In order to comply with current European safety regulations

it is essential that the Naim loudspeaker connectors supplied

with amplifiers and loudspeakers are used.

Do not under any circumstances allow anyone to modify your

Naim equipment without first checking with the factory, your

retailer, or your distributor. Unauthorised modifications will

invalidate your guarantee.

Equipment must not be exposed to dripping or splashing and

no objects filled with liquid, such as vases, should be placed

on the equipment.

For your own safety do not under any circumstances open

Naim equipment without first disconnecting it from the mains.

Warning: an apparatus with CL ASS I construction shall be

It is important for both safety and performance that

the standard cables supplied are not modified.

1.1 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 deposit may degrade the sound.

1.2 Loudspeaker Cables

Although any high quality loudspeaker cable is suitable, we

recommend that Naim loudspeaker cable is used. Naim

loudspeaker cable is directional and should be oriented so

that the printed arrow points towards the speakers. The

loudspeaker connectors supplied are designed to comply with

European safety legislation and must be used.

Contact your local retailer or distributor for further advice on

loudspeaker cables and connectors.

2 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.

2.1 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

or

and

2.2 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 retailer or at the factory by Naim itself.

2.3 Non-rewirable Mains Plugs

If a non-rewirable plug is cut from a mains lead (for whatever

purpose) the plug MUST 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.

2.4 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. A separate mains circuit (ideally with a

30 or 45 Amp rating) may reduce such distortion and 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.

Introduction

3 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.

3.1 Siting The Equipment

Some Naim equipment is extremely heavy. Check the weight of

the equipment prior to lifting and if necessary use more than

one person so that it can be moved safely. Ensure that your

equipment rack or table can easily support the weight and is

stable.

3.2 Switching On

Always use the switch on the product rather than a mains

outlet switch to switch the product on.

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

equipment is switched off.

3.3 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.

3.4 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. 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.

3.5 Lightning Precautions

Your Naim hi-fi system can be damaged by lightning 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.

3.6 Problems?

Consumer protection varies from country to country. In

most territories a retailer 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 retailer. Contact Naim Audio directly

for help and advice if necessary.

3.7 Service and Updates

It is essential that repairs and updates are only carried out by

an authorised Naim retailer 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 Customer Services:

Please quote the product serial number (found on its rear

panel) in all correspondence.

Introduction

n-Vi

4 Product Introduction and Contents

This manual covers installation and operation of the n-Vi all-in-one home theatre

system. With the n-Vi, combining DVD, home theatre and genuine high-end hi-fi

music reproduction is simple. The n-Vi includes everything you need in one box:

DVD and CD player, AV Processor, audio preamplifier, five channel audio power

amplifier and an optional DAB*/FM tuner. Just add speakers and a display.

The n-Vi is fundamentally straightforward in use, however its versatility and

comprehensive functionality mean that a little time spent reading will help ensure

problem-free setup and use.

The n-Vi should be installed on a dedicated equipment stand intended for the

purpose. Care should be taken to ensure that it is level. Do not switch on the n-Vi

until all input and output connections are made. Make sure you are familiar with

the safety warnings and general installation advice contained within the first part

of this manual.

Following this introduction, the manual is divided into the following sections.

Introduction

DAB radio broadcasts are not available in all territories.

5 Connections

Once the n-Vi is positioned on a rack or furniture

unit it can be connected to a mains supply. Use the

mains cable supplied. Do not switch on the n-Vi until

all audio, video and control connections have been

made.

The appropriate input and output connections will depend on

the type of system the n-Vi is to be used in. An Illustration of

the n-Vi input and output connections can be found on the page

opposite while a diagram illustrating the n-Vi integrated with an

existing stereo system can be found in Section 12.

It is important that high quality cable is used for signal and

speaker connections. Your local retailer or distributor will be

able to offer advice.

5.1 Signal Inputs

The n-Vi can accept three digital and four analogue audio

inputs for the connection of external source equipment. Two

of the digital inputs are connected via RCA-phono sockets and

one via an optical connector. Two of the analogue inputs are

connected via RCA-phono socket pairs and one via a 5-pin DIN

socket. One RCA-phono analogue input socket pair (Input A3)

is duplicated on the n-Vi front panel with a stereo 3.5mm jack

socket. This socket is intended for the temporary connection of

portable music players. Insertion of a plug into the front panel

jack socket will automatically switch the n-Vi to this input. If any

equipment is simultaneously connected to the rear panel A3

input sockets its audio signal will be mixed with the front panel

signal. Removal of the front panel input plug will automatically

switch the n-Vi to the previously selected input.

