Hosa NBR-321 — 75-Ohm BNC to RCA Coupler Adapter
NBR-321 Overview
The Hosa NBR-321 is a 75-ohm coaxial coupler that adapts a male BNC connector to an RCA jack, providing a reliable signal path between professional video infrastructure and consumer video components. It is purpose-built for situations where pro video gear must interface with RCA-terminated equipment without introducing impedance mismatches. This adapter is well-suited for broadcast technicians, system integrators, and AV professionals who routinely work across mixed signal environments.
Compact and passive by design, the NBR-321 installs instantly with no tools required, making it a practical addition to any technician’s kit for field work or permanent installations.
