Selecting fine audio equipment such as the unit you’ve just purchased is only the start of your musical enjoyment. Now it’s time to consider how you can maximize the fun and excitement your equipment offers. This manufacturer and the Electronic Industries Association’s Consumer Electronics Group want you to get the most out of your equipment by playing it at a safe level. One that lets the sound come through loud and clear without annoying blaring or distortion-and, most importantly, without affecting your sensitive hearing.

Sound can be deceiving. Over time your hearing “comfort level” adapts to higher volumes of sound. So what sounds “normal” can actually be loud and harmful to your hearing. Guard against this by setting your equipment at a safe level BEFORE your hearing adapts.

To establish a safe level:

Start your volume control at a low setting.

Slowly increase the sound until you can hear it comfortably and clearly, and without distortion.

Once you have established a comfortable sound level:

• Set the dial and leave it there.

Taking a minute to do this now will help to prevent hearing damage or loss in the future. After all, we want you listening for a lifetime.

We Want You Listening For A Lifetime

Used wisely, your new sound equipment will provide a lifetime of fun and enjoyment. Since hearing damage from loud noise is often undetectable until it is too late, this manufacturer and the Electronic Industries Association’s Consumer Electronics Group recommend you avoid prolonged exposure to excessive noise. This list of sound levels is included for your protection.

Decibel

Level Example

30 Quiet library, soft whispers

40 Living room, refrigerator, bedroom away from traffic

50 Light traffic, normal conversation, quiet office

60 Air conditioner at 20 feet, sewing machine

70 Vacuum cleaner, hair dryer, noisy restaurant

80Average city traffic, garbage disposals, alarm clock at two feet.

THE FOLLOWING NOISES CAN BE DANGEROUS UNDER CONSTANT EXPOSURE

90 Subway, motorcycle, truck traffic, lawn mower

100 Garbage truck, chain saw, pneumatic drill

120 Rock band concert in front of speakers, thunderclap

140 Gunshot blast, jet plane

180 Rocket launching pad

Before you start

The nominal impedance of this speaker system is 6 Ω.

Connect the speaker system to an amplifier with a load impedance ranging from 4 Ω to 16 Ω (a model with “4 Ω to 16 Ω” displayed on the speaker output terminals).

In order to prevent damage to the speaker system resulting from input overload, please observe the following precautions:

Do not supply power to the speaker system in excess of the maximum permissible input.

When using a graphic equalizer to emphasize loud sounds in the high-frequency range, do not use excessive amplifier volume.

Do not try to force a low-powered amplifier to produce loud volumes of sound (the amplifier’s harmonic distortion will be increased, and you may damage the speaker).

Caution: installation

When placing this unit, ensure that it is firmly secured and avoid areas where it may be likely to fall and cause injury in the event of a natural disaster (such as an earthquake).

Do not attach these speakers to the wall or ceiling. They may fall off and cause injury.

Do not install your speakers overhead on the ceiling or wall. If improperly attached, the speaker grille can fall and cause damage or personal injury.

Switch off and unplug your AV equipment and consult the instructions when connecting up components. Make sure you use the correct connecting cables.

Caution: in use

Do not place the speaker on an unstable surface. It could present a hazard if it falls, as well as damaging the equipment.

Do not use the speaker to output distorted sound for long periods of times. This can result in a fire hazard.

Do not sit or stand on the speaker, or let children play on the speaker.

Do not put large or heavy objects on top of the speaker.

Do not place magnetic objects such as screwdrivers or iron parts near the tweeter or midrange. Since the speakers use strong magnets, the objects may be attracted, causing injury or damaging the diaphragm.

CAUTION

These speaker terminals carry HAZARDOUS LIVE voltage. To prevent the risk of electric shock when connecting or disconnecting the speaker cables, disconnect the power cord before touching any uninsulated parts.

WARNING: Handling the cord on this product or cords associated with accessories sold with the product will expose you to chemicals listed on proposition 65 known to the State of California and other governmental entities to cause cancer and birth defect or other reproductive harm.

About the EX series

The EX series, incorporating the abundant technological know-how behind Pioneer's flagship TAD speaker series, was developed with the goal of creating the ultimate speaker possible in its price range.

The design and production of the EX series result from an international effort that represents the finest in Pioneer's speaker technology.

