CHAUVET DJ CHAUVET 2x DJ DMX-4 Dimmer/Relay Pack for LED Fixtures With 5' Female DMX Cable

It's a 4-channel dimmer/relay pack providing DMX control for on/off or dimming to units not equipped with DMX on their own. The fixture is optimized for use with small LED fixtures to prevent ghosting and flickering. Each of the 4 sets of outlets (duplex) can be set to any DMX address and independently set as a dimmer or relay. Sixteen user-selectable chase patterns make programming a breeze.
