Neutrik Americas NLT4FXX Speakon STX-4 Connector

Product Description

The NEUTRIK AMERICAS NLT4FXX is a 4-pole Speakon cable-end connector with a nickel finish, designed for professional audio and speaker wiring applications. This cable-mount plug provides a secure, twist-lock connection between amplifier outputs and speaker cabinets or line arrays. It is built for use in demanding live sound, installed audio, and touring environments where reliable signal transfer and mechanical durability are required. Licensed audio technicians and professional AV installers are the primary users of this connector type.

The NLT4FXX is suited for 4-conductor speaker cable assemblies used in professional audio systems. It is typically installed at the cable end feeding passive loudspeakers, subwoofers, or biamplified speaker cabinets that accept Speakon-style locking connectors. Its nickel-plated housing provides corrosion resistance in stage and rack environments subject to regular handling and transport.

Installation Notes

Installation is performed by audio technicians or AV professionals using standard hand tools including a small flat-blade screwdriver for terminal clamping. Ensure the speaker system and amplifier are powered down and de-energized before terminating or replacing connectors. Strip and seat conductors fully into the terminal block before tightening clamping screws, and verify polarity assignments before final assembly. Follow applicable NEC guidelines for low-voltage audio wiring in installed sound applications.
