Ansuz Sortz BNC Supreme (used)

ANSUZ "SORTZ".

The effective anti-aerial noise-reduction system for your hi-fi.

These new SORTZ from Ansuz are used in unused input/output terminals on your components.
The effect of using these new innovative SORTZ is an audible reduction of noise primarily originating from airborne radio-frequency interference.
The unused inputs/outputs act as antennas that pick up exactly this type of noise. The noise is eliminated through the use of proven Tesla coil technology and anti-aerial technology.
Ansuz SORTZ are available in the following versions: RCA, BNC, XLR, USB, LAN.
