Radial Engineering Rackmount Keyboard Mixer with 4 Stereo Inputs, redundant USB, and linkable design, built for flexible mixing and connectivity, (R800 1428)

The Radial Engineering KL-8 is a professional rackmount keyboard mixing station designed for complex stage rigs and studio setups that require multiple keyboard sources, flexible routing, and reliable performance control. Built as a high-density solution for touring musicians and production environments, it combines an 8-channel summing mixer, USB audio interface, and advanced linking capabilities in a single 1RU rack unit.

At its core, the KL-8 features four stereo keyboard inputs (8 channels total), each with independent level control and high-headroom circuitry for clean, transparent mixing. This allows seamless integration of multiple synthesizers, digital pianos, and sound modules while maintaining consistent signal integrity across all sources.

The integrated summing mixer provides a powerful master output section with balanced XLR connections for direct integration into PA systems or recording setups. A built-in USB audio interface enables direct connection to computers for recording, playback, or virtual instrument integration, making it ideal for hybrid live/studio workflows.

For mission-critical setups, the KL-8 includes redundant USB connectivity and linkable architecture, allowing multiple units to be cascaded for expanded channel capacity. This makes it especially suitable for large touring rigs and professional stage productions requiring scalable keyboard management.

Housed in a rugged 1RU steel chassis, the KL-8 is engineered for durability, reliability, and consistent performance in demanding environments.
