SW-12A三分频线性阵列音箱

SW-12A三分频线性阵列⾳箱民族情结奥运风采⼀.为什么选择R e F o w 的产品（徐总写）⼆.R e F o w （LAX）产品应⽤场所的⼯程案例（精简，并附图⽂）（由市场部从历年的⼯程案例资料上编）三. R e F o w OP-12A/SW-12A的技术介绍线性阵列是⼀种新式的扩声⽅式，它主要是利⽤波导反射原理和光学透镜的原理，应⽤到声学领域上来，主要有两种类型：障碍型和等长折射型。

障碍型阵列扬声器的⼯作原理就像玻璃镜⽚聚焦光线⼀样，类似于透镜，其障板（可为：球状、圆盘状、带状或其它不规则形状，只要其对于所涉及的频率⽽⾔尺⼨⾜够⼩）当声⾳经过它时会降低声速。

⼀个障碍型的数组透镜根据其形状的不同能够产⽣声聚焦、声扩散或平⾯波。

等长折射型阵列扬声器则采⽤⾦属板（与波长相⽐，其间隔的空间尺⼨较⼩），加强声波播送⾄更远的距离。

对于需折射声波处，⾦属板可呈“Z”形放置或简单的倾斜。

虽然看上去倾斜透镜能够改变声波折射的⽅向，但实际并⾮如此。

所增加的路径长度仅仅会改变声波的到达时间，⽽不是⽅向。

同时，线阵列是“⼀组振幅相等并同相紧密地排成⼀条直线的声辐射元素”——声学⼯程师Olson在其1957年的著作中对线阵列的描述。

⼀个理想的线声源应由⽆限多个、间距极⼩并且连续的振动元素组成，所发出的柱⾯波。

这样的线声源有⼀个不寻常的幅射特性，它的声压级衰减在每倍的距离只有3dB；⼀个点声源产⽣⼀个球⾯波，它的声压级衰减为与声源距离的平⽅反⽐关系，每倍距离衰减6个dB。

（图表⽰）传统的号筒负载扬声器，通常是按每只⾳箱的⽔平覆盖⾓度组合成⼀个扇形的阵列，从⽽试图减少导致相消⼲涉的重叠覆盖区域，在这种类型的排列中，在⼀个⽅向上想得到理想的清晰度，只能朝这个⽅向使⽤单个扬声器扩声。

但是，我们在现实的扩声⼯作中，为了达到最远的距离和更⾼的声压级，就不得不采⽤群集的⾳箱阵群来加⼤声功率，提⾼声场覆盖⾯积！⽽采取的“群集⾳箱阵群”的扩声⽅式，⼜往往导致声波辐射不能很好地耦合，⼲涉不能控制，这些⼲涉的声源所产⽣的混乱的声场，还浪费声能！影响声⾳的覆盖范围，影响到声波图形的控制，影响到分析⼒和整体的声⾳质量！要达到相同的声压级，就需要向⼀个单个的，原本清晰的声源提供更⼤的功率！（附图说明）为了⽐较形象地说明这个原理，举⼀个⽇常中我们经常会做的⼀个事例，想想我们向池塘⽔中扔⽯⼦，会发⽣什么呢。

