Mounting your Speakers

The speaker's foot bracket can be used to set the speaker on shelving, or to mount the speaker to the

walls or ceilings. A clamp ring and four clamp screws hold the foot bracket to the speaker. Mount the

foot bracket to a wall or ceiling using screws through the two holes in the foot bracket. Removing the

foot bracket from the speaker may make mounting easier. After mounting, aim the speaker on its

ball/swivel mount by loosening the clamp screws, adjusting the speaker, and retightening the screws.

Do not try to re-aim the speaker without loosening the screws as this may damage the ball/swivel

mount. Be sure that both the fasteners and the mounting surface can safely support the weight of the

speaker, especially in earthquake prone regions.

Setting up and installing home cinema systems

The three-dimensional drawing on Pg.13, (Fig. 1), shows a typical configuration for a home cinema setup

in a living room, using two floor-standing speakers and a special center speaker as the front speakers.

Please study the manufacturers' instruction manuals carefully before connecting the equipment.

Bi-wiring and bi-amping

In conventional systems, the speaker connection cables carry all the frequencies together. The bass

signals have much more power, however, this can cause losses in overall sound quality. "Bi-wiring,"

which means dividing the signal and using one set of cables for the high frequencies and another for the

low frequencies, can bring an audible improvement in sound quality. "Bi-amping" goes one step further

by using separate amplifiers as well as separate cables for the high and low frequency ranges. This

method eliminates sound losses caused by the widely-different current levels in the lower and upper

ranges by separating the signals right from the very start. Some AR speakers have specially designed

connection terminals that can be used both for conventional operation and for bi-wiring/bi-amping.

This means that if you wish, you can use separate connections for the woofer and the mid/tweeter units.

There are four screw terminals on each speaker: the top two are for the mid-range and tweeter units,

the bottom two for the woofers.

When the speakers are delivered from the factory, the upper and lower terminals are connected with

jumpers for operation in conventional mode (see Pg. 16, Fig. 1).

If you just wish to use one cable, simply leave the jumpers in place and connect the cable to either the

upper or the lower terminals - which pair you use makes no difference.

If you wish to operate the speakers in bi-wiring/bi-amping mode, you must first remove the two jumpers

from each speaker.

For bi-wiring (Pg.16, Fig. 2) you need two cables for each speaker and amplifier channel, or a special bi-

wiring cable. Connect the two cables to the amplifier outputs in parallel - i.e., connect both positive

EXPLANATION OF FEATURES AND CONTROLS

Refer to Figure A and "Connecting Your ARXP410P Speakers"

1) Power Switch: This two position switch controls the power status of the subwoofer.

Off: Turns the unit off.

On: Turns the unit on regardless of whether a signal is present or not.

2) LFE INPUT JACK: Allows direct connection from the amplifier/processor with an internal low pass filter. This connection bypasses

the subwoofer internal crossover circuitry. Use only with appropriate Surround Sound processor/amplifier.

3) Speaker input: These screw terminals for speaker wire accept a stereo speaker level, full range signal from a receiver or power

amplifier. This signal is processed and amplified to power the subwoofer. (Please see Connecting your XP410P speakers)

4) Fuse: For continued protection replace fuse with same type and size listed.

5) Level control: This rotary control adjusts the level of the subwoofer and is used to balance its volume with that of the main stereo speakers.

6) Status LED: This light emitting diode shows the status of the subwoofer electronics. "Red" indicates that the amplifier is plugged in

and the power switch is on.The LED will turn green when the amplifier detects a signal.

EXPLICATION DES FONCTIONS ET COMMANDES :

Voir le schéma ou a "Raccorder vos Enceintes Acoustiques ARXP410P"

1) Interrupteur de mise en marche/arrêt: Cet interrupteur à deux positions contrôle le statut de la mise en/hors fonction du haut-parleur d'ex-

trêmes graves.

Hors fonction 'OFF': Met l'appareil hors fonction.

En fonction 'ON': Met l'appareil en marche, peu importe si l'appareil détecte un signal ou non.

2) PRISE D'ENTRÉE DES EFFETS DE BASSES FRÉQUENCES 'LFE' : Permet le raccord direct depuis l'amplificateur ou le

processeur doté d'un filtre passe-bas interne. Ce raccord permet de contourner le circuit séparateur de fréquences interne du haut-

parleur d'extrêmes graves. Utilisez uniquement cette prise avec le processeur/amplificateur ambiophonique approprié.

3) Données de 'Haut-parleurs': Ceux-ci vissent des terminaux pour les fils des haut-parleurs, acceptent un signal de niveau élevé (haut-par-

leurs) stéréo de pleine gamme provenant d'un récepteur ou d'un amplificateur. Ce signal est transformé et amplifié pour alimenter le haut-

parleur d'extrêmes graves. (Voir Connectant s'il vous plaît votre XP410P haut-parleurs)

4) Fusible: Pour offrir une protection continue, remplacez le fusible par un fusible du même type et du même calibre.

5) Commande de niveau : Cette commande rotative ajuste le niveau du haut-parleur d'extrêmes graves et sert à équilibrer son volume avec

celui des haut-parleurs stéréo avant.

6) Voyant à DEL du statut : Cette diode électroluminescente affiche le statut des composantes électroniques du haut-parleur d'extrêmes

graves. Lorsque le voyant brille en rouge, ceci indique que l'amplificateur est bien raccordé à la prise de courant. Le MENE tournera vert

quand l'amplificateur détecte un signal.

DEFINICIÓN DE LAS CARACTERÍSTICAS Y LOS CONTROLES

Consulte la figura A y "Conexión de los Altavoces ARXP410P"

1) Interruptor de la potencia: Este interruptor para encender y apagar controla el estado de la potencia del subwoofer.

Off (apagado): Apagada la unidad

On (encendido): Enciende la unidad aunque la señal no esté presente.

2) Enchufe de entrada LFE: Le permite la conexión directa del amplificador/ procesador con un filtro de paso bajo interno. Esta conexión

sobre pasa el circuito en cruz interno del subwoofer. Úselo solamente con un amplificador/ procesador de sonido envolvente apropiado.

3) Entrada del altavoz: Estas terminales con tornillo para el cable del altavoz aceptan una señal en estéreo de alcance total del recep-

tor o del amplificador. Esta señal es trasmitida y amplificada para alimentar el subwoofer. (Ve por favor Conectando sus oradores

XP410P)

4) Fusible: Para una protección continua reemplace el fusible con otro del mismo tipo y tamaño.

5) Control del nivel: Este control rotatorio ajusta el nivel del subwoofer y se usa para balancear su volumen con el de los altavoces principales.

6) LED de estado: Este diodo que emite luz enseña el estado de la electrónica del subwoofer. "Rojo" indica que el amplificador está conectado.

El DIRIGIDO girará verde cuando el amplificador discierne una señal.
