25年历史的美国ART在业内享有盛名 物美价廉的产品深受使用的喜爱。此话放为原版正宗ART！性能品质优越！购买前请仔细看好认清真伪！！！官方网站如下：http://www.artproaudio.com/products.asp?type=79&cat=1&id=146曾经被模仿。从未被超越！！！ART MPA GOLD 被山寨之后 ART又做升级 最新顶级版本的双通道高话放Pro MPA II同时也启用新版的商标LOGO。新款的ART ProMPA II作为老版MPA GOLD的升级版本也是标致着ART话放系列的顶级产品。是一款采用高性表现的话筒前置放大技术的前置放大。每个话筒输入电路带有可切换的48V幻象电源和可变的输入阻抗功能，这功能能提高任何高质量动圈话筒和铝带式话筒的性能表现 。ProMPA II 能设置成两个单声道或立体声（中/侧边），单声道为将两个话筒信号混合后输出，立体声将两个话筒信号以左/右信号输出。ProMPA II的一对12AX7 电子管能在低极板电压或高极板电压下工作，这使得前置放大的音色更好和具有更高的性能表现。大的VU输出电平表业示输出电平，同时LED阵列电平表显示电子管增益。装于一个标准2U的机架式全钢机箱中，前面板为铝制面板。ProMPA II 是为录音室、唱片制室或现场扩声长期稳定使用操作。特性：可变输入阻抗用于灵活话筒音色调整(150 欧姆到2400欧姆)选择极板电压大VU电平表分立的A类输入话筒前置放大器C低增益设置时非常低的噪声非常低的总谐波失真(THD)很宽的频率响应装于前面板的乐器输入插座支持中间位置/侧旁话筒技术 支持MS制式录音模式在 +4dbm/-10dbv输出操作选择立体声/输出控制独立操作s自动乐器输入选择详述频率响应15Hz to 48 kHz (+0, -1dB) @正常电压15Hz to 120 kHz (+0, -1dB) @高电压动态范围: >110dB ("A"计权)共模抑制比: >90dB总谐波失真: <0.005% (标准)等值输入噪声-129dBu (XLR, "A"计权)最大输入电平: +19dBu (cannon)最大乐器输入: +17dBu输入阻抗: 150-3000欧姆调整 (XLR)>800K 欧姆 (乐器)最大输出电平: +27dBu (XLR)输出阻抗: < 47 欧姆(XLR)最大增益: 75dB电平表刻度: 0 VU = +4dBu output (+4dB模式) 0 VU = -10dBV输出 (-10dB 模式)高通滤波器: single pole, 10-200 Hz adjustable电源需求: 125 VAC / 220VAC 出口产品按出国家配置体积: (高x宽x深 英寸) 3.50 x 19.0 x 8.75体积: (高x宽x深 厘米) 88 x 482x 222重量: (磅/公斤) 10.5 / 4.7请单击高清大图观看：The new ARTProMPA IIis the next generation in affordable high performance microphone preamp technology. Each microphone input circuit, with selectable 48v phantom power, features variable input impedance which can radically vary the overall performance of any high quality dynamic or ribbon microphone. TheProMPA IIcan be configured for dual mono or stereo operation with selectable mid/side mic support, summing the adjacent channel, to decode left/right signals.TheProMPA IIcan operate at either a low or high plate voltage on the two integrated hand-selected 12AX7 tubes for wider variation of preamp tone and performance. Large back-lit analog VU output meters display output levels while multi-colored LED arrays show tube gain.Housed in a standard 2u space rack-mountable steel chassis, with CNC routed black anodized aluminum face panel, theProMPA IIis designed to deliver years of reliable operation in the studio, production facility, or on the road for live sound reinforcement.FeaturesVariable Input Impedance For Flexible Microphone Voicing (150 Ohms To 2400 Ohms)Selectable Plate VoltageLarge VU MetersBacklit Function SwitchesDiscrete Class-A Input Microphone PreamplifierLow Noise at Lower Gain SettingsExtremely Low Total Harmonic Distortion (THD)Wide Frequency ResponseAdditional Front Mounted Instrument Input JackSupports Mid/Side Miking TechniqueOperates at +4dbm/-10dbv OutputSelectable Stereo/Dual Operation of Output ControlsAutomatic Instrument Input SelectionSpecificationsFrequency Response15Hz to 48 kHz (+0, -1dB) @ normal plate voltage15Hz to 120 kHz (+0, -1dB) @ high plate voltageDynamic range:>110dB ("A" weighted)CMRR:>90dBTHD:<0.005% (typical)Equivalent Input Noise:-129dBu (XLR, "A" weighted)Maximum Input Level:+19dBu (cannon)Maximum Instrument Input:+17dBuInput Impedance:150-3000 Ohms adjustable (XLR)>800K Ohms (Instrument)Maximum Output Level:+27dBu (XLR)Output Impedance::< 47 Ohms (XLR)Maximum Gain:75dBMeter Calibration:0 VU = +4dBu output (+4dB mode)0 VU = -10dBV output (-10dB mode)High Pass Filter:single pole, 10-200 Hz adjustablePower Requirements:125 VAC / 220VCA Export units configured for country of destinationDimensions: (HxWxD in)3.50 x 19.0 x 8.75Dimensions: (HxWxD mm)88 x 482x 222Weight: (lb/kg)10.5 / 4.7
