
employed (in this case, left, right and centre), the “2” refers to
the number of surround channels and the “.1” refers to a subwoofer. With appropriately encoded digital programme material
channel schemes are displayed by the AV2 when decode modes
and inputs are selected (if a signal is present).
The “direct” option available to analogue inputs routes
the signal directly to the output volume control, switching off and
bypassing any signal decoding. This is distinct from the “stereo”
decode option which digitises the incoming signal and uses internal
processing to control speaker channel routing.
Most decoding options and choices are self evident - a Dolby
Surround encoded movie signal (either digital or analogue) should
be decoded in Dolby Pro Logic Movie II mode for example.
DTS Neo:6, DTS-ES, and DTS Matrix can only be selected if
extra rear speakers are specified. If no such speakers are present
then DTS-ES Discrete encoded material will be decoded as DTS
3/2.1.

The continual
development of decoding
technologies means that your

some further or alternative
decode options. If this
appears to be the case please
visit www.naim-audio.com
and download the latest AV2
manual.
The channel scheme displayed by the AV2 for auto decoding
of digital material may depend on the specific scheme encoded
within the material. Schemes other than those shown in the table
above are possible.
Dolby Pro Logic and DTS Neo:6 decoding can be applied
to conventional analogue or digital stereo audio (CD for example).
Results however will be variable because effects, centre or sub-
woofer information is not usually encoded in conventional stereo
programme material in the first place. Conversely, DTS, Dolby
Surround or Dolby Digital Surround programme material decoded
to conventional stereo or mono will reproduce satisfactorily without
significant loss of programme information.

Decode Modes and Channel Schemes
19.6 Surround Encoding - Technology
Some feature films have carried the multi-channel sound
tracks necessary for “surround sound” since the 1950s. But
only since the mid 80’s has surround sound been available to
domestic consumers. The technology that first enabled four
channels of audio to be decoded from the stereo soundtrack of
consumer media such as video cassette is Dolby Surround Pro
Logic. Since Dolby Surround Pro Logic, and especially following
the introduction of digital products such as DVD, enhanced
encode and decode technologies have been introduced that
enable a greater number of higher quality channels of audio to
be encoded. With digital encoding techniques such as Dolby
Digital and DTS Surround, appropriately encoded feature films,
music and even computer games can be reproduced in fullbandwidth surround sound with up to eight audio channels (left,
right, centre, surround left, surround right, surround extra, lowfrequency effects).
The following few paragraphs provide a short description and
explanation of each decode technology and mode available
on the AV2. Further technical information can be found at
www.dolby.com and www.dtsonline.com
19.6.1 Dolby Surround Pro Logic
Dolby Surround Pro Logic is a matrix decoding process that
generates four output signals (left, right, centre, surround) from
a Dolby Surround encoded analogue stereo input signal. It is
built into virtually every home theatre audio system. The nature
of Pro Logic decoding constrains the single surround channel to
relatively narrow bandwidth.
19.6.2 Dolby Surround Pro Logic II
Dolby Surround Pro Logic II is an improved analogue matrix
technology that provides improved surround performance on
Dolby Surround encoded program material. While earlier surround
programme material is fully compatible with Pro Logic II,
appropriately encoded soundtracks can take full advantage of its
enhancements - which include separate full bandwidth left and
right surround channels. Pro Logic II also features two distinct
decoding options for “music” and “movie” programme material.
19.6.3 Dolby Digital
Dolby Digital is a fully digital decoding technology that provides
three full bandwidth front channels, two full bandwidth surround
channels, and one low-frequency effects channel - a channel
scheme known generically as “3/2.1” (or “5.1”). The encoding
technique for Dolby Digital, known as Dolby AC-3, has since
1995 been used on many Video Laser Discs and more recently
on DVD. Dolby AC-3 encoding can also be found on digital
television services. In addition to encoding audio for six channel
replay, Dolby AC-3 incorporates compression techniques that
ease audio data storage and transmission demands and can
enable, for example, a single DVD to carry a complete movie.
19.6.4 Dolby Digital 2/0
A variation of Dolby Digital 3/2.1 is Dolby Digital 2/0. Dolby
Digital 2/0 takes advantage of Dolby AC-3 data compression in
order to reduce the data storage demands of stereo programme
material. The “2/0” denotes the use of just two main audio
channels with no low frequency effects channel. Programme
AV2
The sub-woofer channel will only operate if Bass Mix is selected (see Section 19.7.2).
Operation of these channels will depend on the specific source material format.

