User manual SPEEDOTRON 1005

[. . . ] Welcome to Speedotron Thank you for purchasing Speedotron Black Line equipment. The name Speedotron is synonymous with professional workmanship and the finest electronic flash equipment available. Backed by years of experience, our engineers have developed the Black Line system to take the rigors of daily professional use with consistently outstanding results. For more than 60 years, Speedotron's reputation has grown without much fanfare or advertising. [. . . ] 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. Failure to do so may cause the power supply to intermittently misfire. 9) Light Unit Outlets (4) -- sockets for connecting from one to four light units to power supply. Arranged in 3 channels with two outlets sharing 250 w/s in channel A, one 250 w/s outlet in channel B and one 500 w/s outlet in channel C. Ratio switch can combine two or all three channels 10) Power Level Control -- simultaneously controls power of all channels, in 1/4 stop increments, down to -2 stops (1/4 power). 11) Recycle Rate -- Allows normal Fast recycle or Slow recycle when limited power is available for location shooting. 12) Beeper-- Turns audible beeper on/off 6 Push the Ready/Push (4) button to verify proper system operation. When power is on, be sure Ready/Push (4) indicator is illuminated before switching Power (1) or Ratio (3) controls. The Power Level (10) control simultaneously changes the power of all three channels. When dialing power up or down, the Ready (4) light will relight and the Beeper will sound when power reaches the new desired level. Since power changes can be made very quickly with the 1005 there will be no beep if power changes are completed in less than 1/3 second, such as seen when using fast recycle rate at low power levels or dialing up/down a quarter f-stop. Rotating the Power Level (10) control will not change the brightness of the model lamps. When disassembling the system, turn Power (1) and Model (2) switches to the off position. Do not push the Ready/Push (4) switch before turning power supply off. Unplug power cord from outlet, then disconnect light units from power supply. Capacitors are automatically, internally discharged when power is dialed down or when AC power is off. 1005 Power Ratios Divide watt-seconds by 2 when using half power (-1 stop). Divide watt-seconds by 4 when using quarter power (-2 stop). 7 1005 · power supply Set three-position Ratio (3) switch for the desired power to the light unit(s). See the chart above or on the side of the power supply for ratio combinations that are possible with up to four light units.
