FLAT-PAK SERIES Model FP-PA20B 20 W 音频功率放大器说明书

FLAT-PAK SERIES Model FP-PA20B 20 W 音频功率放大器说明书

FLAT-PAK™ SERIESModel FP-PA20B Array 20 W Audio Power Amplifier∙20 Watts RMS Constant Voltage Amplifier∙25 V Output∙Maximized Audio Level for Output Power∙Audio Quality Superior to Standard Amplifiers∙Input / Output Terminal Block Connections∙Line Level Balanced or Unbalanced Input∙Integral Audio Compressor to Control Clipping∙High Overall Operating Audio Level∙Peak LED to Indicate Audio Compression∙Ultra-compact All Metal Construction∙Convenience of RDL FLAT-PAKsThe FP-PA20B is part of the group of versatile FLAT-PAK products from Radio Design Labs. The unique FLAT-PAK case can be directly screwed or bolted to cabinets or shelves. Optionally available rack-mounting accessories permit single or multiple FLAT-PAK module mounting.APPLICATION: The FP-PA20B is the ideal choice in many applications where multiple 25 V speakers in a zone need to be powered from a single audio power amplifier.The FP-PA20B features a balanced line level input that may be connected unbalanced. A front panel GAIN control is designed to be adjusted either manually or with a trimming screwdriver. The gain range will accommodate standard unbalanced levels as well as professional balanced levels. A 25 V amplified output is provided to drive corresponding speakers in a distributed sound system.A red PEAK LED is provided to indicate the threshold of the integral compressor. Audio levels that could cause the amplified output to clip are compressed according to two dynamic time constants. Normal audio level signals remain unaffected by the compressor thereby preserving audio dynamics and preventing the compressor from increasing feedback potential when the amplifier is used for paging. The compressor is designed to remain aurally transparent while maintaining clean, unclipped amplified audio for input overloads of up to 20 dB. In addition to the compressor, an active filter circuit prevents saturation of the output transformer at low frequencies. The FP-PA20B produces average audio levels and audio clarity normally expected of amplifiers delivering much higher output power.The durable construction and low profile of the FP-PA20B allow mounting in a wide range of locations not suited to a conventional style power amplifier. Power is provided to the module either through the barrier block or through the DC power jack. For continuous RMS output power, a 24 VDC 2A power supply is required. A 1A supply is sufficient for normal program audio levels and content. Power supplies are sold separately.Wherever a high quality constant voltage audio power amplifier is needed to provide reliability, compactness and unsurpassed versatility, the FP-PA20B is the ideal choice. Use the FP-PA20B individually, or combine itwith other RDL products as part of a complete audio/video system.RDL ∙ 659 6th St. ∙ Prescott, AZ., USA 86301 ∙ (928) 443-9391 ∙ FAX (928) 443-9392 ∙FLAT-PAK ™SERIESModel FP-PA20B20 W Audio Power AmplifierTYPICAL PERFORMANCEInput: Line level (+4 dBu nominal balanced) (-10 dBV nominal unbalanced) Input Impedance: 20 k Ω balanced bridging10 k Ω unbalancedInput / Output Connectors: Plug-in terminal blockGain Adjustment: Single turn audio taperMinimum Input Levels: Balanced: -26 dBu (to cross compressor threshold) Unbalanced: -28 dBV (to cross compressor threshold) Maximum Input Levels: Balanced: +23 dBu Unbalanced: +15 dBV Frequency Response: 50 Hz to 18 kHz (+/- 3 dB)* THD+N: < 0.1% (@ 1 kHz)*< 0.5% (50 Hz to 20 kHz)*Compressor: Threshold 6 dB below rated output, automatic adjusting attack and release Noise: <-80 dB (below 20 W RMS) CMRR: > 55 dB (50 Hz to 120 Hz) Output Power: 20 W RMS @ 25 VAmbient Operating Environment: 0° C to 30° C Maximum; 20° C Recommended Power Requirement: 24 Vdc @ 1650 mA (for continuous RMS power output, Ground referenced) 24 to 33 Vdc @ 1000 mA (for normal program material with minimal compression, Ground referenced) Indicators (2): Red LED: PEAK LED indicates compressor activity Green LED: Power ON*measured at compressor threshold level equaling 4 W RMS output powerOverall Dimensions: Height: 2.30 in. 5.85 cm Width: 3.25 in. 8.26 cm Length: 6.04 in. 15.3 cmInstallation/OperationDeclaration of Conformity available from .

