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.
