Echo Reference

The TAS2563 supports echo reference feedback. This data stream is a loopback of the digital audio that the amplifier is playing, just before it is processed by the digital-to-audio converter (DAC). It includes all effects produced by the smart amp features such as EQ, DRC, speaker protection algorithm, and so forth.

This feature allows the user to do noise cancellation or echo correction algorithms. Figure 2-1 presents the block diagram.
