The PocketWizard PowerST4 Receiver for Elinchrom RX enables remote power control of Elinchrom RX flashes using PocketWizard ControlTL technology. With a MiniTT1 Transmitter or FlexTT5 Transceiver on your camera and a PowerST4 plugged into your Elinchrom RX flash, you can now adjust the flash power settings directly from the camera. Add the AC3 ZoneController and you can control three different zones of lights in 1/3-stop increments with up to a six-stop range. Utilize PocketWizard's unique features such as HyperSync and OptimizedRear Curtain Sync for maximum control of your lighting.

ControlTL: PocketWizard's new firmware platform taps into the full potential of your camera and flash system enabling an entirely new level of remote flash capability through our proven radio communications. ControlTL firmware is configurable and upgradeable for "future-proof" continuous improvement.
Manual Power Control: When the PowerST4 is paired with either the MiniTT1 or FlexTT5 (both optional) on camera, you can adjust the power settings of your Elinchrom RX lights from the camera's position either with the Flash Exposure Compensation dial or add the (optional) AC3 ZoneController for three zones of power control.
ZoneControl: Use either the AC3 ZoneController or a MultiMAX radio (both optional) to control up to three zones of light with as many lights in each zone as you want. Use the A-B-C zone switch on the PowerST4 to assign the zone.
PowerTracking: Any change in ISO or aperture is automatically compensated for in your flash power settings. Set your (optional) AC3 ZoneController to manual and PowerTracking is turned off for absolute manual control.
Channels/Learn Mode: The PowerST4 can be programmed as needed with up to 20 ControlTL channels for Manual Power Control, or 32 standard channels for simple triggering. Channels can be configured with the PocketWizard Utility (free downloadable software), the Learn function from another PocketWizard radio, or the reset function to configure back to factory settings.
Reverse Compatible: The PowerST4 Receiver operates on the same channels as all other PocketWizard radios and will work with any PocketWizard radio you may already have.
Low-Profile Design: The PowerST4 is tiny and simply plugs into the remote socket on an Elinchrom RX flash. Note: Ranger RX requires EL-19374 EL Skyport Transceiver RX Adapter.
No Batteries Required: The PowerST4 gets its power from the flash.
HyperSync: HyperSync allows photographers to achieve faster X-sync speeds, all the way up to 1/8000 second, will full power flash. Now you can cut the ambient light and use wide-open apertures, outdoors in bright sunlight. That extra speed can also freeze action, whether shooting models or athletes in motion. HyperSync works with both TTL speedlites and full size studio flash. All you need is a MiniTT1 or FlexTT5 (both optional) on-camera that has been tuned to your specific camera via the PocketWizard Utility. (camera and flash model dependent)
Programmable and Upgradeable: Use the PocketWizard Utility with the PowerST4's USB port to program the receiver to any PocketWizard channel and zone. You can also program your initial power settings, modeling light settings and beeper settings using the Utility. The PowerST4 can be easily upgraded whenever updates and feature enhancements are available.
