S300 12v Trigger

Hi, I am looking to buy a S300 for my living room setup. The preamp that it will be used with doesn’t have a trigger output, which got me wondering, what is the lowest voltage that can trigger the relay?

Would 5V be enough? This would enable me to trigger the amp from the switched USB output from the TV…just a thought. I could build or buy something I am sure, but that would be a super simple solution :slight_smile:


Anything between 5v - 12v should be OK. However, 12v is the expected. So if 5v doesn’t work, that’s why.
