Dual FreqInOut FO1_2RK redefines how outboard audio gear integrates with modern DAW workflows by turning external hardware into fully recallable plugins.

Traditionally, working with analog hardware involves complex routing, manual latency compensation, and external configuration—slowing down workflow and making session recall difficult.

FO1_2RK simplifies this process.

With 8 inputs and outputs in a 1U rackmount format, FO1_2RK connects via USB-C and works alongside your existing audio interface on Mac and Windows—no aggregate devices or complex routing required.

Using the FreqInOut plugin, all routing, latency compensation, and hardware control are handled directly inside your DAW. Audio is processed in 32-bit with sample-accurate timing, allowing outboard gear to behave like native plugins as part of your session—with precise sync, even when recording.

The system includes Hardware Mix for parallel processing, M/S mode for mid-side workflows, and an analog matrix for flexible signal routing between connected hardware.

FO1_2RK is fully expandable – combine up to four units for up to 16 inputs and outputs, supporting larger studio setups and more advanced workflows.

FO1_2RK is more than an interface – it’s a complete hardware integration system that bridges the gap between hardware and software, enabling faster, more flexible, and fully recallable workflows for modern production environments.

TECHNOLOGY:

• Dual FreqInOut FO1_2RK uses Freqport’s proprietary Analog Harmony Technology to stream audio between hardware and your DAW with sample-accurate timing over USB-C.
• Latency is automatically managed within the plugin, ensuring phase coherence and tight synchronization across all channels.
• The system integrates directly into your DAW environment, allowing hardware routing, processing, and recall to function as part of your session, rather than as external infrastructure.
