LINK is a 4-universe controller designed to control compatible DMX devices with control from the dedicated Airstream DMX LINK iOS App for iPad. LINK can connect to an IPad wirelessly or hardwired. When connected wirelessly, LINK creates a private standalone 2.4 or 5 GHz DSSS (Direct Sequence Spread Spectrum) WiFi network between an iPad and LINK console, which can coexist in busy RF environments alongside other wireless technologies. Connecting wirelessly will also allow you to undock the iPad and remotely control, program and playback your light show. If you prefer to use a hardwired connection between the IPad and LINK you will need a USB cable adapter, not included, which will also allow the IPad to charge at the same time. Four (4) hardwired, 5-pin XLR outputs on the rear of LINK send constant and reliable DMX signal to compatible DMX devices.
