Over the past decade, the sound of Lab.gruppen ampli- fiers has earned praise from renowned FOH engineers and owners of the world’s premier sound rental companies. At the core of the C Series high-power* model’s tight and transparent sound is patented Class TD technology. As a proprietary implementation of tracking Class D, Class TD approaches the exceptional efficiency of Class D while retaining the superior sonic quality of the best Class B output stages.A Regulated Switch Mode Power Supply (R.SMPS) contributes to the remarkable efficiency of the C Series high-power models, while at the same time providing stable operation even with wide fluctuations in mains voltage. R.SMPS also works in conjunction with Class TD to give extraordinary power density. More channels with more power are condensed into a smaller package, allowing C Series amplifiers to minimize rack space requirements and reduce installation costs. Extreme power density demands efficient cooling, and here Lab.gruppen’s Intercooler® proves remarkably effective. Thousands of small copper cooling fins dissipate heat, and all output devices are mounted on one row perpendicular to airflow for uniform cooling.C Series amplifiers are uniquely capable of adapting to a wide variety of demanding load conditions. Each channel has an individually configurable Voltage Peak Limiter (VPL), which allows the output to be optimized for any loudspeaker load – whether one massive subwoofer or a series of small 100 V loudspeakers. VPL works in combination with adjustable input gain to achieve maximum headroom regardless of input levels or output impedances.To assure reliability, and minimize service interruptions, C Series amplifiers offer comprehensive warning and protection features. Whenever faulty wiring, improper use, or extreme ambient tempera-tures threaten trouble, a C Series amplifier gives clear and accurate warning indications. Protection measures are inserted only when dangerous thresholds are passed. Conditions are re-checked at six-second intervals, and normal operation resumes when measure-ments return to nominal.Every C Series amplifier is ready for the NomadLink® network right out of the box. With NomadLink®, key amplifier parameters are displayed via DeviceControl software, and remote control of chan-nel mutes and power on/off is under network control. (NomadLink®requires the separate NLB 60E NomadLink®Bridge & Network Controller.)▸▸Auditoriums▸▸Performing▸Arts▸Centers▸▸Convention▸Centers▸▸Stadiums▸and▸Arenas▸▸Theme▸Parks▸▸Hotels▸▸Houses▸of▸Worship▸▸Restaurants▸▸Clubs▸▸Educational▸Establishments▸▸Boardrooms▸▸Museums▸▸Offices▸▸Shopping▸Malls▸▸Transportation▸Facilities Applications* C Series high-power models are:C 88:4, C 68:4, C 48:4, C 24:4 and C 16:4 C 68:4L a b .g r u p p e n a b ▸ S w e d e ni n t e r n a t i o n a L c o n t a c t ▸ i n f o @L a b g r u p p e n .c o m | u S & c a n a d a c o n t a c t ▸ i n f o @t c g -a m e r i c a S .c o mw w w .l a b g r u p p e n .c o mSpecifications C 68:4Item no.

