DCC on DCS variable channel?

I mean no offense but I don't understand what you're trying to do. Why use a variable channel? With DCC you have voltage on the rails just like TMCC or DCS. You won't need the vary the input voltage to the base station. You still won't be able to have DCC in the same electrical block as TMCC/DCS. 

No offense taken. I'm working this through and have more poorly thought out purchases, than I can count. Having thought more, I guess I'm hoping I can use a Z1000 or Z500 as the power supply, for a DCC base station. There is no need to include DCS, at all. I'm just used to wiring the loop I use for LionChief locos, through DCS as a means of being able to shut the whole system down, at once. 

Okay. I understand. I see no reason why you can't use a Z1000 or a Z500 to power a DCC base station with the exception that you will be limited on the amount of amperage you get out of it. My NCE DCC system accepts any AC power source. I used to use a PW ZW but last year I bought the 10 Amp NCE power supply that is designed for O scale.
