Figure 17. Output Configuration 3.
Figure 18. Simplified Configuration
The bass redirection function, shown in Figure 19, in the KD16902 can accommodate any output configuration. For
Dolby Pro Logic mode, the surround input to the bass summing stages can be removed by setting the
corresponding gain to zero. The processor needs the following parameters from the host to process a selected
configuration.
Sampling Frequency
Filter switches
Gain coefficients
LFE redirection switches
Following is the list of the commands needed for bass redirection function with the corresponding terms shown in
Figure 19.