VARIATIONSAlthough the description above is for combining TWO SERIES PAIRS in a PARALLEL hook up,you may also select to combine a SERIES PAIR and a PARALLEL PAIR in a PARALLEL hook up.Simply be sure you have properly calculated the total impedance,and connect the (+)speaker circuit wire to the proper amp terminal.For example,if you use a SERIES PAIR of 8-Ohms speakers (the total impedance is 16ohms)and a PARALLEL PAIR of 8-Ohms speakers (the total impedance is 4ohms)in a PARALLEL hook up,the TOTAL IMPEDANCE of this system is 3.2OHMS,so you should connect the (+)speaker circuit wire to the 4-OHM terminal.System 4:Four speakers in series/parallel combination1.Group the four speakers into two pairs.2.Connect each pair of speakers in SERIES (see system 2above).If you connect 8-ohm speakers,the total impedance of each pair is 16ohms.3.Connect the two pairs of speakers in PARALLEL,If you connect 8-ohm speakers,the total impedance of both pairs is 8ohms.Note:If each of the four speakers is 8ohms,the total speaker impedance of the combined series/parallel connection described above is also 8ohms.Likewise,the total speaker impedance is 4or 16ohms,if the speakers are 4or 16ohms respectively.See the chart below for some samples system suggestions:COMBINATION OF ONE SERIES PAIR AND ONE PARALLEL PAIR IN PARALLELSERIES TO ONE PARALLEL TO ONE TOTAL IMPEDANCE Use this SPEAKER PAIR

In this case,4-Ohm terminal is used your system impedance may be varied depending on the impedances of the individual speakers,and may reguire hook up to the8or16Ohms terminal.System5:Connecting speakers with transformers 1.Locate the input taps on your transformer.These taps are on side of the transformer,and are rated in watts, 10,5,2.5,ually,each speaker in a system uses the same wattage tap.Connect the selected tap to the amplifier70V RMS terminal.If you wish a particular speaker to have a higher volume level,connect the wire from70V RMS to a higher wattage tap on the transformer.2.Connect the transformer's COMMON tap on the primary side to the amplifier COMMON terminal.3.Connect the speaker's(+)terminals to the transformer's secondary tap that matches the speaker's TOTAL IMPEDANCE.Locate on the opposite side of the transformer,these secondary taps are outputs,and are rated in Ohms4,8or16.4.Connect the speaker's(-)terminals to thetransformer's COMMON tap on the secondary side. NOTE:Before connecting the speakers,please be sure the total wattage of the primary tap you use doesnot exceed the amplifier's maximum power rating,PA10520W and PA20540W.ALSO:Avoid,where possible,multiple connections to the70V RMS and COMMON terminals.Using headphonesTo listen privately,or to monitor sound sources, connect a pair of low impedance stereo headphones (not supplied)with6.35mm plug into the PHONES jack on the amplifier front panel.Please listen safely.Follow these recommendations: Do not listen at extremely high volume levels.Extended, high-volume listening can lead to permanent hearing loss.Always start with the volume control set to a LOW level BEFORE you put the headphones on.Then gradually increase the volume as necessary.Connecting to