ARRI新型高速镇流器EB MAX 1.8
• DMX遥控运行模式和频率
• 覆盖575 W至1800 W四个功率等级
ARRI发布了一款高速电子镇流器的旗舰机型——EB MAX 1.8，它结合尖端特性和全新的遥控功能，针对所有575 W至1800 W的放电灯泡设计。
从2015年NAB展开始，ARRI一直在扩展旗下新型电子镇流器系列产品。所有机型都支持AutoScan（自动扫描）功能，以最简洁的操作方式保证1000 fps甚至更高帧率高速摄影的光质和画质。
当时最早发布的型号是EB 12/18 HS AutoScan，它支持12 kW和18 kW放电灯泡，灯头频率900至1200 Hz。2015年末，ARRI又用EB 6/9 HS AutoScan填补了9 kW这一功率级别的空缺。去年的NAB展，针对2.5 kW和4 kW这两个功率级别的EB 2.5/4 HS AutoScan正式亮相。到了今年的NAB展，ARRI用全新机型EB MAX 1.8组成一套完善的高速电子镇流器产品阵容。
EB MAX 1.8具备许多关键的功能特性，比如动态线缆滤波器（ALF）和电缆损耗补偿（CCL），无论从光质、光效还是接线方案都是最高水准。除了为最大程度降低噪音而提供的50或60 Hz灯泡频率，或是针对标准帧率输出的75 Hz，EB MAX 1.8还能为高速摄影提供1000 Hz频率，而且是家族中第一个支持300 Hz的型号。
高速运行模式下，EB MAX 1.8具备三种模式：AutoScan（全自动）、Man（手动频率控制）或AutoMan（结合手动频率设置和自动监测与调整）。AutoScan模式不需要过多人工干预，经过两阶段扫描灯泡频率后，镇流器会自动选择适合的频率；如有需要，所有的参数都处于连续监测与自动调整之下。
EB MAX 1.8提供了更高水平的DMX控制性能，除了开/关和调光，两种运行模式和频率现在都可以远程控制。为了最大程度方便使用，镇流器的前面板还会显示灯泡电压、DMX频道、运行模式和选择的灯泡频率。
尽管外形小巧，EB MAX 1.8却能够覆盖四个功率等级：575 W、800 W、1200 W和1800 W。结合业界顶级技术水平的ARRI日光灯头，例如True Blue D5和D12或是M系列中的M8和M18，无论任何帧率下，EB MAX 1.8都为高画质拍摄提供了最稳定的保障和先进的控制选项。

NEW ARRI HIGH-SPEED BALLAST EB MAX 1.8
• DMX remote control of operation mode and frequency
• Covers four power classes, from 575 to 1,800 W
ARRI announces a new flagship for its range of high-speed electronic ballasts. Designed for all discharge lampheads between 575 and 1,800 W, the EB MAX 1.8 combines cutting-edge features with new remote control possibilities.
Since NAB 2015 ARRI has continually expanded its latest generation of electronic ballasts. All models are equipped with an AutoScan feature that ensures optimum light and image quality with a minimum of effort for high-speed recording up to 1,000 fps and beyond.
First to be released was the EB 12/18 HS AutoScan, which allows 12 kW and 18 kW discharge lamps to be used at lamp frequencies of 900 to 1,200 Hz. Later in 2015 ARRI offered the AutoScan mode in the 9 kW class with its EB 6/9 HS AutoScan ballast. At NAB last year the EB 2.5/4 HS AutoScan was announced, designed for the 2.5 kW and 4 kW power classes, and now at NAB 2017 ARRI completes the range by unveiling the all-new EB MAX 1.8.
The EB MAX 1.8 includes essential features such as Active Line Filter (ALF) and Compensation for Cable Losses (CCL), delivering maximum light quality with efficient supply and wiring. Besides lamp operation at 50 or 60 Hz if noise needs to be minimized, or at 75 Hz for standard frame rates, the EB MAX 1.8 accommodates high-speed frequencies at 1,000 Hz and – for the first time – at 300 Hz.
Three different modes are available for high-speed operation: AutoScan (fully automatic), Man (manual frequency control) or AutoMan (combining manual frequency setting with automatic frequency control). Using the AutoScan mode requires no further interaction by an operator. After a two-stage scan the lamp frequency is selected and set by the ballast; all parameters are continuously monitored and adjusted automatically, if required.
The EB MAX 1.8 offers new levels of DMX control. In addition to on/off and dimming, both operation mode and frequency can now be controlled remotely. For ultimate ease of use, indicators on the ballast’s front panel display the lamp wattage, DMX channel, operation mode and selected lamp frequency.
Despite its compact housing, the EB MAX 1.8 covers four different power classes: 575 W, 800 W, 1,200 W, and 1,800 W. When combined with state-of-the-art ARRI daylight lampheads such as the True Blue D5 and D12, or M-Series M8 and M18, it enables optimal performance and advanced controls for high image quality – at any frame rate.
