但关于马兰于PM-16功放,本人翻查了大量的音响刊物及上网查讯,却只有大量关于马兰士pm-14及pm-17的评论。
现请主持点评马兰士pm-16功放的声色,特点及与pm-14和pm-17有何不同？达到何等级别？另请推荐一台中低价位的LP唱盘。
望主持先生能抽空解答我的难题。
答：建议用PM-16推奥地利的维也纳的海顿扬声器，此箱的价格约8800元，或者选丹麦的SEK的S11，此箱价格约14800元。
这样的搭配比较合理，声音的表现也比较完美。
LP转盘可以考虑下美国的音乐教堂的唱盘。
问：请问BRYSTON 7Bst 和7Bst Pro ，BP-25前级的价钱，有现货吗？答：这套器材全部大概7万元左右，具体要与代理那边联系下才知道有没有现货，他们的电话是，。
问：本人想查询英国ATC音箱的中国(广州市)代理商是谁? 答：他们的代理的电话是，问：我于今年购得森海塞尔HD580耳机一副，望推荐耳放（国产，进口）及讯号线，现看中科颂U5及VHL 102D，不知此番搭配是否妥当。
另外，不知国产的滤波器效果如何望指点一二，平日喜欢听人声和小的作品，如钢琴、小号的小段，听感要求细节丰富，富有音乐感和层次感，对低频要求不高答：耳放可以用英国瑟顿SUGDEN或者意大利的BLUE NOTE的产品。

Registrationenables us to keep you posted onour latest advancements, andhelps us to better understand ourcustomers and build productsthat meet their needs andexpectations.3CHAPTER 1 –LEGACY:THE HISTORICAL DEVELOPMENT OF THE JBL PROJECT LOUDSPEAKERSOf those few who seek perfection in sound reproduction, only a handful have actually achieved it. The price is always high. It is a rare occur-rence indeed when an individual or group is able to triumph over the constraints of economic and tech-nological reality even once.At JBL, this has happened eight times. In each case, its engineers were told to build the speaker sys-tem they had always wanted to build. Whatever resources were required would be made available. Thus began an ongoing investiga-tion into new frontiers of sound reproduction, beginning in 1950, and continuing to the present day. The products that have resulted from this venture are now known as the JBL Project loudspeakers. Each represents the absolute peak of every technological, material and engineering innovation availableat that time, combined into a single system. They are Hartsfield, Paragon, Everest, K2 S9500/7500 and K2 S5500.The newest models are the K2 S5800 and K2 S9800. Although differing in performance details and physical attributes, each of the Project loudspeakers has shared a common objective: to ele-vate sound reproduction to levels defined only by the limitations of existing materials and technology. And despite a spread of nearly 50 years, all Project loudspeakers have shared many common features – testimony to their foundation on the technology and manufacturing techniques upon which JBL was built.DEFINING THE PROJECTCONCEPTThe Hartsfield began a tradition atJBL that continues today. First, engi-neer a product as close to perfectionas possible. When it reaches thatlevel, it is time to make it better.In 1954, the Hartsfield was signifi-cant in that it represented not newtechnology, but rather a new levelof the all-technical manufacturingapproach pioneered by James B.Lansing some 20 years before it.Like its Project series successors,it was a high-efficiency systemincorporating compression drivertechnology, one combining thequalities of high output, low distor-tion, exceptional stereo imagingand fatigue-free listening. Mostimportant, it was the first consumer-available listening system to do so.In this respect, Project K2 S5800is at once the most advanced andsophisticated loudspeaker in theworld today (save for the ProjectK2S9800) and a speaker whosetechnology is deeply rooted in morethan 50 years of tradition. JBL’spresident in 1954, William Thomas,described the Hartsfield as “...thespeaker system we have alwayswanted to build...the finest compo-nents ever made available to seri-ous listeners.”He went on to describe the processbehind his creation: “Most peoplewho own and appreciate fine soundreproduction equipment look for-ward to the day when they will beable to assemble a system withoutlimitation in just exactly the waythey think it should be done.“Periodically, a manufacturer getsthis same feeling....The science ofacoustics has provided us withbasic principles – available to all forachieving precision reproduction.It is only a matter of incorporatingthese methods into a system design,and then taking every bit of troublenecessary to build a system pre-cisely to the design. It isn't easy, butthat’s the way it is done.”The Ranger-Paragon,JBL’s secondProject system, was the first seri-ous attempt at a reflecting speakersystem, and broke new ground inthe concept of stereo imaging.Essentially two independent full-range speaker systems installed ina handsome curved cabinet nearly9 feet long, the Paragon’s enclosurewas treated as an extension of itstransducers. In essence, the systemhad its own “built-in acoustics.” Inmany respects the Paragon antici-pated loudspeaker developmentsthat would