standard AC powerAfter making all other connections,set the POWER switch to OFF position.Then connect the power cord to a standard AC outlet. Connecting to4A/12V DC power(PA105)You can power the amplifier from your vehicle's12-volt battery.Connect the supplied DC power cable's barrel plug to DC12V IN jack on the amplifier,and then connect the cable's other end to the12-volt accessory socket on the vehicle,such as the cigarette-lighter socket. CAUTIONS:PLEASE UNPLUG THE AC POWER CORD BEFORE CONNECTING THE DC POWER CABLE FOR THIS12V POWER USAGE,AND DISCONNECT THE DC POWER CABLE BEFORE PLUGING IN THE AC POWER CORD FOR AC POWER USAGE.THE VEHICLE USING FOR THIS POWER SOURCE MUST HAVE A NEGATIVE GROUND ELECTRICAL SYSTEM.IF YOU ARE NOT SURE OF IT,PLEASE CHECK WITH YOUR VEHICLE'S DEALER.Turning the amplifier on1.Turn on the audio input source equipment which is connected to the amplifier INPUT jack.2.Set all volume levels(MASTER,MIC1,MIC2,and PHONO/AUX)to their minimum level settings.3.Press the power switch to turn the amplifier on.4.Adjust the controls of MIC1,MIC2,and PHONO/AUX to the achieve desired volume and balance.Using the LED power meterThe meter LED position indicate the amplifier output power.Using the MASTER volume controlThe MASTER volume control increases or decreases output level gain.To obtain best performance with the least distortion, be sure to adjust the output level so that the LED meter does not continuallyexceed the right extreme of the meter's range. CAUTION:Setting output level too high can overdrive the amplifier,causing permanent damage.Using the MIX BUS jackYou can connect another PA105/PA205to this jack to double the size of your PA system.This lets you use up to four microphones and two turntables(or two auxiliaryies)sound souces. Use a shield cable with phono plugs at each end,and connect the cable between the MIX BUS jacks on the back of two amplifiers.For the best results,do not use a cable longer that6 feet.SpecificationsOutput Power at THD10%,1kHz......................................20W(PA105)/40W(PA205) Maximum Power....................................80W(PA105)/120W(PA205) THD at1W,1kHz Low-Pass FilterMIC1...................................................................1% MIC2...................................................................1% AUX/CD..............................................................1% PHONO...............................................................1% Frequency Response(at1W,+/-3dB)MIC1.................................................80Hz-20kHz MIC2.................................................80Hz-20kHz AUX/CD............................................80Hz-20kHz PHONO(RIAA100Hz/10kHz)......+13dB/-13.5dB Input Sensitivity(at10%THD,1kHz)MIC1.............................................................2.5mV MIC2.............................................................2.5mV AUX/CD.........................................................150mV PHONO...........................................................3.5mV Signal-Noise Ratio(Input Shorted)with WTD MIC1................................................................60dB MIC2................................................................60dB AUX/CD...........................................................70dB PHONO............................................................60dB Noise Level(Input Shorted)..............................0.75mV Tone Control(PA105)-15dB(High Cut at10kHz)Equalizer Control Range(PA205)100Hz.......................................................