A handy wireless receiver which is to be used with our wireless-tr set. This unit can be added to the wireless-tr if multiple DMX lines are required. Each receiver is supplied with a power supply. The receiver is in the form of a female XLR plug. To set the working frequency simply use the small switch on the side of the unit to set the same colour LED as the transmitter, this should be done before connection is made between the DMX controller and transmitter and DMX light to receiver. A great way to cut down on time consuming cable runs.
