This receiver is for use with the Calumet Quad Plus 2.4GHz Wireless Trigger system.
The Quad Plus enables you to assign your flashes to four groups so that you can either isolate or combine different groups to allow for complex lighting setups. The trigger's four channels can be used so that up to four different photographers can shoot with the Quad Plus in the same location without triggering each other's flashes.
The receiver triggers flashes manually and offer flash wake-up functions on compatible flashes. They can also be used as a wireless shutter release for your camera by using an adapter cord (sold separately).
This receiver is optimized for use with Nikon Speedlights, but can also be used to trigger studio strobes or with Olympus and Sony Cameras as a wireless shutter release.
