Many people are not aware of the existence of electromagnetic interference. The sources of natural electromagnetic interference are electrical discharges, dust and sand storms, precipitation and the cosmic radiation from either inside or outside the Solar System. Industrial interference comes from an electrical power grid, ignition systems, whirling machines, radio and TV receivers, power amplifiers, strip lightening, computers and from all kinds of transmitters. Interference can be emitted directly out of those devices in the form of an electromagnetic wave or it can penetrate a power grid.
The following filters were designed to be used with audio devices. The difference in electric properties of conductors resulted in the development of a unique filter for each group of cables.
The screening of the highly sensitive circuits and the accurate filtration of voltage are the basic methods of prevention against hum, noise and power grid interference. We are proud to present our four unique filters:
DFSS – Double Filtering Signal System
TFCT – Two Filters Current Tension
PFSS – Powder Filtering Signal System
DSS – Double Screen System
