DSPPA公共广播工程手册模板
DSPPA公共广播工程手册模板DSPPA公共广播工程手册广州声雅音响器材公司工程部编译一、公共广播工程设计的一般顺序这里所说的公共广播杲指有线传输的声音广播，一般见于公共场馆.大厦.小区内部，供背景音乐广播、寻呼广播以及强行插入的灾害性广播使用。
这一类公共广播工程的设计，一般按下列顺序逬行：1、首先应考虑广播扬声器的选用.配置2、广播功放的选用3、广播分区4、广播系统的建构本手册依据DSPPA公共广播系列的资料进行编译。
二、广播扬声器的选用和配置1、广播扬声器的选用原则上应视环境选用不同品种规格的广播扬声器。
例如，在有天花板吊顶的室内，宜用嵌入式的、无后罩的天花扬声器。
如DSP-501、DSP-701. DSP-802系列。
这类扬声器结构简单，价钱相对便宜,又便于施工。
主要缺点是没有后罩，易被昆虫、鼠类啮咬。
在仅有框架吊顶而无天花板的室内（如开架式商场），宜用吊装式球型音箱（DSP-107）或有后罩的天花扬声器（如DSP-901〜902系列）o由于天花板相当于一块无限大的障板，因此在有天花板的条件下使用无后罩的扬声器也不会引起声短路。
而没有天花板时情况就大不相同，如果仍用无后罩的天花扬声器，效果合很差。
这时原则上应使用吊装音箱。
但若嫌投资大，也可用有后罩的天花扬声器。
有后罩天花扬声器的后罩不但有一般的机械防护作用，而且在—定程度上起到防止声短路的作用。
在无吊顶的室内（例如地下停车场），则宜选用壁挂式扬声器或室内音2柱。
前者如DSP-106. DSP-207.系列；后者如DSP-103~403、DSP-109〜609 系列。
在室外，宜选用室外音柱或号角。
前者如DSP-105〜405、DSP- 108〜408系列；后者如DSP-CH〜PH系列。
这类音柱和号角不但有防雨功能，而且音量较大。
由于室外环境空旷,没有混响效应，选择音量较大的品种是必须的。
在园林、草地，宜选用草地音箱。
如DSP-3601~3602系列。

Specifically designed tomaintain a consistent tonal characteristic across the entire family in ceiling, surface, and pendant applications, theAcousticDesign series allows integrators seamless transitions within blended installations.The AD-C4T features a high quality 4.5" weather treated paper cone woofer with a 1" voice coil and a .75" aluminum dome tweeter which is positioned on a DMT waveguide.DMT (Directivity Matched Transition™) is QSC’s design philosophy where the high frequency waveguide is matched to the natural conical behavior of the woofer at the crossover point. The result is a coherent transition between transducers with improved off-axis power response for consistent 150° conical DMT coverage. The accurate frequency response of the AD-C4T is maintained even in 70/100V applications by use of a low-loss, low-saturation 30-watt transformer with selectable taps, including 16Ω bypass, using a rotary selector located under thesnap-fit magnetically attached powder coat steel grille.To retain lasting good looks, the rugged ABS baffle is further protected by using UV inhibitors that prevent discoloration and by a powder coated steel back can. Themagnetic grille features a stick-on logo that can be removed blemish-free for installations where branding is not permitted.Installers will appreciate the 3x doublestepped, long travel dog-ear blind mounting system, which captures from 0" - 2.25" of ceiling thickness. A captured Phillips screw provides access to the removable conduit cover plate; also available as an accessory, as is a separate mud-ring for pre-install wiring. A locking 4-pole Euro-block connector that can accept four 18AWG pairs eliminates the termination hassles of star topology wiring designs.Intrinsic Correction™ voicings that optimize performance and speed the install process are easily deployed via Q-SYS networked audio processing platforms, including CXD power amplifiers, as part of a complete QSC systems solution.The AD-C4T is available in QSC standard black (RAL 9011) or white (RAL 9010) and may be painted to match any decor.For your system integration needs,complete EASE, CF2, CAD, and BIM filesare available for download at .1675 MacArthur Boulevard • Costa Mesa, CA 92626 • Ph: 800/854-4079 or 714/957-7100 • Fax: 714/754-6174please recycle© 2016 QSC, LLC all rights reserved.

