My amp is coming around nicely. It makes music already and Eval1 is switching on and off nicely with mains on smps1200.
I have a question on smps standby:
I have added an 12V input and output in parallel (see picture). I plan to connect the 12V adapter of my streamer to the input. 12V output will go to said streamer.
The smps standby only needs a little power. So I think the streamer adapter is able to power both. This way I circumvent the use of an extra adapter.
The 12V plus I plan to connect to a switch on the face plate and then to J5.1 (smps standby). When the switch is connected position the smps1200 will switch off.
Technically it works fine. Smps turns off with 12V on J5.1 (smps standby) and turns on again 12V is disconnected. I have not tested with music on.
What to do with 12V GND wire? I have connect it to GND of the smps1200 but does it need to be connected to the amp at all? I'm a bit afraid of humming when connecting amp GND with 12V adapter GND.
