The Linx-Tx8 is an 8 button transmitter that when used with the Linx-Rx form an eight channel short range wireless link. The 1/4 J6 output from the Linx-Rx can be used directly to run small relays and solenoids, or fed into any of Gilderfluke's relay modules to control higher current/voltage loads. Most commonly, the output of the Linx-Rx is used to start a sound or show playing on a Gilderfluke audio repeater or show controller.
