Photo Forum / General Photo Topics / General Topics / November 2004hardwire PC sync cords together?
I want to be able to fire four flash heads at once, without using the slaves, since these would be constantly set off by amateur camera flashes in the room at an event. The sync. terminals are just 1/4" guitar plugs, so can I just get some guitar leads, and plug them all into a home made box that joins them all together in parallel, and just use the PC cord that came with the flashes to connect to the camera? The sync' voltage of the heads is supposedly 8v, so does this mean I'm subjecting my camera to 32v? Would you recommend some voltage protection for that with a digital SLR? Oh, wouldn't voltages in parallel stay the same? Serial connection would add them together. > I want to be able to fire four flash heads at once, without using the > slaves, since these would be constantly set off by amateur camera flashes in [quoted text clipped - 4 lines] > supposedly 8v, so does this mean I'm subjecting my camera to 32v?

They make a 3-1 plug that you can plug 3 separate sync cords into and then one cord out goes to the camera so 3 flashes can be fired hard wire >I want to be able to fire four flash heads at once, without using the > slaves, since these would be constantly set off by amateur camera flashes [quoted text clipped - 8 lines] > you > recommend some voltage protection for that with a digital SLR? > I want to be able to fire four flash heads at once, without using the > slaves, since these would be constantly set off by amateur camera flashes in [quoted text clipped - 4 lines] > supposedly 8v, so does this mean I'm subjecting my camera to 32v?

You might get away with what you suggest and you might not or it might work for a while and it might not. To do what you suggest all of the flashes would have to have the same polarity and the same trigger voltage. Do not attempt this unless you can measure the voltage and the polarity. Film, the only relevant medium! me |
