I have the RP-150M powered bookshelf speakers and have it connected to a turntable. I use the remote to turn it on and off, but it is supposed to have auto standby which wakes it when it detects a signal. It turns off by itself after a certain amount of time of not receiving a signal, however, it does not wake by itself. I have to manually use the remote. Is this a known issue and is there a fix to it? I've tried to wake it using Bluetooth as well.. Thanks!
