Description
The PB 4×4 PRO USB employs ART’s Advanced Power Filtering (APF). This powerful technology utilizes both common mode and differential mode topologies in series, which minimizes unwanted noise between the AC line and ground, along with both sides of the AC line. The PB 4×4 PRO USB purifies the electrical current that reaches your gear, eliminating noise above 10kHz, while attenuating noise above 100kHz by over 40dB. Ground loop problems are also diminished.