Three-Channel Guitar Amplifier with DSP and Channel TrackingOwner’s ManualTABLE OF CONTENTSIntroduction (3)Channel Tracking (4)The Front Panel (5)The Rear Panel (6)The DSP Section (7)Using the Footswitch with the DSP (8)Suggested Settings (9)System Block Diagram (10)Technical Specifications (12)Service Information (12)2IntroductionCongratulations! You are now the proud owner of the Crate FlexWave120/212 three-channel guitar amplifier with advanced digital signal processing (DSP) and Channel Tracking. This rug-ged amplifier combines outstanding features with serious clean and distorted sounds. Digital Reverb, Delay, and Modulation effects provide you with a wide variety of sounds. Crate’s unique Channel Tracking feature automatically stores your DSP settings for each channel to memory. As you switch from one channel to another, the DSP settings for the selected chan-nel are instantly recalled. The supplied three-button footswitch allows you to select channels and change the DSP bank (Bank A/Bank B) by “remote control.” A front panel 1/8" stereoCD input jack allows you to play along with your CD player, MP3 player, or iPod. A rear panel insert jack allows you to add even more effects by connecting an external effect processor. Like all Crate products, your FlexWave120/212 amplifier is designed by musicians and built using only the best components. Extensive testing confirms that this amplifier is the absolute best it can be. In order to get the most out of your new amplifier, we strongly urge you to read this manual before you begin playing.And thank you for choosing Crate.Here are some of the features packed into your new FlexWave120/212 Combo Amplifier:• 120 watts rms power output• 2 x 12" speakerThree-ChannelOperation•Channel—HighG ainChannel—OverdriveChannel—Clean• 3-band EQ on the Overdrive and Clean Channels• Proprietary “Shape” EQ control on the High Gain Channel• DSP Effects including Delay, Modulation, and Reverb sectionsInput• CD• EffectsLoopFootswitchincluded• 3-FunctionjackSpeaker• External• Built-in Chromatic Tuner3Channel TrackingYour Crate FlexWave120/212 gives you the power of Channel Tracking. Once you select a DSP setting for each channel, Channel Tracking stores the settings to memory whenever you change channels. When you go back to that channel, Channel Tracking recalls those DSP set-tings automatically, without changing the DSP controls!For example:• Select the Clean channel. Set the Mod control to “Flanger,” the Delay control to “Medium,”and adjust the Reverb control to your preference.• Select the Overdrive channel. Set the Mod control to “Chorus,” the Delay control to “Slap,”and readjust the Reverb control to a different setting. (The DSP settings for the Clean channel are now saved to memory.)• Select the High Gain channel. Set the Mod control to “Phaser,” the Delay control to “Long,”and readjust the Reverb control once again. (The DSP settings for the Overdrive channel are now saved to memory.)• Reselect the Clean channel. (The DSP settings for the High Gain channel are now saved to memory.)When you reselected the Clean channel, the DSP settings previously stored in memory were automatically recalled. Switch to the Overdrive channel and the DSP settings you just stored are still there. You can change the DSP settings at any time. Once you set the DSP and select another channel, Channel Tracking stores the settings for you. Even when the amplifier is turned off, the DSP settings are stored and recalled the next time you turn it on. That’s the power of Channel Tracking!In addition, each channel has two DSP banks, Bank A and Bank B, when you use the supplied three-button footswitch (see page 8 for more information on using the footswitch). Channel Tracking also remembers which DSP bank was selected for each channel.41. INPUT: Use this jack to connect your guitar to the amplifier by means of a shield-ed instrument cable.2. HIGH GAIN LED: This LED illuminates when the High Gain channel is selected.3. GAIN: Use this control to adjust the amount of distortion for the High Gain channel.4. SHAPE: Use this control to “dial in” the tone for the High Gain channel. Rotatingthis control counter-clockwise enhances the mid frequencies, while rotating it clockwise enhances the low and high frequencies.5. LEVEL: Use this control to adjust the out-put level of the High Gain channel.6. HIGH GAIN/OVERDRIVE: Use this switch to select the High Gain or Overdrive chan-nel. With the switch in the out position, the Overdrive channel is selected. When the switch is pushed in, the High Gain channel is selected. Note: This switch is only active when the Overdrive/Clean switch [13] is pushed in.7. OVERDRIVE LED: This LED illuminates when the Overdrive channel is selected.8. GAIN: Use this control to adjust the amount of distortion for the Overdrive channel.9. LOW: This adjusts the bass frequencies. Use this control to get the best sounding bass response for your instrument when using the Overdrive channel.10. MID: This adjusts the midrange frequen-cies. Use this control to get the best projec-tion and midrange tones for your instrument when using the