First, load the gel string as described above. Then, slowly increase control protocol level until the gel string reaches it's tail, or until maximum control level is attained. Then slowly increase control protocol level. Continue these adjustments until the last colour frame is positioned properly at maximum control protocol level settings. If maximum level is reached before the last gel string frame, repeat above procedure, but rotate the trim pot clockwise until the final frame is parked in the appropriate position.
All outputs are independent of one another, and each line has it's own return.
The purpose of the return socket is to maintain a constant voltage level across all units on each line, and to prevent line loss. Set the voltage selection switch to the desired setting and refit the cover and endplate using the 2 screws. All Chroma-Qs show no power indicator. 24VDC power supply is not providing power to Chroma-Q. Check if mains power is on and red 24VDC LED is on. Single Chroma-Q power indicator is off.
