Sony 280GTX schematic/info


2007-08-10 1:29 pm
I'm building an equalizer that will interface with my Sony's speaker-level inputs. I need to know what the input impedance is, and can't find the information in my manual; from what I have heard this impedance can vary pretty wildly from one amp to the next, so I was wondering if anyone knew any trends within Sony or had the schematic for this amp (280GTX) itself. It would be a huge help. Thanks for any suggestions!
