Bass Redirection
The KD16902 offers the bass redirection function for the consumers with small satellite speakers for some
channels. Dolby offers several output configurations for bass management. The KD16902 can perform the bass
redirection all configurations required by Dolby. This feature saves cost for the DVDP or any other system with
Dolby Digital decoder because the system does not require separate circuit for bass management.
Figure 15 to Figure 18 shows the output configurations required by Dolby. Please note that the KD16902 does not
offer analog amplifying gains for LFE signals. These have to done by the analog circuit in the system. The surround
inputs to the summing stages in Figure 15, Figure 16, and Figure 18 is removed for Dolby Pro Logic Mode.