Overdrive channel.11. HIGH: This adjusts the treble frequen-cies. Use this control to attain a bright and lively sound for your instrument when using the Overdrive channel.12. LEVEL: Use this control to adjust the output level of the Overdrive channel.13. OVERDRIVE/CLEAN: Use this switch to select the Clean channel or the Overdrive and High Gain channels. With the switch in the out position, the Clean channel is select-ed. When the switch is pushed in, either the High Gain or Overdrive channel is selected, depending on the setting of the High Gain/ Overdrive switch [6].14. CLEAN LED: This LED illuminates when the Clean channel is selected.15. VOLUME: Use this control to adjust the output level of the Clean channel.16. LOW: This adjusts the bass frequen-cies. Use this control to get the best sound-ing bass response for your instrument when using the Clean channel.17. MID: This adjusts the midrange frequen-cies. Use this control to get the best projec-tion and midrange tones for your instrument when using the Clean channel.18. HIGH: This adjusts the treble frequen-cies. Use this control to attain a bright and lively sound for your instrument when using the Clean channel.19-21. EFFECTS: Use these controls to apply and adjust the DSP effects. Complete informa-tion on these effects is provided on page 7. 22. CD INPUT: Use this 1/8" stereo mini jack to connect the output from a CD player, MP3 player, laptop, etc., to the amplifier. The signal at this jack is summed into a mono signal, which is sent to the internal power amp circuit. Use the output level con-trol for the signal source to adjust the signal for the proper mix with your guitar.23. POWER: Use this switch to turn the amplifier on (top of the switch depressed) and off (bottom of the switch depressed). The switch illuminates when the amplifier is turned on.5624. FUSE: The fuse protects the amplifier from damage caused by a faulty AC power source or other problems. If the fuse opens, replace it with the same size and type. Iffuses continue to fail, check the AC source. Ifthe source is okay, refer to page 12 or con-tact your Crate dealer for service information.25. EXTENSION SPEAKER: Use this jackto connect the amplifier to an external speak-er cabinet. This jack is wired in series withthe internal speaker, which remains activewhen an extension speaker is connected.26. DSP FOOTSWITCH:Use this jack to connect one of the footswitch cables to the three-button footswitch (sup-plied). This allows you to select between two DSP presets for each of the three channels. Additional information about the operation of the footswitch is on page 8.27. CHANNEL FOOTSWITCH: Use thisjack to connect one ofthe footswitch cables to the three-button foot-switch (supplied). Thisallows you to remotelyswitch between theClean, High Gain, andOverdrive channels.Additional informationabout the operation ofthe footswitch is on page 8.28. INSERT: Use this jack to connect an external signal processor to the amplifier. Use Crate’s STP201, STP202, or STP203 stereo-to-mono Y-cord or an adapter such as Crate’s YPP117 and two 1/4" mono signal cables to connect to the effect, as shown below.29. POWER CORD (not shown): This grounded power cord is to be plugged into a grounded power outlet, wired to current electrical codes and compatible with the voltage, power, and frequency requirements stated on the rear panel. Do not attempt to defeat the safety ground connection!30. ELECTRONIC TUNER (cabinet top) The electronic tuner is active whenever theamplifier is turned on, providing constant “real-time” tuning. The row of red LEDs on the left indicates which note is being tuned. When a single LED is lit,it represents the notethat appears just below the LED. When two LEDs are lit, it represents the note that appears between them in the bottom row. The left green LED indicates the note is flat, and the right green LED indicates the note is sharp. The note is properly tuned when both LEDs are lit at the same time.8Using the Footswitch with the DSPThe Crate three-button footswitch supplied with the FlexWave120/212 allows access to an additional DSP preset for each channel of the amplifier. When the footswitch is connected to the amplifier as shown below, the “original” DSP presets are active for each channel when the #3 footswitch LED is illuminated. These are referred to as “DSP Bank A.” When the #3 button is switched and the LED is off, a second DSP preset may be stored and recalled for each channel — “DSP Bank B.”Note: DSP Bank B presets are only accessible when the footswich is connected to the ampli-fier. When the footswitch is not connected, only DSP Bank A is accessible.LED ON = HIGH GAIN CHLED OFF = OVERDRIVE CH[only when Switch #2 is activated (LED ON)]LED OFF = CLEAN CH EXT DSP CHANNELINSERTFOOTSWITCHSuggested SettingsSweet ‘n Clean:Just a ‘Lil Nasty:Politely Gritty:Down ‘n Dirty:Mean & Obscene:9System Block Diagram10INPUTBUFFERMIX AMPCLEANDAMPING POWER AMPEXT.SPEAKERSPEAKERSINSERTTUNERDSPMIX AMP11This equipment has been tested and found to comply with the limits for a Class B digital device, pur-suant to part 15 of the FCC Rules.

