Ask a Question
  • Can you stream one bluetooth or line input to multiple AMP monos simultaneously? Does it have delay?
            you can achieve the goal  through  multi room  mode, you  stream Bluetooth  or line in to the master device, and the  slave device  will get the streamer from  the master one, because the data transfer through  wireless  so  the  delay  depends on the transfer delay
