The RadioPopper RPCube (Nikon) is a component that makes your JrX Studio receiver that much greater! In addition to give flash power control, it also provides you with a standard sync port. No need to scour the internet for a expensive, hard-to-find adapter to give your old flash a sync port. Installation is easy. Simply slide your flash onto the hotshoe of the RPCube and lock it into place. Then, using a 3.5mm cable (provided with JrX receiver) plug one end into the RPCube a nd the other into the appropriate port on your JrX studio receiver. Make sure your flash is then set to TTL.
The RPCube enables the EZset Strobe functionality of the JrX Studio Receiver giving you remote power output control of almost any hand held dedicated TTL flash that is Nikon Compatible. Using the dials on the JrX Transmitter and/or the digital groups on the PX Transmitter you can adjust your lights up and down right from your camera.
