The Architecture Behind Pinnacle

Smart Engineering That Simplifies System Design

Great loudspeakers don’t just sound good; they’re intelligently built from the inside out. With Pinnacle, K-array didn’t just design a new column array. They rethought how professional audio systems are powered, connected, and deployed.

The result is a platform that changed expectations for both portable sound systems and permanent installations. Pinnacle’s slim architectural form may be what first catches the eye, but it’s the internal electronics and system architecture that make engineers take notice.

High-Impedance Design: More Loudspeakers, Fewer Amplifier Channels

One of Pinnacle’s most practical innovations is its ability to operate at very high impedance. In real-world terms, this allows multiple columns to be daisy-chained from a single amplifier channel.

Depending on the model, a single amp channel can drive four to eight Pinnacle modules. That delivers immediate benefits:

• Dramatically reduced cabling

• Faster on-site installation

• Fewer amplifier channels required

• Lower system cost

• Easy scalability for different venue sizes

For rental companies and multi-space venues, this flexibility is invaluable. The same inventory can build compact systems for small rooms or combine into larger arrays for higher-output applications, all with coherent, predictable system behavior.

Less infrastructure. More adaptability.

Powering Pinnacle Without Traditional Amplifier Racks

Some Pinnacle configurations go a step further, removing external amplifier racks entirely.

Selected systems use an intelligent active subwoofer that not only powers itself, but also drives additional passive subwoofers and multiple column arrays. The sub effectively becomes the system’s central engine.

The advantages are significant:

• Only one main power drop required

• Loudspeaker cabling handles the rest

• No external amplifier racks

• Cleaner installs

• Faster setup and teardown

Unlike typical “active speaker” approaches, this architecture is purpose-built for professional deployment — combining simplicity with tour-grade reliability.

System Options That Fit the Application

Pinnacle offers multiple system architectures to match real-world needs.

• Fully passive systems driven by external amp racks

• High-impedance daisy-chained column configurations

• Intelligent powered-sub systems that eliminate amp racks

This gives integrators and sound engineers freedom to choose the topology that best fits venue requirements, outdoor installations, or internal technical preferences.

Choice without complexity.

A New Way of Thinking About Audio Connectivity

At its core, Pinnacle changes how professionals think about connecting sound systems.

Fewer cables.
Fewer rack spaces.
Fewer setup steps.
More output from smaller systems.
More predictable deployment.

It’s no surprise Pinnacle systems have been selected for premium theaters, performance venues, houses of worship, and corporate spaces worldwide where discretion, simplicity, and performance must coexist.

Engineering That Disappears, Performance That Doesn’t

Pinnacle’s architecture proves that smart internal design can remove friction from every stage of an audio project — from transport to rigging to tuning.

For engineers, installers, and venue operators, that means:

• Easier system planning

• Faster installs

• Cleaner technical rooms

• Scalable system growth

• Consistent sonic results

That’s what happens when engineering serves the workflow, not the other way around.
