I've just read in WHFi that a sub will accept a high-level input by connecting straight to the amp's speaker terminals in parallel with the main speakers. I'm not sure what this means At the moment my sub, a Paradigm PDR10, is connected to the sub input on the AV amp which is driven by the NAD350 as a pre-amp. This means I can't use the sub for stereo only. I would like the sub to be used for stereo and believe that I can do it by the method described in the first paragraph. Can someone please help me with this?
