Introduction
JBL VTX Series subwoofers come equipped with Neutrik STX-Series speakON type connectors for connecvity to ampli-
ers. Depending on the applicaon and available cables, a number of wiring schemes can be used to achieve the de-
sired exibility 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 ampliers.
Internal VTX Subwoofer Wiring
All VTX series subwoofers (with the excepon 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 cong-
uraon 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 connecons (straight from one connector to the other) and
are not used to drive the subwoofer components.
