Input output
mapping/mixing
Each of the eight signal-processing channels input can be any ratio of the
eight input channels.
Each of the eight outputs can be any ratio of any two processed channels.
Each of the three
signal-processing channels or the
five pass-though channels inputs
can be any ratio of the eight input
channels.
Each of the eight outputs can be
any ratio of any of the three
processed or five bypass
channels.

TAS5028A
DAP Architecture Diagrams
Figure 1
4 shows the TAS5028A DAP architecture for Fs = 96 kHz. Note the TAS5028A bass management
architecture shown in channels 1, 2, 7, and 8. Note that the I
2
C registers are shown to help the designer
configure the TAS5028A.
Figure 1
5 shows the TAS5028A architecture for Fs = 176.4 kHz or Fs = 192 kHz. Note that only channels
1, 2, and 8 contain all the features. Channels 3
7 are pass-through except for master volume control.
Figure 1
6 shows TAS5028A detailed channel processing. The output mixer is 8X2 for channels 1
6 and *X3
for channels 7 and 8.
