I have an older Sony Home Theatre (Model HCD-C-450) and I am hoping to use the built-in wall speakers of the house I recently bought. The wall plates are incredibly confusing and I'm not sure which connectors/adapters to use. The wall plate looks foreign to me, the jacks look like they require a cross between a coax and a banana plug. Could someone help me understand what these plates are and what inputs are required?
MANY THANKS!
