can someone explain this to me please......
if you have a blue 473nm connected to pins 7 and 20 and a blue 457nm connected to pins 8 and 21, how does the system know what analogue signal to use if you are making magenta by mixing blue and red ? in other words which blue diode to use ?
i don't have a 457nm blue but would like to understand this ?
thanks .........dave321
