I am trying to fire an older Speedotron 4803CX pack using a Profoto Air Sync remote. I am using a short 3.5mm to household cable connected to the out terminal on the Air Sync. Pressing the test button results in nothing happening. I tried a second Air sync remote and, again, nothing happens.
I connected a Pocketwizard to the same cable and it fires the Speedotron pack. So I know the cable and the Speedotron sync terminal works.
I connected the Profoto Air Sync to a White Lightning mono light and it fired the WL unit. So I know the Profoto Air Sync unit works.
So, the problem seems to be some kind of compatibility between Profoto and Speedotron. The only thing I can think of is maybe I need a low voltage adapter? From what I understand, the Speedotron has a high voltage sync. Maybe the Profoto doesn't put out enough juice to fire it but the PW does?
Any other ideas?
For inquiring minds, the only reason I am bothering with all this is because I acquired a 4800ws Desisti Speedotron fresnel and would like to integrate this unique light into my Profoto system.
