JBL EON600 15寸两路多功能自供电音响说明书
15” TWO-WAY MULTIPURPOSESELF-POWERED SOUND REINFORCEMENTA TRUE STEP FORWARD IN TECHNOLOGYMore than just another great JBL sound system, the new EON600 is a true step forward in technology developed specifi cally to deliver the best sound possible regardless of its application. Completely rethinking how truly good an affordable self-contained, portable PA system can be, JBL engineers purposely designed and built the EON600 from the ground up featuring JBL ’s advanced waveguide technology, JBL designed and manufactured transducers, and convenient, wireless remote control of its onboard DSP EQ parameters via Bluetooth. This total redesign of the EON platform leverages the latest technologies in cabinet materials, acoustic science, transducer design and user friendliness that delivers the extraordinary quality of a high-end studio monitor in a fully professional, highly fl exible, easy to use, portable system for today’s working musicians and sound providers.39 L B/ 17.69 K GFOR EASY PORTABILITY1000WATTHIGH-PERFORMANCEPOWERED SPEAKER SYSTEMPURPOSEFUL PRODUCT DESIGNmake the 600 easy to carry and move around. Integrated hardware mounts, designed into the enclosures, allow each model to be flownwhen required. And indexed feet molded into the enclosures allow for convenient storage and transport, secure stacking for stage monitor andtraditional stand up configurations, and unique acoustic configurations.JBL WAVEGUIDE TECHNOLOGYapproach to waveguide design. JBL engineers examined the radiation characteristics of the EON’s high and low frequency drivers at 36different points employing JBL’s exclusive, state of the art measurement techniques, then designed individual waveguides for both components that control the sound radiation at the high frequencies, the crossover point and at the low frequencies. Special fl uting is designed into the structure that guides the frequencies through the full range of the system. The result is consistent response throughout its 90 degree coverage pattern. The quality and consistency between on axis and off axis response delivers uniform coverage and high intelligibility throughout the coverage area, which means the EON600’s smooth, transparent sound is the same for the entire audience.BLUETOOTH INTEGRATIONKnowing that fiadjusting the 5-way, user defi nable parametric EQ, and saving and recalling user presets.TYPICAL COVERAGEEON600 COVERAGEEON600TYPICALAMPLIFICATIONThe EON600 features built-in 1000 watt power amplifi cation designed, as with all EON components to perfectly complement theperformance of the drivers, delivering exceptional headroom with power to spare whether a fi xed pa application or the demands of a gigging band.

Product Description Product Feature Identification Installation Preparations Step-By-Step Installation and Wiring Painting the Speaker Maintenance Contacting JBL Table of Contents2346111214Product DescriptionThe JBL Control Contractor ceiling loudspeakers utilize innovative design and materialsto provide premium level performance from compact in-ceiling speakers.CONTROL 24C MICRO- Most compact of the JBL ceiling speakers,the Control 24C Micro contains a 4" woofer and a ¾" titanium-coated tweeter,providing high-fidelitysound over an extremely wide coverage area.The Control 24C Micro also has a smallbackcan and is ideal for smaller ceiling spaces.CONTROL 24CT MICRO- The Control 24CT Micro includes a multitap transformer for use on 70V or 100V line distribution systems.The transformer has a top tap rating of9 Watts.CONTROL 24CT MICROPLUS- The Control 24CT MicroPlus includes a multitaptransformer for use on 70V or 100V line distribution systems.The transformer has a top tap rating of25 Watts.2Product Feature Identification (Control 24CT Micro Shown)Attachment Screw TweeterWoofer Steel Backcan Connector Block RotatingMountingTabStrain Relief TieSeismic Tab(SecondarySupport)3Attachment pointsfor included orinstaller-providedstrain-relief fittings.Tuning PortInstallation PreparationsThe entire installation can be accomplished,if necessary,without requiring access abovethe ceiling.Bracketry for use with either suspended ceilings or sheetrock ceilings isincluded.The speaker is held securely in place via mounting ears which lock into place. OPTIONAL PRE-INSTALLATION BRACKETS42.The optional PLASTER-RING BRACKET (or "mud ring") is identical to the New Construction Bracket,with the addition of a circular offset,forming an edge guide for sheet rock plastering.The bracket has wings that attach to the building structure.Sheet rock is typically either precut or cut with a