Boxwave RCA Female to S-Video 4-Pin Male Audio Adapter

RCA to S-Video signal bridge

This compact coupler converts a single RCA female socket to a 4-pin S-Video male plug, letting you link legacy composite sources to S-Video inputs on TVs, monitors, projectors or capture devices. It is aimed at hobbyists and AV integrators who need a quick gender change without soldering or bulky cables. The passive design requires no external power and adds negligible signal path length.

Check your source and destination ports

Verify that the sending device actually outputs composite video through an RCA female jack and that the receiving equipment accepts a 4-pin mini-DIN S-Video signal. The adapter does not transcode between composite and S-Video formats, so both ends must natively support the respective signalling. Ensure the 4-pin layout matches your S-Video socket, as some variants use 7-pin or 9-pin connectors that will not mate.

Pocket-sized metal-shell construction

The coupler uses a black metal housing that shields the internal contacts and resists bending during frequent insertion cycles. Gold-plated pins on both sides reduce oxidation for reliable long-term contact. Its short barrel keeps the joint rigid, preventing cable weight from stressing panel-mounted ports on rack gear or wall plates. The package includes one unit, ready for immediate inline use.
