The name Speedotron is synonymous with professional workmanship and the finest electronic flash equipment available.

[. . . ] Each power supply is divided into three channels with different levels of power, except for the 405 (which has two). These channels may may be joined for even (symmetrical) output to all outlets or separated for unequal (asymmetrical) output to a set of outlets in one or more channels. Power distribution charts are provided in the next section of this manual and on the side of each power supply. When we refer to ratioing, we are describing the levels of power output from the power supply to the light units only. These power output ratios do not mean that the light falling on the subject will be at that same ratio. This will only occur if the light units are the same and have the same flash tube, reflector, cable length, light control accessories, are at the same distance to the subject, and there is no overlap of lighting on the subject, etc. Power output ratios are only offered as a guide to help you determine your lighting arrangements. *Not available on 405 power supplies. 5 instructions and information General Instructions and Information Speedotron power supplies.