If the n-Vi has a DAB/FM Radio Upgrade fitted it will also have

an F-Type radio aerial input socket on the rear panel. Indoor

aerials can be used although best results are likely to be

obtained from roof aerials mounted as high as posssible. Use

high quality 75Ω aerial cable for connecting aerials.

Use of an aerial preamplifier may disturb the FM muting

operation of the tuner and may cause other problems. Such

preamplifiers should therefore only be used as a last resort.

An aerial combining unit may be used to combine signals from

separate DAB and FM aerials. Your local retailer or distributor

will be able to offer specific advice on local DAB and FM signal

reception.

For details of all signal input sockets see Diagram 5.7.

5.2 Control Inputs

The n-Vi provides control inputs that enable it to be integrated

with remote handset (RC5) signal repeaters and optionally

with multi-room equipment control systems. The RC5 signal is

connected through a single RCA-phono socket and the optional

multi-room control input connected through an RJ45 socket.

For details of all control input sockets see Diagram 5.7.

5.3 Video Outputs

The n-Vi 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 5.3 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. For details of all video

output sockets see Diagram 5.7.

5.4 Audio Outputs

The n-Vi provides one stereo analogue audio

output via a 5-pin DIN socket and one digital

audio output via a single RCA-phono socket.

These sockets enable the n-Vi to be connected

to an external audio preamplifier or alternative

multi-channel decoder respectively. In the

case of multi-channel programme material,

the signal present on the analogue output is

the front left and right channels. Analogue

programme material input to the n-Vi from an

external source is not available from the digital

output. The n-Vi also provides one analogue

subwoofer output via a single RCA-phono

socket. For details of all audio signal output

sockets see Diagram 5.7.

5.5 Speaker Outputs

The n-Vi provides five speaker output sockets each rated at

90 watts into 4Ω. The five speaker outputs are intended to

be connected to the front left, front right, centre, surround

left and surround right speakers. In order to comply with

European safety legislation speakers should be connected

using the supplied Naim Audio n-Vi speaker plugs only. Naim

Audio speaker cable is recommended although alternatives are

possible. Your local retailer or distributor will be able to offer

advice.

When connecting speakers ensure that each positive pin -

identified by a “

” mark on the side of the connector body - is

always inserted to the positive output sockets. Also ensure that

the connections at the speaker are connected with the same

polarity. For details of the speaker output sockets see Diagram

5.7.

5.6 Control Outputs

The n-Vi provides control outputs that enable it to be integrated
with remote handset signal (RC5) repeaters and optionally
with multi-room equipment control systems. The RC5 output is
connected via a single RCA-phono socket and the optional multi­room control output is connected via an RJ45 socket. For more
detail on connection to the control input sockets see Diagram

5.7.

Control and Setup

6 Control and Setup

Once all the input and output connections are made

the n-Vi can be set up. Although the n-Vi can be

set up and controlled from its front panel, many

parameters are best set from the listening position,

so use of the NARCOM DV handset is recommended.

When initially switched on from the rear panel, the n-Vi will,

after a short delay, enter standby mode. Standby is indicated

by an illuminated front panel

button. To wake the n-Vi

press the handset

key or front panel

button.

The n-Vi will wake in either the factory default state, if it is

previously unused, or in the state in which it was last shut

down. Once the n-Vi is switched on, the video display and any

other associated equipment should also be switched on.

The n-Vi can be returned to its factory default settings by

pressing and holding the handset clear key with no disc loaded.

6.1 The User Interface

The n-Vi can generally be operated from its front panel or

from the

remote handset in either

The term “channel scheme” describes the array of speakers in

use. The channel scheme operating at any time is linked to the

input signal, speaker setup and decode mode and is illustrated

on the n-Vi front panel display by an icon in the bottom right

hand corner (See Diagram 6.1.3). The icon changes as different

input signals and decode modes are selected (either manually

or automatically) or speaker setups are specified.

