2 Cables and Connections

Please do not modify the standard interconnect cables

supplied with your Naim equipment. This is important for

safety as well as performance. One end of each cable is

marked with a band to establish its correct orientation.

The band always marks the end that connects to the

signal source.

Loudspeaker leads are also very important. Naim

loudspeaker cable is correct for your system and your

dealer will make up leads to suit your equipment

installation. The leads should each be at least 3.5 metres

long and of equal length. The recommended maximum is

20 metres. Loudspeaker leads are, like interconnect leads,

directional, and should be connected so that the printed

arrow points towards the speakers. Using alternative

loudspeaker cable will degrade performance, and may even

damage your amplifier. An exception to these loudspeaker

cable constraints is the NAP 6-50 multi-room power

amplifier. The NAP 6-50 is designed to be tolerant of both

a wide variety of cable types, and cable runs well in excess

of 20m. The loudspeaker connectors supplied with all Naim

amplifiers and loudspeakers have been specifically

designed to make a robust mechanical connection. It is

essential that these are used in order to comply with

current European safety regulations.

All the plugs and sockets supplied with your Naim

equipment have been chosen because they make the best

possible connection for their purpose. A poor contact will

degrade the signal substantially and plugs and sockets

should look 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. Special

contact cleaners and contact enhancers should not be

used as they tend to deposit a film which is very difficult to

remove and may degrade the sound.

1 Equipment Installation

Normally your Naim equipment will have been installed by the dealer who sold it to you

even if you live outside their immediate vicinity. Your dealer is responsible for making

sure that the system sounds exactly as it should and information given here is not

intended to reduce this responsibility in any way.

Introduction

Naim Audio products are always conceived with performance as the

top priority and careful installation will help ensure that their full

potential is achieved. This manual begins with statutory safety

warnings and general installation tips for all Naim Audio products.

Product specific information begins in Section 6.

3 Getting Started

3.1 switching on and off

Source components and power supplies for cd players,

tuners, preamplifiers and crossovers should be switched

on before switching on the amplifier(s). Always switch the

amplifier(s) off and wait about a minute for the power

supply capacitors to discharge before connecting or

disconnecting any leads. Always use the power switch on

the product rather than a mains outlet switch.

3.2 running in

Your Naim equipment will take a considerable time to run

in before it performs at its best. The duration varies, but

under some conditions you will find that the sound

continues to improve for as much as five weeks. Better and

more consistent performance will be achieved if the system

is left switched on for long periods. It is worth

remembering however that all electronic equipment can be

damaged by lightning. Please read the warnings section.

Standards Declaration

3.3 mains supply

Where fused plugs are used 13 amp fuses should be fitted.

Fuses of a lower rating will fail after a period of use.

A hi-fi system usually shares a mains circuit with other

household equipment some of which can cause distortion

of the mains waveform. In some Naim equipment such

distortion can lead to a mechanical hum from the

transformers. The hum is not transmitted through the

speakers and has no effect on the performance of the

system but is purely local to the transformer itself. A

separate fused mains circuit (like that reserved for electric

cookers) may reduce transformer hum. Such a circuit

(ideally with a 30 or 45 Amp rating) will also have a lower

impedance, supply cleaner power, and consequently

improve system performance.

Do not wire voltage dependent resistors or noise

suppressors into mains plugs. They degrade the mains

supply and the sound.

3.4 siting the equipment

Power supplies and amplifiers should be located a

reasonable distance away from other equipment. This

separation will stop transformer radiation causing hum

audible from the loudspeakers. 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.

3.5 if you have a problem

Legal consumer protection varies from country to country.

In most territories a dealer must be prepared to take back

any Naim equipment he has sold you if he cannot make it

work to your satisfaction in your own home. A problem may

be due to a fault in any part of the system or its

installation so it is essential to make full use of your local

dealer’s diagnostic skills on site. Please contact your local

distributor, or Naim at the address in the back of this

manual, 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 guarantee

arrangements with your own dealer at the time of sale. We

are always available to offer help and advice.

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 made, tested or matched

specially for Naim and appropriate replacements are often

unobtainable from non-specialist sources.

