The AD-S28Tw model offers excellent acoustic perfor-mance in an easy-to-install and attractive enclosure. Please review these instructions and carefully follow the recommenda-tions. Consult a licensed installation professional if you are uncertain about any mounting issues.The AD-S28Tw features dual 8” (200 mm) low frequency (LF) drivers in a ported bandpass enclosure. The AD-S28Tw is equipped with an audio transformer suitable for 70V and 100V distributed systems, as well as a tap-selector switch which can bypass the transformer for 8 ohm applications. The AD-S28Tw also includes a bypassable 120Hz low pass filter. The marine-grade plywood enclosure may be used in floor-standing as well as yoke mounted and suspended applications.What’s IncludedYour surface mount subwoofer includes:- the loudspeaker cabinet with grille - extra grille backing foam sheet - steel yoke bracket- steel suspension point shear plates (x3)- steel M6 forged shoulder eyebolts (x4)- hex head / phillips-head M6 bolts (x3)- flat washers (x4)- rubber yoke mounting gaskets (x2)- rubber feet with integrated attachment bolts (x4)Features1 - Marine grade plywood enclosure, painted2 - ABS grille endcaps3 - Steel grille with foam backing4 - Rotatable QSC logo badge5 - Integrated M6 suspension points6 - Input cup with rotating door (see detail)7 - Rubber feet (shown attached)8 - Service access panel9 - Low Pass Filter Switch 10 - Transformer tap switch11 - Input cup door (shown in open position)12 - Input screw terminals1234567811Attaching the FeetLocate the four M6 attachment points on the bottom of the sub. Consult the following illustrations and pay careful attention to which attachment points are correct.Installation OptionsThe AD-S28Tw has been designed for installation flexibility. The subwoofer may be mounted using a number of different suspension techniques, as well as being easily shelf or floor mounted. The QSC logo on the grille is rotatable to accommo-date horizontal or vertical orientation. While low frequency products do not have directional dispersion characteristics, all of the sonic energy produced by this subwoofer exits the cabinet through the port due to the ported bandpass design. For that reason, the port (located behind the grille) mUSt NOt be physically blocked by anything, and should not be placed within twelve (12) inches of any objects larger than 3 to 4 inches (75 to 100 mm).When the subwoofer is floor or shelf standing it is recommended that the rubber feet be attached.For suspended installations, the enclosure can be attached with flypoints or the included yoke bracket. The enclosure can be oriented in multiple positions when suspended:Remove the screws from the selected attachment points using a #2 phillips-head screw driver or electric driver. Remove only the four screws for the attachment of the feet. DO NOt REmOVE ANY OtHER SCREWS. If a screw hole is left open, it will create an airleak which will cause noise and compromise the performance of the cabinet.Screw the rubber feet into the attachment point. It should not require significant force to rotate the foot if the threads are properly engaged. If the foot is not screwing in easily, remove it and engage it in the threads again.Do not use any tools for installation of the feet. the rubber may be damaged if a tool is used.Continue rotating the foot until it makes contact with the cabinet. Only hand generated force is necessary to properly seal the hole and keep the foot screwed in.Once the feet are attached, place the subwoofer in the desired location.mounting the Subwoofer Using the YokeThe yoke can be used to mount the subwoofer either on a vertical surface, like a wall, or from an overhead surface, like a ceiling or ceiling beams. In either case, the attachment points on the enclosure for securing the yoke are the same. The yoke is designed to attach to only two sides of the cabinet and cannot be attached to any other surfaces. The yoke features slots to allow for either maximum rotation of the cabinet, or for minimum separation between the cabinet and the mounting surface. Consult the following illustrations.Once the subwoofer is secured in position, the QSC logo can be rotated if desired. If the logo is difficult to rotate the first time, a tool may be required. A small flat-head screw driver is recommended. Gently work the tool between the logo badge and the grille to allow rotation. Exercise care to avoid scratching the grille surface.the yoke must be secured to structure that is capable of supporting the weight of the subwoofer and must be connected using load rated hardware.Consult a licensed, professional engineer when any doubt or questions arise regarding a physicalequipment installation.1 - Remove the screws from the selected attachment points using a #2 phillips-head screw driver or electric driver. Remove only the two screws that will be used for the attachment of the yoke. DO NOt REmOVE ANY OtHER SCREWS. If a screw hole is left open, it will create an airleak which will cause noise and compromise the performance of the cabinet.2 - Remove the adhesive backing from the rubber pad