Product Overview
Neutrik NC3MX (cast as NC*MX on the shell) is a heavy-duty 3-pole male XLR cable connector engineered for balanced audio and data transmission. Built with a diecast zinc housing and an internal polyacetal chuck-type strain relief, it locks firmly onto cable jackets to protect internal solder joints from tension and bending fatigue.

Frequently Asked Questions
What cable outer diameter does this connector clamp?
The internal chuck strain relief clamps outer cable jackets measuring between 3.5 mm and 8.0 mm.
What wire gauge fits the solder cups?
The solder cups accept stranded wire conductors up to 14 AWG (2.5 mm²).
Why does the housing read NC*MX rather than NC3MX?
Neutrik uses the NC*MX casting across the entire X-series line, using the asterisk as a placeholder for contact count. The included 3-pole male insert defines this specific assembly as catalog number NC3MX.
The classic Neutrik chuck clamp has saved more live sets from accidental cord yanks than anyone can count. Solder it clean, thread the boot down tight, and let the signal run.
