The Impact R616AC 16 Channel Radio Slave System is designed to trigger strobes wirelessly. This system works in tandem with most AC powered strobe packs or monolights, and draws power via the attached AC cord. There are no batteries in the receiver to worry about during a busy photo shoot.
Sixteen channels offer more than ample capacity to avoid local radio interference, and total freedom from dragging around a sync cord. Sixteen channels also provide the opportunity to assign different groupings of lights to their own channel, which can be selected by switching to their respective channel on the transmitter that mounts on the camera's hot shoe.
The transmitter is powered by an included 23A, 12V alkaline battery. The battery has a lifespan of ~10,000 flashes, as the transmitter only draws power from it when it is firing.
Note: This set comes with adapters for mini and monoplug sync connections.