and attach the pad to the cabinet by pressing the adhesive coated side against the cabinet. Make sure not to obstruct the attachment holes. The adhesive will hold the pad in place as you mount the enclosure to the yoke.3 - Align the yoke with the attachment points on the subwoofer and place the attachment hardware according to the il-lustration.4 - Tighten the hex-head/phillips-head bolts enough to hold the subwoofer in place but loose enough to rotate with minimum force. Check the alignment of the subwoofer for best desired appearance. As long as the port is not blocked, the alignment of the subwoofer will not affect performance. Once positioned, tighten the bolts so that the subwoofer will not rotate with force.Hex-head / phillips-head m6 BoltLock washer Flat washerAdhesive rubber pad (affixed to enclosure)It is recommended that the yoke be attached to the mounting surface prior to attaching the yoke to the subwoofer enclo-sure. The yoke is designed to allow attachment to the mounting surface with mounting points ranging from 5.5 in (140 mm) to 6.5 in (165 mm) apart.Suspending the Subwoofer Using Eyebolts and Shear PlatesThe subwoofer can be suspended using the included eyebolts. There are three possible orientations for installing the sub-woofer this way.1. Port facing laterally, subwoofer in “wide” orientation2. Port facing laterally, subwoofer in “narrow” orientation3. Port facing downFor each of these orientations, the points for eyebolt and shear plate attachment are very specific. Please consult the follow-ing illustrations to understand each orientation and pay careful attention to which attachment points are correct.Any unused attachment point can be used as a safety/seismic secondary attachment. Attach an eyebolt to an available at-tachment point according to the section of the manual titled: Suspending the Subwoofer Using Eyebolts and Shear Plates. Be sure to leave less than 12 in (300 mm) of slack in the secondary attachment cable.the safety/seismic secondary attachment must be secured to structure that is capable of supportingthe weight of the subwoofer and must be connected using load rated hardware.Shear PlatesAlign the mounting hole of the shear plate with the enclosure attachment point with the rubber pad between the plate and the cabinet. Place the attachment hardware according to the illustration. Tighten the hex-head bolts enough to hold the shear plate in place but leave it just loose enough to rotate with minimum force. Check the alignment of the shear plate so that it is perpendicular to the cabinet. Once positioned, tighten the bolts so that the shear will not rotate with force. the shear plates must be secured to structure that is capable of supporting the weight of the subwoofer and must be connected using load rated hardware.Consult a licensed, professional engineer when any doubt or questions arise regarding a physicalequipment installation.Remove the screws from the selected attachment points using a #2 phillips-head screw driver or electric driver. Remove only the screws that will be used for the attachment eyebolts or shear plates. DO NOt REmOVE ANY OtHER SCREWS. If a screw hole is left open, it will create an airleak which will cause noise and compromise the performance of the cabinet.The locations of the eyebolts were designed to suspend the subwoofer using the fewest number of attachment points. Where possible there are only three attachment points to be used. These points are located so that the triangle they form “encloses” the center of gravity and the subwoofer will balance with all three points suspended. In some cases, one or more of the attachment points is not on a cabinet side that is facing up. In these cases DO NOt USE AN EYEBOLt . In this position, the eyebolt will be in shear and the eyebolt is greatly derated in this use. For these attachment points a SHEAR PLAtE mUSt BE USED FOR SUSPENDING the subwoofer.EyeboltsScrew the eyebolt into the attachment point. It should not require significant force to rotate the eyebolt if the threads are properly engaged. If the eyebolt is not screwing in easily, remove it and engage it in the threads again.Continue rotating the eyebolt until it makes contact with the cabinet. Once the eyebolt shoulder has made contact with the cabinet, continue to rotate it until it reaches the desired alignment with the cabinet. If necessary, use a tool such as a long handheld screwdriver to tighten it. Place the blade of the screwdriver through the eyebolt and use it to rotate the eyebolt. It is not necessary to tighten the eyebolt to the point that it cannot rotate any further. Once the shoulder has made contact with the enclosure, any further tightening is actually cutting the shoulder of the eyebolt in to the wood of the cabinet. This “cutting in” coupled with the tension of suspension on the eyebolt will prevent the eyebolt from loosening once the cabinet is suspended. the eyebolts must be secured to structure that is capable of supporting the weight of the subwoofer and must be connected using load rated hardware.Consult a licensed, professional engineer when any doubt