Mono summing?

[druu]

Hi All,

I'm currently modding a PCM1794 DAC I received last week and basically trying to give it more options as a preamp/monitor controller. It has most of what I need but ideally I'd like to implement a Mono button and a Dim button if I can.

Can anyone suggest the best way to go about this? Passive would obviously be the way to go (if it's even possible? Maybe for dimming?).

Thanks in advance!

Does anyone have a copy of NewYorkDave's mono summing schem they could send?

Would this method work ok?
