You can also just stick the wires through the holes, not too far, just so
they're clear through and you can feel the end on the bottom and tighten
down the plastic knob. These are, as I recall, binding posts. The hole
in the front is made for banana plugs. Wrapping the wire on those
doesn't usually work that well, just put the wires t through the holes.
