Empfängt er 20 Minuten lang kein Signal, schaltet er wieder in den Standby-Modus. Ist der Subwoofer aktiviert, leuchtet die Betriebsanzeige grün; leuchtet die LED rot, befindet sich der Subwoofer im Standby-Modus.Steht der Power-Schalter auf …On“ bleibt der Subwoofer•ständig aktiviert. Steht der Power-Schalter auf "On" bleibt der Subwoofer ständig aktiviert, und die LED leuchtet grün.Verwenden Sie den Subwoofer über einen längeren Zeitraum nicht (zum Beispiel während der Sommerferien), sollten Sie den Power-Schalter auf …Off“ stellen und ihn damit vollständig ausschalten.SUBWOOFER-BEDIENELEMENTE: CROSSOVER-REGLER:HINWEIS: Der Crossover-Regler wirkt nur, wenn das Signal über die Line-Level In L/R-Eingänge empfangen wird. Das am Line-Level In LFE-Anschluss anliegende Signal durchläuft weder den Crossover-Regler noch die eingebaute Frequenzweiche.Mit dem Crossover-Regler können Sie die obere Grenzfrequenz des Subwoofers im Bereich zwischen 50 und 200 Hz justieren. Je höher Sie die obere Grenzfrequenz einstellen, desto größer ist der mitden Satelliten-Lautsprechern überlappende Frequenzbereich. Auf diese Weise sorgen Sie selbst in Wohnräumen mit schwierigen akustischen Eigenschaften und unabhängig vom Aufstellungsort des Subwoofers für einen gleichmäßigen Frequenzübergang zwischen den Satelliten-Boxen und dem Bass-Lautsprecher.Achten Sie auf eine gleichmäßige Basswiedergabe in Ihrem Hörraum. Werden bestimmte Basstöne überbetont, sollten Sie eine niedrigere obere Grenzfrequenz ausprobieren. Wirken bestimmte Basstöne schwach, können Sie das Klangbild mit einer höheren oberen Grenzfrequenz verbessern.SUBWOOFER-BEDIENELEMENTE: SUBWOOFER LEVELMit diesem Regler können Sie die Lautstärke des Subwoofers justieren. Drehen Sie den Regler im Uhrzeigersinn, um die Lautstärke zu erhöhen. Drehen Sie ihn gegen den Uhrzeigesinn, um die Lautstärke zu mindern. Haben Sie einmal eine ausgeglichene Lautstärke zwischen Satelliten und Subwoofer gefunden, sollten Sie diese Einstellung nicht mehr verändern.Hinweise zur korrekten einstellung der Subwoofer-Lautstärke:Manchmal ist die ideale Lautstärke für Musik zu laut für die •Wiedergabe von Filmen und umgekehrt. Deswegen sollten Sie für die Einstellung der Subwoofer-Lautstärke bassbetonte Filme und Musikstücke verwenden – wählen Sie einen Durchschnittswert, der zu beiden Inhalten passt.Klingt Ihr Subwoofer ständig zu laut oder zu leise, wählen Sie •bitte einen anderen Aufstellort. Rücken Sie den Subwoofernäher in eine Zimmerecke, wird die Bass-Wiedergabe verstärkt. Vergrößern Sie den Abstand zur nächsten Wand, wird der Bass schwächer.SUBWOOFER-BEDIENELEMENTE: PHASE Dieser Schalter legt fest, ob sich die Bassmembran des Subwoofers und die Membranen der Satelliten-Lautsprecher synchron oder gegenläufig bewegen. Bewegen sich die Membranen nicht synchron, löschen sich einige Bassfrequenzen des Subwoofers oder der Satelliten gegenseitig auf, wodurchBassleistung und Dynamik sinken. Dieser Effekt hängt überwiegendermaßen vom Aufstellungsort der Lautsprecher im Raum ab.In den meisten Fällen können Sie den Phasen-Schalter auf …Normal“ belassen – eine wirklich …richtige“ Einstellung gibt es dennoch nicht. Spielen Subwoofer und Satelliten in Phase, bleibt das Klangbild klar und packend – dynamische Instrumente wie Schlagzeug oder Klavier klingen besonders naturgetreu. Am besten gehen Sie wie folgt vor, um die Phase Ihres Subwoofers korrekt einzustellen: Legen Sie Musik auf, die Sie sehr gut kennen. Stellen Sie den Phasenschalter so ein, dass Schlagzeug und Bass lauter klingen. Korigieren Sie anschließend evtl. die Lautstärke mit dem Subwoofer-Level-Regler mit höchster Dynamik wiedergegeben werden.© 2010 HARMAN International Industries, Incorporated.

