When you turn off your 57 you shouldn't see any lights next to input switch.
When you turn on your 57 the lights are telling you what your control source is selected as.
You want to plug your turntables or cd decks into the control source selected.
For example: by default the control source is 1 and 3. That means you'd want to plug your TTs or CD decks into inputs 1 and 3 on the back of your mixer.
You can change the control source in the Hardware tab of the Setup screen.
