The Channel Assignments and Faders panel in ARC DNA is essential for setting up proper signal routing, DSP behavior, and external controller compatibility. Using this tool, users tell the processor exactly where each speaker is located—front, rear, left, right, or custom zones—and define each channel’s role in the system (e.g., center or bass). This assignment data is critical for balance and fader controls to function properly, ensuring accurate front-to-rear and left-to-right signal shifting.

When connected to ARC Audio DSP controllers or iDatalink Maestro integration modules, this setup also allows external systems to identify which channels control which speaker types—enabling dedicated adjustments for subwoofers, center channels, and more using OEM radio controls or steering wheel inputs.

The Faders section of the panel gives users real-time control over front-to-rear signal movement and subwoofer levels (for properly assigned sub channels). When connected to Maestro modules, the DNA software automatically disables these software sliders, handing control over to the OEM interface for native-like system operation.

This panel bridges the gap between high-end DSP tuning and fully functional OEM or aftermarket controller ecosystems, making it a must-use step for proper integration and intuitive system control.