rotary cutting tool.The sheet rock hole is then plastered (or "mudded") up to the ring to create a seamless cutout.5Step-by-Step Installation and WiringThe installation system has been designed so that the entire installation can be accom-plished from beneath the ceiling,for instances when access above the tile is not possibleor practical.However,in some cases it may be easier with removable ceiling tiles toaccess from both the top and bottom of the ceiling tile during various phases of theinstallation.Step 2 - Insert Backing Hardware Through the Hole.Packaged with the speakers are two types of backing hardware - a C-shaped backing-plate bracket and two tile rails.Suspended Ceilings- Insert the C-plate through the hole cut in the ceiling tile.Placethe C-plate around the hole with the tabs located as shown on Figure 4.Insert the tilerails through the cut hole in the ceiling tile.Snap the two rails into the two tabs in theC-plate and align the rails so that the ends extend OVER the T-channel grid on theupper side of the tile.Secure the rails onto the C-bracket tabs by inserting a screwthough each tab into the rail.This can all be accomplished from below the ceiling tile,if necessary.67Figure 4:C-Bracket and Tile Rail Positioning on Ceiling TileTile Rails:The tile rails are designed to fit either standard 24-inch wide tiles or 600-mm wide tiles.The tile rail pieces do NOT physically attach to the T-grid struts.Instead,the inverted-V shape at the ends of the rails sit OVER the T-grid strut.During normal operation,the rails are supported by the edge of the tile.In the unlikely even that the tile comes out or falls apart,the ends of the support rails are designed to catch onto the T-grid,providing secure support to hold the loudspeaker assembly in place.Cutout Placement :The tile rails are pre-punched with attachment holes along their length.Placement is not limited to the center of the tile,as is the case with many other tile rail support systems.Non-Suspended Ceiling Types:The C-bracket can be optionally used by itself to shore up the ceiling material and to spread out the clamping force from the tab clamps.Insert the C-plate through the cut hole in the ceiling and place it on the back side of thehole before inserting the speaker.Step 3 - Connect the Wiring to the Input Terminal Block.Connect the wiring to the UL &CE-rated,touch-proof terminal block that is attached to the side of the speaker by stripping the insulation back about about 3/16 inches (5 mm) [do not strip any longer than this],inserting the bare end of wire into the connector and screwing the hold-down screw until tight using a small flat blade screwdriver.Tighten any unused screws to avoid vibration.Figure 5:Connecting Wires to Connector8Control 24CT Micro:9W 4W 2W 1W 0.5W Com 70VN.C. 9W 4W 2W 1W C om 100VControl 24CT MicroPlus:N.C.N.C.6W 12W 25W Com 70V N.C.N.C.12W 25W 100V Control 24C Micro:+-Hookup ChartHookup ChartFor Control 24CT Micro and the Control 24CT MicroPlus,connect the negative input to the "Common" terminal and connect the positive input to the appropriate tap.The input pins correspond to the taps of the transformer indicated on the label above each connec-tor.For example,if the system is being driven from a 70V Distributed Line,and the 2W tap is the desired connection,the positive input would be made to the input marked "2W ,Violet." The negative connection would be made to the "Common" pin.On the Control 24C Micro,low impedance version,connect the negative wire to the "-"terminal and connect the positive wire to the "+" terminal.All other pins are "No Connection."Paralleling Input Terminals - It is common to run two sets of wires - one set is the input to the speaker and the other is the feed to the next speaker.In this case,simply par-allel the two sets of wires to the same terminals on the speaker's terminal block.Step 4 - Add included metal strain relief as necessary.The Control 24C/CT Micro and the 24CT MicroPlus are equipped with two locations where the installer can affix strain relief con-nectors - one is on the back of backcan and one is on the side (for applications with shallow access).The location of these two attachment points is shown on the Product FeatureIdentification on Page 3.The installer can attach a wide variety of installer provided fittings to these points if the included equipment is not adequate for the particular installation.Refer to Figure 6 shows the strain relief INCLUDED with the Control 24C/CT Micro and Control 24CT MicroPlus.Figure 6:Included Metal Strain Relief1 - Cable Tie - If using loose wire,this cable tie can secure the