Neutrik NC3MXX XLR Male Cable Connector

Neutrik NC3MXX XLR Male Connector

The Neutrik NC3MXX is a 3-pole male XLR cable connector, the current XX-series successor to the long-running X series and the standard termination on professional microphone and balanced line-level cables worldwide. It has a nickel-plated zinc diecast housing with silver-plated solder contacts, an improved locking recess, a chuck-type strain relief and a boot with a polyurethane gland that protects the cable against bending stress. If you build or repair your own cables, this is the connector that rental companies, studios and live sound engineers specify because it assembles quickly, solders cleanly and keeps working after years of plugging, coiling and transport.

Key features

• 3-pole male XLR cable connector from the Neutrik XX series
• Nickel housing with silver-plated contacts
• Rugged zinc diecast shell for stage and studio use
• Chuck-type strain relief for higher pull-out force
• Boot with polyurethane gland protects against bending stress
• Solder contacts accepting cable from 3.5 to 8.0 mm outside diameter

Built for repeated professional use

Neutrik rates the NC3MXX for more than 1000 mating cycles, with insertion and withdrawal forces held to 20 N or less, so the latch engages positively without fighting the user on a dark stage. The male connector has an improved locking recess without a window, which strengthens the housing at the point where older designs were vulnerable. The internal thread on the shell is protected against damage, and the sleek, ergonomic shell shape handles comfortably when you are patching a full stage box of cables under time pressure. Coloured rings and boots are available separately for coding cables by length, channel or owner.

Assembly and soldering

The connector assembles from a small number of parts with no screws to lose. Slide the boot and chuck onto the cable first, strip and tin the conductors, solder them to the generously sized contact cups, then tighten the chuck so it grips the cable jacket evenly and screw the housing together. The chuck strain relief clamps the whole cable rather than relying on the solder joints, which is what gives the finished cable its high pull-out resistance. The contacts accept wire up to 2.5 square millimetres, equivalent to 14 AWG, and the housing suits cable diameters from 3.5 to 8.0 mm, covering standard microphone and balanced line cables.

Electrical performance

Neutrik specifies contact resistance of 3 milliohms or less, capacitance between contacts of 4 picofarads or less, dielectric strength of 1.5 kilovolts DC and a rating of 16 amps per contact at up to 50 volts. In ordinary microphone and line-level service those figures mean the connector is never the weak point in the chain: contact integrity stays high, noise stays low and balanced lines keep their interference rejection from one end of the cable to the other, provided the cable itself and the female NC3FXX partner are in equally good condition.

Where it is used

One NC3MXX terminates the output end of a standard microphone cable, with an NC3FXX female at the other end. The same connector finishes balanced patch cables between mixers, processors, stage boxes and powered equipment, DMX lighting control cables in the 3-pole format where that standard applies, and custom looms built to length for studios and installations. Buy singles for repairs or multiples for a cable-building session; keeping spares in the tool kit means a damaged connector at a venue is a five-minute soldering job rather than a cancelled channel.

For cable builds and repairs where the connection has to stay quiet and secure for years, the genuine Neutrik NC3MXX remains the professional default for a male XLR termination.
