For the C-DSP this feature is not so important because the A/D and D/A converters are really good, so that there is no big difference between the optical and analog input but for the P-DSP this feature is more noticeable.
Regarding the connection you are right, the switch switches between ground and +3,3V because we need defined values at the controllers input. Just do nothing might cause an undefined state which is not so good. ..."
As I received this message already after my remote controller was made and installed on 4 wire cable I could not really test this (switch) feature.
The only thing I noticed in comparision to informations found on forum is that I DIDN'T notice any wierd/strange/dangerous noises when I was switching the input sources with my laptop when my system was ON with the amps connected and running.
Kick appears when I turn on the DVD (Alpine DHA-S680) - appears SPDIF and volume control is turn on. The louder the sound, the more kick.
