Liitin 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

How to use

Align each NL2/4F connector with the corresponding mating contacts of the NTR-NL4MMX and push together until the lock engages. For a permanent installation, attach the coupler firmly between two NL2/4F female connectors to extend cable length. Verify that all contacts are seated and that the locking mechanism is engaged before applying power or signal.

Recommendations

Use the coupler in dry, clean environments and avoid excessive mechanical strain on joined cables. Periodically inspect contacts and locking mechanism for wear; replace if corrosion or damage is found to maintain reliable audio performance.
