What is the purpose of the TC Icon in the System 6000 setup?

The TC Icon's primary function within the System 6000 setup is to serve as a remote control interface. This device allows users to manage various system parameters, settings, and controls from a distance, providing convenience and flexibility in operation. It facilitates easier access to features without requiring direct interaction with the main unit, making it especially useful in live sound scenarios or when the equipment is rack-mounted and not easily accessible.

While it's true that the System 6000 involves digital signal processing, which is essential for the device's operations—such as reverb and other audio effects—the specific role of the TC Icon is fundamentally to enhance the user experience through remote control capabilities. This means direct manipulation of various processing elements is done via the TC Icon, allowing for real-time adjustments and a more intuitive workflow.

In this context, choosing digital signal processing as the answer overlooks the TC Icon's true purpose in the setup, which directly ties into user interaction and management of the system rather than the processing of audio signals themselves.