occur years – and evendecades – later.For nearly 30 years, the Paragonremained the most acousticallyviable sound system for the home.Today, along with the Hartsfield,it is still the most sought-afterspeaker in the world.In 1986, JBL introduced a newProject system that retained theParagon’s overall sense of musicalitywhile upgrading its character byincorporating three decades’ worthof continuous development in everyfacet of its design. Its name reflectedthe pinnacle of achievement it rep-resented: Project Everest.For the first time, the rest of thesound reproduction chain – and notthe loudspeaker or its transducers –would impose limits on overall sys-tem performance. Like the Paragonand Hartsfield, Project Everestwas built around compressiondriver technology and addresseda more refined stereo image thanwas previously consideredtechnically feasible.45In order to re-create the extremely high dynamic range provided by today’s audio sources, a new low-frequency transducer was used, incorporating a ferrite magnet, 3-inch edge-wound voice coil, and an Aquaplas™-coated 12-inch cone made of Kevlar®composite, a mixture of Kevlar fiber and pulp material that provides increased rigidity. An EPDM rubber sur-round was chosen for both its flexibility and long life. The Symmetrical Field Geometry™(SFG) magnetic structure mini-mizes second harmonic distortion by providing a uniform flux field that avoids uneven cone move-ment. The rigid cast-aluminum frame is also designed to mini-mize distortion, as aluminum has no effect on the magnetic field. Extensive computer-aided engi-neering and design effort made to develop the optimized port tuning employed in Project K2 S5800has resulted in a significant advance in the concept of state-of-the-art bass reproduction. This proprietary align-ment method offers the best damp-ing characteristics and provides extremely fast alignment, eliminat-ing the typical “bass-reflex” sound of a ported system.All three transducers are built using the most advanced materials and precision manufacturing tech-niques refined from renowned JBL professional sound systems.High power-handling capability results in no limitations on the types of source material. Project K2 S5800 has very high input sensitivity;even a relatively small high-end amplifier can provide full dynamic range without compression.Despite its power and sophistica-tion, Project K2 S5800is a marriage of tradition and technology. It reflects the design, engineering and manufacturing expertise derived and refined through nearly six decades of experience that are the exclusive province of one loudspeaker builder: JBL.678910CHAPTER 5 – AMPLIFIER RECOMMENDATIONSNo single type of amplifier is specified for use with the Project K2 S5800 system. The speakers are highly efficient and will operate adequately with an amplifier or receiver of 70–100 watts. However, the transient response and audio definition of a high-end system such as Project K2 S5800 will pick up all inefficiencies and distortion in an amplifier system. For full-range operation, the Project K2 S5800system can be used with an amplifier/receiver of as little as 30 watts. Amplifiers/ receivers of 100–300 wattswill ensure optimum system performance.There is no effective limit to the power handling capabilities of the Project K2 S5800 loudspeakers when driven by consumer audio amplifiers. No damage will occur when used with high-powered components. Source impedance is an important criterion in selecting an appropriate unit; the selected amplifier(s) should have a very high current capacity and must be capable of driving a low impedance load.For bi-wiring or bi-amplificationapplications, four identical ampli-fiers or two dual-channel units maybe used, although specialized low-frequency and high-frequencyamplifiers offer clear advantages.