Neutrik Connectors

Neutrik connectors are the plugs fitted to the end of a cable to make up professional audio, loudspeaker and mains power leads. This page holds Neutrik 3-pole XLR line connectors, 2-pole and 4-pole Speakon cable connectors for loudspeaker lines, and Powercon locking AC mains connectors. All of them have strain relief, so the choice comes down to the signal, the pole count and the diameter of the cable.

Choosing Neutrik Connectors

Match the connector to what runs through the lead first (audio signal, loudspeaker power or mains), then check the pole count and the cable it has to grip.

XLR line connectors

The NC3FXX 762.122UK and the NC3MXX are 3-pole XLR line connectors in the standard metal version. The NC3FXX and NC3MXX have a flexible rubber cable protector and are made for cables of 8mm diameter or less.

Speakon loudspeaker connectors

Speakon is the twist lock connector used on loudspeaker lines. The NL4FXX 763.481UK is a 4 pole cable connector with screw terminals and a chuck type strain relief for cable diameters of 6 to 12 mm and 10 to 16 mm. The NL2FXX 763.483UK is a 2 pole connector for 6 to 12 mm cable, and it is compatible with both 2-pole and 4-pole chassis connectors. Each Speakon here carries a current rating of up to 37 A rms.

Powercon mains connectors

The NAC3FXX Powercon is a single phase (3 conductor) lockable AC mains cable connector with a screw terminal assembly. It replaces appliance couplers where a rugged, locking connection is needed, and it has circuit breaking capability when mated with Powercon XX Series receptacles. Power-in versions are blue and power-out versions are grey, with different keying so the two cannot be intermated.

Frequently asked questions

What is a Neutrik Speakon connector?

A Neutrik Speakon connector is a twist-lock plug designed for loudspeaker lines, carrying amplifier power to speakers more safely than a jack plug. It latches firmly and keeps its live contacts shielded inside the housing. Two-pole and four-pole versions exist, and a two-pole cable plug can mate with a four-pole chassis socket. The range here includes Speakon cable connectors for loudspeaker leads.

What is a Neutrik Powercon connector?

A Neutrik Powercon connector is a locking AC mains connector used on stage lighting, amplifiers and other touring equipment in place of a standard appliance coupler. It twists to lock, so a lead cannot be pulled out by accident. Blue power-in and grey power-out versions are keyed differently to prevent mix-ups. The range here includes Powercon cable connectors for two cable diameter ranges.

How do you wire a Neutrik Speakon connector?

Wire a Neutrik Speakon connector by fitting the cable cores into the insert's screw terminals and then assembling the housing around them. Slide the bushing, chuck and housing onto the cable first, strip the cores, and connect positive to a plus terminal and negative to its matching minus terminal. Push the insert home and tighten the bushing to grip the cable. Check the maker's instructions.

What is a Neutrik connector?

A Neutrik connector is a professional cable connector made by Neutrik, the Liechtenstein maker that developed Speakon and Powercon and also makes XLR connectors. They are fitted to cable ends to make up microphone, loudspeaker and mains leads for live sound, installations and broadcast work. Pick a type for the job, such as XLR for line signals or Speakon for speakers.
