STA333BW
Biquad coefficient link
Table 30. Biquad coefficient link
Bit R/W RST
Name
4
R/W
0
BQL
Description
0: each channel uses coefficient values
1: each channel uses channel 1 coefficient values
For ease of use, all channels can use the biquad coefficients loaded into the Channel-1
coefficient RAM space by setting the BQL bit to 1. Therefore, any EQ updates only have to
be performed once.
Dynamic range compression / anticlipping bit

DRC
0: limiters act in anticlipping mode
1: limiters act in dynamic range compression mode
Both limiters can be used in one of two ways, anticlipping or dynamic range compression.
When used in anticlipping mode the limiter threshold values are constant and dependent on
the limiter settings. In dynamic range compression mode the limiter threshold values vary
with the volume settings allowing a nighttime listening mode that provides a reduction in the
dynamic range regardless of the volume level.
Zero-detect mute enable

1
ZDE
Description
0: automatic zero-detect mute disabled
1: automatic zero-detect mute enabled
Setting the ZDE bit enables the zero-detect automatic mute. The zero-detect circuit looks at
the data for each processing channel at the output of the crossover (bass management)
filter. If any channel receives 2048 consecutive zero value samples (regardless of fs) then
that individual channel is muted if this function is enabled.
Submix mode enable
Table 33. Submix mode enable
Bit R/W RST
Name

R/W 0
SME
Description
0: submix into left / right disabled
1: submix into left / right enabled
