Klark Teknik KT-QFLEX ISOLATOR Isolation Module for QFLEX Column Loudspeakers

$179.00

The QFLEX ISOLATOR has been designed to resolve issues that often arise when large VNET systems are put into operation. It is specifically advised in situations where: the possibility that mains earth potentials exceeding +/-15V may exist between network nodes; electrical noise and interference may be present on the network cables, or wiring faults may exist on the network cable; the installer wishes to create networks that have a large “star” topology; or the network utilises screw terminal terminations.

About the Klark Teknik KT-QFLEX ISOLATOR Isolation Module for QFLEX Column Loudspeakers

The Klark Teknik KT-QFLEX ISOLATOR is a dedicated interface module designed to enhance the performance and safety of QFLEX column loudspeaker arrays in demanding professional audio environments. Its primary function is to provide high-quality ground lift isolation, effectively eliminating disruptive ground loop hum, buzz, and other electrical interference that can compromise audio clarity. By breaking the direct electrical ground connection between the mixing console or audio source and the powered loudspeakers, it ensures a clean, noise-free signal path.

This unit is specifically engineered for integration with systems utilizing QFLEX active column speakers, offering a streamlined solution for permanent installations, live sound, and corporate AV applications where multiple amplifiers and signal sources are present. The isolator helps protect sensitive audio equipment from potential voltage differences and mitigates the risk of damage caused by ground faults. Its transparent design aims to preserve the full frequency response and dynamic range of the original audio signal without introducing coloration or loss.

Housed in a compact and robust metal casing, the module is built for reliability on the road or in fixed installations. It features straightforward analog connectivity, making it simple to insert into an audio signal chain. The KT-QFLEX ISOLATOR is a practical tool for system technicians and installers seeking to resolve persistent ground-related noise issues and achieve a pristine, professional-grade audio output from their column array systems.
