AAL SERIES SPEAKERS
Congratulations on your purchase of AAL Home Loudspeakers. Your new loudspeakers
represent years of thorough research and development in the most modern techniques of speaker
design and engineering. Using advanced technology and high quality electronics and compo-
nents, AAL loudspeakers assure you of exceptional performance and value.
Your speakers were examined very carefully during and after manufacturing to assure all
quality standards were met or exceeded. If damage as a result of shipping and handling has
occurred, please contact the shipper or your dealer immediately.
Thank you for selecting AAL when you made your audio equipment purchase.
FEATURES
• Bass Reflex Enclosures
All AAL Series Loudspeakers provide efficient, low bass response by utilizing a vented/bass
reflex enclosure design. This design provides optimum low frequency response and maximum
efficiency.
• Tweeter
Your AAL system uses a Piezo (or piezo-electric) tweeter which contains a piezoelectric crys-
tal coupled to a mechanical diaphragm. The dynamic mass of the piezo tweeter offers a response
which is very fast. Piezo tweeters offer a quality high-frequency sound source in a rugged, high-
efficiency package.
• Mid-bass (10" and 12" Models)
By utilizing a mid-bass driver, your system functions well in the region which contains most
sounds which are the most familiar to the human ear, including fundamental musical instruments
and, most importantly, human voice.
• Low Frequency Drivers
The woofers in all AAL systems utilize Finite Element Analysis (FEA) designed motor struc-
tures with high temperature aluminum voice coil formers, and massive strontium ferrite magnet
assemblies for maximum energy transfer and excellent cone control. A composite pulp cone and
foam surround completes the woofer design. This configuration provides optimum low frequency
response and maximum efficiency.
• Quality
With a very strong manufacturing heritage, American Acoustics has built its reputation by
utilizing a vertically integrated approach to manufacturing. This allows American Acoustics to
control every aspect of the manufacturing process - from design to production - for exceptional
product quality.
GUIDELINES FOR SPEAKER PLACEMENT
Your new AAL Loudspeaker system has been engineered to provide deep powerful bass and
crisp, natural high frequency performance in a wide variety of installations. Because no two rooms
are exactly alike, there are no exact rules for speaker placement. There are, however, several
steps you can take to maximize your listening enjoyment.
Avoid placing your loudspeakers at opposite ends of the room if possible. This can result in
the undesirable effect called the "hole in the middle". Keeping the speaker system on the same
wall will enhance the stereo effect or "image". Try to place the speakers so that they form an
equilateral triangle with your seating position, and aim or "toe-in" the speakers so that the tweeters
face you like a camera lens.
Depending on your preference, bass output can be increased by placing the speakers near
walls or in corners. Experiment to find the low frequency performance you enjoy most.
If the speaker system is placed near the ceiling, on top of a book case or entertainment unit,
try to aim the speakers down into the listening area. Always make sure they are stable and will
not fall. Whenever you place a speaker on a shelf or bookcase, be sure it can support the weight
safely. Should you need to lay the speakers on their sides, keep the tweeters at opposite ends to
maintain a balanced sound.
You must be the final judge as to where your new AAL loudspeakers perform best. With that
in mind, you will find it worth while to take time to familiarize yourself with the performance and
experiment with their placement to determine where they provide the best frequency balance and
stereo effect.

RACCORDEMENT DES ENCEINTES AU SYSTÈME
Il existe de nombreuses sections de fils d'enceintes, mais AAL recommande l'utilisation de fils
d'au moins 0,78 mm2 de section (calibre 18) pour le raccordement des enceintes à l'amplificateur
ou au récepteur.
Avant de couper les fils d'enceintes aux longueurs voulues, veillez à laisser 60 à 90
centimètres d'excédent pour le cas ou vous auriez à déplacer un peu les enceintes. À l'aide d'une
pince à dénuder ou d'un couteau bien tranchant, dénudez les deux extrémités du fil sur 13 mm
environ. Torsadez les fils dénudés afin de faciliter leur insertion dans les bornes de l'enceinte.
Avant de poursuivre, veillez à débrancher l'amplificateur du récepteur.
Il est essentiel de raccorder les enceintes « en phase ». Pour cela, déterminez d'abord quel
codage utilise le câble d'enceinte pour distinguer les deux fils qui le composent.
Pour raccorder les enceintes en phase, veillez à raccorder les bornes positives (+) à l'arrière
du récepteur avec les bornes rouges à l'arrière des enceintes, et les bornes négatives (-) du
récepteur aux bornes noires des enceintes. Sachez que les bornes négatives (-) du récepteur
peuvent aussi être identifiées comme « commun » ou « masse ».
Vérifiez sur l'enceinte comme sur le récepteur qu'aucun brin de fil n'aille d'une borne à l'autre,
afin d'éviter tout endommagement par court-circuit.
Si vous n'êtes pas sûr que les enceintes soient en phase, placez les enceintes près l'une
de l'autre et face à face, et écoutez un morceau contenant des graves. Tournez la commande
d'équilibrage du récepteur ou du préamplificateur au maximum vers la gauche, puis vers la droite
en vous arrêtant en position centrale. Le système doit produire le volume de graves maximal en
position centrale. Si ce n'est pas le cas, inversez les fils sur l'une des enceintes et refaites l'essai.
Le branchement donnant le volume de graves le plus élevé est le bon.