The icon represents a listening room with front left, centre,

front right, surround left, surround right and subwoofer

speakers. Each speaker element within the icon shows or hides

to denote presence in the speaker setup, grows or shrinks to

reflect “large” or “small” specification (see Paragraph 7.6.1),

The default value for lip sync is -10 which ensures correct

audio/video synchronisation on the DVI and BNC video outputs. For

correct synchronisation with interlaced video outputs (SCART and

S-Video) lip sync should be set to 0.

For 16:9 (widescreen) displays, non-widescreen programme

material will be accommodated by leaving a proportion of the

display either side of the picture unused. Widescreen material

on 4:3 (conventional) displays can be accommodated by

selecting either the

YPbPr is the appropriate selection for most programme

material. Video colour formats are explained in Section 10.

Three separate

sub-menus are available. One for

adjustment of the player’s

output, one

for adjustment of the player’s

YPbPr (YUV)

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.

YPbPr

adjustment covers luminance and saturation only.

The picture adjustments common to

outputs

are

Vertical Offset

,

and

YC Delay

.

The

adjustments enable the picture to be properly

centred in the display screen.

YC Delay

adjustment provides compensation for the timing

errors that can occur between the colour and brightness

elements of a video 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 DVI output.

No picture adjustment is available on the player’s SCART

and S-Video outputs.

night listening.

Midnight Mode is not available with analogue material.

The

key returns the n-Vi to standby mode. The standby

button only will remain illuminated.

9.5 Decode Modes - Selection and Availability

The signal decoding behaviour and options of the n-Vi are

dependent on both the source programme material and

the speaker setup. With 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 other cases however the n-Vi will

automatically identify encoded material and only make available

the appropriate decoding option or options. The n-Vi front panel

and on screen display will show each decoding mode selected

or imposed.

Stereo analogue inputs to the n-Vi are always routed direct to

the front left and right speaker outputs and cannot be decoded.

To select a decode mode use the handset

key or the

front panel

button. The n-Vi 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 9.5 and 9.6

9.6 Channel Schemes and Speakers

The term “channel scheme” describes the array of speakers in
use. The channel scheme operating at any time is linked to the
input signal, speaker setup and decode mode and is illustrated
on the n-Vi front panel display by an icon in the bottom right
hand corner (See Diagram 6.1.3). The icon changes as different
input signals and decode modes are selected (either manually or
automatically) or speaker setups are specified.

The icon represents a listening room with front left, centre,

front right, surround left, surround right and subwoofer

speakers. Each speaker element within the icon shows or hides

to denote presence in the speaker setup, grows or shrinks to

reflect “large” or “small” specification (see Paragraph 7.6.1),

or is filled or empty to denote its presence or absence in the

channel scheme.

9.7 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 full-

bandwidth surround sound with up to eight audio channels (left,

right, centre, surround left, surround right, surround extra, low-

frequency effects).

The following few paragraphs provide a short description

and explanation of encoding technologies. Further

technical information can be found at www.dolby.com and

www.dtsonline.com.

Dolby Surround Pro Logic is a matrix decoding process that

generates four output signals (left, right, centre, surround)

from a Dolby Surround encoded 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.

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 full bandwidth left and

right surround channels. Pro Logic II also features two distinct

decoding options for “music” and “movie” programme material.

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.

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 material encoded for a “2.1” (two main channels

with one subwoofer channel) scheme is also available and can

be handled within Dolby 2/0 decoding.

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.

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 n-Vi, its

installation and operation.

10.1 Interlaced and Progressive Scan Video

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.

10.2 Video Interface Formats

Table 5.3 lists the video interface formats supported by the

n-Vi 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.

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.

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.

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.

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.

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 10.2.4. 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 (and the screen will

appear blank) when replaying Macrovision encoded material.

n-Vi

Video Formats

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 n-Vi via an adaptor

cable.

11 DAB/FM Tuner

The optional n-Vi DAB/FM radio tuner module

provides access to DAB and FM radio broadcasts.

An appropriate aerial (or aerials) must be connected

to the aerial input before using the DAB/FM module.

See Section 5.7 for advice on aerials.

DAB radio broadcasts are not available in all territories.

