Turning Fosi Power Amp on/off. It works 😃

[kjell.bjornfors]

Today Iḿ using a Yamaha AVR as power amp for my Ultra and switching the amp on/off with Home Assistant and a wall socket. It works very good, but the amp use a lot of energy and have seven useless power stages. There is also a communication delay, so the sub is already on when the Yamaha goes on.
Iḿ thinking of buying a Fosi Audio ZA3 because it has an trigger input. Does the on/off function in Fosi ZA3 work with Wiim Ultra?
Or should I buy 2 of them, or anything else that works with Ultra. I want to use the trigger function and I understand there is a current limitation in Ultra HW.

Are you concerned the 12v trigger output of the Ultra might not power the 12v trigger relays in 2 Fosi amps?

I haven't heard of any such limit and I'd be shocked that WiiM engineers didn't consider this situation.
I believe there are many here with this exact configuration.

I’m using the Ultra’s trigger out to 2 Fosi ZA3 and an SVS sub. All 3 power on/off without issue.

Yes it does. I use it

I bought 2 Fosi ZA3 and it works very well together with Wiim Ultra
