Impact PowerTrigger 16 Channel AC Transmitter and Receiver Set

The PowerTrigger 16 Channel AC Transmitter and Receiver Set from Impact contains everything you'll need to wirelessly trigger your studio AC flash units at distances up to 75'. The set includes a 16 channel transmitter and receiver as well as a 2.5mm sub-mini to PC cable, a 3.5mm to 1/4" monoplug adapter and a pre-installed battery for the transmitter.

The low-profile 1.2 x 1.6 x 2.8" PowerTrigger transmitter has a hot shoe for your camera, a test button, and 16 separate channels operating on the 433 MHz frequency to prevent interference from other devices. Channels are chosen on both the transmitter and receiver by configuring 4 DIP switches in 1 of 16 permutations on both the transmitter or receiver for wireless triggering from up to 75' away with flash sync speeds of up to 1/200 second. The transmitter runs on a pre-installed, 23A battery that can last up to 2 years with normal use.

Unlike the transmitter, the PowerTrigger receiver doesn't use batteries and is instead powered by the same AC cord that's used for your monolight. Think of it as an in-line receiver. Simply plug the end of the power cord into the receiver then plug the receiver's power cord into the head's power outlet. Finally, plug the PowerTrigger's attached 3.5mm sync cable into the flash. A 1/4" mono plug adapter is provided if the head doesn't have 3.5mm input. If you don't know what your flash head's sync voltage is, or if you're using an older unit you might want to purchase a Wein Safe-Sync adapter (MFR# 990-510) to insure that the sync voltage remains under 6V. The Safe Sync's monoplug attachment can be easily adapted to 3.5mm if necessary.
