It's a basic mono cable as casouza stated. Go to radioshack. Be careful to go into the correct jack if the unit has in and out or you'll blow a fuse.
Setup 12V trigger for B&W DS7
I need help on setup dipoles on DS7 (spec as 12V trigger current requirement 45mA). I do have 12V trigger on Denon AVR-3805(DC 12V 25mA max). How can I hookup DS7 on 12V of Denon? If I have processor like sunfire grand theature II has 12V trigger, how can I setup? What cable should I use now?
