The original Apathy controlled all 512 DMX levels with its single control knob. However this was too simplistic for some users so Doug Fleenor Design added the industry’s most hostile user interface to create the Apathy Minus. Now, through a complex timed sequence of button presses, any single DMX channel can be assigned to the knob. Once selected, channels may be easily incremented or decremented.
Note: Some older DMX receivers will be unstable when receiving a 2Hz DMX512 signal. If this is the case remove the microprocessor in U1, bend pin 4 out, and reinsert processor into socket. Power save mode will be defeated however battery life will be severely shortened.