Consult a licensed instal-lation professional if you are uncertain about any mounting issues.The AD-C81Tw models feature a 8” low frequency (LF) driver in a ported enclosed.The AD-C81Tw is equipped with an audio transformer suitable for 70V and 100V dis-tributed systems, as well as a tap-selector switch which can bypass the transformerWhat’s IncludedYour ceiling loudspeaker box contains:- the loudspeaker cabinet- the protective grill assembly- two support brackets for suspended ceiling installations- C-ring bracket for suspended ceilings and other ceiling reinforcing applications- Self-tapping screws(M4.2 X 1.4 X 10mm) for securing the C-ring-to-support brackets- grill clip used for clipping the plastic grill retaining lines together- phoenix connector assembly for connecting signal and daisy-chaining- paint shield- grille clothInstallation OptionsThe AcousticDesign in-ceiling loudspeakers can be mounted in suspended ceilings, as well as non-suspended types. We recommend an installation professional be consulted for safety assurance, quality installation, and optimum acoustic performance.For suspended ceiling applications, the suspended ceiling support brackets must be used with the C-ring bracket. The suspended ceiling support brackets are designed to accommodate 24” or 600 mm t-channel grid spacing. The brackets do not attach to the t-channel; the angled “V” bend sits over the t-channel and will catch the t-channel in the event of a tile failure or fall-out.For other ceiling types, the C-ring bracket can be used to reinforce the mounting surface. If the ceiling is suitably strong, the loud-speaker can be secured in the cutout hole without additional reinforcement.Audio connections are made directly to the ceramic teiminal block or by using terminal block type connectors. Two sets of terminals are provided; one set for the signal connection and another for pass-through (or daisy chain) connection to other loudspeakers on the same distribution circuit.Two safety features are provided, an enclosure-retaining safety tab and a grill-retaining safety tether. The enclosure tab is a metal tab near or on top of the enclosure suitable for securing the loudspeaker to building framing; this provides maximum safety in the event the ceiling structure fails for any reason. The grill’s safety tether prevents the grill from failling in the event it should vibrate loose.Other Recommendations and Important Information•Grill removal: The grill can be removed by carefully prying around its outer edge or inserting a small, metal pin or hook into the grill’s openings and pulling evenly around its perimeter.•If rattles or buzzing is heard during operation, it may be necessary to put vibration dampening material between the support rails and the ceiling tiles and/or t-channels.•The support rails have holes along their usable length to attach the C-ring bracket. This allows for the cutout to be placed in many positions along the ceiling tile width.1-the ceiling surface.2- Cut the mounting hole. Use a sharp tool to avoid stressing or cracking the mount-ing surface.3- Pull the wires through the hole.4- Pass the two suspended ceiling support brackets through the hole and place as are not required.5- Pass the C-ring bracket through the hole. Slide the cutout slot into the hole first, and then rotate the bracket so it passes through the hole. Be sure the wires pass through the ring.6-brackets using the screws provided. If installing in a non-suspended ceiling applica-tion, skip this step.7- Loosen the connection cover plate retaining screw and swing the cover open. Install an fitting into the hole provided on the cover plate.8- Temporarily support the enclosure so the wires may be passed through the enclo-sure top with enough slack to prepare and terminate the wires.9- Locate the terminal block connectors included with the loudspeaker. Loosen the wire retaining screws fully.10- Strip the wire ends approximately 10 mm (0.4”) and insert each wire into its proper connector position. Tighten the wire retaining screws fully.11- Rotate the connection cover plate closed, making sure not to stress the connec-tions or pinch the wires. Tighten the cover plate’s retaining screw.12- Adjust the wiring at the entry point, if necessary, and properly secure fitting. This prevents wire stress and strain from pulling the connections/connectors loose.13-tab to an appropriate support point.

