## Product Summary

The NC7FXX and NC7MXX are 7 pin XLR cable connectors developed for professional audio and multi-signal cable termination. This male and female plug set is commonly selected for tube microphone cables, broadcast gear and specialty audio harness applications where additional signal paths are required beyond standard XLR formats.

Built for reliable field use, the connector features a secure latch locking structure that helps maintain a stable connection during repeated mating cycles. It is well suited for studio cable assembly, equipment servicing and custom audio interconnect production, especially in systems that demand consistent signal integrity and dependable cable-end performance.

Compared with 3 pin XLR connectors used for standard balanced audio and 5 pin versions used in DMX or control lines, the 7 pin XLR format is better suited to tube mic power and multi-line audio transmission. This makes it a practical choice for engineers, cable assemblers and OEM equipment integration.

OEM/ODM customization is available for cable assembly and connector supply projects.
