I am also very interested in getting hold of an autonomous signal sensing RCA to powerlink trigger box. Iโve 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. Iโve purchased them from a second hand B&O specialist who has made me up a Powerlink trigger cable which will be driven from my TVโs 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 donโt have one annoying visible cable going up to the TV!
