Passive Loudspeaker Distribution System

The Zero Ohm ZOHM-2K-4 is a 4-channel passive interface designed to connect any amplifier to multiple loudspeakers — regardless of impedance — without concern for load balancing or cable length. It eliminates the need for traditional transformer-based systems while preserving full-range audio fidelity and safe, reliable distribution at ultra-low impedances.

Operates without transformers — supports sub-1Ω speaker loads

Zero Ohm ZOHM-2K-4 Description

Also known as the “2K-4 Renegade,” the ZOHM-2K-4 provides powerful, flexible, and scalable speaker distribution without the typical load limitations found in traditional audio systems. It enables parallel wiring of multiple loudspeakers across four independent channels, all while maintaining phase consistency and delivering clean, full-range audio from 20Hz to 20kHz. Whether you're designing a complex multi-zone audio installation or need long-distance coverage without transformers, the ZOHM-2K-4 is purpose-built to handle it — compatible with speaker loads as low as 0.1 ohm and supporting 2, 4, 8, or 16 ohm systems. Built in a rugged 2RU chassis with Neutrik NL4 connectors, it integrates seamlessly into pro audio racks for touring, installation, or fixed venue use. The Zero Ohm ZOHM-2K-4 is an ideal solution for integrators working in stadiums, arenas, houses of worship, and other environments requiring distributed sound with minimal infrastructure and maximum audio integrity.
