Performance XLR Cables Io Audio Technologies Performance XLR Cables utilize two stranded, 24AWG, OFC connectors in a tight-pitch twisted pair configuration. The PE insulation reduces the capacitance, while a spiral copper shield provides excellent EMI and noise rejection. A sturdy, black PVC jacket is designed to take the abuse of any environment. The IO-XLR3-M-BK and IO-XLR3-F-BK connectors feature durable die-cast zinc shells with built-in latch locks provide a reliable connection when mated with the opposite gender. The cables also feature a sturdy plastic insert that tightens onto the cable to provide strain relief, while an additional rubber boot delivers extended support from excessive bending. Silver-plated contacts ensure a reliable signal every time.
