2.3 Process Flow 2

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 BQs in the 14 BQ bank individually between left and right.

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