4 Warnings

Naim equipment is designed to offer the finest sound

quality that can be achieved avoiding compromise

wherever possible. This can lead to circumstances that

may be unfamiliar. The material that follows contains

advice specifically related to Naim equipment as well as

more general warnings about the use of domestic audio

products. Please read it carefully.

The transformers in Naim power amplifiers and power

supplies may sometimes make a mechanical noise caused

by distortion of the mains waveform. Naim transformers are

large in size and have heavy gauge secondary windings

making them relatively sensitive to such distortion. A

separate mains circuit for your hi-fi system may reduce the

effect while also giving an overall improvement in sound

quality. It may be necessary however to take account of

mechanical transformer noise when siting your equipment.

IMPORTANT

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 dealer, or your distributor. Unauthorised modifications will invalidate your guarantee.

For your own safety do not under any circumstances open Naim equipment without first disconnecting the mains.

The following label is attached to all mains powered equipment:

WARNING

THIS APPARATUS

MUST BE EARTHED

Introduction

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. If there is a known

problem in your locality it is advisable to arrange for a

home demonstration before purchase to find out if Naim

equipment is likely to be affected. 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.

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

amplifiers are particularly at risk and should be turned off

when there is risk of lightning strike. For complete

protection all mains plugs and any aerial cables should be

disconnected when not in use.

Equipment must not be exposed to dripping or splashing

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

placed on the equipment.

Use of non-standard speaker cables or interconnects may

invalidate your guarantee.

5 Connection

5.1 mains lead

As the colours of the wires in the mains lead of this

apparatus may not correspond with the coloured markings

identifying the terminals in your plug proceed as follows:

The wire which is coloured GREEN-AND-YELLOW must be

connected to the terminal in the plug which is marked by

the letter E or by the safety earth symbol or coloured green

or green-and-yellow.

The wire which is coloured BLUE must be connected to the

terminal in the plug which is marked with the letter N or

coloured black.

The wire which is coloured BROWN must be connected to

the terminal in the plug which is marked with the letter L or

coloured red.

5.2 non-rewireable mains plugs

If a non-rewireable 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.

5.3 fuse carrier

Should the plug fuse carrier be damaged or lost, the

correct replacement must be obtained from your dealer, or

from Naim Audio direct. Do not use the plug until the fuse

carrier is replaced.

5.4 plug fuses

Replace only with ASTA or BS 1362 approved fuses.

NOTE

This equipment has been tested and found to comply with the relevant EMC and Safety Standards, and, where applicable, also complies with the limits for a class B digital device, pursuant to Part 15 of the FCC Rules.

These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and the receiver.

• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

• Consult your Naim dealer or an experienced radio/TV technician for help.

6 Introduction and Positioning

Naim loudspeakers are precision acoustic instruments that will only achieve optimal

performance if installed and set up carefully. Please read these instructions before

unpacking, installing and using the loudspeakers. Please also retain the packaging for

future use.

The performance of any loudspeaker will be influenced by

the room in which it is located and even small changes of

loudspeaker position can significantly influence the sound.

Choose a site where the loudspeakers can be located

between 1.2m and 4m apart (4ft and 13ft), clear of room

corners, and where each loudspeaker is between 10cm and

45cm (4” and 18”) away from a solid rear wall. The

distance between the speakers and the rear wall is the

aspect of positioning most likely to require adjustment as

you become familiar with the characteristics of the

loudspeakers in your room.

Loudspeakers, like many hi-fi components, will take time to

stabilise and “run-in” and can be expected to improve with

use even over a period of weeks. For this reason it is

prudent not to finalise loudspeaker positioning until the

system has been operating for at least one week.

6.1 Unpacking SL2

To minimise the risk of accident and damage, SL2

components should be removed from the packaging one

speaker at a time and in the

following order. Components

referred to in the following

paragraphs can be identified

through diagram 6.4.

Remove the central packing

piece and Tweeter Suspension

Assembly. Separate the two

and place the Tweeter

Suspension Assembly to one

side.

Remove the card shield

containing the Grille. Place the

Grille to one side. Also remove

the card packing piece that

protects the curved top of the

Upper Cabinet.

