Hi, First you need to check you have a FULL ambio box: most of the ones I've seen are often missing the speakers plugs and have bare wires. Then You have male/female plugs. you plug this into your amp speaker out and plug in the female part the main speakers. Given the electronics re not to aged and would need  a refresh, this how it works: You have the speaker outs from the box where you plug the "ambio" speakers that should be placed on the sides (not behind). Refer to an ambio Beomaster owner's guide like the 1001 for details on the ambio effect. It's not a an obvious effect and, as far as I've experienced it, very depending on the source music. The difference between the ambio and the ambio filtered (the one with the waves) was never obvious to me but I'm not good at audio subtleties. Hope this helps.
