Hi there, hope you can help me get of this puddle. Essentially, I own a set of Bose Companion 5 speakers. Recently I have been discussing AV receivers with friends and was gifted a Pioneer VSX 527K receiver. The receiver does a 5.1 speaker setup. It also has an active subwoofer output and what looks like a left & right RCA stereo speaker outputs. (http://www.pioneer.eu/images/product...rear_large.jpg) The problem is that the Bose speakers will only take input through USB (simulated 5.1) or stereo thorough a 3.5 mm jack. I have been doing lots of googling but can't figure out how to connect the two. Do I need to buy an Analog to Digital Converter (the guy at Maplin suggested this) ? If so, how can I make use of the simulated 5.1 through USB ? Any other creative ideas ?