material encoded for a “2.1” (two main channels with one subwoofer channel) channel scheme is also available and can be
handled within Dolby 2/0 decoding.
19.6.5 Dolby Digital Surround EX
The Dolby Digital Surround EX theatre system was co-developed
by Dolby Laboratories and Lucasfilm THX, and was first used
theatrically for the movie Star Wars: Episode I: The Phantom
Menace in 1999. The system uses 5.1-channel Dolby Digital
encoding but delivers an additional surround channel by mixing
its signal into the left surround and right surround channels
using matrix encoding. This additional channel is matrix decoded
upon playback and routed to one or more centre rear speaker.
Listeners with regular 5.1 channel Dolby Digital systems do
not lose the extra surround channel information; it is simply
reproduced by the left surround and right surround channels.
19.6.6 DTS Surround
DTS Surround is an alternative digital audio encoding format
that has become popular with feature film producers and can
therefore be found on many DVDs. The first feature film to
be DTS encoded was Jurassic Park in 1993. DTS Surround
provides a similar 3/2.1 channel scheme to Dolby Digital with the
encoding technology also providing data compression. The DTS
data compression ratio is lower than that in AC-3 however and it
is argued that DTS can provide better audio quality. The downside
of any quality improvement over AC-3 is however higher data
storage requirements.
19.6.7 DTS-ES Matrix
DTS-ES (Extended Surround) Matrix is an enhancement of DTS
Surround where a seventh channel is matrix encoded into the
left and right surround channels (matrix encoding is the class
of technology used in Dolby Surround Pro Logic). DTS-ES Matrix
provides a 6.1 channel scheme with the extra channel used to
reproduce effects located directly behind the listener.
19.6.8 DTS-ES Discrete 6.1
DTS-ES Discrete 6.1 differs from ES Matrix in providing a fully
independent seventh audio channel rather than it being matrix
encoded into two existing channels. This enhancement provides
opportunities for producers and engineers to generate surround
effects that would not be otherwise possible.
19.6.9 DTS Neo:6
DTS Neo:6 provides a decoding technique that enables legacy
analogue or digital stereo programme material to take advantage
of contemporary decoding technology and 6.1 channel schemes.
Material matrix encoded for four surround channels, or even
un-encoded stereo material can be processed by the DTS Neo:6
decoder to generate 3 main channels, 3 surround channels. The
low-frequency channel is generated by down-stream filtering.
19.7 Accessory Functions
The AV2 has six accessory functions accessible at all times from
the handset. The AV2 display will temporarily indicate selection
or de-selection of these functions.
19.7.1 Cinema EQ
Cinema EQ provides compensation for the over-emphasised high
frequency sound of some cinema soundtracks. It is selected or
disabled by pressing the menu key followed by the 2 key.
19.7.2 Bass Mix
The Bass Mix option routes main left and right loudspeaker
bass information to the sub-woofer. It is selected or disabled by
pressing the handset
Bass Mix is useful for encode formats that carry no specific
sub-woofer information.
19.7.3 Mute
The
key immediately reduces the volume to zero. A second
operation restores the volume to its previous level.
The volume can also be restored after a mute command
by turning the front panel volume control to zero and then up to a
normal listening level.
19.7.4 Display
The
key switches the AV2 display off. When switched off
the display will temporarily flash information when changes are
made. A second operation will restore the display.
The disp key is also used to restore AV2 setup defaults. See
Section 20.
19.7.5 Midnight
The
key compresses the signal and reduces the bass
content. It can help reduce disturbance to others from late night
listening.
Midnight is only available with Dolby Digital programme
material.

21.3 Restoring Defaults
When first woken from standby, an AV2 will hold either the
default setup values or those that were in use when it was last
shut-down. If the AV2 is to be set up for a new installation, and

DTS Digital Surround(tm) is a discrete 5.1 channel digital audio format available on CD, LD and DVD software which consequently cannot
be decoded and played back inside most CD, LD and DVD players. For this reason, when DTS-encoded software is played back through
the analogue outputs of the CD, LD or DVD players, excessive noise will be exhibited. To avoid possible damage to the audio system,
proper precautions should be taken by the consumer if the analogue outputs are connected directly to an amplification system. To enjoy
DTS Digital Surround(tm) playback, an external 5.1 channel DTS Digital Surround(tm) decoder such as the Naim Audio AV2 must be
connected to the digital output (S/PDIF, AES.EBU or TosLink) of the CD, LD or DVD player.