+/-10dB 1kHz.........................................................+/-10dB 8kHz.........................................................+/-10dB Power Requirement120V AC,60Hz/240V AC,50Hz4A12V DC(OPTION OF PA105)Power Fuse120V AC........................1.2A(PA105)/1.5A(PA205) 240V AC......................0.6A(PA105)/0.75A(PA205) Dimensions H x W x D,31/3x123/4x89/10(inches)85x324x226(mm)Weight,(kg)(PA105)3.56kgs/(PA205)3.92kgsPYRAMID AMPLIFIERS CAR AMPLIFIERS。

功率放大器(PA)偏置详细解读(三)
功率放大器（PA）偏置详细解读（三） 在本系列的前面已经描述了如何成功地偏置射频（RF）功率放大器（PA）。
为攻克RF PA依赖温度的非线性难题，需要一种监测与控制解决方案。
通过动态控制PA的栅极电压以维持所需的漏极电流（IDSQ），自动化监测与控制（AMC）解决方案就能克服非线性方面的困难。
本系列第1部分和第2部分所提的电流和温度检测解决方案包括好几种组件：模数转换器（ADC）、数模转换器（DAC）、精密参考、电流检测放大器和温度传感器。
无线基站、微波回程等许多应用均能从采用集成式器件（需要较少的电路板空间）的较简单解决方案那里大获裨益。
下面让我们来看看采用集成式器件、适用于RF基站的AMC解决方案的实施。
AMC7834包含能让并行PA运行的一路多通道ADC输出和几路DAC输出。
其它集成式组件包括高侧电流检测放大器和可选的DAC双极性范围器件。
双极性范围能支持各类PA技术产品的并行运行，例如：用一个DAC对横向扩散金属氧化物半导体（LDMOS）PA进行偏置，同时用另一个DAC对氮化镓（GaN）PA进行偏置。
您可使用这些块来创建电流或温度检测解决方案，如图1所示。
图1：用AMC7834进行电流和温度检测 用AMC7834进行电流检测 当把AMC7834器件放入这种配置结构（见图1）时，整个检测电阻器（RSENSE）上的差分电压会被输入到内部高侧电流检测放大器的检测引脚。
在内部将该差分电压转换为电流值。
如果把该AMC设置为闭环运行，就能不断更新DAC输出，从而将DAC输出调节成预编程的IDSQ值。
图2展示了这一切。
还可以把AMC7834设置为开环运行，那样您就能用接口将微控制器与该器件相连接，以获得通过该检测电阻器看到的IDSQ值。
另一种选择是把该信息用于跟踪或校准目的，或当调节DAC输出时在规定的算法中使用它。

一、描述
PA07是一个高电压、大输出电流的运算放大器，用于驱动电阻、电感和电容负载。
为了获得最佳的线性度，特别是在低电平时，使用热敏电阻补偿的基极-发射极电压倍增器电路对A/B 类放大器操作的输出级加有偏置。
热关闭电路防止过热，并将异常工况下散热器的要求降到最低。
用户可以通过观察到所有工作条件下的安全工作区(SOA)，来选择可编程的限流电阻。
两个放大器内部补偿所有增益设置。
对于连续负载下运行时，建议安装适当额定值的散热器。
这种混合电路采用厚膜电阻(金属陶瓷
)、陶瓷电容器和半导体芯片，以最大限度地提高可靠性、最小尺寸和最高性能。

四、典型性能图表
五、安全工作范围（SOA）
大多数功率放大器的输出级有三个明显的限制：
1、电流输出能力的导电线的绑定。
2、当集电极电流和集电极-发射极电压超过规定限制时，就会发生二次
击穿效应。
3、集体管输出级的结温。
SOA图表曲线结合了这些限制的影响。
对于给定的应用，输出电流的方向和大小应该根据SOA图表曲线进行计算或测量并检查。
对于电阻性负载很简单，但是对于电抗性负载和（EMF）电动势产生的负载则更复杂。
但是，以下准则可以节省大量的分析工作。
1.对于DC输出，特别是由故障条件导致的输出，请根据SOA图检查最坏
情况下的电压级别。
确保负载线不超过0.5ms的限值，其他任何第二断层线的行程不得超过时间标注，占空比不超过10%。
有意的典型分析非常有用，因为硬件设置经常需要具有广泛共模抑制范围的仪器或放大器。
有关SOA注意事项的详细信息，请参阅应用部分注释AN01和AN22。
2.放大器可以处理任何无功或电动势产生的负载和电源线短路，或者如果
电流限制设置为T C = 85℃，则放大器可以处理常见的短路:
在使用特定应用操作条件进行进一步分析时，可以超越这些简化的限制。
3.输出级加有保护，不会有瞬态反激。
然而，为了防止持续的、高能量的
反激，应该使用外部快速恢复二极管。
六、一般说明
请阅读应用注释1“一般操作注意事项”，其中包括稳定性、供电电源、散热、安装、电流限制、SOA解释和规范解释。

七、典型应用
位置是由差分连接的光电二极管感知的，这种方法可以抵消光学元件的时间和温度变化。
偏离中心位置产生的误差电流被运放电路调整，驱动系统回到中心位置。
当两个二极管都处于黑暗状态时，瞬间开关触点使系统脱离锁定，然后集成电容保持驱动电平。
当下一个指标点到达时，C L和R L的超前网络通过减少超调来优化系统响应。
PA07极低的偏置电流增强了积分器电路的性能。
图16：典型应用
注解: 否定光电不稳定性;引入网络最小化超调;连续的位置控制。
七、过热保护
当衬底温度超过150℃时，热保护电路将关闭放大器。
这使得散热器的选择可以基于正常的工作条件，同时保护放大器在临时故障条件下不超过高的结温。
热保护是一个动作相当慢的电路，因此不能保护放大器免受瞬态SOA 破坏(TC = 25°C边界以外的区域)。
它的设计是为了防止短期故障条件，导致高功率损耗的放大器。
如果不消除引起热关闭的条件，放大器将在关闭时振荡。
这将导致高峰值功率加重，将破坏信号的完整性，降低设备的可靠性。
八、电流限制
正确的操作需要使用两个电流限制电阻，如外部连接图所示。
R CL的最小值是0.12Ω;然而，为了获得最佳的可靠性，它应该设置得尽可能高。
有关当前限额调整的详细信息，请参阅应用程序注释1和注释9。
R CL(Ω)=0.65V/I LIM(A)
