What is the function of the 225L module in relation to channels?

The 225L module serves as a dynamic processor, which means its primary function involves managing the dynamics of audio signals. It typically employs compression techniques to control the amplitude of signals, ensuring that the output levels are consistent and without unwanted peaks. This is essential in audio production as it allows for greater control over the mix, helping to prevent distortion while enhancing clarity and presence.

Dynamic signal processing is crucial for managing how signals interact in a mix and ensuring that each element is audible without overpowering others. While the module may incorporate aspects of other processing types, its main functionality is focused on dynamic control rather than equalization, sweeping filters, or exclusively compression. Each of these other functions can exist within a different context or module but not as the primary purpose of the 225L.