The n-Vi treats DAB/FM radio as an internal digital audio source

therefore any appropriately encoded programme material can

be decoded for multi-channel reproduction.

DAB and FM setup and operational menus are only available

through the n-Vi Front Panel display.

With the DAB/FM module installed, clock and alarm functions

become available. These are set up within the Front Panel

Setup routine. See Sections 8.4 and 8.5.

A total of 30 stations, split between DAB and FM, can be stored

as presets.

11.1 DAB Menu and Operation

With the DAB/FM module installed the n-Vi input list will include

a DAB option. Use the handset

key to select this option.

If the DAB/FM module has not been used before the display

will request “scan for stations?” Use the handset

key to

commence the scan (or

key to decline). The n-Vi will

proceed to scan through the DAB radio band searching for

“live” stations. This may take a few minutes.

If the display does not request “scan for stations?” but the n-Vi

has been physically relocated it is advisable to re-scan anyway

by pressing the handset

key (while the DAB input is

selected) and selecting

Press the

key

to begin the scan. The scan may take a few minutes.

Always re-scan if the n-Vi has been moved to a different

location.

n-Vi

DAB/FM Tuner

When the station scan is complete the DAB menu provides

options to select either

tune mode

or

. In tune

mode stations are selected simply by scrolling through the full

list using the handset

(left) or

(right) keys.

In

stations previously stored as presets can be

selected either from the handset

keys, from the

(left) or

(right) keys or the

and

keys.

Some DAB stations do not broadcast at all times and may

be listed as unavailable.

To store a station as a preset select the station followed by

from the DAB menu. Input a preset number from

the handset

keys. Alternatively, presets 1-9 can be

assigned to a station at any time by pressing and holding

the desired handset

key number while the station is

selected. Any station (DAB or FM) previously assigned to that

number will be overwritten.

To delete a station preset select

from the DAB

menu and input the preset number from the handset

keys followed by the

key.

The DAB menu can be selected at any time by pressing the

handset menu key while the DAB input is selected.

With the DAB input selected the handset

(up) or

(down)

keys scroll through the display options of Preset Number,

Station Name, Scrolling Station Info, Programme Genre, Bit-

rate and Signal Strength.

11.2 FM Menu and Operation

With the DAB/FM module installed the n-Vi input list will include

an FM option. Use the handset

key to select this option.

With the FM input selected use the handset

key to enter

the FM menu.

The FM menu can be selected at any time by pressing the

handset menu key while the FM input is selected.

The FM menu provides options to select either

tune mode

or

. In tune mode stations are tuned by scrolling

through the FM band using the handset

(left) or

(right)

keys or entering a frequency using the

keys.

In

selection, storing and deletion of presets works

in exactly the same way as described above in Section 11.2

(DAB menu and Operation).

With the FM input selected the handset

(up) or

(down)

keys scroll through the display options of Preset Number (in

preset mode), Frequency (in tune mode), Station Name (RDS),

Scrolling Station Info (RDS), Programme Genre (RDS) and

Signal Strength.

System Connections

12 System Connections

Connection of the n-Vi in a stand-alone AV system

is straightforward. Each speaker output should

be connected to the appropriate speaker, the

subwoofer output connected to an active subwoofer

and a video display connected to the appropriate

video output. (See Diagram 5.7).

Integration of the n-Vi in an existing Naim system requires

a little more care and thought however. The diagram below

shows an n-Vi integrated in a system comprising a NAC252

preamplifier, Supercap power supply and NAP250 power

amplifier. The principles applied in this connection scheme are

similarly appropriate in any alternative systems but, if there

is any doubt, your local retailer or distributor will be able to

advise.

The preamplifier input must be set to unity gain mode. See

the preamplifier Owner’s Manual for further information.

Trouble-shooting

13 Trouble-shooting

The following list of typical problems and solutions

will help ensure trouble-free n-Vi installation and

use.

13.1 Video and Disc Playback

The n-Vi is set to YPbPr mode and the display is set to RGB

mode. See Section 7.4.1

The n-Vi is set to RGB mode and the display is set to YPbPr

mode. See Section 7.4.1

The n-Vi is converting from PAL to NTSC or NTSC to PAL. Set

n-Vi video output to auto or PAL/NTSC to match the format

recorded on the DVD in use. See Section 7.3.1

Handset is set to the wrong mode. Press the handset

key.