It enables us to keep you posted on our latest advance-ments, and helps us to better understand our customers and build products that meet their needs and expectations.INCLUDEDCarefully unpack the system. If you suspect damage from transit, report it immediately to your dealer and/or delivery service. Keep the shipping carton and packing materials for future use. Open the package and verify the following contents:(2) Speakers (2) Adjustable wall (2) Fixed wall brackets with bracketstightening barPLANNING YOUR SYSTEMBefore deciding where to best place your speakers, survey your room and study Figures 1 and 2.Figure 1. In this overhead view of a typical installation, satellite speakers are used to reproduce sound for the front and surround channels. The center channel reproduces sound and dialogue. The powered subwoofer provides bass for effects and music.Figure 2. This figure shows an alternative layout, which may be more suitable for some rooms.PLACEMENT NOTE:The CS400SAT can be placed directly on a shelf, or mounted on a wall using the included wall brackets. As Left and Right Front Channels For left and right front channels, place one satellite to the left and another to the right of the television, as shown in Figure 1. Since the speakers are magnetically shielded, you can place them very close to the TV without worrying about the magnetic field distorting the picture.As Surround Channels For left and right surround channels, place one speaker on the left and another on the right, to the side of or slightly behind the listening area. The surround speakers should be mounted at a height of between 5 ft. (1.5m) and 7 ft. (2m).In 7-channel configurations, place the rear channel(s) behind the listening position, as shown in Figures 1 and 2. NOTE:A powered subwoofer will add impact and realism to both music and film soundtracks. Contact your JBL dealer for recommendations on subwoofer models for your application.Mounting on Floor Stands An optional floor stand is available, should you prefer to place your CS400SAT satellites on the floor; see your dealer or visit for more information.Left Rear Channel Left Surround Channel Right Surround Channel Right Rear Channel Left Front Channel Subwoofer Right Front Channel Center Channel CouchLeft Rear Channel Left Surround Channel RightSurroundChannelRight Rear Channel Left Front Channel SubwooferRight FrontChannelCenter Channel THANK YOU FOR CHOOSING JBL 3The CS400SAT is designed to be mounted on the wall. There is a fixed-mount wall bracket and an adjustable wall bracket provided for each satellite. Each speaker bracket will require up to four 1-1/2"#10 wood screws; each screw should be fastened to a wall stud. If a wall stud is unavailable, install an anchor appropriate for a 1-1/2"#10 screw.NOTE:The customer is responsible for the correct selectionand use of mounting hardware (available through hardware stores) that will ensure the proper and safe wall-mounting of the speakers.Fixed-Mount Wall BracketStep 1.Mark the positions on the wall where you would liketo place the mounting screws.Step 2.Attach the bracket to the wall using two screws(not included).Step 3.Remove the rubber ring on the bottom of the satellite,and sit the satellite onto the back bracket.Step 4.Attach 1/4-20 screw into insert on bottom of speakerand tighten.Adjustable Wall BracketStep 1.Remove cap over threaded insert on rear of speakerStep 2.Mark the positions on the wall where you would like to place the mounting screws.Step 3.Place bracket against the wall and fasten four 1-1/2" #10 wood screws through the bracket’s screw holes into the wall. If a wall stud is not available, use an appropriate anchor.Step 4.Unscrew round collar (C) from bracket (A).Step 5.Screw the ball and shaft assembly (B) to the 1/4"-20 insert on the back of the satellite (do not use the bottom insert on the speaker). Back out 1/2 of a turn and tighten the nut against the speaker. If the ball and shaft assembly is not backed out before tightening the nut, performing Step 8 below may dislodge the threaded insert in the speaker housing and permanently damage the speaker.Step 6.Attach speaker wire as shown on page 5.Step 7.Drop round collar (C) over ball and shaft assembly (B) that is mounted to the speaker with the finished side of the collar facing the rear of the speaker.Step 8.Carefully push the ball straight into the socket mounted on the wall, angle the speaker as desired and tighten the collar using the enclosed metal bar.Figure 3. Bracket on wall.Metal barMetal barABCWALL-MOUNTING THE SA TELLITES4CONNECTIONSAfter placing the speakers, you are ready to connect your system. First, turn off all audio-system power. Use high-quality speaker wire to make your connections; #18-gauge speaker wire with polarity cod-ing is recommended. For longer distances, #16-gauge or heavier wire is recommended. The side of the wire with a ridge or other coding is usually considered positive polarity (i.e., +). Also, consult the owner’s manuals that were included with your amplifier or receiver to confirm connection procedures. Observe polarities when making speaker connections, as shown in Figure 4. Connect each + terminal on the back of the amplifier or receiver to the respective + (red) terminal on each speaker. Connect the – (black) terminals in the same way. Important!Do not reverse polarities (i.e., + to –, or – to +) when making connections. Doing so will cause poor imaging and diminishedbass response. Be certain that positive and negative wire strands are completely isolated to avoid short circuits that may damage your equipment.NOTE:On certain models using hexagonal terminal nuts, a small socket wrench is provided to help in properly tightening the terminals. Hand-tighten only and do not overtighten.Figure 4. Wiring diagram shows polarity connectionsfor one channel of a home theater system.MAINTENANCE AND SERVICEThe enclosure may be cleaned using a soft cloth to remove finger-prints or to wipe off dust.All wiring connections should be inspected and cleaned or remade periodically. The frequency of maintenance depends on the metals involved in the connections, atmospheric conditions and other fac-tors, but once per year is the minimum.If a problem occurs, make sure that all connections are properly made and clean. If a problem exists in one loudspeaker, reverse the connection wires to the left and right system. If the problem remainsin the same speaker, then the fault is with the loudspeaker. If the problem appears in the opposite speaker, the cause is in another component or cable. In the event that your speaker ever needs service, contact your local JBL dealer or distributor, or visit for a service center near you.5Laurent RaultJBL is a trademark of Harman International Industries, Incorporated, registered in the United States and/or other countries.

