Combined A+B (Symmetrical Power)
Even distribution of power, called symmetrical or combined takes the power from both A and B channels. It is the setting to use
when you want either the maximum power your pack can deliver sent to a single flash head or if you want every head plugged in
to deliver an equal amount of light. To achieve maximum power, plug a flash head into any outlet, set the Ratio/Combined switch
to A+B and both Power Output switches to full power. To achieve less then full power with a single head, change the settings of
either or both of the Power Output switches. The light output will be the sum of the two channels. If more then one head is plugged
in, every head will get equal power. The amount of power each head will get depends on how many heads are plugged in
(regardless of which outlet) and the settings of the Power Output switches. The simple calculation is as follows. Take the combined
number of both Power Output switches and divide that by the number of flash heads plugged into the pack. The result is the
amount of power each head is receiving.
Variator Control
All Dyna-Lite power packs now include the 2.0 f-stop Variator Control (sometimes referred to as the power trimmer). The Variator
Control provides maximum flexibility in ascendancy by allowing the light intensity to be adjusted in 0.2 stop increments. The Variator
adjusts the entire pack globally, meaning that as you change it, the ratios of “A” and “B” channels will not be affected. This feature is
especially useful if you are bracketing exposures. It also becomes important when you are using multiple packs and wish to fine-tune
the light balance between packs. There are many times for example where adjusting a single light an entire stop will result in too
dramatic a change. NOTE: When increasing the power with the Variator Control, the flash output is adjusted automatically.
When decreasing the power, “bleed” the pack by pushing the test fire button.
Sync/Slave/Infrared/Radio Operation
The Sync Input Socket circuitry is I.S.O approved and operated and operates on 10 volts DC to avoid damage to camera flash con-
tacts. Plug the sync cord into the PC sync terminal on the camera first, then plug the other end into the Sync Input Socket on the
power pack. On the RP series packs the Slave/Sync Switch lets you choose between slave and/or conventional sync cord operation.
Set to Sync position when using only one pack, or when this pack is used to trigger other packs. Use the Slave position when the pack
will be triggered by another flash or by an infrared transmitter. The slave-eye also responds to most infrared transmitters. The MP400,
MP800, MP1600, and SP1600 have a Pocketwizard Radio setting for use with the optional Pocketwizard transmitter.
Programming a pack (using optional Pocketwizard transmitter or transceiver)
Dyna-Lite MP/SP packs feature a built in Pocketwizard receiver. First make sure that the Sync/Slave/Radio switch is set to Radio.
Next turn on your Pocketwizard transmitter and set it to the channel you would like to use. (Note: You can program the receiver to
respond to an entire channel or a specific quad zone by selecting only that zone.) Turn on your Dyna-Lite pack and hold the test
button on your transmitter until your pack flashes. The built in receiver is now programmed and ready for use. There is a 30 second
window to “train” your pack. Turning the pack off and back on will reset the built in receiver.