(If four amplifier channels are used,the high-frequency amplifier maybe up to 6dB less powerful thanthe low-frequency amplifier. Dueto the power versus frequencydistribution of the music, the low-frequency section requires approxi-mately four times the power of thehigh-frequency section.)Project K2 S5800specialist dealerscan recommend amplification tobest suit individual needs. In allcases, the left and right amplifiersfor each section must be identical.Make sure that the input sensitivityof the two amplifiers is equal or thatinput level controls are provided tomaintain the proper low to mid/highbalance. If two identical stereoamplifiers are chosen, each amplifiermay be located near a loudspeakerand drive low-frequency and high-frequency sections through shortwire runs.111213¡Bias Battery:The bias battery supplies constant DC bias to the crossover capacitors, eliminating crossover distortion at zero electric potential. Replace the test battery supplied with your system with a9-volt, 006P rectangular battery as soon as possible. Thereafter, although the speaker will function without the battery, JBL recommends that you replace the battery every two years for best performance. Access the battery by unscrewing the cover. Make sure to observe proper polarity when installing the replace-ment battery.™Network Mode Switch:This switch should be left in the “Normal/Bi-Wire” position unless you are connecting the speaker in a bi-amp configuration using two power amplifiers and an external electronic crossover. Access the switch by unscrewing the battery cover. The switch may be adjusted using a flat-head screwdriver.£HF Trim Switch:This switchallows you to adjust the output of thehigh-frequency transducers to com-pensate for the acoustics of yourroom. The +1dB position increasesthe output, the 0dB position is a flat-level position, and the –1dB positiondecreases the output. Each positionwill affect the tonal balance over awide frequency spectrum. Experimentby placing the switch in each positionwhile listening to familiar programmaterial and choose the position thatsuits your room acoustics and listen-ing preferences. You may find thatafter a few months, once the trans-ducers have settled in, that anotheradjustment is necessary. This isnormal. Access the switch byunscrewing the battery cover. Theswitch may be adjusted using aflathead screwdriver.¢Mid/High-Frequency InputTerminals:For bi-wire or bi-ampconfigurations, connect the speakerwires for the mid- and high-frequencyranges to these terminals.∞Shorting Bars:Leave the short-ing bars in place only if you are usingthe passive single-wire connectionoption described on page 15.Otherwise, remove the bars to pre-vent possible damage to the speakersor your electronics.§Low-Frequency InputTerminals:For bi-wire or bi-ampconfigurations, connect the speakerwires for the low-frequency range tothese terminals.14Figure 9. K2 S5800controls and connections.1516CHAPTER 8 – PROJECT K2 S5800CARE AND MAINTENANCEThe Project K2 S5800loudspeaker system is sprayed in a poly-urethane finish and requires no maintenance other than an occa-sional dusting with a soft, dry, lint-free cotton cloth.The horns may also be wiped with a soft cloth. Treat the surface very carefully to avoid scratching the finish. To remove fingerprints and smudges, apply a small amount of ammonia-free window cleaner to the cloth and gently clean the surface.Never use any abrasive cleaners or chemicals to clean the enclo-sure. If the enclosure becomes perceptibly scratched or other-wise damaged, consult a qualified furniture repair shop.The grilles should never be washed in water, which might cause discoloration or sagging. The grilles may be cleaned using a vacuum cleaner with the suc-tion set extremely low.Should you wish to clean thewoofer surfaces, use a soft, drypaint brush to carefully sweep thedust away. Never use a damp cloth.JBL’s unique Charge-CoupledLinear Definition system is usedfor the crossover network, inwhich a direct (DC) bias current isconstantly applied to the capaci-tors in the network circuit to acti-vate the elements, eliminatingcrossover distortion at zero elec-tric potential.The battery has a life of about twoyears. Even if the battery voltagedrops, the network will continueto function. However, in order tomaintain superior sound quality,we recommend that you test andchange the battery once a year.Note that the battery may leakand damage the holder and otherparts if it is left in the speaker for along period after exceeding thesuggested duration.To access the battery, unscrewthe battery cover at the top ofthe terminal board and remove it.Always use a 9V, rectangular006P-type battery and install itwith the proper polarity.The battery included in theshipped system is for testingpurposes only. We recommendthat you replace it as soon aspossible.All wiring connections should beinspected and cleaned or remadeperiodically. The frequency ofmaintenance depends on the met-als involved in the connections,atmospheric conditions, and otherfactors.

