PA中文说明书
ALLEN&HEATH PA系列使用手册PA系列混音器可提供一个标准的PA系统需要的所有音频信号处理工具，并使您的操控能够做到“随心所欲”。
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。
DSPPA广播系统说明书
【（1）、投标综合说明】DSPPA公共广播系统设备一、公共广播系统概述二、DSPPA 公共广播系统器材性能介绍三、厂区的公共广播/背景音乐示意四、厂区的公共广播/背景音乐示意一、公共广播系统概述DSPPA 广播音响系统涉及面很广，从工厂、学校、宾馆、车站、码头、广场 到会场、影剧院、体育馆、住宅小区等无不与之有密切关系。
在民用建筑工程设计中，广播系统可分为以下几类： 面向公众区（广场、车站、码头、商场、餐厅、走廊、教室等）和停车场等的公共广播系统。
这种系统主要用于语音广播，因此清晰度是首要的。
而且，这种系统往往平时进行背景音乐广播，在出现灾害或紧急情况时，又可转换为紧急广播。
面向宾馆客房的广播音响系统。
这种系统包括客房音响广播和紧急广播，常由设在客房中的床头柜放送，客房广播含有多个可供自Public Address System公 共 广 播 系 统由选择的波段，在紧急广播时，客房广播即自动中断，自动切换为紧急广播。
以礼堂、剧场、体育馆为代表的厅堂扩声系统。
这是专业性较强的扩声系统，它不仅要考虑电声技术问题，还要涉及建筑声学问题。
两者都要统筹兼顾，不可偏废，这类广播系统往往有综合性多用途的要求，不仅可供会场语言扩声使用，还常用于文艺演出等，对于大型现场演出的音响系统，电功率少则几万，多的达数十万瓦，故要用大功率的扬声器和功率放大器，在系统的配置和器材选用方面有一定的要求，同时应注意电力线路的负荷问题。
面向会议室、报告厅等的广播音响系统。
这类系统一般也是设置成公共广播提供的背景音乐和紧急广播两用的系统，但因其特殊性故也常在会议室和报告厅单独设置会议广播系统。
对要求较高或国际会议厅，还需另行设计诸如同声传译系统，会议表决系统以及大屏幕投影电视等的专用视听系统。
从上面介绍可知，对于各种大楼、宾馆及其他民用建筑物的广播音响系统，基本上可以归纳为三种类型：一是公共广播系统（Public Address System简称PA），这种是有线广播系统，它包括背景音乐和紧急广播功能，通常结合在一起，平时播放背景音乐或其他节目，出现火灾等紧急事故时，转换为报警广播。

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

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。
功放机说明书
功放机说明书篇一：功放的说明书说明书一、面板布置：1、本功放由功放、播放器、电平指示器、扬声器四个模块组成。
其中功放有放大音频信号的功能，可把播放器音频、外接音频、话筒音频信号放大，通过调节旋钮可改变信号的大小。
播放器有读取内存卡里的音频文件并转化成音频信号（另有收音机功能）的功能。
电平指示模块是通过计算音频信号，获取音频里音调的高低信号，再通过led灯显示出来，具有装饰的功能。

2、通电时最好不要触碰变压器和变压线。
3、使用时禁止触碰散热器、变压器，防止因温度过高而烫伤。
4、当使用耳机听音频时，只需把耳机插入耳机插孔，但要注意，在使用耳机之前要控制好音量，防止音量过大而损坏耳机。
一般操作是先把音量调为最小，插入耳机后再慢慢增大。
二、使用步骤：1、打开电源：在打开电源前先把音乐音量，话筒音量④调为最小，并确定自带播放器开关⑥处于关闭状态。
然后把电源线接电，则电源指示灯会亮①。
2、接音频：音频有两种，一种是外接音频输入②，另外一种是自带播放器输入，其优先级是外接音频输入高于自带播放器音频输入。
（1）外接音频输入需用一根3.5mm音频线与外界播放器连接，另外一端必须接到功放的外接“音频输入”②插孔，注意播放器的音量③应适当,否则将会烧坏功放芯片和损坏喇叭。
（2）自带播放器输入：首先把优盘或sd卡插入相应位置11、12、13，然后把播放器开关打开⑥，启动自带播放器。

