Yamaha CS80

Hi allI found some differences in the calibration process between the CS60 and the 80; while in the first the service manual tells to place the cutoff sliders at half course both for HPF and LPF, I can find more detailed infos about the second one, that is to exactly set the HPF at 4.0V and the LPF at 3.3V; can anybody explain why is there a difference between the default voltage set for the HPF compared to that of the LPF??Thanks for your replies..M
