Description
Neutrik NC3MXX – 3‑Pole Male Inline XLR Connector (Nickel Housing)
Overview
The NC3MXX is part of Neutrik’s XX series of XLR cable (inline) connectors. It is a 3‑pin male (plug) connector intended for solder‑termination of balanced audio cables. Its nickel‑plated zinc die‑cast housing, improved strain relief, and refined mechanical design make it an excellent choice for pro audio cable assemblies and repairs.
As an authorized distributor, Tri‑Tek Electronics offers genuine Neutrik parts with full warranty support and local availability for customers in Mesa, Phoenix, Chandler, Gilbert, Tempe, and the greater Arizona area.

Usage / Application Scenario
The NC3MXX is ideal for creating or repairing balanced audio cables, such as microphone lines, stage snakes, or custom audio harnesses. During assembly, the installer slides the boot and strain relief onto the cable, solders the conductors to the connector’s solder cups, and secures the internal components with the chuck-style strain relief. The result is a durable, flexible cable that withstands regular use in both studio and stage environments.
An installer might use this connector to fabricate custom-length XLR cables for a stage rack, where consistent performance and mechanical durability are critical. The high mating cycle rating makes it particularly suitable for touring and live audio setups.
Tips & Best Practices
-
Pre‑tin both wire ends and connector solder cups before final soldering
-
Avoid overheating the insert during soldering—use a temperature-controlled iron
-
Ensure the strain relief clamps the cable jacket, not just the conductors
-
Pair with XX-series female connectors for best mechanical and electrical fit
-
Add color-coded boots or rings for system organization and channel identification
