3.5 Using the DRC Function:
TAS5731 has two DRC blocks DRC-1 and DRC-2. Left and Right channels are processed using DRC-1,
and the sub-channel is processed via DRC-2. The DRC blocks on the TAS57X1 GUI are highlighted in
Fig-16 below. A single-click on the DRC block brings up the I2C register information in the properties
window as seen in
Figure 16 . The default state of the DRC control is in disabled state, as seen in the
runtime properties section of Figure 16 . To use the DRC function in the GUI, the DRC control should be
updated to the Enabled state. Note that the DRC-1 and DRC-2 have independent enable/disable controls.

The different parameters of the DRC such as Threshold, Compression, Offset and attack/decay time
constants can be programmed using the DRC customization tool, which is opened by double clicking the
DRC block on the GUI window.
Figure 17 shows the controls for DRC-1, with the user programmable
inputs highlighted. The plot on the right estimates the output vs. input level corresponding to the user
input(s).
