Fidelity Audio offer a range of filters to suppress mains-borne noise, high voltage transients and surges.
Plug mains filters in next to your system and it will create a "noise free" area around it. You will hear more detail and see better pictures. Use more filters and the benefits will accumulate with the mains becoming cleaner still. Each filter is designed and built in the UK and made to order, no cloak and daggers just good quality filters at a sensible price!
Dirty Electricity or Mains Noise (RFI) - The Blurb!
The quality of the electricity we use in our homes and places of work has gone down significantly.
The electricity supply is now far more polluted than it ever was previously, via a myriad of WiFi, SMPS (switch mode power supplies - wal wart), Industry power drain, communication devices, monitoring signals that are now loaded into the mains wiring. All the wires in our homes are now increasingly leaking high voltage high frequency spikes. Many modern electrical appliances such as Routers, Blu Ray players, TVs, dimmer switches, low energy light bulbs, Pc and laptop computers pollute the house and neighbourhood via the local wiring. Most of this is backward noise generated by SMPS power supplies.
Dirty Electricity or Mains Noise may be new to you but it is probably the most recently recognised form of Electromagnetic pollution and still very poorly understood, but a good description would be radio frequency on the wires created by poor supplies and by your own and often your immediate neighbours hi tech electronics.
Electricity is supposed to flow in its original sine wave form but increasingly our appliances mess with it as complicated micro chips get in its way or we limit its path with dimmer switches, SMPS or clever low energy light bulbs steal the power from the peak of the wave. These type of actions (RF radiation) create reverberations that travel back along the formerly clean wires (just like the ripple in a pond when dropping in a pebble) that are supposed just to carry the clean 50 Hz signal creating a mechanism for previously local electric and magnetic fields to invade living spaces. All of this impacts on the quality of your HiFi and home cinema performance.
