Introduction
JBL VTX Series subwoofers come equipped with Neutrik STX-Series speakON type connectors for connectivity to ampli-
fiers. Depending on the application and available cables, a number of wiring schemes can be used to achieve the de-
sired flexibility while using the least amount of cables.
This document outlines wiring techniques used for powering JBL VTX Series subwoofer products with Crown I-Tech HD
series amplifiers.
Internal VTX Subwoofer Wiring
All VTX series subwoofers (with the exception of the VTX F18S) have the two woofer components independently wired
to the input panel NL connectors. One woofer is connected to Pin 1 (±) and the other to Pin 2 (±). The same pin config-
uration is used for NL4 and NL8 connectors, giving the user the choice to use either type of cable. For the case of NL8
connectors, Pins 3 and Pins 4 are wired as pass-through connections (straight from one connector to the other) and
are not used to drive the subwoofer components.
