Harmon Kardan hk690i

I purchased an HK 609i receiver but I am puzzled by the speaker hookup terminals - they look like all insulator! Any guidance?

I think it uses a type of binding post. You can unscrew them, then push the wire through a hole; look for a slot at the back of each post. Tighten by screwing the post clockwise. Or, you can use 'banana' type jacks, but these need to be connected to the ends of your speaker wires.

Make sure there are no wires touching each other.
