Hi there,
I'm new to this forum and new to programming microcontrollers in general. I have a question for a little project I'd like to attempt, but have zero experience with whatsoever. I have a preamp that outputs a signal on SPDIF and XLR/RCA at the same time. The XLR signal goes to my two monoblocks (amps) which drive my speakers. My amps have 12V trigger in to switch them on/off depending on the signal but my preamp does not have a trigger out. I was thinking to connect a teensy board to the spdif out of my preamp and on ANY signal it sends a signal over 12V to both my amps to switch them on. If no sound is being played for 60s or whatnot the 12V signal is cut off again and my amps will switch off. Is this doable with teensy and where would I begin (as in, next to the teensy board it self, what components should I get?). Thanks in advance and open to any suggestions!
edit: Initially I thought I would have to trigger both amps at the same time, but this is actually not needed as the amps have 12V in/out, so one amp can trigger the other.
edit2: On some other forums you read that amps can sometimes already be trigger at a 5V signal, I could check this with the maker of my amplifier as this might reduce the components required?
