The Obey 40 is the next step up from the Obey 10, allowing for control of up to 12 fixtures at 16 channels each. With a slightly larger size comes a larger capacity: the Obey 40 has 30 banks on 8 scenes, or up to 240 scenes. The Obey 40 offers the flexibility of its little brother but also adds fog and strobe control and MIDI compatibility.
