I am also very interested in getting hold of an autonomous signal sensing RCA to powerlink trigger box. I’ve just purchased 5 Beolab speakers for my home cinema system including a 7.2 for centre. Just waiting with baited breath for them to arrive on Wednesday. I’ve purchased them from a second hand B&O specialist who has made me up a Powerlink trigger cable which will be driven from my TV’s USB socket, which seems like the next best thing in a home cinema application, but a signal sensing trigger box would be ideal so I don’t have one annoying visible cable going up to the TV!