or questions arise regarding a physicalequipment installation.Hex-head / phillips-head m6 Bolt Lock washer Flat washer Shear plate Attached rubber padWiring Signal to the SubwooferThe input terminal is on the rear of the subwoofer and is covered by a hinged door. Open the door to expose the screw terminals. There are four sets of screw terminals arranged in positive/negative pairs for parallel wiring. One pair is labeled for input (receive signal) and the other pair is labeled for output (pass signal to next device). But be sure that the wiring is consistent and paired properly.The terminals are designed to accept wiring between 18 AWG (1.02 mm) and 12 AWG (2.053). Use a #2 Phillips-h ead screw driver to loosen the terminal screw. Strip the insulation for the signal wire so that approximately 3/4 in (20 mm) of bare wire is exposed. Place the bare wire under the screw down plate and retighten the screw as tightly as possible with a manual screw driver.The input and output pairs are parallel. The output terminals will pass exactly what is presented at the input terminals. If low impedance full range audio signal is presented at the input (it is recommended that the subwoofer’s internal low pass filter be used in this instance) then low impedance full range audio will be passed to the next device wired to the parallel output of the AD-S28Tw. If high impedance 70V or 100V signal is presented at the input, then high impedance 70V or 100V signal will be passed to the next device wired to the parallel output of the AD-S28Tw. If an external low pass filter is used and only low passed signal is presented at the input, then only low passed audio will go to the next device wired to the parallel output of the device.Using 70V or 100V Drive for Distributed Audio SystemsHigh impedance 70V or 100V drive allows for a typically larger number of loudspeakers to be wired to one amplifier output and allows smaller wire gauge to be used over longer runs with less loss. When using high impedance drive, the internal transformer on the AD-S28Tw mUSt be engaged. To do this, rotate the tap selector switch so that it is aligned with one of the four (three for 100V) transformer tap settings. The tap setting on the switch selects which tap of the transformer is used to buffer the signal and is expressed in terms of the power draw on the amplifier. The larger the tap, the more output from the subwoofer. Transformer tap settings should be considered when selecting an amplifier to drive the system. A good “rule of thumb” is that the rated power of the amplifier per channel should be the minimum of all of the connected taps added together with an additional 20% for headroom. An example: 8 Loudspeakers each tapped at 50W 50 + 50 + 50 +50 + 50 + 50 + 50 + 50 = 400 or8 x 50 = 400400 + 20% = 480Use an amplifier with a minimum channel power rating of 480WMultitap 70V / 100V transformers can saturate with low frequency energy. Saturation causes analog clipping distortion of the signal. The transformer use in the AD-S28Tw is custom designed to saturate at frequencies below the functional low frequency range of the AD-S28Tw. It is recommended that a -6 dB, 30 Hz high pass filter be engaged to prevent saturation of the transformer.Any unused attachment point can be used as a safety/seismic secondary attachment. Attach an eyebolt to an available attachment point according to the Eyebolt instructions above. Be sure to leave less than 12 in (300 mm) of slack in the secondary attachment cable. the safety/seismic secondary attachment must be secured to structure that is capable of supportingthe weight of the subwoofer and must be connected using load rated hardware.Once the subwoofer is secured in position, the QSC logo can be rotated if desired. If the logo is difficult to rotate the first time, a tool may be required. A small flat-head screw driver is recommended. Gently work the tool between the logo badge and the grille to allow rotation. Exercise care to avoid scratching the grille surface.SpecificationsAD-S28twFrequency Response 1: 42 - 165 Hz (-3 dB), 36 - 205 Hz (-10 dB)maximum Output 2: 118 dB SPL continuous rms output (Calculated) 124 dB SPL peak outputtransducers:Dual 8 inch (200 mm) weather resistant, polypropylene cone woofer, rubber surround Impedance (ohm):8.0 n om. / 9.5 min at 77 Hz with LPF “IN” / 5.3 min at 63 Hz with LPF “OUT”Power Handling 3: RMS (IEC 2hrs): 250 W Recommended amp rating: 500 W Sensitivity: 94 dB, 2.83 V, 1 m, ground plane (2P )Internal Filter:120 Hz low pass, passive, bypassableOptional Processing: 120 Hz low pass >12 dB/octave, internal filter bypassedtransformer: Type:Custom low distortion laminated core, wide bandwidth designTaps: 70 V: 200, 100, 50, 25 W / 100 V: 200, 100, 50 W / 8 W selected by rotary switch Connectors: Four position screw terminals; 2 in / 2 out Controls: Transformer tap selector and bypass; rotary switchLow pass filter rotary switchEnclosure Configuration: Dual chamber bandpass, one chamber ported, surface mount Enclosure Construction: Marine grade plywoodEnvironmental:IEC 60529 IP-x4 rated against dust and water incursion.

