Customizing the amp for 3rd party use.

I love the way the amp and looks. I think this is a great amp for home uses. I need it for 3rd party uses in vacation homes where guest can access it and not actually touch it. I needed it for 2 zones to play the same source and stay set to Bluetooth even if the power goes out comes back on. A physical switch would be great to lock it in to Bluetooth only mode. Also, it someone is connected to it and leaves the area, it will release their device and allow it for others to find it and connect to it.

I have not installed it yet at the place where it will be used, but I plan on using a IR/RF remote system to reset the amp back to Bluetooth incase it resets. This is an added cost, but it is the only way I know to work around this issue, providing the amp allows a 3 party IR system to control it.

Overall, for home use, I think this is a great amp and the remote that comes with it is a nice feature.
