XTC-333 – High-Speed HDMI Female-to-Female Coupler Adapter (4K Ultra HD, 1080p Full HD, Gold-Plated Contacts, Cable Extender Gender Changer)

Product Overview

The XTC-333 is a compact, high-performance HDMI (High-Definition Multimedia Interface) female-to-female inline coupler adapter manufactured by Xtech. Purpose-built for commercial surveillance control rooms, AV installations, desktop workstations, and home theater setups, this precision adapter joins two standard male HDMI cables end-to-end, extending the overall reach between surveillance recording units (NVRs, DVRs, XVRs) or PC workstations and high-definition video monitors without requiring the expense or labor of running an entirely new long-length cable.

Engineered to preserve digital signal integrity, the adapter features corrosion-resistant gold-plated connectors and contact pins that ensure optimal electrical conductivity, low contact resistance, and immunity against oxidation. The internal wiring maintains standard High-Speed HDMI pass-through architecture, supporting resolutions up to 4K UHD (3840 × 2160 @ 30/60 Hz), Full HD 1080p, 3D video, Audio Return Channel (ARC), and HDMI Ethernet Channel (HEC). Encased in a rugged, impact-resistant molded PVC housing with textured finger grips, the XTC-333 provides a secure, non-slip fit and dependable mechanical durability for tight installations behind flat-panel wall mounts, AV distribution racks, and wire conduits.
