产品品牌:QSC
产品型号:RMX2450
品牌: QSC 型号: RMX-2450QSC 推出的全新RMX系列功放,具有专业质量性能及更经济的价格。该系列现有七种型号,它们的功率范围在负载阻抗为2欧姆时,每声道功率从430W到2500W。各型号功放的机体尺寸紧凑,高度仅2U,深度不足16英寸(40公分)。RMX功放具有一组完整的特点:XLR及1/4平衡输入和接线柱输出使用户可方便地选择连接方式,用户可选的削波限制器及低频滤波器时声音效果达到最优化。特 点1) 机体尺寸紧凑,在2U空间中输出功率可达到2500W。2) 专业质量性能-体现了已被证实的QSC的成功设计。3) 大电流环形变压器使2欧姆负载输出功率更高,噪音更低。4) 用户可选的削波限制器可将低失真。5) 接线柱及Neutrik Speakon输出端子。6) 可选低频滤波器(30Hz或50Hz)能保护扬声器,并提高峰值功率余量。7) 1/4(6.3mm)TRS平衡插孔,XLR插头和条型端子输入。8) 前面板上装有各路增益控制,易于操作。9) 信号和削波发光二极管指示灯可监视功放的工作状态。10) 每声道独立的直流电源保护和热过载保护能自动地保护功放和扬声器。削波限制器当RMX功放驱动困难时,削波限制器自动地找到过载点的确切位置,并使功放在其峰值区域保持工作并在不影响效果的情况下防止音质严重失真。低频滤波器和削波限制器均可在各声道独立调节。输入滤波器通过使功放和扬声器频带范围的匹配提高系统的响应能力.防止扬声器低频段音质混浊不清。每个声道单独可调:采用最小型的全频带扬声器是为50Hz;采用次低音扬声器和大型全频带系统是为30Hz;采用录音棚监听时关闭。RMX2450 技术参数:500/8 750/4 1200/2 2400/桥接4 PowerAmplifier(1200Watts)Independentdefeatablecliplimitersreducedistortionwithoutsacrificingpeakperformance.2Urackspace.ThenewRMXSeriesamplifiersgiveyouclean,dynamicpowerwiththelegendaryQSCsoundqualityandreliabilitythatprosdependon.TheRMXSeriesdeliversunmatchedperformanceatanewbreakthroughprice.MuscularPowerPlantThepowersupplyistheheartofanamplifier,convertingrawACpowerfromthewalltocleanDCfortheaudiocircuitry.TheRMXusesapowerfulhigh-currenttoroidaltransformerandamplefiltercapacitancetoensuregenerousenergyreserves.Thismakesacriticaldifferenceinsoundquality,allowingtheamptoeffortlesslypunchouthigh-leveltransients,evenwhendrivingabusive2- speakerloads.SuperiorPerformanceRMXamplifiersdelivertruestudio-qualitysound.Afull,complementaryoutputcircuitusingthehighest-gradelinearoutputdevicesdeliversultra-lowdistortion( 0.05%THD)andaruler-flatfrequencyresponse.SMT(SurfaceMountTechnology)triplessmall-signalcomponentdensity,enablingustopackupto2400wattsofpowerinachassisonly2rackspacesandlessthan16in.deep.Andunlikeotherdesigns,RMXoutputdevicesaredirect-mountedtotheheatsinkforoptimumthermalcouplingandcooling.FeaturesTheRMXSeriesispackedfullofprofessionalfeaturesthatincreaseperformanceandflexibility:Independentdefeatablecliplimitersreducedistortionwithoutsacrificingpeakperformance.Selectablelow-frequencyfiltersboostsystemresponse,protectspeakersandensurelow-endtightnessbymorepreciselymatchingtheamplifiersrangetotheloudspeakers.Barrierstrip,XLR,and1/4in.balancedinputsplusSpeakonandbindingpostoutputsprovideeasyconnections.Low-noisevariablespeedfanswithrear-to-frontairflowkeepamplifiersandrackscool.ProvenReliabilityWithover30yearsofbuildingamplifiersforthelargesttouringcompaniesandvenuesaroundtheworld,youcancountonQSCsreputationfordesigningthemostreliableampsavailable.TechnicalInfoSpecificationsContinuousPowerRating8 :500W4 :750W2 :1200W8 BridgedMono:1500W4 BridgedMono:2400WCurrentConsumption:10AmpsDistortion(Typical):20Hz-20kHz:10dBbelowratedpowerLessthan0.03%THD4and8 1.0kHzandbelow:fullratedpowerLessthan0.03%THD4and8 FrequencyResponse:20Hz-20kHz, /-1dB,-3dBpoints:5Hz-50kHzDampingFactor,1kHzandbelow:Greaterthan300at8 InputImpedance:10k unbalanced,20k balancedInputClipping:10Vrms( 22dB)Cooling:Continuouslyvariable-speedfan,rear-to-frontairflowConnectors,eachchannelInput:Activebalanced;barrierstrip,XLRand1/4in.(6.3mm)TRStipandXLRpin2positiveOutput:touch-proofbindingpostsandNeutrikSpeakonControlsFront:ACswitch,Ch.1andCh.2gainknobsRear:10-positionDIPswitchIndicatorsPowerOn:GreenLEDSignal:YellowLED,1perchannelClip:RedLED,1perchannelAmplifierProtection:Fullshortcircuit,opencircuit,thermal,ultrasonic,andRFprotectionStableintoreactiveormismatchedloadsLoadProtection:On/offmuting,ACcoupling(850,1450),triaccrowbar(2450,oneachchannel)
