What is the difference between soldered connectors and crimp connectors in video cables?
Soldered connectors are the preferred way to terminate “audio” cables, but not for analog video cables (which includes composite video, component video, s-video, RGB and RGBHV video). Especially in HDTV video transmission, high-bandwidth and crimp-on connectors are preferred because they retain the electro-mechanical relationship between a coaxial cable’s conductor and shield (ground) and this determines the accuracy of the impedance (measured in ohms). Soldering connectors onto cables used for HDTV creates an impedance mismatch (or bottleneck) that results in back-reflections inside the cable, and this negatively effects signal quality and decreases bandwidth.