Handset batteries flat?

Fluorescent lights, reflective surfaces (rooms with lots of

windows) and LCD display panels can interfere with remote

control infrared signals. Switch off lights and display panels to

determine the cause. Re-positioning the n-Vi may be necessary

to cure the problem.

Handset has been inadvertently re-configured to work on a

different remote channel;

Press handset

key. While simultaneously holding the

and

keys press

key.

Press handset

key. While simultaneously holding the

and

keys press

key.

Video quality is poor using SCART.

SCART has two video signals, composite and YPbPr/RGB. The

display may be set to composite.

Progressive scan video is only available via the BNC or DVI

connections.

The n-Vi is set to NTSC and the display is set to PAL. See

Section 7.3.1

DVI to HDMI adapters are available from accessory retailers.

Optical DVI leads up to 500 metres long are available.

The display is not HDCP compliant. To meet DVD licensing

requirements the n-Vi DVI output is content protected using

HDCP. The display will need updating.

The picture disappears when “play” is selected.

The n-Vi video outputs are switched off. See Section 7.3.7

A Macrovision encoded disc is loaded and the display is

connected via RGB.

The image is not centred.

Check both the display and n-Vi alignment controls. See

Sections 77.3.4 and 7.4.2

The n-Vi remembers the last 10 discs played and the playback

position when they were ejected. To start from the beginning

load the disc, ensure the n-Vi is in stop mode then press

on the handset.

When in stop mode press the front panel

button.

The fan comes on.

When the unit becomes warm the fan switches on to regulate

the temperature. Ensure the unit is well ventilated and not

directly stacked on top of any other equipment.

13.2 Audio

The only formats that have native subwoofer information are

Dolby Digital and DTS 5.1 soundtracks. If you require sound

from the subwoofer enable bass mix from the on-screen or

front panel menu. See Section 7.5.2

Processing modes including bass mix cannot be applied to

analogue inputs. To generate subwoofer information from an

analogue source the subwoofer can either be connected at

line level to the n-Vi left and right output socket (line level)

or directly to the loudspeaker terminals (speaker level). The

subwoofer’s low pass filter will have to be set manually.

n-Vi

Trouble-shooting

Dolby Pro Logic II or Neo:6 surround mode is probably enabled.

Use the handset

key to select Stereo or auto.

Ensure test signal is switched on then select a speaker in the

level setup menu. See Sections 7.6.4 and 7.6.5

Ensure the master volume is not set to zero. Use the the

handset volume keys to adjust.

Player must be in stop mode with the disc input selected and

no disc loaded.

Test signal too quiet.

Use the handset volume keys to adjust the overall volume level

Ensure all speakers are correctly connected and defined in the

On Screen Setup.

Tip:

Press stop and listen for a very quiet hiss

from each speaker. You will need to be very near the speaker to

hear this. If a speaker has no hiss check the connections and

the On Screen Setup.

Ensure the n-Vi is not in stereo mode.

Check the disc has a 5.1 soundtrack (normally shown on the

back of the cover).

Press the audio button on the remote to cycle through the

available audio tracks. Some discs prohibit change of audio

format from the handset. In these cases the audio track must

be changed from the DVD menu. Access the DVD menu with

the handset

key.

Ensure centre and surround speakers are switched off in the On

Screen Setup. See Section 7.6.1

Check they are set to ‘large’ or ‘small’ and not to external. See

Section 7.6.1

Check the front panel display channel scheme icon. See

Diagram 6.1.3

when using an external amplifier.

Check the preamplifier or integrated amplifier AV input is set to

unity gain mode.

The front input can only be selected when a plug is inserted.

Audio from front panel input is mixed with input A3.

This is normal. The front input is a duplicate of input A3.

Either stop playback of the equipment attached to input A3 or

disconnect it. Having equipment connected to input A3 and the

front input simultaneously will not damage either the n-Vi or

source equipment.

Audio cuts-out at high levels.

The n-Vi will automatically protect its amplifier circuits if the

output exceeds safe levels. If this happens the sound will

momentarily be muted and a warning message displayed on the

front panel. If protection occurs at low volume levels contact

your local retailer or distributor for advice.
