Adjusting the Sync Interval
Before we describe how to adjust the Sync Interval, some background explanation is in order. If you’re the non-
technical type, skip ahead to the next page. This sounds pretty complicated and scary, but it’s not really - nothing to be
afraid of. In most cases you’ll make this adjustment once (if at all) then forget about it.
In order for the slave flash to respond correctly to the “reproduced” light signal from the P1 Receiver, the timing of
the reproduced signal must be exceptionally accurate. To insure the original signal and the reproduced signal match
perfectly, both the P1 Transmitter and the P1 Receiver must operate on the same timing clock, and these two clocks
must remain in sync with each other to about a millionth of a second.
To accomplish this, the P1 Transmitter sends out a carrier signal at a particular timing and the receivers use this signal
to maintain their timing clocks synchronized to that of the transmitter.
It is important that the timing of this “clock” signal be adjusted so that it does not conflict with the timing of the light
pulses emitted by your Master Flash or IR Commander. There’s a lot of math and a thirty minute discussion behind this
so we’ll spare you the details. Suffice to say your P1 system may require a quick and painless adjustment to this timing
during first use, or if you make any major changes to your gear.
The timing of the light pulses created by your Master Flash or IR Commander are determined by a combination of what
type of camera body you’re using along with what device you’re using as your Master Flash or IR Commander on the
hot shoe. Because this can vary somewhat depending on your particular hardware setup, you have the ability to adjust
this timing interval to iron out any conflict that may exist.
How do I know if the Sync Interval needs adjusting?
The sync interval may be adjusted to a setting of 1 to 10. Your P1 Transmitter ships on setting “10” which works well for
most hardware. If your slave flash is being activated correctly by radio, you likely will not need to adjust this setting.
Indicating an adjustment is required - you will see your slave flash emit a brief burst of light, but no flash will be visible
in your actual exposure. What you are seeing is your slave flash emitting a pre-flash but no main flash. If you observe
this behavior in a majority of your shots - adjusting the Sync Interval will likely solve the problem.
You may need to re-adjust this interval if you go to a different class of camera body, a different brand, or if you begin
shooting lots of flash groups (you’re using A, B, and C flash groups for example).
With any given mix of camera body and slave flash hardware, there will likely be several Sync Interval settings that will
not work and several that will. In any case, you should be able to find at least one setting that works reliably for your
hardware.