Balanced Line InputBalanced line level signals connect to the (+), (–), and (G) terminals. If you are connecting an unbalanced line level input, tie (short) the (G) and (–) terminals together. If transformer isolation is required for Input 1, contact Atlas Sound for details. Note: The Balanced Line Input and the Unbalanced RCA Inputs are electrically isolated from each other and can be used at the same time.2. Unbalanced Stereo RCA InputInput 2 consists of stereo summing inputs, suitable for connection to the output of CD/DVD players, etc. Note: The Balanced Line Input and the Unbalanced RCA Inputs are electrically isolated from each other and can be used at the same time.3. 70.7V / 100V Speaker OutputFor loudspeaker connections, follow the labeling paying special attention to the polarity or proceed to the Limit LED & Load Considerations section. Note: Do not short the terminals together or damage may occur. It is recommended to use class 3 rated, 16-gauge wire or higher for speaker wiring.4. Global IEC AC Mains Power ReceptacleThe PA Models support global power sources from 100V-240V 50/60Hz. The package contains a cord that has an international IED connector to a 120V USA type plug. It may be necessary to replace the removable power cord to meet your AC Mains plug type used in your country. Note: It is not required to change the fuse for the different AC Mains voltages.Wiring the PA40G / PA60GSpeaker Outputs - Use 2 conductor unshielded wire of the appropriate gauge. If you are unsure about this, contact Atlas Sound Tech Support at 1-800-876-3333. Make sure you know how many speakers you need and what tap value you intend to use.It is recommended to use class 3 rated, 16-gauge wire or higher for speaker wiring.Balanced Line Input - 2 conductor with shield for low level signals of 20 - 22-gauge is best. Maintain the proper polarity, + to +, – to – , and shield to ground.Unbalanced Input - Pre-made RCA cables can be purchased from vendors to simplify interconnection to external devices.4123In order to prevent unauthorized operation of the PA40G & PA60G, optional security covers are available which take the place of the front panel knobs. After the PA amplifier has been installed and is operating as desired, grasp the front panel knobs and pull straight out from the front panel. Replace the knobs with security covers, Atlas Sound part number MPVCC-5, available in quantities of 5.Rack Mount Kit OptionsThe PA40G & PA60G can be rack mounted as a single unit or with two units together. To do so a PA702RMK Rack Mount Kit needs to be purchased from Atlas Sound.Limit LED and Load ConsiderationIf the Red Limit LED illuminates, the amplifier has sensed an improper load or the input signal is too high, triggering the protection circuitry. When the load sense Limit circuitry is engaged the amp will operate but at a lower power output. It is highly recommended to discontinue use immediately and correct the fault condition. If you continue to operate with the RED Limit LED on, the second stage of the current sense circuit may engage causing the amp not to pass any signal. To reset the amp turn down the Level controls and turn the power off for 10 seconds.In most situations when the Limit LED is in the illuminated steady state it means the speaker system load to the amp is lower than what the amp is rated. This usually is detected when the system is first set up. Below are a few load conditions to check for if the Limit LED is on.1. Connected to the wrong speaker terminal. Always check the speaker terminal to the type of load you are using. Example: If you are installing a 70V or 100V system make sure the wires are connected to the 70V/100V and common (COM) terminals.2. Too many speakers connected to the amp. This is a very common mistake. If you are using a 60W amp and using the 70V speaker terminals, add up the number of speakers and their wattage selections at the speaker. If they exceed 60W you must retap the speakers or remove the correct amount speaker wattage until the wattage is 60W or less. Example: If you are using a 30W tap you can only connect 2 speakers to the amp. If you are using the 7.5W tap, you can connect 8 speakers. If you have too many speakers on the amp it will load the amp down, causing excessive current demand and will trigger the Limit & Protect circuit.3. Wrong speaker tap selection. It is also common in a 70V or 100V system that one of the speakers are set too low of animpedance (8 ohm) and not a 70V or 100V tap. Note: It only takes one speaker to