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。

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.