This overhead view shows a typical home theater system arrangement.CouchLeft Front ChannelRight Front ChannelJBL Subwoofer (optional)Figure 1.THANK YOU FOR CHOOSING JBL2PLACEMENTSTEREOBefore deciding where to place your speakers, survey your room and think about placement, keeping the following points in mind, and using Figure 1,on previous page, as a guide:•For best results, place the speakers 6'–8' apart.•When installing in the wall, position each speaker so that the tweeter isas close to ear level as practical.•Refer to “Home Theater” below if you also plan to use the speakers ina home theater system.HOME THEATERFor front-channel use, place one speaker on the left and another on theright along either side of the television.A center channel speaker should go directly above or below the television and can be an in-wall, in-ceiling or freestanding center channel.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.In 6- or 7-channel configurations, place the rear channel(s) behind the listening position, as shown in Figure 3.NOTE:A JBL powered subwoofer will add impact and realism to bothmusic and film soundtracks. Contact your JBL dealer for recommendations on subwoofer models for your application.Proper placement of the speakers is an important step in obtaining the most realistic soundstage possible. These recommendations are for the optimal placement of the loudspeakers. Use these placement recommendations asa guide. Slight variations will not diminish your listening pleasure.INSTALLATIONThe Studio™L Series in-wall and in-ceiling speakers were designed to be easily installed. However, if you are unable to clearly and fully understand and follow the instructions in this manual, or if you are unsure of your ability to properly install these loudspeakers, please contact your dealer or a qualified installer. TOOLS NEEDEDPhillips #2 screwdriver(Do not use a powered screwdriverof any kind)Measuring tape Utility knifePencilCarpenter’s level Awl CONNECTION TIPSSPEAKER CONNECTIONSWire Length Recommended SizeUp to 100 ft.16-gaugeGreater than 100 ft.12-gaugeTURN OFF ALL POWERBefore completing the installation, you must connect your speakers to your system. First, turn off all audio-system power. Use high-quality speaker wireto make your connections. Use at least #16-gauge speaker wire with polarity coding. Heavier gauge wire is recommended for larger distances. Consult the chart above or your dealer for recommendations. The side of the wire with a ridge or other coding is usually considered positive (+) polarity. 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) terminalsin the same way.IMPORTANT!Do not reverse polarities (i.e., + to – , or – to +) when making connections. Doing so will cause poor imaging and diminished bass response. Be certain that positive and negative wire strands are completely isolated to avoid short circuits that may damage your equipment.Figure 4.3EXISTING CONSTRUCTION L226C,L228C,LS326C,LS328C1.