Technology behind the S-3EX

CST

The core driver of the system is the Coherent Source Transducer (CST), which draws on the technology used in TAD. The tweeter diaphragm is mounted concentrically within the apex of the midrange cone and provides a point source of sound from 400 Hz to 100 kHz. The CST ensures a perfect spectral balance between the direct and reflected sounds that arrive at the listener's ears, providing a more consistent sound throughout the listening room and improved imaging capability.

Ceramic Graphite Diaphragm

The CST's tweeter features a ceramic graphite diaphragm that provides top-level strength and dampening characteristics that are practically unrivaled by any other available materials currently used in high-end audio speaker systems. Ceramic graphite's lightness and exceptional strength combine to create speakers whose diaphragm resonance can be pushed far beyond their audible range.

Inner Loss

 

Magnesium Alloy Diaphragm

The CST's midrange features a magnesium alloy diaphragm whose characteristic lightness and high inner loss provide excellent transience and minimal coloration of midrange sounds.

Bass Drivers

The bass driver pictured below serves as the foundation of the S- 3EX speaker system. The driver's strength is the result of the Aramid/Carbon composite material, originally created during the development of the S-1EX, that is used in its diaphragm. Pioneer's exclusive LDMC magnetic circuit technology has been incorporated in order to preserve linearity from low to high output levels and minimize distortion.

Bass Enclosure Construction

The unique form of the S-3EX is based upon logical necessity. In order to synchronize the arrival time of sound from the CST and the two bass drivers, each driver is mounted upon a baffle that serves to create a highly delicate curve known as the "precision curve" (see illustration below). Made of up to 100 mm thick MDF (Medium Density Fiberboard), this baffle is, moreover, strong enough to contain the force of the drivers. Additionally, the bass port has been carved out of an extremely thick block of MDF, resulting in the reduction of wind noise for clear, deep bass.

Crossover Networks

The crossover networks use only the finest components. Air cored coils, noninductive resistors, and film capacitors in the signal path are all carefully chosen and optimized for the CST driver to provide the greatest transparency to the signal. The bass drivers use silicon steel plate core inductors that minimize distortion and loss during energy transfer. All components are connected directly to their respective wiring materials, instead of a printed circuit-board, allowing for minimal loss and maximum performance.

Collaboration with Air Studios

Since its establishment by George Martin in 1969, London, England's Air Studios has earned unequivocal respect from scores of artists who recognize it as the world's premier recording studio. The Air Studios seal that was awarded to the S-3EX indicates that these speakers are capable of producing the highquality sound demanded by the world's top-class sound creators.

Installation and Placement

How to install

This speaker system is supported by three points (the front two legs, and the back spike located between the back two legs).

Front

Nut (for spike)

Cabinet base

Back

Back spike

 

Legs

1 Choose the location for speaker placement then put the spike bases on the floor.

2Place the speaker on top of the spike bases.

3If either the left or right back legs touches the ground before the back spike, resulting in the speaker not resting flat on its placed surface, adjust the back spike so it extends to the ground before either of the back legs.

4Place the included mounting pads underneath the back legs to keep the speaker stable.

Choose the most appropriate thickness of mounting pad from the several types included.

Mounting the Fall-Prevention Fastener

Using the included screw, tightly secure the metal catch to the backside of the speaker.

Pass a commercially-available reinforced string through the metal catch to securely support the speaker to the wall. Be sure that the wall to which you fasten the speaker is strong enough to support the weight of the speaker. After fastening the speaker, make sure that it does not fall over.

The speaker can incur damage in the event of a fall.

Do not attach the metal catch directly to the wall. It should only be used in conjunction with reinforced string to prevent the speaker from falling.

Metal catch

Sufficiently thick cord

Backside of speaker

Pass two reinforced strings through the metal catch, and fasten the speaker to the wall as shown above.

Do not place the speaker where it will be in direct sunlight, and avoid positioning it near heaters and air conditioners. Doing so may cause warping and discoloration of the speaker cabinet and damage to the speaker.

Pioneer assumes no liability whatsoever for damages resulting from assembly, improper mounting, insufficient reinforcement, misuse of the product, acts of nature, etc.

Mounting pad

Do not place the speaker on an unstable surface. It could present a hazard if it falls, as well as damaging the equipment.

As a precautionary measure, be sure to not place the unit anywhere where it might fall on a sleeping individual in the event of an earthquake.

As this unit weighs some 48 kg, it is very dangerous to try and set the spike nut while tilting the speaker. Be sure to place the unit on a soft area (such as a blanket) so that it does not damage the floor, and carry out the installation with at least two people.

