FOIRE AUX QUESTIONS - AE2 MkII Acoustic Energy

Comment effectuer le bi-câblage des enceintes AE2 MkII ?

Pour le bi-câblage, retirez les links de court-circuit entre les bornes HF et LF. Connectez ensuite deux paires de câbles depuis l'amplificateur : une paire vers les bornes HF (aigu) et une vers les bornes LF (grave). Respectez la polarité : câble nervuré au positif (+), câble lisse au négatif (-).

Puis-je placer les enceintes sur des étagères ?

Oui, mais la surface doit être ferme. Utilisez des cônes, de la feutrine ou des patins antivibratiles sous les enceintes pour éviter les résonances.

Quelle est la puissance d'amplification recommandée ?

Les enceintes acceptent des amplificateurs jusqu'à 250 watts. Il est conseillé de choisir un amplificateur de qualité avec une puissance adaptée à la pièce et au niveau d'écoute.

Comment nettoyer les enceintes AE2 MkII ?

Utilisez un chiffon doux et sec pour dépoussiérer les surfaces. Pour les grilles magnétiques, retirez-les avec précaution et nettoyez-les séparément si nécessaire.

Quelle est la fréquence de coupure du filtre ?

Le filtre est un 6 éléments avec une pente de 6 dB/octave à 3 kHz, répartissant les fréquences entre le tweeter et les haut-parleurs médium/grave.

Faut-il retirer les grilles pour une meilleure écoute ?

Oui, pour une écoute sérieuse, il est préférable de retirer les grilles afin d'obtenir la meilleure transparence possible. Manipulez les grilles magnétiques avec soin.

À quelle distance des murs placer les enceintes ?

Placez les enceintes entre 40 et 120 cm des murs latéraux et arrière pour obtenir une image stéréo optimale. Les dimensions critiques (hauteur, distance aux murs) doivent être différentes pour chaque enceinte.

Comment brancher les enceintes en bi-amplification ?

Pour la bi-amplification, utilisez deux amplificateurs : un pour la section grave (LF) et un pour la section aiguë (HF). Connectez les câbles en respectant la polarité sur les bornes correspondantes, comme pour le bi-câblage.

Que faire si une enceinte ne fonctionne pas ?

Vérifiez d'abord les connexions, la polarité et que l'amplificateur est allumé. Si le problème persiste, contactez votre revendeur ou le service après-vente Acoustic Energy.

Quelle est la garantie des enceintes AE2 MkII ?

Les enceintes sont garanties 5 ans contre tout défaut de matériaux et de fabrication, à compter de la date d'achat. Cette garantie couvre la réparation ou le remplacement des pièces défectueuses (Royaume-Uni).

AE2

SERIES II

Owner's manual

(AE)

ACOUSTIC ENERGY

Congratulations on choosing the Acoustic Energy AE2 Series II — a high power, compact two-way loudspeaker which is capable of outstanding performance with exceptional power handling, transparency, dynamics and low distortion.

Please take a few moments to read this manual. The advice it contains will enable you to get the optimum performance from your AE loudspeakers.

The AE2 Series II is closely based on the Acoustic Energy AE1 loudspeaker and employs its proven metal cone drivers. The twin mid-bass drivers use triple-layer, anodised metal diaphragms which ensure pure piston performance with exceptional rigidity. Acting also as a heat sink for the bonded voice coil, this metal cone limits the thermal compression effects that inhibit conventional drive units.

The tweeter, or treble driver, is a magnesium alloy metal dome unit matching the 'speed' and clarity of the rest of the system.

New developments already proven in the AE2 Signature have been applied to the AE2 Series II. The crossover features upgrades to the main components and the internal wiring is Teflon™ insulated, twisted-pair, silver-plated OFC (Oxygen Free Copper). Industrial grade encapsulation is also applied to the total crossover assembly eliminating resonance and microphony, and increasing power handling.

Additional optimum cabinet bracing between the drive units has increased transient definition beyond current standards.

Rigid support is essential for the speaker to develop its full detail and dynamic performance. Rigid stands with spikes or cones are recommended — Acoustic Energy produces a dedicated matching stand — the STAE2. If the AE2s are to be shelf mounted the support must be firm; cones, felt or similar anti-vibration pads are recommended beneath the cabinets.

The widest, most focused and spacious stereo images require free-field use, with the speakers located away from side walls and the rear wall by approximately 40 to 120 cm. Ideally, each speaker should be symmetrically placed in the left and right locations, but with the three critical dimensions for speaker locations — height from the floor, distance to the side wall and finally to the rear wall — non-coincidental. This will give the most uniform and extended bass with best mid-range accuracy.

The tweeters should be at, or above ear height placed outermost to provide the designed, time delay correction.

If used horizontally on a mixing desk, the tweeters should be uppermost, ie. above head level. The compact nature, superb dynamics and high power handling of this speaker qualifies the Reference Series as top flight, near-field monitors as well as superb domestic free-field designs.

For serious listening speaker and tweeter grilles are best removed — please ensure extreme care is used when removing and replacing the magnetic tweeter grille.

Experiment with the best position and trust your own judgement and ears.

Check that your amplifier is switched off before installing your loudspeakers. Failure to do so may result in speaker or amplifier damage. The diagrams illustrate one loudspeaker only.

Conventional

Normal passive wiring requires shorting links to be in place between the treble and mid/bass sections. The positive (ribbed) cable from the amplifier positive (or red) terminal should connect with the positive (red) terminal on the loudspeaker. Similarly the negative (smooth) cable should connect the amplifier negative terminal (black) to the negative terminal (black) on the loudspeaker.

Bi-wiring

Bi-wiring separates the bass and treble ground paths in the loud-speaker and offers great sound quality advantages. An extra set of cables is required.

Note that the shorting links are removed between the treble and mid/bass sections and should be stored for later use if conventional, passive driving is required.

Two pairs of cables are connected to the amplifier terminals.

One cable of each pair should connect to the HF or treble section and one to the LF or bass section. The positive (ribbed) cables from the amplifier positive (or red) terminal should connect with the positive (red) terminals on the loudspeaker.

Similarly the negative (smooth) cables in each pair should connect the amplifier negative terminal (black) to the negative terminals (black) on the loudspeaker.

Bi-amping

Bi-amping adds a second amplifier to the system. One power amplifier drives the treble section of both loudspeakers; a second drives the mid/bass sections.

As regards the loudspeakers, wiring for bi-amping is achieved in much the same way as bi-wiring. Treble amplifier positive (red) terminal should be connected via the ribbed cable to the positive (red) HF terminal on the speaker. Similarly, treble amplifier negative is connected to the negative (black) HF terminal on the speaker. Repeat this process with the bass amplifier and LF terminal pair.

After wiring up

Lower the volume to minimum, switch on the amplifier, select the signal source and then raise the volume to the listening level required.