El modelo AD-C81Tw también incluye un filtro de paso bajo de 120Hz que puede ponerse en derivación.Qué se incluyeLa caja de su altavoz de cielo raso contiene: - el gabinete del altavoz- el conjunto de la rejilla protectora- dos soportes para instalaciones en cielo raso suspendido- soporte de anillo en C para cielo raso suspendido y otras aplicaciones de refuerzodel cielo raso.- tornillos autorroscantes (M4.2 X 1.4 X 10mm) para fijar el anillo en C a los soportes- sujetador de la rejilla usado para sujetar entre sí las líneas de retención de plásticode la rejilla- conjunto de conectadores tipo Phoenix para conectar la señal y hacer conexiones decadena en margarita- escudo de pintura- tela para la rejillaOpciones de instalaciónLos altavoces AcousticDesign de montaje en cielo raso se pueden montar en cielos raso suspendidos, así como en los tipos no suspendidos. Recomendamos que consulte a un instalador profesional para garantizar la seguridad, una instalación de calidad y un rendimiento acústico óptimo.Para aplicaciones en cielo raso suspendido, se deben usar los soportes para cielo raso suspendido con el soporte de anillo en C. Los soportes para cielo raso suspendido están diseñados para ajustarse en barras en T con una separación de enrejado de 24 pulgadas o 600 mm. Los soportes no se conectan en la barra en T; la curva “V” angular se asienta sobre la barra en T y atrapará a la barra en T en caso de una falla o caída del recubrimiento.Para otros tipos de cielo raso, se puede usar el soporte de anillo en C para reforzar la superficie de montaje. Si el cielo raso es adecuadamente resistente, el altavoz se puede asegurar en la abertura sin necesidad de refuerzo adicional.Las conexiones de audio se hacen directamente al bloque de terminales cerámicos o usando conectores para bloques de terminales. Se proporcionan dos juegos de terminales: un juego para la conexión de la señal y el otro para la conexión traspasante (o de cadena en margarita) a los otros altavoces del mismo circuito de distribución.Se proporcionan dos características de seguridad, una lengüeta de seguridad para sujetar la caja y una cadena de seguridad para retener la rejilla. La lengüeta de la caja es una lengüeta metálica que se encuentra en la parte superior de la caja o cerca de ella y que es adecuada para fijar el altavoz en la estructura del edificio; esto proporciona una máxima seguridad en caso de que la estructura del cielo raso fallara por alguna razón. La cadena de seguridad de la rejilla evita que la rejilla se caiga en el caso de que se aflojara por la vibración.Otras recomendaciones e información importante•Para retirar la rejilla: La rejilla se puede quitar levantando cuidadosamente alrededor de su borde externo o insertando un perno o gancho metálico pequeño en las aberturas de la rejilla y halando uniformemente alrededor de su perímetro.•Si durante la operación se escucha un cascabeleo o un zumbido, es posible que sea necesario instalar material deamortiguamiento de la vibración entre los rieles de apoyo y el recubrimiento del cielo raso y/o las barras en T.•Los rieles de apoyo tienen orificios a lo largo de su longitud útil para conectar el soporte de anillo en C. Esto permite que la abertura se coloque en muchas posiciones a lo largo del ancho del recubrimiento del cielo raso.1-de corte en la superficie del cielo raso.2-o agrietar la superficie de montaje.3- Hale los cables a través del orificio.4- Pase los dos soportes del cielo raso suspendido a través del orificio y colóquelos a hacer en un cielo raso no suspendido, no es necesario usar estas abrazaderas.5-abertura en el orificio, y luego gire el soporte para que pase a través del orificio. Asegúrese de que los cables pasen a través del anillo.6- Coloque los soportes y asegure el soporte de anillo en C en cada uno de los soportes usando los tornillos que se proporcionan. Si la instalación se va a hacer en un cielo raso no suspendido, no haga este paso.7- Afloje el tornillo de retención de la placa de la cubierta de conexión y abra la cubierta. Instale un accesorio en el orificio provisto en la placa de la cubierta.8- Apoye temporalmente la caja para poder pasar los cables a través de la parte superior de la caja con suficiente holgura para preparar y terminar los cables.9- Ubique los conectores del bloque de terminales que se incluyen con el altavoz. Afloje totalmente los tornillos de retención del cable.10-tornillos de retención del cable.11-placa de la cubierta.12- Ajuste el cableado en el