General Instructions for all power packs
The following instructions are applicable to all Dyna-Lite power packs except as noted. Additional features
specific to individual packs are described on the pages that follow.
Flash Heads
To plug in flash heads, first plug the flash head extension cable into flash head pigtail, then plug the other end into a
Flash Head Outlet (
this can be done at anytime without shutting down the power pack since outlets are arc protected
). Align the
white dot on the extension cable plug with the back of the pack.
AC Power
First plug the AC power cord into the power pack, then into a grounded AC outlet. Next, turn AC Power Switch on. Then, wait for
the ready light or audible beep before firing flash. The Ready Light Switch also serves as an open flash test switch and signals
100% flash readiness. NOTE: The Audible Ready Indicator indicates 100% flash readiness and can be turned on or off.
Modeling Lamps
Turn Modeling Light Switch on. Make sure modeling light switch on back of flash head is turned on. All power packs have
individually operated modeling light switches that can be used to control the brightness on the modeling lamp to match the
relative intensity of the flash.
Flash Head Power
Power Control Switches can be adjusted to provide full, half or quarter power to the flash head outlets in the
respective “A” or “B” channels.
Ratio/Combined Switch
All Dyna-Lite power packs feature the Ratio/ Combined switch. On all packs the flash head outlets are grouped into two separate
channels (sometimes called banks) marked “A” and “B”. The switch has two options; the first is A:B and the second is A+B.
Ratio A:B (Asymmetrical Power)
Uneven distribution of power to the A and B channels is referred to as asymmetrical or ratio and allows more control of light out-
put by dividing the pack into two halves or channels that can each be separately controlled over a three stop range. First make
sure that you have the Ratio/Combined switch set to A:B. Now the corresponding Power Control switches control each channel
individually. If you plug one head into the Channel A side, that Power Control regulates only that same side. The Channel B side is
dormant until you plug a head into an outlet on the “B” side. Consequently, the Power Control switch on the B side only controls
Channel B. As you plug in an additional head to either (or both) sides, the power is equally split, but only among each channel. If
you had one flash head in Channel A set at 100 watt/seconds and two heads in Channel B set at 100 watt/seconds, the A head
would deliver 100 watt/seconds of power and each of the B heads would deliver 50 watt/second each.