Make sure all four locking tabs are properly positioned against the locking tab stops that arelocated on the speaker frame (see Figure 6 below). After confirming this, carefully place the frame assembly in the wall and confirm that there is no more than 1/8-inch play between the frame and the wall cutout. After positioning the speaker in the mounting location,back each screw out one full turn (turn counterclockwise).8. Attach the metal grille and logo, if desired.Figure 6.NEW CONSTRUCTIONIf you wish to preinstall a rough-in frame before the drywall is installed, you will need to purchase the correct rough-in-frame kit for your model:Speaker Model Rough-In-Frame KitL226W, LS326W RIF 6L226C, LS326C RIF 6CSL228C, LS328C RIF 8CDetailed installation instructions are supplied with the rough-in kit. PAINTING THE SPEAKER FRAME AND GRILLEStudio L in-wall and in-ceiling loudspeakers can be painted to match any décor. If you wish to change their color, the satin finish on the grille and frame will function as a primer coat. Before painting, install the paint shield (inner section of template in the assembly kit) securely into the recess in the baffle.This will protect the speaker components and baffle from paint residue. Use a high-quality spray paint, and apply a thin coat of color. Be certain the grille perforations remain free of paint. Filling them with paint will diminish the sound quality.NOTE:Gently remove the acoustical foam blanket from the grille before paint-ing. Reattach the blanket after the paint has dried.OPERATIONSURROUND MODESWhen using the system in a Dolby®Digital or DTS®home theater system,make sure all speakers are set to “Small.”When using the Studio L in-wall and in-ceiling speakers in a Dolby Pro Logic®home theater system, make sure the receiver’s center channel mode is set to “Normal.”Some Dolby Digital-equipped receivers/processors offer different setupoptions for each source or surround mode: e.g., CD-stereo, videotape, Dolby or Pro Logic. In each case, follow your equipment’s instructions to ensure that the subwoofer (if you have one) output is turned on and that the speakers are set to “Small” in each mode.6SPECIFICATIONSStudio L L226W L226C L228CFrequency Range (–6dB)30Hz – 20kHz30Hz – 20kHz28Hz – 20kHzRecommended10 – 125 Watts10 – 125 Watts10 – 135 WattsAmplifier Power RangeSensitivity89dB89dB90dB(2.83V @1meter)Nominal Impedance8Ohms8 Ohms8 OhmsCrossover Frequency3,000Hz;2,500Hz; 2,500Hz;24dB/Octave18dB/Octave18dB/OctaveLow-Frequency Driver6-1/2" (165mm)6-1/2" (165mm)8" (200mm)Aluminum cone Aluminum cone Aluminum coneHigh-Frequency Driver1" (25mm)1" (25mm)1"(25mm)Titanium-laminate Titanium-laminate Titanium-laminateExternal Dimensions 8-1/2" x 11"Diameter: 9-3/16"Diameter: 10-7/8"(W x H)(216mm x 280mm)(233mm)(276mm)Mounting Cutout Size 7" x 9-1/2"Diameter: 7-7/8"Diameter: 9-1/2"(W x H)(178mm x 241mm)(200mm)(241mm)Mounting Depth3-9/16" (90mm)4-1/8" (104mm)4-5/8" (117mm)Weight (Net) 3.5 lb (1.6kg) 3.5 lb (1.6kg) 5.8 lb (2.6kg)Studio L LS326W LS326C LS328CFrequency Range (–6dB)30Hz – 30kHz30Hz – 30kHz28Hz – 30kHzRecommended10 – 135 Watts10 – 135 Watts10 – 150 WattsAmplifier Power RangeSensitivity89dB89dB90dB(2.83V @1meter)Nominal Impedance8Ohms8 Ohms/channel8 OhmsCrossover Frequency3,000Hz;2,500Hz;2,500Hz;24dB/Octave18dB/Octave18dB/OctaveLow-Frequency Driver6-1/2" (165mm)6-1/2" (165mm)8" (200mm)Aluminum cone Aluminum cone Aluminum coneHigh-Frequency Driver1" (25mm)1" (25mm)1"(25mm)Titanium Titanium TitaniumExternal Dimensions 8-1/2" x 11"Diameter: 9-3/16"Diameter: 10-7/8"(W x H)(216mm x 280mm)(233mm)(276mm)Mounting Cutout Size 7" x 9-1/2"Diameter: 7-7/8"Diameter: 9-1/2"(W x H)(178mm x 241mm)(200mm)(241mm)Mounting Depth3-9/16" (90mm)4-1/8" (104mm)4-5/8" (117mm)Weight (Net) 3.5 lb (1.6kg) 3.5 lb (1.6kg) 5.8 lb (2.6kg)All features and specifications are subject to change without notice.7owner’s manual are in compliance with technical standards:Laurent Rault。