Carefully lift the Upper

Cabinet out of the carton and

place it to one side. Take care

not to damage either the drive

unit or the aluminium plate on

the underside of the cabinet.

Now lift the Lower Cabinet, together with its foam end-

caps out of the carton. Stand it on the floor, plinth

lowermost, and remove the top foam end-cap. Turn the

cabinet upside down being careful not to damage the

aluminium plate. Finally remove the sprung foam end-cap

by pulling its sides outward and lifting it over the plinth.

6.2 Assembling and Installing SL2

Stage 1

With each Lower Cabinet upside down the floor spikes can

be fitted. Screw a spike and lock-nut into each threaded

hole in the plinth. If the loudspeakers are to stand on a

thick carpet, leave a generous length of spike protruding

past the lock-nut. If they are to stand on thinly carpeted or

plain floor, the spike length should be reduced. In either

case, best results will be achieved when the spike length is

set to the minimum required for the spike lock-nuts to sit

just above the carpet pile.

intended to be slightly loose.

Stage 2

Take each Tweeter Suspension Assembly in turn and offer

it up to the Tweeter Mounting Points on the rear of each

Plinth. Attach it using the bolts and allen key supplied. The

Tweeter Suspension Assembly should be fixed as close to

vertical as possible. Use the back of the Lower Cabinet as

a guide.

SL2

Now move each Lower Cabinet with the Tweeter Suspension

Assembly attached into the appropriate position. Take care

not to place them so close to the wall that the rear spikes

foul any carpet gripper that may be fitted. Also leave some

space for final adjustment of the Tweeter Suspension

Assembly and for the connecting cables.

Adjust the spikes so that the cabinets are upright (a small

spirit level will help) and do not rock. Tighten the lock-nuts

with an appropriate spanner.

Check again, once the lock-

nuts are tightened, that the

cabinets do not rock on the

spikes.

Note: With thick carpet and

underlay it can be difficult to

ensure that the spikes are

resting on the floor. Small slits

cut into the carpet once the

loudspeaker position is

finalised will help.

Stage 3

The pack containing this

manual also contains Cabinet

Interface Pins and Cabinet

Spacers. Fit a Pin and a

Spacer to the three holes in

the aluminium top surface of

each Lower Cabinet. There

are two holes at the front and

one at the back. Spare Pins

and Spacers are included in

the pack. The Pins should be

a loose fit in the holes. See

Diagram 6.4

Now take each Upper Cabinet

in turn and carefully lower it

onto the appropriate Lower

Cabinet locating the Pins in

the corresponding holes on its

underside. At the same time

as each Upper Cabinet is

lowered onto each Lower

Cabinet, the tweeters must be

inserted through the apertures

of the Upper Cabinets. The

loose fit of the Pins allows

some adjustment of the

alignment of the two cabinets.

SL2

Assembling and Installing SL2 (continued)

It is vitally important for correct operation of SL2 that the

Upper Cabinets are located properly on the Lower

Cabinets, that the Pins are in place and that the two

cabinets only touch via the spacers.

The alignment of the Tweeter within the Upper Cabinets can

be adjusted via either the two bolts connecting the Tweeter

Suspension Assembly to the Plinth or the four screws that

attach the Tweeter Adjustment Panel around the front face

of the Tweeter. If the four adjustment panel bolts are

loosened they should be re-tightened as securely as

possible. As well as being adjusted to sit centrally when

viewed from the front, and flush with the front panel, the

Tweeter must oscillate freely without touching any part of

either cabinet.

Finally fit a Grille to each SL2 by aligning it with the top of

the Lower Cabinet before pushing it gently against the

fixing tape on the Upper Cabinet. The lower edge of the

Grille should not touch the Lower Cabinet. The card

spacing jig packed with this manual can be used to support

the bottom edge of the Grille as it is fitted. Seen from the

side, the Grille should continue the curved form of the

front of the Lower Cabinet.

6.6 Connection

If the loudspeakers are to be used with Naim amplification,

use only Naim loudspeaker cable. Cable lengths to both

loudspeakers should be equal and be between 3.5 metres

and 20 metres (11.5ft and 66ft). Your local retailer will be

able to make up cables of the appropriate length.

