You can control flash sync, remote control, Auto TTL, and HSS using the wireless connection provided by the Profoto Connect Wireless Transmitter for Canon cameras. In Air lights, the remote control and flash sync are also controlled by the transmitter. The Connect transmitter itself has three settings. Auto, the first option, eliminates any guesswork involved in setting up your flashes. If you want to set the flashes yourself and be more creative, you can use the manual setting. Naturally, the final setting is to disable it when the transmitter is not in use.
