Advanced Audio Processing Features in TAS5709
Turn it ON. Then L-R terms gets mixed with raw L and R after band-pass filtering. L-signal is RED, R-
signal is BLUE and L-R-signal is BLACK.
Biquads and mixers can be adjusted to fine-tune 3D.

Bass Boost (Pseudo Bass): ON/OFF
(L+R)/2 signal is low-pass filtered to get the Bass signal and then applied a boost before mixing with L
and R channels.
3.
Two-Band DRC (2-band DRC): ON/OFF
L and R signals are split into two paths: one path with high-frequency components (high pass) and the
other with low-frequency components (low pass).
High frequency of both L and R has one DRC-ganged and low-frequency paths have another DRC-
ganged. This allows both high- and low-frequency components to have different thresholds.