JBL SSW-2 高性能双12英寸扬声器说明书
MANUAL DEL PROPIETARIOJBL ® SSW-2Subwoofer pasivo dual de 12” de alto rendimiento2GRACIAS POR ELEGIR JBL®Durante más de 70 años, JBL se ha implicado en todos los aspectos de la grabación y reproducción de música y películas, desde conciertos en directo hasta las grabaciones que puedes escuchar en casa, el coche o el despacho.Confiamos en que el sistema JBL que has elegido proporcione todas las notas de diversión que esperas y que cuando pienses en comprar otros equipos de audio para el hogar, automóvil o despacho vuelvas a elegir, una vez más, los productos JBL.Dedica unos instantes a registrar tu producto en el sitio web en . Esto nos permitirá mantenerte informado de nuestros avances más recientes y conocer a nuestros clientes y ofrecerles productos a la medida de sus necesidades y expectativas.Todas las funciones y especificaciones del producto están sujetos a cambios sin previo aviso.INCLUIDO1. Subwoofer2. Rejilla3. Manual del propietarioCOLOCACIÓNAl utilizar subwoofers en un espacio delimitado como una sala normal de cine en casa, las reflexiones, las ondas estacionarias y los absorbentes resonantes que haya en la sala generan picos y valles en la respuesta de bajos que varían de forma importante en función de la ubicación de los oyentes en la sala. Un oyente sentado en un lugar puede escuchar un exceso de bajos generados por un pico de respuesta en esa ubicación, mientras otro oyente a un metro de distancia puede escuchar mucho menos a causa de la presencia de un valle en su lugar.Las ubicaciones de los subwoofers dentro de la sala (junto con las dimensiones de esta) también tienen un efecto importante en la generación de estos picos y valles en la respuesta de bajos. La colocación cuidadosa de los subwoofers no puede, por sí sola, compensar todos los picos y valles de la respuesta en una sala, pero sí puede eliminar o reducir de forma importante los valles más importantes.Es importante reducir los valles en la respuesta por toda la sala en la medida de lo posible colocando los subwoofers correctamente, ya que no es posible utilizar la ecualización para compensar estas variaciones importantes en la respuesta. Por ejemplo, utilizar la ecualización para tratar de compensar un valle de 13 dB en la respuesta exige al amplificador aportar 20 veces la potencia a la frecuencia en cuestión. Esto puede suponer que se supere rápidamente la capacidad del amplificador, lo cual da lugar a cortes que degradan apreciablemente la calidad del sonido.Casi en cualquier sala, colocar los subwoofers en las esquinas produce los valles menos pronunciados y los picos más elevados en la respuesta de bajos.Recomendamos encarecidamente instalar más de un subwoofer independientemente del tamaño de la sala. Con un solo subwoofer se obtiene la distribución menos homogénea de bajos en la sala. Al utilizar más de un subwoofer, es posible cancelar algunos de los modos de la sala en distintas ubicaciones de escucha, lo cual proporciona una calidad de sonido más homogénea a bajas frecuencia en3 toda el área de escucha. A menudo no es posible ubicar un solo subwoofer sin que queden grandes valles en la respuesta, que no se pueden corregir mediante la ecualización. Casi siempre, utilizar dos o más subwoofers bien colocados sirve para eliminar estos valles en la respuesta.Puesto que la construcción de las paredes casi nunca es perfectamente idéntica en las paredes opuestas, en la práctica, las soluciones basadas en fórmulas como la colocación de los subwoofers en los puntos de 1/4 raramente funcionan. La mejor solución es realizar mediciones de alta resolución en el área principal de escucha mientras se experimenta con la colocación de los altavoces.Colocar un subwoofer en la posición de escucha y medirlo desde las posibles posiciones de instalación disponibles en la sala, utilizando la reciprocidad acústica, puede ayudar a encontrar más rápidamente las mejores