If the SL2 is to be used in an active system, speaker

cables with their custom Naim plugs should be connected

to the appropriate input sockets on the back of the

Tweeter Suspension Arm (HF) and Upper Cabinet (LF).

Ensure that each positive plug - identified by a rib on the

side of the cable and a tag marked “pos” on the side of

the connector body - is inserted to the red input sockets.

If the SL2 is to be used in a passive system, the Passive

Crossover Units must be mounted to the back of each

Lower Cabinet. Screws and decoupling grommets are

supplied in the pack that contains the passive crossovers.

Tighten the screws so that the screw heads just touch the

decoupling grommets without compressing them.

The output cables from the Passive Crossover Units must

be connected to the input sockets on the back of the

speaker, the longer cable to the sockets on the back of

each Tweeter Suspension Assembly and the shorter cable

to the sockets on each Upper Cabinet. The cables should

be dressed such that they do not touch any other SL2

component and such that the output plugs align naturally

with input sockets. Stress in the cables will interfere with

the decoupling between SL2 components.

Finally the amplifier output speaker cables, with their

custom Naim plugs, should be connected to the input

sockets on the back of the Passive Crossover Units.

Ensure that each positive plug - identified by a rib on the

side of the cable and a tag marked “pos” on the side of

the connector body - is inserted to the red input sockets.

The performance of any loudspeaker will be influenced by

the room in which it is located and even small changes of

loudspeaker position can significantly influence the sound.

Choose a site where the loudspeakers can be located

between 1.2m and 4m apart (4ft and 13ft), clear of room

corners, and where each loudspeaker is between 10cm and

45cm (4” and 18”) away from a solid rear wall. The

distance between the speakers and the rear wall is the

aspect of positioning most likely to require adjustment as

you become familiar with the characteristics of the

loudspeakers in your room.

Loudspeakers, like many hi-fi components, will take time to

stabilise and “run-in” and can be expected to improve with

use even over a period of weeks. For this reason it is

prudent not to finalise loudspeaker positioning until the

system has been operating for at least one week.

7.1 Installation

Stage 1

Each allæ and Intro 2 loudspeaker comprises two separate

cabinet components, the Upper Cabinet, containing the

bass/mid driver, and the Lower Cabinet, containing the

tweeter. These Components can be identified through

diagram 7.3.

To begin installation, first fit the floor spikes and lock-nuts

to the base of each Lower Cabinet. The cabinets can

safely be turned upside-down to aid fitting the spikes. If

the loudspeakers are to stand on a thick carpet, leave a

generous length of spike protruding past the lock-nut. If

they are to stand on thinly carpeted or plain floor, the spike

length should be reduced. In either case, best results will

be achieved when the spike length is set to the minimum

required for the spike lock-nuts to sit just above the carpet

pile.

Note: The metal bar across the rear underside of the allæ

that attaches the Lower Cabinet to the Plinth is intended

to be slightly loose.

With the floor spikes fitted, each Lower Cabinet can be

placed in the appropriate position. Take care not to place

the loudspeakers so close to the wall that the rear spikes

foul any carpet gripper that may be fitted. With the

allæ, Intro 2

cabinets in position, adjust the spikes so that the cabinets

are upright (a small spirit level will help) and do not rock.

Tighten the lock-nuts with an appropriate spanner. Check

again, once the lock-nuts are tightened, that the cabinets

do not rock on the spikes.

Note: With thick carpet and underlay it can be difficult to

ensure that the spikes are resting on the floor. Small slits

cut into the carpet once the loudspeaker position is

finalised will help.

stage 2 (allæ)

The pack containing this manual also contains six small

Precision Interface Pins (PIPS). Fit three PIPS in the three

holes in the top surface of each Lower Cabinet. There are

two holes at the front and one at the back. The PIPS

should be a loose fit in the holes.

Take each Upper Cabinet in turn and carefully lower it onto

the appropriate Lower Cabinet locating the PIPS in the

corresponding holes on its underside. The loose fit of the

PIPS allows some adjustment of the alignment of the two

cabinets.

stage 2 (Intro 2)

The pack containing this manual also contains six small

Precision Interface Pins (PIPS). Fit three PIPS in the three

holes in the top surface of each Lower Cabinet. There are

two holes at the front and one at the back. The PIPS

should be a loose fit in the holes.

