Connecteur Neutrik NTR-NL4MMX

The Neutrik NTR-NL4MMX is a 4-pole lockable coupler designed to link two NL2/4F connectors for cable extension. Constructed from metal and polyamide with UL 94 HB rating, it provides a compact, durable solution for extending speaker and audio cables while maintaining secure electrical connections.

Advantages

This connector offers a lockable 4-pole mating that ensures stable connections between NL2/4F female connectors, enabling reliable extension of speaker or multi-pin audio cables. Its metal and polyamide construction gives mechanical strength and resistance to wear, and the compact dimensions (28.7 × 28.7 × 50 mm) make it suitable for installations with limited space.

Suitable for

• Extending speaker cables using NL2/4F connectors
• Temporary or permanent in-line cable joins in professional audio setups
• Multi-conductor audio connections requiring a four-pole link