您不仅很快就会熟悉并得心应手的操控他们,而且您还会发现他们所具备的许多创新的性能充分融合了设计师多年的现场调音经验。

如果您再仔细地检查一下他们的质量,您就更会欣赏他们标准化的结构:与我们的旗舰产品ML系列调音台有同样的单独的垂直型电路板,同样的电位器帽,同样的铜质内部耦合界面。

下面的几款PA调音台是带有双功率放大器的型号。

PA12-CP有8路单声道和2路立体声通道输入。

PA20-CP有16路单声道和两路立体声输入。

这两款在侧面均有保护装饰,在前面有便携手提把手。

双功放的配置可以根据现场扩音情况的不同来自由的使用。

例如,您可以用其来做没有返送系统的立体声主扩系统,或是有返送和单声道的系统,再或是与外部功放相连,用这台设备做两个独立的返送系统。

同时也可使用额外的单声道输出用于超低音的信号通道等等。

PA-CP系列的功率放大器是第三代的设计,其在出场之前都是已经做了严格的可靠性和声音质量的测试,其输出功率采用4Ω和8Ωohms可切换式恒定功率设计,功率均为2x500W/8Ω。

精准的均衡调节为音乐的创作和有效的抑制房间声反馈提供很大的方便。

所有输出通道都有四段的参量均衡,每个频段均设置有扫频旋钮,我们是通过理论的分析和实际存在的声染色等问题研究和测试以后,决定设置参量均衡,而不用图示均衡的。

并且我们的“EQ Visualiser”软件将会告诉您参量均衡对频率产生的作用,并可以通过此软件与调音台的MIDI口连接来自定义您所需要的效果。

快速启动1.确保安全:首先要确认设备的工作电压与您当地的供电电压是否一致,检查后面板的ON/OFF是否置于off的状态。

用随机配送的电源线将调音台与电源插座相连接。

在没有检查好所有的连线和控制设置之前不要打开任何开关。

并且要确保在前面和侧面机身的通风口处不要有东西挡住。

功放机按键说明书

功放机按键说明书篇一:音响操作说明音响操作说明针对于本系统,具体操作如下: 1. 话筒及音乐输入连接:调音台可以接入有线话筒、无线话筒、DVD、电脑音频等;有可种可以接入的插口,方便进行连接(如下图所示)。

第1路到第8路一般接入话筒,第13到16路为DVD等音乐信号输入;第9路到第12路比较特殊,即可以接入话筒,也可以接入DVD等音乐信号(已经标明L、R声道),只是接口不一样而已。

注:1、如果上面的卡侬口已经接入设备,就不要再用下面的单插插口,也就是说,这一路里面只可以接入一路音源;下面的INSERT插口,本系统用不到。

2、如果要接入普通的会议话筒,可能需要48V供电,那么本调音台具备此功能,只需要把调音台的48V供电开关打开即可,如下图所示;2. 开启系统:先打开第一台电源时序器,电源时序器会依次给所接设备供电;等第一台电源时序器的8路电源依次打开完毕,再打开第二台电源时序器,同样,等8路电源全部打开方可进行其他操作。

注:专业音响设备具有开关顺序,开启时顺序为:音源设备(如DVD、话筒接收机等)、周边设备(如调音台、均衡器、效果器等)、功放。

否则的话,可能会产生“嘭”的声响,以至于损坏设备。

3. 播放音频、视频:首先把调音台右下角总音量的推子调整到合适的位置(如图一所示),高度最好不要超过0刻度;然后打开DVD 机,把光盘放入,让DVD处于读碟播放状态;找到调音台对应DVD接入的那一路,把方块透明的开关按钮按下,使其处于点亮状态,再按下下方的红色ST按钮;然后轻轻从下方往上推长方形的音量推子,直到音量足够为止(如图二所示)。

高中低音调整:正常情况下,无需调整音乐音频,因为DVD或电脑放出来的都是原始音频,如果想调整音乐的高中低音,可以通过调音台自带的简单均衡器进行调整(如图三所示),上面的为高音旋钮,中间的为中高频旋钮,下面的为低音旋钮。

音视频矩阵切换:如把第1路音频、视频切换到第2路输出,那么操作方法是:按AV键然后从右侧上边的一排(输入键)按下1键,然后再从下面一排(输出键)按下2键,最后再按下ENTER 键即可。