Take each Upper Cabinet in turn and carefully lower it onto

the appropriate Lower Cabinet locating the PIPS in the

corresponding holes on its underside. The loose fit of the

PIPS allows some adjustment of the alignment of the two

cabinets.

As each Upper Cabinet is lowered onto the PIPS connect

the two cables fitted with sockets to connection pins visible

through the hole in the top of Lower Cabinet. Ensure that

the connections are made with the red socket connected

to the left hand pin.

stage 3

Remove the protective tape from the high frequency drivers

mounted in the front of each Lower Cabinet. Fit the grilles

to the front of each Upper Cabinet by locating the grille

studs in the corresponding holes in the cabinet.

output speaker cables with their custom Naim plugs to the

input sockets on the back of the passive crossover units.

Ensure that each positive plug - identified by a rib on the

side of the cable and a tag marked “pos” on the side of

the connector body - is inserted to the red input sockets.

loudspeaker cables with custom Naim plugs directly to the

appropriate power amplifier.

Intro 2

Connect the loudspeaker cables with their custom Naim

plugs to the input sockets located on the rear of the Lower

Cabinet. Ensure that each positive plug - identified by a rib

on the side of the cable and a tag marked “pos” on the

side of the connector body - is inserted to the red input

sockets.

7.3 Speaker Components

The performance of any loudspeaker will be influenced by

the room in which it is located and even small changes of

loudspeaker position can significantly influence the sound.

Alignment with the listening position and proximity to room

boundaries will in particular influence the subjective

performance. The position of a centre channel loudspeaker

tends to be influenced by the type and location of the

associated video screen. However, the influence of the

room boundaries and alignment to the listening position

should still be taken into account.

The axent and axess are designed to reproduce full

bandwidth, full power signals and are intended to be

positioned centrally just below the screen. If the location of

the loudspeaker results in too much bass some adjustment

of low frequency equalisation via the AV processor may be

necessary.

Best results from axent and axess are likely to be gained if

they are directly coupled to the floor via a rigid, spiked

stand. Both speakers are equipped with spike location pads

on the underside to help enable such mounting. If however

the screen stand is also to carry the speaker it is advisable

to at least decouple the screen, perhaps with compliant

pads, so that vibration from the speaker does not disturb

the picture.

The axent and axess are magnetically shielded. However,

the extreme sensitivity of some CRT tubes to low levels of

magnetic flux may mean that, in rare cases, the shielding

may not be sufficient. Should your screen suffer picture

distortion caused by the proximity of a centre speaker

contact your dealer or installer for advice.

8 Introduction and Positioning

Naim loudspeakers are precision acoustic instruments that will only achieve optimal

performance if installed and set up carefully. Please read these instructions before

installing and using the loudspeakers. Please also retain the packaging for future use.

8.1 Connection

If the axent or axess are to be used with Naim

amplification, use only Naim loudspeaker cable. Cable

length should be between 3.5 metres and 20 metres

(11.5ft and 66ft). Your local retailer will be able to make up

cables of the appropriate length.

Connect the loudspeaker cables with their custom Naim

plugs to the input sockets located on the rear of the

enclosure. Ensure that the positive plug - identified by a rib

on the side of the cable and a tag marked “pos” on the

side of the connector body - is inserted to the red input

socket.

8.2 Tweeter Adjustment

The tweeter is mounted on an adjustable suspension plate.

It is important both that the tweeter “bounces” freely on

the plate and that it is held in line with the front panel of

the enclosure.

If the tweeter does not bounce or it is not held in the

correct position (ie the plate appears bent), the plate can

be adjusted. Carefully remove, one at a time, the

appropriate fixing screws and gently bend the appropriate

arm or arms of the plate to correct the bend. Replace the

screws, tightened as lightly as possible to ensure security,

and re-test the “bounce”. Repeat the exercise if necessary.

The diagram below illustrates the tweeter suspension plate

correctly and incorrectly adjusted.
