2.2 Process Flow 1

This process flow supports a maximum internal sample rate of 48kHz. It is intended for stereo speakers where the 3-Band DRC uses individual coefficients for left and right. It is possible to tune the left and right Biquads (BQs) in the 12BQ bank and in the two post-EQ blocks individually between left and right. Hybrid modulation and class-H control are supported in this process flow.

Figure 2-1 depicts the signal path of this flow. The blocks below correspond to the functions found in the PPC3 GUI.
