This XLR 3-pin female ETI Brio connector is a top-of-the-range connector designed with top-quality components. The contacts are made of rhodium-plated tellurium copper for increased conductivity and resistance to oxidation and corrosion.

In this connector, ETI has corrected a recurring problem in many XLR connectors on the market, namely too much ground causing higher capacitance, which affects sound. The brand has also studied the question of pin thickness. The result of this research is that the best thickness for low-voltage connectors is 0.6mm. A greater or lesser thickness would have a negative effect on reproduction quality.

For the connector body, ETI uses brass and a PTFE dielectric insulator, a structure that not only reduces vibration but also rejects EMI/RF interference.
