The Dot Line Corporation's RS-RT03R4C/HS Wireless 4-Channel Hot Shoe Receiver allows multiple flashes to be triggered by the same signal from a RPS 4-Channel Wireless Flash Trigger (RS-RT03K4C/HS). It allows the user to mount a standard speedlite using the hot shoe on the receiver. Its built-in PC outlet accepts flash units that do not have a hot shoe. The receiver can mount to your flash unit on a tripod or light stand with a 1/4"-20 threaded mount, or onto an accessory shoe. The receiver's versatile design features a holder for standard umbrellas, and it has a tilt feature so you can "bounce" your flash/umbrella combination.
