Neutrik Speakon 4-pole Panel Connector N-NL4MPRXX (30208512) round recessed mount

The Neutrik Speakon 4-pole Panel Connector N-NL4MPRXX is a recessed round panel mount connector designed for professional audio speaker and amplifier connections. It provides a locking Speakon interface that enables secure, vibration-resistant high-current signal transfer for public address systems, live sound reinforcement, and fixed studio or installation use. The recessed design reduces accidental disconnection and offers a compact footprint for permanent panel mounting in cabinets, racks, or speaker enclosures.

Advantages

This Neutrik Speakon connector offers a robust metal and plastic construction with a reliable locking mechanism that prevents accidental unplugging under load. The 4-pole contact arrangement supports parallel or bi-amped speaker wiring and allows for flexible wiring schemes. The round recessed housing protects the mating cable plug while maintaining an accessible connection point. The connector is engineered for frequent use and provides consistent electrical contact and mechanical stability in demanding audio environments.

Suitable for

• Permanent panel mounting in speaker cabinets and amplifier racks
• PA systems, stage and touring sound systems
• Studio installations and fixed commercial audio systems
• Bi-amping or multi-channel speaker wiring requiring 4-pole connections

When it may not be suitable

This recessed panel connector is intended for permanent installation and may not be suitable for applications where a temporary, frequently moved plug solution is preferred. It is not a replacement for connectors rated for exposure to weather unless installed in a suitably protected enclosure.

Key specifications

• Contact configuration: 4 conductors (4-pole)
• Mounting style: round recessed panel mount
• Contact type: locking Speakon interface for high-current audio signals
• Intended application: speaker and amplifier connections in professional audio
• Mechanical protection: recessed housing to reduce accidental disconnection

How to use

Install the connector into a compatible panel cutout and secure it according to the mounting instructions for a flush, recessed fit. Terminate speaker cable conductors to the designated 4-pole contacts using appropriate soldering or crimping methods and ensure correct polarity and secure connections. To connect, insert the mating Speakon cable plug and rotate until it locks; to disconnect, unlock and withdraw the plug. Verify continuity and polarity with a meter before applying power or signal for initial setup.

What to consider before purchase

• Ensure your panel or enclosure has the correct cutout size and depth for a recessed round mount
• Confirm 4-pole wiring is required for your speaker configuration (parallel, bi-amp, or multi-channel)
• Check that the connector’s mechanical and electrical ratings meet your amplification and current requirements
• Plan for indoor or protected installation unless additional weatherproofing is provided

Usage recommendations

Use compatible Neutrik Speakon cables and ensure firm, strain-relieved cable routing to maintain reliable electrical contact. Periodically inspect contacts for wear or corrosion and verify locking action to maintain secure, high-current speaker connections.
