I posted the following on amazon.com;
"How will the latency adjustment (microphone on the unit) perform when having a multiroom setup with 7 wiim pros connected to two receivers in a rack?"I then recieved the reply from WiiM below;
"The latency measurement is performed to measure the connected audio devices of the specific Pro. You can measure the 7 devices one by one. I don't quite understand how you connect 7 WiiM Pros to two receivers. Can you please send us a feedback from the App and let us know the exact system setup so we can provide more appropriate solution for you?"
To answer the question and hopefully get a response from @WiiM Team ;
I will make use of two Dayton Audio MA1260 receivers that each supports 6 separate zones. Both receivers will be located in the same storage room. From there I have speaker cables connected to speakers throughout my house.
My plan is then to connect one wiim pro to each zone (starting with 7 WiiM pros to 7 different zones). I hope I should be able to cast to my kitchen, office, bedroom or any other wiim connected zone using Google Home (Chromecast Audio) via e.g. Google Nest minis or Google nest hubs.
My concern in regards to latency measurements is that the wiim pros will all be in the same room (storage room) and won't be able to pick up the output sound since that will be in another room, for example kitchens or bathroom.
Does that answer your question? And perhaps more importantly, is my plan even doable or am I making things more complex than needed?