punto de entrada,seguro. Esto evita tensión y estrés al halar las conexiones o los conectores para aflojarlos.13- Conecte un cable de seguridad (un cable de soporte secundario) de la lengüeta de conexión de la caja a un punto de apoyo apropiado. Este cable y los puntos de conexión deben ser lo suficientemente fuertes como para soportar varias veces el peso del altavoz en caso de una falla del sistema primario de montaje.14- Introduzca la caja en la abertura del cielo raso, asegurándose de que todos los abrazaderas de montaje del altavoz.15- Coloque el conmutador selector de tomas en la posición deseada. En los sistemas de 70 V, se pueden usar las cuatro posiciones. No use el ajuste mayor de tomas con sistemas de 100 V.

PJB Piranha 扬声器说明书
6T - 8T- 9B - 16B - 24B LOUDSPEAKER ENCLOSURESOWNER’S MANUALThank you for purchasing PJB Piranha Speakers. A great deal of dedication and passion went into designing and building this no-compromise, high performance loudspeaker system. These are dedicated loudspeakers for the “demanding” bassist. Reading this manual will enable you to get the best performance from them and it will give you many years of service.READ THIS FIRST• Before using the Piranha Speakers please read ALL the instructions.• On receipt of product, check for any signs of physical damage arising from shipping. If any damage is visible contact your dealer.• Keep all original packing.• Never use this product in the vicinity of water.• Never connect more than one amplifier to a speaker!• The acoustic output of this loudspeaker can generate enough sound pressure levels to cause PERMANENT hearing damage to you and anyone else who is close to it. Take caution with how much volume is used. If you suffer from ears ringing, this is an indication that you may be damaging your hearing.• Do not locate this speaker near any heat source.• This speaker must be connected to an amplifier as specified in this manual.• Do not let any liquid or foreign objects fall into any openings of the speaker.• Do not use this speaker if it has:1. Suffered by considerable physical damage.2. Been subjected to any liquids, rain or moisture.3. Damaged cables connected to it.INTRODUCTIONPJB loudspeakers are a radically different approach to dedicated bass instrument speakers not only in design philosophy but also in performance and build quality. Fully understanding our speakers will enable you to get the best out of your playing ability and sound. On the surface the PJB cabinet may look somewhat of a gimmick to some. However, behind this unique appearance is a very solid scientific foundation.At the heart of your speaker cabinet is a specifically designed bass instrument transducer, a tiny 5” driver in comparison to what is considered normal size bass reproducer. There has been a mis-perception that bigger drivers are better for bass loudspeakers. The performance of PJB speakers can prove to you small drivers can be just as powerful and more agile in response than big drivers. For more information of our technology, we strongly suggest you to visit the “tech info” section of our website. Many music instrument amplifier manufacturers simply stuff boxes with marketable driver configurations with little or no regard to the science of electro-acoustics. As a result bass, players have had to compensate for the inadequacies of these speaker systems with effects, EQ, limiters and even their playing techniques. Now for the first time, bass players can be liberated with the totally radical new concept amplification from PJB.PJB speakers will only perform at their best if they are used with other PJB speakers. We recommend that you do not use them with any other brand name speakers. If you do, your overall sound quality will be greatly impaired, as the other speakers will not be working as precisely in the same time or frequency domain as PJB speakers. A comparable example is that you would not want to have a mixture of different tires on your car, since road holding would be impaired. PJB speakers have been calculated using the latest computer aided design software to enable them to work at the absolute optimum electro-acoustic performance in various combinations. Like your instrument, you will only get the best from your speakers if they are set up correctly.Setting up your speakersIdeally you should be connecting up your speakers to PJB amplifiers because these are designed to match perfectly together.Before turning on any power, connect up your speakers to the