Damage caused by connecting the amplifier to improper AC voltage is not covered by the three-year US warranty.Make sure the power switch is off before making any input or output connections.It is always a good idea to have the gain controls turned down during power-up to prevent speaker damage if there is a high signal level at the inputs.CONNECTING INPUTSInput connections are made via either the 3-pin XLR -type connectors (Figure 1) or 6.3 mm sockets on the rear side of the amplifier.CONNECTING OUTPUTSLoad can be connected using banana plugs or spade lugs. A black binding post is considered “COM”, while the three red binding posts are considered “hot”, and the voltage is 38V (different from the model ), 70V , and 100V .Note:Never connect the “hot ”terminals together.When connecting load (speakers ), it is better to use one pair of output terminals only. If the PROT Led goes on steadily while power has been turned on and signal has been fed, there must be a trouble of output shorted. Please turn the unit off and correct the trouble then turn it on again.Figure 1 3-pin XLR-type connectorsSPECIFICATIONSHTTP://DSPPA ACOUSTIC TECHNOLOGY CO., LTD.使用说明欢迎惠顾。

要,即使广播服务区是写字楼,也不应把本底噪声估计得太低。椐此,作为一般考虑,除了繁 华热闹的场所,不妨大致把本底噪声视为65~70dB(特殊情况除外)。照此推算,广播覆盖区的 声压级宜在80~85dB以上。
鉴于广播扬声器通常是分散配置的,所以广播覆盖区的声压级可以近似地认为是单个广播 扬声器的贡献。根据有关的电声学理论,扬声器覆盖区的声压级SPL同扬声器的灵敏度级LM、馈 给扬声器的电功率P、听音点与扬声器的距离r等有如下关系:
这里所说的公共广播是指有线传输的声音广播,通常用于工厂、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,通常按 下列顺序进行: 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
2、 广播扬声器的选用和配置

Caspian 单声道后级普通接法、双线分音、双功放、三功放接线示意图:
功放的电源开关平时应处于接通状态,如果长期不用的话,请关闭电源开关并拨掉电源线。

功放背后的“讯号串接输出端子”作用是:当前级没有足够多的输出端子、但又要同时接多台后级时,可以通过该端子将讯号不经放大直接输给其他后级。

接通电源开关后,功放经过短暂的自检后将进入工作状态,这时前面板的指示灯为红色,功放可以自由识别有无讯号输入,当无讯号输入状态超过2分钟后,功放的显示灯自动转为
待机状态,显示灯变为绿色;但只要一检查到有讯号输入,功放即回复到正常的工作状态,显示灯也将转回红色。

这项功能既使功放能立刻进入状态,又免除了开关机的麻烦。

当功放处于待机状态时,如果侦测到异常情况,例如过流、短路,它就会立即启动自我保护装置,并且显示灯会不断闪烁提醒使用者的注意,你只要关一下机器,就可以使它回复正常的工作状态。

OPERATING PRECAUTIONS
Make sure the AC main voltage is correct and is the same as that printed on the rear of the amplifier. Damage caused by connecting the amplifier to improper AC voltage is not covered by the three-year US warranty.
Make sure the power switch is off before making any input or output connections.
It is always a good idea to have the gain controls turned down during power-up to prevent speaker damage if there is a high signal level at the inputs.
CONNECTING INPUTS
Input connections are made via either the 3-pin XLR -type connectors (Figure 1) or 6.3 mm sockets on the rear side of the amplifier.
CONNECTING OUTPUTS
Load can be connected using banana plugs or spade lugs. A black binding post is considered “COM”, while the three red binding posts are considered “hot”, and the voltage is 38V (different from the model ), 70V , and 100V .
Note:
Never connect the “hot ”terminals together.
When connecting load (speakers ), it is better to use one pair of output terminals only. If the PROT Led goes on steadily while power has been turned on and signal has been fed, there must be a trouble of output shorted. Please turn the unit off and correct the trouble then turn it on again.

操作注意事项
电源电压应确实与本机相符,由电压不符造成的损坏不在保修之列。

所有输入输出连接好以前,不要通电;通电前最好把音量调至最小以防损坏扬声器。

当通电并输入信号後,如果保护指示灯(PROT)点亮,即说明有输出短路故障.应即切断电源,排除故障後重新加电.
输入之连接
所有输入均应连接於机器後面板之卡隆插口(图1)或6.3 mm 插口。

输出之连接
输出端子在後面板,可用香蕉插或铲形插连接。

黑色乃公共端,红色乃热端。

通常应使用“定压”端子输出,此 时各个扬声器应带线间变压器,扬声器的总功率应与功放的额定输出功率相当。

扬声器在近距离配置时也可用“定阻”(4~16Ω)端子输出,相应地此时扬声器的总阻抗应为4~16Ω。

注意:
宜只选用一对输出端子;
任何时候都不应把两个“热端”连接在一起。
