Zero Ohm ZOHM-4K-2 | 4000W/Channel 2-Ch Passive Interface | Parallel Speaker Load at Sub-1Ω

Passive Loudspeaker Distribution System

The Zero Ohm ZOHM-4K-2 is a 2-channel, passive interface designed to connect any amplifier to multiple loudspeakers without the limitations of load impedance or cable length. This patented design eliminates the need for 70V/100V transformers while maintaining full-range audio quality and phase consistency, even across extremely long cable runs.

Zero Ohm ZOHM-4K-2 Competitive Differences

• Supports sub-1 Ohm impedance speaker loads
• 4000W per channel passive design with no transformers

Zero Ohm ZOHM-4K-2 Description

Formerly known as the MS-4R, the ZOHM-4K-2 — also referred to as the "4K-2 Disruptor" — is engineered to revolutionize large-scale speaker distribution systems. This passive unit connects between your amplifier and loudspeaker array, enabling parallel wiring of multiple speakers at combined impedances below 1 ohm, something that would traditionally overload most amplifiers. Thanks to its zero-ohm functionality, it works with any speaker impedance (2, 4, 8, or 16 ohms) and eliminates the need for transformers or complex impedance-matching hardware. The ZOHM-4K-2 ensures consistent phase alignment and full-range frequency response from 20Hz to 20kHz, delivering clean, high-output audio even over long-distance cable runs. Ideal for arenas, stadiums, worship centers, or multi-zone audio systems, the Zero Ohm ZOHM-4K-2 is a game-changing tool for integrators demanding scalability, simplicity, and sonic integrity in high-power distributed sound systems.
