Octave Audio Filter 3-P

To eliminate the problem of propagation of conducted electromagnetic interference, we developed the Filter 3-P, a filter system that acts directly in the path of the interference, namely the analog signal cabling

Today, modern hi-fi equipment can hardly function without digital signal processing. The classic CD player has largely become obsolete and has been replaced by internet-based sources, supplemented with hard drive storage media. In addition, signal connections to a network on a digital level are necessary to enable the components to work together.

This means that a modern system today has a large number of digital and analog signal connections, in addition to a large number of connections to the home network. In modern households there are also many systems and devices with switching power supplies (e.g. LED lighting systems, laptops, solar systems) and radio controls (such as WLAN, etc.)

All of these systems emit interference that affects the hi-fi devices and thus also the sound of the hi-fi system.