线阵音箱就是线阵列音箱（linearray speaker)。

现实中的线阵列和理论上的线阵列区别在于：高频现实中的线阵列不是单一发出全频的声源，是由高低音单元或者是高中低音单元组成的。

理论上的线阵列每个声源之间的间距最小，现实中的线阵列由于单元尺寸的限制，在高频段无法做到间距最小（声源间距＜重放最低频率的1/2波长），所以现实中的线阵列在高频都是有一个声源转换的波导，把高音单元的圆形出口转换成长条形的出口，在转换的各条路径是接近等距的，这样就解决了高音单元之间间距的问题。

中频和低频现实中的线阵列由多个单元组成，在大型的线阵列音箱中，中音和低音单元有时数量会达到2个或者4个，在双单元或者四单元的结构中，必然存在相同的单元是同一路驱动信号，这时，相同单元之间的间距导致在偏轴存在路径差，从而存在干涉（梳状滤波现象）。

解决的方法有几种：1降低分频点，把此路单元的工作频率限制在梳状滤波的第一抵消频点之下（JBL,VDOSC的做法）。

2 两个单元分开工作频段，在干涉频段只有一个单元工作（MEYER的做法）3 只用一个单元，然后通过号筒提升灵敏度（MARTIN的做法）。

怎么判断线阵列的好坏？这个问题很多人都有自己的答案，最常见的是拿耳朵听。

特别是做惯演出的音响师，绝对相信自己的耳朵！从一个研发工程师和系统工程师的角度出发，可以从以下几点判断：1、看音箱的单元尺寸和分频点这已经可以判断很多信息了，例如，高音如果是用44MM直径的高音，安全的工作频率不能低于2K，如果中音是用4个6寸半的话，你就可以判断这个设计不合理，因为2个6寸半水平间距最小都要超过7寸，7寸的干涉频率最低点是1.34K左右（242公式），那么为了单元的安全，分频点在2K的话，中音在1.34K就会发生干涉，为了不干涉，分频点在1.3K的话，44高音的振膜就很快会碎掉。

所以是完全不合理的设计。

2、看阻抗曲线尤其是低音，如果设计不合理的音箱，阻抗曲线很快就看出来，根据单元T/S参数设计合理的音箱，低频特性不会差，如果阻抗曲线上看出来容积不够，或者是调谐偏低，或者是调谐偏高，或者是有共振，或者是容积偏大，低频都不会好。

设计时主要考虑以下5点：（1）音箱单元和结构的选择；（2）外形尺寸和质量的控制；（3）可以多只音箱并联的阻抗；（4）快速并节约空间的安装运输方式；（5）配套系统机柜的做法。

以上思路均围绕方便流动使用这个中心思想，目的就是让该音箱系统在流动市场上具备强大的竞争优势。

和一般音箱研发者的思路不同，笔者从使用者的角度出发，考虑的不仅是音箱的设计，同时还有该音箱的系统配套。

2 音箱单元和结构的选择在大型流动演出中作为主扩声的音箱，必须保证有足够的声压级，一般须达到139 dB以上的峰值声压级。

而现有的压缩高音单元和动圈低音单元的灵敏度和功率是有一定局限性的，通常能达到较高声压级的高音单元是Φ75 mm（3 in，1 in=2.54 cm）和Φ100 mm（4 in），Φ75 mm的单元一般灵敏度在108～112 dB，功率在75～80 W左右，单只的最大峰值声压级不会超过137 dB，Φ100 mm与Φ75 mm的灵敏度类似，功率在100～150 W左右，单只最大峰值声压级不会超过139 dB。

由于Φ100 mm的单元市场上比较少见，性能比较好的更是凤毛麟角并且极其昂贵，所以不予考虑。

使用2只Φ75 mm的高音单元，即可达到或超过最大峰值声压级139 dB的要求。