Connections

Connecting to an amplifier

This speaker does not include speaker cables used for connecting to an amplifier. Take the following factors into consideration when choosing speaker cables so that you can get the most from your speaker system:

Use heavy-gauge speaker cable if possible, and keep the cables to the minimum necessary length.

If the length of cable required for left and right speakers differs, use cables of the same length, matched to the longer distance.

Cables have differing characteristics. Keep this in mind when using any cable.

Select cables with as little resistance as possible, and make sure the cables to the speaker terminals and amp are firm and secure.

Connecting the cables

1Switch off the power to your amplifier.

2Connect the speaker cables to the input terminals (lower) on the back of the speaker. For input terminal polarity, red is positive (+) and black is negative (–).

3Connect the other ends of the cables to the amp's speaker output terminals (for more details, refer to your amp owner's manual).

Short bar connectors

Red terminal

(+) Black terminal

(–)

Grasp the cap knobs on the lower input terminals and rotate them to the left (counter-clockwise), insert the speaker cable wires into the holes in the terminal posts, then tighten the knobs to secure the short bar as well as the wires.

You can also connect the speaker’s terminals with a banana plug. When using a banana plug, be sure to remove the cap at the tip of the input terminal.

After connecting the plugs, pull lightly on the cables to make sure that the ends of the cables are securely connected to the terminals. Poor connections can create noise and interruptions in the sound.

If the cables' wires happen to be pushed out of the terminals, allowing the wires to come into contact with each other, it places an excessive additional load on the amp. This may cause the amp to stop functioning, and may even damage the amp.

When using a set of speakers connected to an amplifier, you won't be able to obtain the normal stereo effect if the polarity of one of the speakers (left or right) is reversed.

Bi-Wire Connections

In a bi-wiring connection, you independently plug in the speaker systems running from the amp to their respective highand lowfrequency plugs. This results in the CST driver and bass drivers being independently connected directly to the amplifier, offering you the freedom to optimize the cable type for each of the drivers. Connect one set of wires to the bottom set of binding posts (bass driver-specific network). Then connect a second set of wires to the top binding posts (CST-specific network). Next, connect both sets of wires to the appropriate terminals on your amplifier. Take care to connect both (+) wires to the (+) amplifier terminals and both

(–) wires to the (–) amplifier terminals, as shown below.

Bi-Amplification Connections

Bi-Amplification allows the best performance when using dedicated amplifiers for lowand mid-to-high-frequency sections. There are two possible configurations, commonly referred to as horizontal and vertical bi-amping.

Caution

Remove the shorting links before connecting speaker cables in bi-amplifications connections. Failure to do so may result in damage to your amplifiers.

Vertical Bi-Amping

With this configuration, identical stereo amplifiers are used for each speaker system. One channel of each amplifier drives the low frequency section and the other channel drives the high frequency section, as shown below.

Connect one set of wires and amplifier channel to the bottom set of binding posts (bass driver-specific network).

Then connect a second set of wires and the other amplifier channel to the top binding posts (CST-specific network).

Take care to connect both (+) wires to the (+) amplifier terminals and both (–) wires to the (–) amplifier terminals.

Horizontal Bi-Amping

With this configuration, you may use different stereo amplifiers for the lowand mid-to-high-frequency sections of the speaker system (e.g., tube amplifiers for high frequency and solid state for low frequency). Each channel of one amplifier drives the lowfrequency section of each speaker system and each channel of the other amplifier drives the mid-to-high-frequency section, as shown below.

This method requires that both amplifiers have the same gain; otherwise an imbalance will be heard between the lowand mid- to-high-frequency reproduction from the speaker system. If in doubt, please consult your local dealer.

Attaching/Removing the Grille Cover

This speaker system comes with grille covers which may be attached and removed by:

1To attach the grille cover, line up the holes on the speaker with the inserts on the grill, and press firmly.

2To remove the grille cover, grab it by its bottom with both hands and gently pull toward you to separate the bottom part of the grille from the speaker.

3Slide your hands up to the middle section of the grille, and once again pull gently toward you. This will remove the middle section of the grille from the speaker.

4Finally, repeat this same motion for the top part of the grille, removing the grille entirely from the speaker.

Cleaning the speaker cabinet

With normal use, wiping with a dry cloth should be sufficient to keep the cabinet clean. If necessary, clean with a cloth dipped in a neutral cleanser diluted five or six times with water, and wrung out well. Do not use furniture wax or cleansers.

Never use thinners, benzine, insecticide sprays or other chemicals on or near this unit since these will corrode the surfaces.

