Power pack with 3 lamp outlets, controlled over 3 individual channels (like 3 power packs in one). 1600 J flash energy. Individual (asymmetrical) output distribution. Maximum control range: over 9 f-stop intervals or over full 10 f-stop levels in whole or 1/10 f-stop intervals. Very high repetitive precision. Automatic stabilisation of the colour temperature ECTC (Enhanced Colour Temperature Control) over the whole control range and up to 6 f-stops in asymmetrical mode. Internal discharge when the power is reduced. Photocell, infrared and RFS receiver for flash triggering (all can be switched off separately). Front panel with modern, dimmable, LCD menu system, with illuminated silicone keyboard resistant to scratches and LED displays. Selectable flash duration. Modelling light with 8 different proportionality levels, adjustable to all broncolor power packs and monolights. By default, integrated radio receiver. Visual and audible flash monitoring by dim function of the modelling light during charging as well as different buzzers. Bright large ready display and buzzer (can be switched off). Can be switched to fast charging mode. Fan cooling for long flash sequences and thermal protection. 8 memory functions (the entered data are retained should the unit be switched off or in case of a power cut). Robust aluminium housing, side walls with hard rubber components. Automatic adaptation to the respective mains voltage.