amplifier. Keep the speaker cables as short as possible. We recommend the PJB speaker cables. Only Speakon connectors are used on all our cabinets and amplifiers because they are simply better suited for high current applications than ¼ inch jacks.The 9B, 16B and 24B enclosures can be used singularly but there will be a great sonic improvement if you combine these cabinets with the 6T or 8T. The 6T is designed for use with 9B .The 8T will work with 16B or 24B. This is because these configurations allow exactly the same power across each speaker. Using a 6T on top of a 16B will work but the drivers in the 6T will individually receive more power than the drivers in the 16B, consequently limiting headroom of the system. Please refer to the diagram of “Possible Speaker Configuration” on page 8 for alternative configurations. CAUTION!Take great care in stacking speakers. Make sure locked wheels and rubber feet are sitting correctly in the cabinet recesses. Taller configuration stacks will have higher centers of gravity and therefore less stability. DO NOT try to move speakers and amps stacked on each other. A large loudspeaker enclosure falling could cause you or others serious injury. Take the greatest of care when transporting your rig. Speakers should be rolled on casters individually and not stacked when doing so. Do not take any unnecessary short cuts that you may regret!ALWAYS LOCK FRONTWHEELS LIKE THIS ON THEGROUND SPEAKER. THISWILL GREATLY IMPROVESTABILITY WHEN STACKINGCABINETS.Matching Speakers to amplifiers.Many amplifier companies specify using 4 or 8Ω speakers. In reality, there is not such thing as a speaker with these constant impedance ratings. Typically 4 or 8Ω ratings are what are referred to as the minimum impedance and that will determine what is a safe load for your amplifier. It is easily possible for an 8Ω speaker to vary from 8 to 40Ω or more. Some speakers that are rated at 8Ω may have a lower actual rating than 8Ω. PJB speakers are rated at their minimum impedance point. That makes them an easy load for just about any amplifier. Just about any amplifier that can run down to 4Ω or even 2Ω can handle any impedance from a high 32Ω down to 4 or 2Ω any anything in between. So if you have a 5.3Ω load, it will not bother your amp at all. It may be even perform better on this than a 4Ω load. It depends on your amp. PJB amps will handle any of the speaker combinations laid out in this manual with ease.CablesHigh quality bass amplification demands low-loss, high current speaker cables. Using cables that is not specifically designed for this application will result in significant degradation of your speaker’s performance. PJB cables are ultra-low resistance with high current capability, improving your speaker’s definition and control.We recommend for best results that you use PJB speaker cables since they are matched to the performance of these speakersPJB SPEAKER CABLESImpedance & Phase Response of PJB Speaker Cables versus Leading Brand’s EquivalentConnecting up your speakersAll PJB speakers feature genuine Neutrik NL4MP SPEAKON, airtight loudspeaker sockets featuring low resistance silver contacts. These have a current rating of 40 amps making them the ideal bass instrument speaker connection. Using both the 2 positive and 2 negative connections in parallel results in each PJB speaker connection capable of handling peaks of up to 80 amps!The two Speakons on the rear recess plate allow parallel-connected speakers to your amplifier. Just plug your amplifier into the input socket and then connect your other speaker to the link out socket. If you are using two speakers connected to your amplifier a better way of connection is to use each speaker directly connected to your amp’s output-sockets. This will give a lower cable resistance (due to the speaker cables also running in parallel) improving your sound.How to calculate the total impedance of multiple Piranha speakersCount number of speakers across and multiply by 8 (example 4 across = 32)Divide this number (example 32) by number of rows down. (Example 8) = 4 Ohm Load.DO NOT CONNECT CABINETS TOGETHER THAT HAVE A DIFFERENT NUMBER OF DRIVERS ACROSS. (EXAMPLE: A 6T ON TOP OF A 16B This will put more power through the top cabinet, making it work harder and will limit your total power handling.)A Note on Amplifier Power and Speaker Power HandlingVery often loudspeakers and amplifier power ratings are totally misunderstood by the non-technical user for good reason. This is a