Audio enthusiast and DIY-er Shawn Fogg has developed a passive 6-channel switch box to allow a receiver/processor with only one set of 5.1 analogue inputs to be hooked up to two sources with 5.1 analogue outputs. Optional remote cable and trigger available.
The new switchbox is a further development of Shawn’s analogue bypass solution for the Lexicon MC-1: http://smr-home-theatre.org/Lexicon/mc1/bypass.html
