The NSI / Leviton MC-7024 Light Console is so easy to program and operate, the instructions are silk-screened on the back of the unit. Your 24-channel NSI MC 7024 console provides three operating modes: standard 2-scene preset operation, single scene wide mode for double channel capacity, and memory scene operation mode. The NSI MC-7024 is a control board only. Dimmer pack(s) required — CCI Solutions recommends a dimmer pack such as the Leviton NSI-D4DMX-MD3.