load the amp down incorrectly.4. Short in system. This is common if the wire is run in metal conduit and the wire got nicked during the wire pull.5. Speaker Level Controls. If an L-pad or stepped attenuator is wired wrong it can also load a system down.Front Panel KnobSecurity CoverFront Panel Knob Security Coveror– 9 –Specifications are subject to change without notice.PA40G / PA60GCommercial Amplifiers1601 Jack McKay Blvd. • Ennis, Texas 75119 U.S.A.Telephone: 800.876.3333 • Fax: 800.765.3435Measuring Speaker LoadsBelow is an Impedance load chart for the PA40G and PA60G. Measure the load impedance prior to connecting the load to theamplifier. The enclosed load chart will provide the information to determine if the load or speaker system impedance is too low for the amplifier’s rating. In every install it is always recommended to measure the load prior to turning the system on to be sure the system is installed correctly.Measuring a Speaker System’s ImpedanceNote: It is important to only use an Audio Impedance Meter and not a conventional Volt/Ohm meter. A true audio frequency impedance meter is essential for reliable installation of background music and paging systems in residences, office buildings and public areas. Avoid costly service calls and amplifier damage by verifying actual speaker system impedance prior to operation. Unlike conventional volt/ohm meters, which measure DC resistance, an Audio Impedance Meter unit utilizes an internal frequency oscillator to measure true impedance. It may also be utilized with 70.7V and 100V speaker line transformers, L-pads and matching impedance volume controls. There are several Audio Impedance meters on the market, if you need to buy one we suggest going to MCM Electronics, Parts Express or search the internet for “Audio Impedance Meter”.Measuring 70.7V or 100V Distributed Speaker SystemsLarge distributed systems typically utilize 70.7V (North America) or 100V (Europe) type system to greatly ease the connection of multiple speakers and facilitate long cable runs. Shown below are speakers connected in parallel with wattage ratings to calculate the overall load of the system. Connecting an Audio Impedance Meter to a speaker arrangement such as this will provide the overall impedance of the system.Using the following formula you can calculate the load impedance from the speaker selected wattage. The accumulative wattage of the speaker system must not exceed the maximum wattage output rating of the amplifier or damage may occur. In this example the measurement for a 70.7V design with three speakers of 15W each. The system impedance would measure close to 111Ω. Formula 70.7V x 70.7V = 4998, 4998 / 45W = 111Ω. The amplifier power requirements would be at least 60W for the system to operate properly. Note: It is always recommended to use a larger amp than needed with power headroom of at least 25%. Calculate the load impedance and compare it to the meter’s audio impedance reading. Note: They will never be the same due to the additional wire impedance, but if they are within 10% of the maximum impedance rating or if the impedance is higher than the maximum rating, proceed connecting the load to the amplifier. If they are not recheck your speaker taps or check for shorts.PA40G & PA60G Max Load ChartSpeaker Selection PA40G PA60G70.7V 125 Ohms 83 Ohms 100V 250 Ohms 166 OhmsPA40G / PA60GCommercial Amplifiers1601 Jack McKay Blvd. • Ennis, Texas 75119 U.S.A.Telephone: 800.876.3333 • Fax: 800.765.3435SpecificationsTypeC ommercial AmplifierSafety Listings TUV UL60065 Standard, CE, Class 3 RatedElectrical SpecificationsPower Output PA40G: *********(125Ω), 40W @100V (250Ω) PA60G: *********(83Ω), 60W @ 100V (166Ω)Front Panel Indicators Power, Limit, Signal Controls Input 1 GainTechnical Data Frequency Response 50Hz - 20kHzThd+N .5% or Less @ 1kHz, Rated Output Sensitivity Line Input 500mv (600Ω)Inputs 2 / 3 RCA 500mv (10k Ω)Output Regulation Less Than 2dB, No Load To Full Load Signal To Noise Ratio Balanced Input = >55dBUnbalanced RCA Summed = >55dBPower Requirements Power Consumption PA40G: Idle: 0.075A, 8W, 27 BTU Average: 0.26A, 24W, 81 BTU Max: 0.8A, 71W, 242 BTU PA60G: Idle: 0.075A, 8W, 27 BTUAverage: 0.41A, 34W, 116 BTUMax: 1.25A, 102W, 348 BTUFuse PA40G: T630mA PA60G: T1AMechanical Dimensions 8.5" x 1.75" x 7.81" (216mm x 45mm x 198mm)Weight PA40G: Net Weight = 2.9lbs.

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 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 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。
