Does Fosi have any products with input auto sense? I have 2 large, antique radio cabinets I wat to "retrofit" but avoid having to use clunky manual remotes or a kludged method to turn it on/off.
As DNA says above. V3 mono can be switched to auto. They make a small click when they power on and it takes about 10 mins after no signal to power off. Not timed it but approx.
