Passive Loudspeaker Distribution System
The
Zero Ohm ZOHM-4K-4 is a four-channel, high-power passive interface that allows amplifiers to safely drive multiple loudspeakers in parallel — even at impedance levels below 1 ohm. It replaces traditional 70V/100V transformer systems, offering full-range audio fidelity and reliable phase alignment across long cable runs.
Zero Ohm ZOHM-4K-4 Competitive Differences
- 4-channel, 4000W per channel passive speaker interface
- Runs parallel speaker loads at sub-1Ω without transformers
Zero Ohm ZOHM-4K-4 Description
The
ZOHM-4K-4, also called the "4K-4 Disruptor," delivers unmatched flexibility for complex loudspeaker arrays. This rackmount system connects between any amplifier and speaker network, enabling multiple speakers to be connected in parallel at extremely low impedances — safely and without compromising sound quality.
With support for speaker loads as low as 0.1 ohms, and compatibility with 2, 4, 8, and 16 ohm systems, the ZOHM-4K-4 provides integrators with a powerful alternative to conventional distributed audio solutions. It offers uniform power distribution across long cable runs and retains full-range performance from 20Hz to 20kHz — ideal for large venues, stadiums, and multi-zone environments.
Using standard Neutrik NL4 connectors and a clearly labeled I/O layout, the
Zero Ohm ZOHM-4K-4 ensures clean signal routing with precise channel control. Built in Canada, it’s a rugged, passive solution for high-demand professional installs.
