Not at all. There are a total of 7 pots on the unit. One on the front case, 6 on the insides of the unit, PC board mounted.
The pot on the front case is a horizontal shift pot, or phase control. It will allow for a very accurate sync alignment of the unit to your display device. It's similar to the little "brightness" pot on the KD transcoders.
Three of the internal pots are used for precise phasing of each of the three (Y,Pr,Pb) channels, and this keeps the signals before the matrix circuit at the right gain and polarity, for correct matrix performance. Once calibrated, you should notice more accurate colors (ie. flesh tones, saturation and even the ability to discern different complexions).
Two of the internal pots are passive gain pots for red and blue color balance.
The last pot is the main gain pot.
All 7 pots will be preset by me. Only three of the pots will be covered (sealed) with a nail polish. All other pots can be adjusted by owner for preferable colors, gain, shift.
