Thanks @glennlake . I too am worried I might overheat my pi. I have heatsinks, but that is about it. I decided I will plug my Monitor into the control socket and the Pi into "Constant", speakers into the slaved sockets. I am going to install a power button onto the pi and the monitor has auto sleep mode. So when the pi is turned on the screen comes on and that triggers the speakers. When I turn off the pi, the tv goes into low power mode, shutting down the speakers. That's my plan anyway.
