RadioPopper Px Studio Set Welcome to the world’s best wireless flash system, The Px System from RadioPopper. The RadioPopper PX system allows you to use the automatic and high-speed sync functions built into your existing flash units without concern of whether or not the master and slave units can “see” each other. PX Transmitter At the core of this system is the PX Transmitter. You now have the ability to place your lights wherever you choose. Control the output power of each slave flash from the camera body manually or automatically via your camera’s ETTL or iTTL logic system. It’s also the world’s first product to effectively provide you High Speed Sync by radio. Take advantage of eTTL/iTTL and High Speed Sync, all while avoiding the drawbacks of line of sight, short range and sun-light interference. The PX Transmitter controls your remote flashes that have a PX Receiver attached. One Transmitter allows you to control as many flashes as you want. The Px Transmitter can control power levels on JrX and Jr2 Receivers as well. It can also trigger the Nano Receiver. PX Receiver The RadioPopper PX Receiver works best when paired with the Px Transmitter. There are quite a few options for speedlights that work with Px Receiver. These brands include Nikon, Canon, Nissin and Quantum lights. With a bracket supplied during purchase, just line up the correct slot and insert the Receiver. Once you have set the correct hardware version through the Receiver’s interface, you’re almost ready to go. The PX Receiver works with all sixteen channels provided by RadioPopper units. The Px Receiver has a great feature that allows your unit to scan all sixteen channels and populate the channel with the least amount of interference with the Px Transmitter. Once the channel has populated, set the Px Transmitter to the corresponding channel and you are ready to go. The Px units have a feedback option for trouble shooting. The Px Receiver works with all RadioPopper Transmitters and even can be triggered by the Sekonic Module. High Speed Sync and iTTL/ETTL are some of great things that the Px Receiver can do.
