Product Overview

This dual-channel XLR RF filter connector is designed for balanced audio signal feedthrough and RF isolation in shielded test environments.

It integrates two standard XLR female connectors within a fully enclosed, precision-machined aluminum alloy shielding enclosure. Installed through the wall of a shielded box or RF/EMC test chamber, the connector enables balanced audio signal transmission between the inside and outside of the enclosure.

The built-in RF filtering structure helps suppress conducted RF interference and RF leakage along audio cables, reducing RF leakage through cable openings and maintaining the shielding effectiveness of the test enclosure.

The connector is suitable for RF, acoustic, and EMC testing of audio products such as speakers, Bluetooth headphones, microphones, and other professional or consumer audio devices.
