ProX XC-NL4FR4 — 4-Pole Female SpeakON Panel-Mount Connector
XC-NL4FR4 Overview
The ProX XC-NL4FR4 is a 4-pole female SpeakON connector designed for professional loudspeaker and amplifier cable assembly applications. Built to the industry-standard NL4 form factor, it features solid contacts with screw-type terminals and chuck-type strain relief for long-term cable grip and durability. The touch-proof quick-lock contact system prevents arcing and shorting during connection or disconnection under load, providing a fail-safe condition for both equipment and operator. This connector is suited for touring engineers, system integrators, and studio technicians who require reliable, repeatable speaker connections.
The precision-molded composite housing and locking latch deliver consistent mechanical integrity across heavy-duty stage, touring, and studio environments, and the connector is compatible with all standard NL4 SpeakON panel receptacles.
