ZP100 humming when not in use

I have a ZP100 connected to a couple of B&W speakers. I'm not using the line in.
I've noticed that there is a quiet hum when the amp is not in use. It's set up in the bedroom so is noticeable, is there anything I can do to stop this? I don't want to have to power it off and then wait while it warms up before I can listen, especially as in enjoying using it as an alarm.