posiciones. Este tipo de mediciones desde las mejores posiciones posibles genera los resultados con el número y el valor mínimo de picos y valles en la respuesta.COLOCACIÓN DE UN SOLO SUBWOOFERCOLOCACIÓN DE DOS SUBWOOFERSLa colocación de dos subwoofers se determina en función de la organización de los asientos de escucha de la sala.Salas con una sola fila de asientos Salas con más de una fila de asientosCOLOCACIÓN DE CUATRO SUBWOOFERSCONEXIONESLos altavoces y la electrónica tienen terminales (+) y (–) correspondientes. La mayoría de fabricantes de altavoces y electrónica, incluidoJBL, utilizan el color rojo para el terminal (+) y el color negro para el terminal (–). Es importante conectar ambos terminales de formaidéntica: el conector (+) del altavoz con el (+) del amplificador y el conector (–) del altavoz con el (–) del amplificador. Si se conectan loscables “fuera de fase”, se obtiene un sonido pobre, con bajos débiles y una mala reproducción espacial en estéreo. Con la llegada de lossistemas de sonido envolventes multicanal, la conexión de todos los altavoces del sistema con la polaridad correcta sigue siendo igual deimportante para conservar el ambiente y la direccionalidad correctos del material del programa.Si se utilizan dos subwoofers SSW-2, los cables de ambos deben tener la misma longitud. Si la respuesta de bajos parece reducida, esposible que haya un problema de fase y que las ondas sonoras de ambos subwoofers se estén cancelando entre sí. Si la respuesta de bajosparece baja, prueba a invertir la polaridad de uno de los subwoofers, es decir, conectar el terminal (+) del amplificador al terminal (–) delaltavoz y el terminal (–) del amplificador al terminal (+) del altavoz.Para utilizar los terminales de altavoz con poste atornillado de la copa de terminales situada en la parte trasera del subwoofer SSW-2,desatornilla la perilla de color hasta que puedas ver, debajo de la perilla, el orificio que atraviesa el poste por el centro. Inserta el extremodel cable pelado por este orificio y, a continuación, vuelve a apretar la perilla hasta que la conexión esté bien sujeta. Si utilizas conectoresde pala, puedes deslizarlos alrededor del poste antes de apretar la perilla. El orificio del centro de cada perilla sirve para utilizar conectoresde tipo banana. Asegúrate de respetar la polaridad correcta. El cable del terminal negativo (–) del amplificador se debe conectar alterminal negativo (–) o negro de la copa de terminales y el terminal positivo (+) del amplificador se debe conectar al terminal positivo (+)o rojo de la copa de terminales.Puesto que el SSW-2 es un altavoz pasivo, solo dispone de conexiones de nivel de altavoz. El subwoofer SSW-2 está diseñadoespecíficamente para usarlo con amplificadores JBL® Synthesis SDA. Se ha optimizado para ofrecer la mejor dinámica yrespuesta en frecuencias utilizando el amplificador JBL SDA-4600, que se ha diseñado específicamente para impulsar laimpedancia de carga reactiva emblemática del SSW-2. El SSW-2 es capaz de funcionar con dos canales de SDA-4600 en modopuenteado.Conecta el receptor principal o la salida de subwoofer de nivel de línea del procesador a la entrada de nivel de línea del amplificadordel subwoofer.Si utilizas dos o más subwoofers, utiliza el número correcto de canales de amplificador (pueden ser amplificadores monobloqueoo multicanal), cada uno de ellos conectado a la salida adecuada del procesador o el receptor. A continuación, conecta losterminales positivo y negativo de cada canal del amplificador a un solo sistema de subwoofer SSW-2.45Longitud del cable Tamaño recomendadoHasta 9 m.Calibre 14 (grosor mínimo)Más de 9 m.Calibre 12 (grosor mínimo)SOLUCIÓN DE PROBLEMASSíntoma SoluciónSi no sale ningún sonido de ningún altavoz • Comprueba que el receptor/amplificador esté encendido y se esté reproduciendo alguna fuente.• Comprueba todos los cables y las conexiones entre el receptor/ amplificador y los altavoces.

