Zero Ohm ZOHM-2K-2 2000W Per Channel Passive Loudspeaker Distribution System

The Zero Ohm ZOHM-2K-2 is a 2-channel passive loudspeaker distribution system that connects any amplifier to multiple speakers in parallel — handling up to 2000W per channel without overloading the amplifier or degrading audio quality. By supporting output impedances as low as 0.1 ohms, the ZOHM-2K-2 eliminates the need for 70V/100V transformer systems while delivering full-range 20Hz–20kHz performance across large installations.

Known as the "2K2 Renegade," this interface is engineered for audio professionals managing multi-zone speaker distribution for houses of worship, large venues, and complex installed sound environments. Unlike transformer-based solutions, this passive speaker distribution system preserves phase accuracy across all channels and imposes no coloration on the signal — making it a compelling choice for anyone seeking a transformer-free audio distribution solution that scales without compromise. It accepts speaker loads of 2Ω, 4Ω, 8Ω, or 16Ω, giving integrators maximum flexibility when specifying mixed speaker arrays.

Built in Canada and housed in a durable rackmount chassis with pre-installed rack ears, the ZOHM-2K-2 connects via industry-standard Neutrik NL4 Speakon connectors on both input and output — a wiring standard trusted by touring and installed sound professionals worldwide. With no digital processing, no active components, and no signal path compromises, the ZOHM-2K-2 simplifies even the most demanding parallel loudspeaker array designs while maintaining the amplifier headroom and phase integrity that high-fidelity installations demand.

Key Features of the Zero Ohm ZOHM-2K-2 Passive Interface

• 2000W Per Channel Power Handling: Manages high-output amplifier signals across parallel speaker loads without stressing the amp or sacrificing headroom in large-scale installations.
• Transformer-Free Design: Eliminates 70V/100V distribution transformers entirely, preserving full-range frequency response and removing a common source of signal coloration and bandwidth limitation.
• Sub-1Ω Impedance Compatibility: Supports minimum output impedances down to 0.1 ohms, enabling parallel connection of multiple loudspeakers that would otherwise overload a standard amplifier output.
• Universal Speaker Load Compatibility: Works with 2Ω, 4Ω, 8Ω, and 16Ω speaker loads, giving system designers flexibility to mix cabinet types within a single distributed audio system.
• Full-Range 20Hz–20kHz Frequency Response: Delivers uncompressed, wideband audio across all connected speakers — critical for music-forward applications in houses of worship and performance venues.
• Phase Alignment Across All Outputs: Maintains consistent output phase across amplifier channels, ensuring coherent sound reproduction in multi-zone and long-cable-run installations.
• Neutrik NL4 Speakon Connectivity: Features industry-standard locking Speakon connectors on both input and output for reliable, roadworthy connections in permanent and touring installations alike.
