The supplied product information refers to a report on the ZeroPlug™M in Stereo 5/2007. Black Forest Audio describes its use and the perceived effects as follows:
Anyone familiar with the ZeroPlug™C will recognise what happens when unused sockets throughout the electrical circuit are closed with the ZeroPlug™M. According to Black Forest Audio, the effect is almost twice as strong.
Start with your system by closing the unused Schuko sockets in its mains distribution block. You can then move on to the unused wall sockets elsewhere in the room.
The manufacturer suggests disconnecting another device, such as a switched-off computer, from the mains while listening to music and fitting a ZeroPlug™M into the vacated socket. According to Black Forest Audio, even sockets located further away can still have a noticeable influence.
The letter C stands for cinch, also known as RCA; M stands for mains.
Black Forest Audio also describes effects in video and surround systems. The manufacturer mentions smoother areas of colour, flicker-free edges and richer colours with a greater sense of depth as potential improvements to picture reproduction. Black Forest Audio recommends trying this in your own system.
