The used Paul C. Buff CyberSync Cyber Commander controls and displays virtually every parameter of a complex studio flash setup of up to 16 light units.
This control includes the relative flashpower and modeling lamp brightness of all of the lights, from 1.56 to 6400 Ws per light. For each light connected, it provides an exact digital readout of the flash wattseconds, t.1 flash duration, color temperature, modeling watts, and the relative flashpower using the European standard numerical 0 to 10 scale (automatically adjusting as changes are made in output). Additionally, it displays the actual camera f-stop (in whole f-stops) of each light (or of all lights or of any particular group of lights) from a built-in high accuracy flashmeter that allows setting ISO and exposure time and exact calibration from your lights to your camera.
