Connecting to a TTL flash is simple as the receiver has a hot shoe on the top for communication. For strobes and manual flashes, the Air R also has a PC sync terminal for basic connections. Mounting the receiver is simple as well with a cold foot on the bottom with a 1/4"-20 thread for stands. There is also a flip-out stand for placing directly on a flat surface. Additionally, it runs on 2 AAA batteries. This radio receiver features the newer Sony Multi Interface Shoe and is not directly compatible with the older flashes featuring the Sony/Minolta-style Auto-lock Accessory Shoe without the use of an optional adapter.
