About ARRI EB Max 2.5/4K Max High Speed Ballast with ALF and DMX, AutoScan, 50/60Hz (Stage Plug)

MAX Technology - Max Performance

Starting with the EB MAX 1.8 in 2017 ARRI built the foundation for a whole new range of high speed electronic ballasts - the EB MAX range. Together with three other models - EB MAX 2.5/4, EB MAX 6/9 and EB MAX 12/18 - the MAX range combines cutting-edge features with new remote control possibilities from 575 up to 18,000 W.

The EB MAX 2.5/4 is designed for two power classes: 2,500 W and 4,000 W. When combined with state-of-the-art ARRI daylight lampheads such as the True Blue D25 and D40 or M-Series M40, it enables optimal performance and advanced control for high image quality - at any frame rate.

The EB MAX 2.5/4 is equipped with essential features such as Active Line Filter (ALF) and Compensation of Cable Losses (CCL), delivering maximum light quality with efficient supply and wiring. The AutoScan feature ensures optimum light and image quality with a minimum of effort for high-speed recordings up to 1,000 fps and beyond.

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 range 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 2.5/4 as well as the other models of the EB MAX range offer 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.