德国AD专业音响声利谱音响AD的发展史AD 的前身由荷兰人Luis van Rossum 和Frans van Meulebroeck ，在1974 年创立。

这是个完美的组合，前者是个具有国际视野的企业家，而后者是个来自皇家荷兰飞利浦的资深电子工程师。

当时，公司的基地位于西班牙的东南海岸的Altea.起初公司的名字叫Prosound，在70年代是个旅游业非常兴旺的年代，Prosound公司就是为这些日益扩张的酒吧，迪斯科，音乐会，节日等体统扩声系统。

Prosound公司为它们提供了出色的专业服务，通过客户的口耳相传，很快就建立了良好的口碑，因为Prosound提供的是一整套的服务：功放，音箱系统已经处理器。

这在那个年代无疑是少见的Prosound的成功一直延续到80年代。

期间推出的PS系列成为公司发展的一个里程碑。

它们的可靠性和耐用性确保其在假日庆典，酒吧，摇滚音乐会中日复一日的苛刻使用，从而蜚声整个西班牙，Prosound的口碑从此被广泛认可，因为它的客户知道，Prosound的产品在实际的应用中从来没有令人失望过，无论是专业人士苛刻使用，还是迷恋疯狂夜生活的西班牙的年轻一代的粗暴使用。

而事实上，时至今天很多PS系列的音响在正常使用的25年后依然表现出色，屹立不倒。

随着产品逐步扩张到国际市场，Prosound决定把名字改成Audience Delight Systems（简称AD），是为了避免在西欧的语系中造成混淆。

AD成为数字音频处理领域的先锋之一。

它的数字音频处理器AD-1000 DC在获得1994年的荷兰科技创新大奖就证明了这一切。

AD一直贯彻行事低调的作风，埋头搞科技创新，它相信唯有这样才能真正保持在业界领先的位置和良好的口碑，而并非过分地打广告，做推广，做促销。

在90年代初德国著名的音响工程师Juergen Eicker加入了AD。

他被AD的理念所深深吸引，从此Juergen Eicker全面负责AD的研发工作。

电子分频器的使用技巧在一套音响系统中提到分频器一般来说是指能将：20Hz--20000Hz频段的音频信号分成合适的、不同的几个频率段，然后分别送给相应功放，用来推动相应音箱的一种音响周边设备。

下面简单介绍一下分频器在音响系统中的应用。

一、我们为什么要使用电子分频器大家知道，声音的频率范围是在20Hz—20000Hz之间，现在大多数前级音频处理设备的频率范围是可以达到这样宽度的，但目前的扬声器却成了一个瓶颈部分，我们奢想使用一种或简单几只扬声器就能放送出接近20Hz--20000Hz这样宽频率的声音是很难做到的，因为现在单只喇叭的有效工作频率范围都不是很宽。

鉴于此电声工程师们就设计出了在不同频率段内工作的音箱，如：1、重低音音箱：让它在大约30-200Hz的频率范围内工作。

2、低中音音箱：让它在大约200-2000Hz的频率范围内工作。

3、高音音箱：让它在大约2000-20000Hz的频率范围内工作。

如此以来我们就可以利用在不同频率段工作的不同种类的音箱配置一套能最大限度接近声音真实频率（20Hz--20000Hz）的音响系统了。

当然不同音箱设备的构成和参数是不同的，我上面说的是以一个三分频的系统为例，实际使用上还有其它诸如：2分频或4分频等系统，而且不同音响系统中由于采用的音箱会有区别，因此这些音箱的工作频率也不可能是固定相同的，但大体的原理和思路是一样的。

那么有一个问题就是：我们如何给这些在不同频率段工作的、不同种类的音箱灵活分配音频频率呢？为了解决这个问题，电子分频器就应运而生了，它可以根据不同音箱工作频率的需要提供合适的频率段，例如：1、我们可以用电子分频器将高频信号通过功放送到高音扬声器中。

2、可以用电子分频器将中频信号通过功放送到中音扬声器中。

3、可以用电子分频器将低频信号通过功放送到低音扬声器中。

这样高、中、低频信号独立输出、互不干涉，因此可以尽可能发挥不同扬声器的工作频段优势，使音响系统中各频段声音重放显得更加均衡一些，使声音更具层次感，使音色更加完美。