JBL,S4700永远的号角
JBL,S4700永远的号角前言号角单体，扬声器中的永恒!诞生于20世纪20年代，早期用于影剧院扩声，之后逐步进入到Hi-Fi民用音响领域。
曾经的Western Electric、Klipsch(杰士)、Altec Lansing及后来的JBL等是最早研制号角的公司，一些古董级号角音箱如AltecA5、604、JBL Olympus 等至今被资深发烧友垂青和收藏。
之所以如此，皆因号角特有的扩声作用，它的驱动单体设计可以使扬声器效率提升达数十倍，使其在很小的振幅下发出相当高的声压，从而抑制失真，获得更加线性的频率响应。
从发声原理上讲，号角不存在锥盆单体的能量损耗，具有优良的瞬态特性和阻尼特性。
随着开口面积的增大，频率下限也会相应降低，开口较大的号角低频可平直下到500Hz以至300Hz，只要加只大口径低音单体，就可满足全频需求。
实际听音时，我们可以明显感受到号角的声音直接、声场开阔、定位清晰、空间感强，带给我们一个更真实的音乐现场。
既然号角有着这样好的优点，那么为什么多年来它都没有成为市场的主流呢?其实这与它的高成本、指向性增益、离轴响应、空气非线性失真等问题没有得到真正解决有很大关系。
如它的高频尖锐、缺乏水分始终是很大的缺憾，JBL创始人Jams B Lansing 的多件经典作品在大动态音乐时运用自如，但在高低频的两端延伸、中频粗声上却不甚如人意。
即便是在低音前端采用了前加载号角设计的Klipsch(杰士)Lascala，由于受限体积，仍然在很多方面缺少较好的表现。
直到后来的声音趋于现代化的JBL 4344才在设计上有了很大改进，虽然少了些早期号角的奇特之处，但声音的平衡性好上许多。
尽管如此，很多音响发烧友，特别是号角死党，都认为直到JBL K2的出现，才真正宣布号角音箱终于实现完美无缺的平衡度和均匀的频率响应。
其中最具代表性的就是S9800SE，气势恢宏壮观的临场感和浑然一体的全频让你完全享受了最美的音乐。
JBL SSW-2 双低音炮用户手册说明书
用户手册JBL ® SSW-2高性能双 12”无源低音炮2感谢您选择 JBL®70 年来，JBL 一直参与音乐和电影录制及重现的方方面面，包括现场表演，监听室内、车辆或办公室播放的录音等等。
我们相信，您所选择的这款 JBL Synthesis 扬声器能提供您所期待的每一个娱乐细节，并且当您考虑为您的家庭、汽车或办公室购买其他音频设备时，您一定会再次选择 JBL 。
请花费少许时间，访问我们的网站 并注册您的产品。
这将帮助我们更好地了解您的需求，为您提供最新的资讯，从而提供能够满足您期待的产品和服务。
所有功能和规格可能随时变更，恕不另行通知。
1. 低音炮2. 网罩3. 用户手册摆放普通家庭影院房间的空间都比较有限，在其中使用低音炮时，房间中产生的回声、驻波和共振都会导致低音响应出现峰值和谷值，至于听众所能听到的低音强弱，则很大程度上取决于他们在房间的就坐位置：一位听众可能会因为所在位置处于响应峰值而听到过量低音，而另一位听众即使只是在几英尺距离之外，但却因为所在位置处于响应谷值而只能够听到极少的低音。
低音炮在房间中的位置（以及房间的大小）也会对这些低音响应峰值和谷值的形成产生重要影响。
单靠谨慎选择低音炮的摆放位置，并不足以补偿整个房间内的所有低音响应峰值和谷值，但是，这能够消除或显著降低最大响应谷值。
由于均衡设置并不足以补偿大幅度的响应谷值，因此通过选择适合的低音炮摆放位置，能够尽可能降低房间内的响应谷值，这一点至关重要。
例如，使用均衡设置来尝试补偿 13dB 的响应谷值，这就要求低音炮的功放必须能够在该频率下将功率提高二十倍。
这很快就会超过低音炮功放的处理能力并造成削波，使音质受到严重影响。
在大多数房间中，将低音炮摆放在角落产生大幅度低音响应谷值的情况最少，并能够产生最大的低音响应峰值。
我们强烈建议您暂且忽略房间大小，而安装多个低音炮。
如果只安装一个低音炮，整个房间中低音表现的统一性也只能达到最低水平。
