The Arri 12K Dimmer with DMX (120 V, 50-60 Hz) is an RFD Series stand alone dimmer made for Arri by LEX Products/Electrol, which combines a DX Series dimmer with a rack system to offer a 12,000 W portable dimming solution that accepts DMX 512 remote control. The unit's 8-bit resolution allows full 256-step, 0 - 100% dimming control for precision and repeatability. The panel features LED mode indicators as well as neon status indicators. Connectors include Neutrik 5 pin XLR for DMX communication and stage pin connectors for input and output. The power fail memory feature remembers dimmer level, preheat level, operating mode and the DMX 512 address. Convection cooling means absolutely quiet operation.