JBL HTI系列墙内音响系统用户指南说明书

GUIA DEL PROPIETARIOESPAÑOL2INCLUYEPlantilla / pieza pintada.Un par de altavoces con rejilla.GRACIAS POR ELEGIR JBLHTI6,HTI8HTI6CDurante más de 50 años, JBL ha jugado un papel importante en cada uno de los aspectos en los procesos de grabación y reproducción de música y películas, desde actuaciones en directo hasta reproduccio-nes en el estudio, en su casa o en la oficina.Estamos seguros de que los altavoces JBL que ha elegido le proporcionarán toda la satis-facción sonora que espera de ellos, y de que cuando necesite adquirir algún equipo de audio adicional para su casa, su coche o su oficina, volverá a elegir JBL.Tómese un momento para registrar su producto en la página web . Nos permitirá mantenerle informado de nuestras más recientes novedades, y nos ayudará a entenderle mejor y a fabricar productos de acuerdo con sus deseos y necesidades. JBL Consumer ProductsHTI55Altavoz con rejilla. El logo se colocará en la rejilla depen-diendo de su instalación verti-cal u horizontal.Plantilla / pieza pintada.3ALTAVOCES FRONTALES (HTI6,HTI8,HTI55)MODELOS HTI6,HTI8 Y HTI55 COMO ALTAVOCES TRASEROSMODELOS HTI6C EN EL TECHOUBICACION DEL ALTAVOZUna adecuada ubicación de los altavoces es un paso importan-te para conseguir una repro-ducción sonora eficiente. Las siguientes recomendaciones tratan sobre cómo conseguir una adecuada colocación de los altavoces. Utilícelas como una guía. Pequeñas variacio-nes no modificarán la calidad de escucha. Los altavoces fron-tales deberán guardar entre ellos la misma distancia que guardan respecto a la posición de escucha. También deberán colocarse aproximadamente a la misma altura en que seencuentran la posición de escucha, con los altavoces de agudos en línea con los oídos del usuario.El modelo HTI55 es adecuado para las posiciones frontales izquierda, central y derecha.También puede ser utilizado como altavoz surround lateral o trasero. Se puede colocar tanto horizontalmente como vertical-mente, pero asegúrese de que los instala de manera que todos los altavoces de agudos de los altavoces frontales quedan a la misma altura (o no difieren en su posición en más de 60 centí-metros). Puede hacer girar el altavoz de agudos para colocar el logo de JBL en su posición correcta.En una configuración de cine doméstico, los dos altavoces surround deberán colocarse ligeramente por detrás de la posición de escucha, apuntán-dose entre ellos y ligeramente más altos que la posición de escucha. Si esto no es posible,deberá colocarlos en la pared (o en el techo), por detrás de la posición de escucha, mirando hacia adelante.En los sistemas de 6.1 y 7.1canales deberá colocar los altavoces surround traseros en la pared trasera. Los altavoces surround no deben tener un papel protagonista. Deberán proporcionar un sonido de ambiente difuso que acompaña al material de programa princi-pal que sale de los altavoces frontales. En los sistemas Dolby Digital y DTS ®, deberá dirigir los altavoces de agudos hacia la posición de escucha, a la altura de posición de escucha.E S P A ÑO L4Destornillador Phillips #2Cinta métrica CúterLápizde burbujaDestornilladorHERRAMIENTAS NECESARIASLa serie de altavoces de pared JBL HTI ha sido diseñada para una instalación fácil. Aún así, si usted no se ve capaz de instalar correctamente los altavoces, no dude en contac-tar con su distribuidor o con un instalador profesional.INSTALACIONLa mayoría de fabricantes de altavoces y de electrónica,incluyendo JBL, utilizan el color rojo para simbolizar el terminal positivo y el color negro para representar el terminal nega-tivo (-). Es importante conectar los altavoces de manera idén-tica: el símbolo (+) del altavoz con el símbolo (+) del amplifica-dor, y el símbolo (-) del altavoz con el símbolo (-) del amplifica-dor. Una conexión en contra-fase provocaría un sonido débil, con deficiencia en los graves y con una imagen esté-reo muy pobre. En los sistemas de sonido surround multicanal,la correcta polaridad continua siendo de vital importancia para conservar la buena repro-ducción y la direccionalidad del material sonoro.LONGITUD DE CABLE TAMAÑO RECOMENDADOHasta 6 metros.calibre 16 Hasta 9 metros. calibre 12Más de 9 metros. calibre 10Los cables de altavoz deberán tener la misma longitud. Si uno de los altavoces se encuentra más cercano al amplificador que otro, esconda el cable sobrante. Los altavoces y los terminales tienen su polaridad (+) y (-) correspondiente.CONEXIONES DE LOS ALTAVOCES5HTI6,HTI8,HTI55INSTALACION EXISTENTERetire la rejilla del marco del altavoz tirando de la lengüeta de papel.

