Check the listing for details. Chauvet DJ DMX-4 4-channel DMX Dimmer/Switch Pack (2-pack) Bundle. Condition: New. Listed at 379.98 USD. If you need control over dimmable lighting fixtures that aren't equipped with DMX, then you're in luck. The Chauvet DJ DMX-4 dimmer/relay pack gives you four channels of dimming or switching, with up to five amps per channel (15A max). Unlike some dimmer/switch packs the DMX-4 will provide a phantom load that prevents ghosting and flickering in LED fixtures, adding flexibility to your rig while ensuring your light show will look great. And 16 built-in configurable chases make it easy to get a light show up and running really fast. Four duplex outlets allow you to control up to eight fixtures, and you can assign a separate DMX address to each duplex. When you need control over lighting instruments that aren't equipped with DMX, Sweetwater can confidently recommend the Chauvet DMX-4 dimmer/relay pack.
