Device overview

The second processing stage embeds a mixing block, a biquadratic/crossover filter, a DRC

stage, the volume control, a DC cut filter and a post scaler. Depending on the device

settings, the following configuration and features are available:



2.1 output with individually configurable anticlipper/DRCs (Figure 7): two individually

configurable DRC/anticlippers are available while the eighth biquadratic filter, jointly

with the mixer block, can be used to perform LFE. This configuration and features

ensure the backward compatibility with previous Sound Terminal® products.