complex and involving topic that will only be touched upon lightly in this manual.First the ear is not capable of telling how much power is going to a loudspeaker. Secondly ALL loudspeakers have different power ratings at each and every frequency. The amplifier will produce different power levels if the frequency changes, even if the volume is the same. Finally, we hear sound based on a logarithmic scale. So in order to perceive a note twice as loud, in theory we need 10 times the power to produce the perceived doubling of volume. In reality another parameter comes into this already complex equation. It’s called “Power Compression” which is the losses in the loudspeaker units due to heating up and reducing efficiency of converting the amplifier’s electrical power to acoustic energy.Loudspeakers are complex devices and very inefficient converters of electrical energy especially when it comes to reproducing bass frequencies. More than 90% of amp power goes to heating up the speakers and that is why the “Power Compression” factor is a major one. It is physically impossible to create a loudspeaker that is 100% efficient or even close. For bass instruments even 20% efficiency is almost impossible unless you are a billionaire!Two limiting factors determine the power handling of a bass speaker. One is the ability to withstand the heat buildup before the unit goes up on smoke. The other is the excursion capability of the cone. The cone will move in and out further not only with volume increase but also as you play lower notes. An open B or E string will cause the cone to move more than an open G-string at the same volume level. Also boosting the bass EQ on your amplifier’s tone controls will cause greater excursion on the speaker cones.PJB bass instrument speakers were developed with a focus to overcome the problem of power compression, and this is one of the reasons they outperform competitive products both in sound quality and power handling.Warranty InformationPJB speakers have a warranty period of 2 years, starting from the date of purchase. The buyer must complete and return the enclosed warranty card within 14 days of purchase.This warranty covers defect in materials or workmanship that occurs in normal use.

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 4.32.

Attach the metal grille and logo,if desired.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 SPEAKERFRAME AND GRILLEStudio L in-wall and in-ceiling loudspeakers can be painted to match anydécor. 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 painting. 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 setup options 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.TWEETER-LEVEL CONTROLIn most typical listening rooms, this switch should be left in the neutral or “0” position. This setting will deliver the most neutral and balanced sound.In some extreme cases, it may be desirable to slightly boost or cut the tweeter’s output, depending upon the room layout, construction and furnishings.If the room is sparsely furnished, contains large exposed windows or is otherwise very reverberant, you may want to set the control to the “–”(–1.5dB) position. If the room is exceptionally absorbent because it is well furnished or has thick curtains and/or carpet, you may want to increasethe tweeter output by setting this switch to the “+” position (+1.5dB).BOUNDARY COMPENSATION CONTROL LS326W,LS326C,LS328CThis control is designed to be engaged when positioning the loudspeaker within two feet of another surface to eliminate the bass peak caused bythe second surface and to maintain a smooth, natural bass response. For example, if you need to install an in-ceiling speaker within two feet of a side wall or corner, it is recommended that the Boundary Compensation control be set to the “On” position. Likewise, if it is necessary to install an in-wall speaker within two feet of the floor, ceiling or corner, the control should be set to the “On” position. In all other installations, the control should typically be set to “Off”.6SPECIFICATIONSStudio L L226W L226C L228CFrequency Range (–6dB)30Hz – 20kHz30Hz – 20kHz28Hz – 20kHzRecommended10 – 125 Watts10 – 125 Watts10 – 135 WattsAmplifier Power RangeSensitivity89dB89dB90dB(2.83V @1 meter)Nominal Impedance8 Ohms8 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 @1 meter)Nominal Impedance8 Ohms8 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)7owner’s manual are in compliance with technical standards:Laurent Rault。
