TWISTED SERIES GROUND CABLE
T-Adler develops ground cables because we need the cable to transfer all the dirty electrons from the audio or video system to the EarthMan 6. To clean up the ground section of the path, we select the low impedance material so that all the noise will go away to the EarthMan 6 as fast as possible.
Capacitors are also effective in shunting higher frequencies to ground if the circuit allows. Shields shunt radiated and induced noise to ground. We do it all the time.