Avant de commencer

L’impédance nominale de ces enceintes acoustiques est de 6 Ω. Raccordez ces enceintes à un amplificateur dont l’impédance de charge va de 4 Ω à 16 Ω (un modèle pour lequel “4 Ω–16 Ω” est indiqué sur les bornes de sortie de hautparleurs).

Pour éviter d’endommager les enceintes par une surcharge de puissance, observez les précautions suivantes :

Ne fournissez pas aux enceintes acoustiques une puissance électrique dépassant l’entrée maximale autorisée.

Si vous utilisez un égaliseur graphique pour accentuer les hautes fréquences, n’élevez pas trop le volume de l’amplificateur.

N’essayez pas de pousser un amplificateur de faible puissance à produire un volume sonore élevé, car l’augmentation rapide de la distorsion harmonique pourrait endommager les haut-parleurs.

Précautions d’installation

Lors de l’installation de l’enceinte, veillez à ce qu’elle soit fermement immobilisée et évitez les endroits où sa chute pourrait être dangereuse, notamment lors d’une catastrophe naturelle, telle qu’un séisme.

Ne fixez pas les enceintes sur une paroi ou au plafond, car elles pourraient tomber et provoquer des blessures.

N’installez pas les enceintes en hauteur au plafond ou sur une paroi. Si elles sont mal installées, les grilles pourraient tomber et provoquer des dégâts, voire des blessures.

Mettez votre système audiovisuel hors tension et débranchez-le, puis consultez le mode d’emploi avant de brancher des composants. Prenez soin d’utiliser correctement les cordons de raccordement.

Précautions d’emploi

Ne placez pas l’enceinte sur une surface instable, car en tombant, elle pourrait provoquer des blessures et être endommagée.

N’utilisez pas les enceintes pour produire des sons distordus pendant une longue période, car ceci pourrait provoquer un incendie.

Ne montez pas et ne vous asseyez pas sur les enceintes et ne laissez pas des enfants jouer sur celles-ci.

Ne posez pas d’objets lourds ou volumineux sur le dessus des enceintes.

Ne placez pas d’objets magnétiques tels que des tournevis ou des pièces en métal près du tweeter ou du médium. Comme ces haut-parleurs utilisent des aimants puissants, ces objets pourraient être attirés, provoquant des dégâts aux haut-parleurs ou endommageant leur diaphragme.

ATTENTION

Les bornes des haut-parleurs sont sous une tension ACTIVE DANGEREUSE. Pour éviter tout risque de décharge électrique lors du branchement et du débranchement des câbles de haut-parleur, débranchez le cordon d’alimentation avant de toucher des parties non isolées.

A propos de la série EX

Tirant parti du riche savoir-faire technologique qui a permis de créer la série-phare d’enceintes acoustiques TAD de Pioneer, la série EX a été mise au point afin de proposer ce qu’il y a de mieux dans cette catégorie.

Le design et la production de la série EX résultent d’un effort international qui a fait converger la quintessence des technologies de Pioneer dans le domaine des haut-parleurs.

Technologies à l’appui du S-3EX

CST

La pièce maitresse du système est le haut-parleur concentrique CST (Coherent Source Transducer) qui repose sur les technologies utilisées dans la série TAD. Le diaphragme du tweeter est installé de façon concentrique à la base du cône du médium, constituant ainsi une source ponctuelle, allant de 400 Hz à 100 kHz. Le CST procure un équilibre spectral parfait entre les sons directs et réfléchis qui parviennent aux oreilles de l’auditeur. Il fournit ainsi un son plus homogène dans toute la salle d’écoute et améliore l’image sonore.

Diaphragme en graphite céramique

Le tweeter du CST est muni d’un diaphragme en graphitecéramique qui présente des caractéristiques de rigidité et d’amortissement de haut niveau. Elles en font un des meilleurs matériaux actuellement disponibles pour les enceintes acoustiques haut de gamme. Sa légèreté et sa rigidité exceptionnelles permettent de repousser la résonance du diaphragme bien au-delà de la plage audible.

Pertes internes

Diaphragme en alliage de magnésium

Le haut-parleur médium du CST possède un diaphragme en alliage de magnésium dont la légèreté et les pertes internes élevées assurent un excellent régime transitoire et une coloration minimale des sons médium.

