NEUTRIK XLR MALE CONNECTOR

NEUTRIK XLR MALE CONNECTOR – XX Series 3-Pole Male Cable Connector

The NEUTRIK XLR MALE CONNECTOR (part reference NC3MXX / XX Series) is the world-renowned standard 3-pole male cable XLR connector. Built specifically for high-performance balanced audio transmission, studio recording, live sound reinforcement, and DMX lighting control systems, the NEUTRIK XLR MALE CONNECTOR combines robust mechanical engineering with continuous signal conductivity.

As shown in the product image, the connector features a rugged diecast zinc body with a sleek nickel finish, silver-plated solid brass contact pins, a durable polyacetal chuck strain relief, and a polyurethane rear boot. Designed without locking windows on the male shell, it provides greater housing strength, improved durability, and maximum EMI/RFI shielding protection.

Key Features of the NEUTRIK XLR MALE CONNECTOR

Enhanced Shell Design: Engineered without a locking window to increase overall shell strength, durability, and resistance to impact on stage or in transport.
Superior Chuck-Type Strain Relief: Utilizes an upgraded polyacetal (POM) chuck clamp mechanism that delivers exceptional cable retention force ( $ge 220text{ N}$ ) and makes field assembly fast and reliable.
Low Resistance Machined Brass Contacts: Precision-machined solid brass male pins with heavy silver plating ensure ultra-low contact resistance and optimal conductivity over thousands of mating cycles.
Improved Ground Continuity: Features internal housing ground contacts that ensure firm shell-to-chassis electrical continuity, effectively preventing radio frequency and electromagnetic interference (RF/EMI).
Polyurethane Strain Relief Boot: The boot with a rubber gland gives high protection against cable bending stresses at the cable entry point.
Solder Barrier Contacts: Designed with solder cups featuring a barrier to prevent molten solder from running into the contact pin area during soldering.

Common Applications and Industrial Usage

The power handling, ruggedness, and signal purity of the NEUTRIK XLR MALE CONNECTOR make it an indispensable connector across multiple professional audio-visual sectors:

Microphone & Patch Cables: Serves as the male termination plug for balanced studio microphone leads, patch cords, and snake cables.
Live Sound & Concert Touring: Connects line-level outputs from mixing consoles, audio interfaces, active PA speaker systems, and stage boxes.
Studio & Broadcast Engineering: Used in broadcast facilities, recording booths, and mastering suites requiring noise-free signal paths.
DMX Stage Lighting Control: Widely deployed across 3-pin DMX signal chains to link lighting controllers, dimmers, and intelligent moving-head fixtures.

Assembly Guidelines and Best Practices

Assembly Tip: Always thread the polyurethane boot and slide the chuck clamp onto the cable before soldering wire leads to the contact pins.

Standard Balanced Pinout: Follow international pin assignments—Pin 1 (Shield / Ground), Pin 2 (Hot / Positive Signal), Pin 3 (Cold / Negative Signal).

Precision Soldering: Use a clean, temperature-controlled soldering iron ( $350^circtext{C}text{--}370^circtext{C}$ ) to quickly tin the solder cups and prevent overheating internal insulation.

Housing Tightening: Screw the rear boot onto the diecast shell until hand-tight; the internal chuck automatically clamps down on the cable sheath for reliable strain relief.