The HF driver delivers excellent sound quality from a hybrid diaphragm of deep drawn titanium and resonance-absorbing polyimide, coupled to a patented low compression, low resonance phase plug for very low distortion performance with abundant headroom.The rotatable 13-inch (330mm) HF waveguide provides well-defined coverage and a smooth off-axis response that enhances arrayability. Individually voiced crossovers produce proper beamwidth matching transitions and identical sonic signatures, permitting horn patterns to be mixed throughout an installation. Additionally, user selectable single-amp or biamp operating modes expand application flexibility.I SERIESPoint Source 600IP6-1152/64MEDIUM POWER 15-INCH TWO-WAY60° x 40° INSTALLATION LOUDSPEAKERI SERIES Point Source 600IP6-1152/64MEDIUM POWER 15-INCH TWO-WAY 60° x 40° INSTALLATION LOUDSPEAKERHORIZONTAL POLAR DATA (30dB Scale, 6dB per major division)VERTICAL POLAR DATA (30dB Scale, 6dB per major division)-6— 100 Hz — 125 Hz — 160 Hz — 200 Hz-90° right 45°135°90° left-45°-135°0°front180°back — 250 Hz — 315 Hz — 400 Hz — 500 Hz— 630 Hz — 800 Hz — 1000 Hz — 1250 Hz-90° right 45°135°90° left-45°-135°0°front 180°back-90° right 45°135°90° left-45°-135°0°front180°back — 10000 Hz — 12500 Hz — 16000 Hz-90° right45°135°90° left-45°-135°0°front180°back — 4000 Hz — 5000 Hz — 6300 Hz — 8000 Hz-90° right45°135°90° left-45°-135°0°front 180°back — 1600 Hz — 2000 Hz — 2500 Hz — 3150 Hz-90° right45°135°90° left-45°-135°0°front 180°back -6— 100 Hz — 125 Hz — 160 Hz — 200 Hz-90° down 45°135°90° up-45°-135°0°front180°back — 250 Hz — 315 Hz — 400 Hz — 500 Hz— 630 Hz — 800 Hz — 1000 Hz — 1250 Hz-90° down 45°135°90° up-45°-135°0°front 180°back-90° down 45°135°90° up-45°-135°0°front180°back — 10000 Hz — 12500 Hz — 16000 Hz-90° down45°135°90° up-45°-135°0°front180°back — 4000 Hz — 5000 Hz — 6300 Hz — 8000 Hz-90° down45°135°90° up-45°-135°0°front 180°back — 1600 Hz — 2000 Hz — 2500 Hz — 3150 Hz-90° down45°135°90° up-45°-135°0°front 180°backI SERIES Point Source 600IP6-1152/64MEDIUM POWER 15-INCH TWO-WAY60° x 40° INSTALLATION LOUDSPEAKERCommunity Professional Loudspeakers333 East Fifth Street, Chester, PA 19013-4511 USA Phone (610) 876-3400 • Fax (610) •*********************CAUTION: Installation of loudspeaker s should only be performed by trained and qualified personnel.

Problem 1: No sound or distorted sound from one loudspeaker in a pair (or set) Connect the dead/distorting loudspeaker to a different amplifier channel (one that had a functioning loudspeaker connected to it). If it functions normally, the problem is not loudspeaker-related. If the loudspeaker still makes no sound or sounds distorted, a wire may have become loose or disconnected, the network (also known as a crossover) may be defective, the drivers (woofer, tweeter, etc.) may be defective or, in very rare cases, all may be defective.