Haut-parleurs de graves

Le Haut-parleur de graves illustré ci-dessous sert de base à l’enceinte acoustique S-3EX. La rigidité de sa membrane provient du matériau composite en aramide/carbone, créé lors de la mise au point du S-1EX. La technologie des circuits magnétiques LDMC, exclusive à Pioneer, a été intégrée afin de réduire la distorsion et de préserver la linéarité, quel que soit le niveau.

Ebénisterie

La forme unique du S-3EX a une fonction bien précise. Afin de synchroniser les temps d’arrivée des sons provenant du CST et des deux haut-parleurs de graves, chacun d’eux est placé sur un baffle incurvé selon le principe de la “precision curve” (cf. L’illustration ci-dessous). Réalisé en MDF (Medium Density Fiberboard) d’une épaisseur allant jusqu’à 100 mm, ce baffle est par ailleurs suffisamment rigide pour contenir la force des hautparleurs. De plus, l’évent Bass-reflex est taillé dans un bloc extrêmement épais de MDF, ce qui réduit les bruits d’air et fournit des graves profonds et clairs.

Filtres

Les filtres n’utilisent que des composants hors pair. Disposés sur le parcours du signal, des bobines à air, des résistances non inductives et des condensateurs à film ont été choisis et optimisés avec soin de sorte que le CST puisse procurer la plus grande transparence possible. Les haut-parleurs de graves font appel à des inductances à noyau en plaque d’acier au silicium pour minimiser la distorsion et les pertes pendant le transfert d’énergie. Tous les composants sont reliés directement à leurs câbles respectifs et non pas à une carte de circuit imprimé, ce qui garantit des pertes minimales et des performances maximales.

Collaboration avec Air Studios

Depuis leur fondation à Londres par George Martin en 1969, les Air Studios ont acquis le respect d’une foule d’artistes qui les considèrent comme les meilleurs studios d’enregistrement au monde. Le label “Air Studios” décerné aux S-3EX indique que ces enceintes acoustiques sont capables de restituer la haute qualité sonore exigée par les ingénieurs du son les plus réputés du monde.

Pattes

1 Choisissez l’emplacement de l’enceinte, puis placez les bases des pointes de découplage sur le sol.

2Placez l’enceinte sur les bases de pointes de découplage.

3Si la patte arrière gauche ou droite touche le sol avant la pointe de découplage arrière, empêchant l’enceinte de reposer à plat sur sa surface d’emplacement, ajustez la pointe de découplage arrière de sorte qu’elle touche le sol avant les pattes arrière.

4Placez les cales de liège fournies sous les pattes arrières pour stabiliser l’enceinte.

Parmi les différents types fournis, choisissez les cales ayant l’épaisseur la plus appropriée.

Cales de liège

Fixation de l’attache antichute

Au moyen de la vis fournie, fixez fermement l’attache sur la face arrière de l’enceinte.

Faites passer un cordon suffisamment solide, disponible dans le commerce, dans l’attache pour relier l’enceinte à une paroi. Assurez-vous que celle-ci est suffisamment résistante pour supporter le poids de l’enceinte. Après la fixation de l’enceinte, assurez-vous qu’elle ne puisse pas tomber.

Si elle devait tomber, l’enceinte subirait des dégâts.

Ne fixez pas l’attache directement sur une paroi, Elle doit être utilisée uniquement avec un cordon pour prévenir la chute de l’enceinte.

Attache

Cordon suffisamment solide

Face arrière de l’enceinte

Faites passer deux cordons renforcés par l’attache et fixez l’enceinte sur une paroi comme illustré ci-dessus.

N’installez pas les enceintes en plein soleil et évitez de les placer près d’appareils de chauffage ou de climatiseurs, car ceci pourrait gondoler et décolorer les enceintes et endommager leurs haut-parleurs.

Pioneer n’assume aucune responsabilité en cas de dégâts causés par un assemblage et un montage inadéquats, un renforcement insuffisant, une erreur d’utilisation, des catastrophes naturelles, etc.

Ne placez pas l’enceinte sur une surface instable, car en tombant, elle pourrait provoquer des blessures et être endommagée.

Par mesure de précaution, ne placez pas l’enceinte à un endroit où, en cas de séisme, elle pourrait tomber sur une personne pendant son sommeil.

Comme l’enceinte pèse environ 48 kg, il est dangereux d’essayer d’ajuster l’écrou de la pointe de découplage en inclinant l’enceinte. Posez l’appareil sur une surface douce, telle qu’une couverture, de sorte qu’elle n’abîme pas le plancher et procédez à deux personnes au moins pour effectuer l’installation.