loose ends of wire that are connected to the terminal block.The strap can be tightened by pulling on the loose end and then tightening the holding screw.2 - Adjustable Metal Strap - This adjustable steel tie fitting is provided for those applica-tions where it can be utilized to affix a set of wires.It can be useful for regions where such a fitting is allowed for terminating a flexible conduit.It can also be used for tight-ening down onto incoming wires to provide strain relief.It might be necessary to place electrical tape or heat shrink over any wire bundle,underneath the metal strap,to physi-cally protect the wire from the strap.3 - PEM Screws - Two screws,which are threaded into PEM fittings in the backcan,one on the back and one on the side,can be used to attach a wide variety of strain fit-tings.Please remove the correct screws with the PEM fitting,as shown on the Product Feature Identification Picture on Page 3,NOT the two screws that hold the backcan in place.Check building codes in your area for what kind of physical strain relief fittings are required in your region.Figure 7:Tightening the Cable Tie9Step 6 - Connect a Secondary Support Line to Seismic Tab- A tab is provided on the sideof the Control 24C/CT Micro and the Control 24CT MicroPlus for connection to an inde-pendent secondary support point.Some construction codes require using this secondary sup-port point,by connecting a support line to a separate secure support point.Consult construction codes in your region.Step 7 - Insert the Grille -Consider which direction the logo is facing and press the grille into place until the front of the grille is flush with the rim.Make sure grille is securely seated to pre-vent it from vibrating loose and falling.10Painting the SpeakerThe speaker's textured white finish complements most decors and does not need further finishing.Where the interior design requires it,these speakers are easy to paint.The rim can be painted before installation or in cases where the rim needs to be finished along with the ceiling,the speaker rim can be painted after attaching into the ceiling.Type of Pain t - The speaker's polystyrene rim accepts almost any type of latex or oil based paint.Two coats are recommended.Painting Process- For best results,it is recommended to use the following procedure:11Painting the Grille -Painting the grille requires removal of the logo and the internal grille cloth,then spray painting.If the grille is rolled or brush painted,the mesh may become clogged with paint and poor sound quality may result.Replace the internal grille cloth (or if damaged use new internal grille cloth) and JBL logo.· Clean the rim and grille with a light solvent such as mineral spirits by rubbingthe item with a lightly dampened cloth.Do not,however,use abrasives such assandpaper or steel wool.Nor should you use gasoline,kerosene,acetone,MEK,paint thinner,harsh detergents or other e of these cleaners mayresult in permanent damage to the enclosure.· Mask the baffle.· After cleaning,apply two or more two thin coats of either latex or oil-basedtex paint will adhere better if an oil-based primer is used first.Application can be made by rolling,brushing or spraying.These products are in compliance with the EMC Directive 89/336/EEC and Article 10 (1) ofthe directive.In compliance with Technical Regulations EN50081-1 and EN50082-1.For acopy of the model-specific CE Declaration of Conformity,contact JBL at the address listed atthe end of this manual.MaintenanceNo maintenance is required when installed in accordance with installation and wiring guidelines described in this manual.Control 24CT MicroTransformer Taps:70V: 9W, 4W, 2W, 1W, 0.5W100V;

家庭影院设备选择
家庭影院设备选择前言根据论坛内坛友实际需要，现在整理，搭配普通级、入门级、中级、中高级影音搭配，供广大坛友参考，所列出的器材基本是国内市面上能找得到，听得到的主流产品，如果国内市场不推广的话其它器材讨论也没意义了。
如果遗留了国内市场性价比高的产品也请大家补充一下（DIY，山寨产品不在本文建议范围内）。
所列出的器材在同价位中性能也算优越了，只是风格不同，越级去比高级别的没意义，一分价钱一分货。
需要特别强调的是，对于影音爱好者来说，组建选配器材，没有绝对正确的搭配组合，往往是预算、对声音的追求、器材外观、功放技术等级以及配置等等方面的权衡和妥协的结果，甚至也有对选购渠道的妥协。
本文的目的，是把目前市场上主流的器材根据市场参考价格集中供大家参考。
根据大家的需求，在考虑购买时要知道影音所用的面积，以及整体预算，一般在15平方以下，建议考虑卫星箱或书架箱（指低音在6.5寸以下的书架箱），低音炮选择在8寸或10寸。
超过15平方尽量考虑落地箱，毕竟落地箱气势比卫星同书架好很多，超过20平方低音炮至少考虑12寸以上。
有条件的话，还是多去听听，多去比较，每一个品牌风格不同，而每一个人喜欢的声音也不同，毕竟音响是以自己听感为好，别人能够给出的建议也是别人的听感，只能作为购买器材的参考。
一般上北美的产品比较适合影院系统，所出的器材也基本以电影为主，器材也表现出快速反应，干净利落，暴发力强。
欧洲产品以音乐为主，也可以很好兼容电影，其中也细分德国声，英国声，法国声，丹麦声等，其实这些声音与本国文化沉淀有关。
日本的器材以音源、功放为主，基本年年出新款，对推动影音潮流很大，日系音箱很普通，一就太低端，一就太高端（高端的产品不在论坛范围）。
国产品牌也是以HIFI为主，涉足影院的器材少之又少，惠威的声底也是向北美系靠拢，其它的基本是以低端为主，A V功放少之又少。
功放也有其特点，如天龙声底结实、够爆、影院上拳拳到肉；雅马哈音场、包围感强；马兰士音乐味重；安桥各方面均衡；索尼清晰、细腻；先锋也是清晰细腻，中高端以D类为主，在A V 功放中首创；哈曼声底厚、大电流、推力大；国产功放功率足，前级素质没日系先进，功能多。
