Zero-detect mute enable
Table 34.
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.

Max power correction
Table 37.
Setting the MPC bit turns on special processing that corrects the STA333BWQS power
device at high power. This mode should lower the THD+N of a full DDX system at maximum
power output and slightly below. If enabled, MPC is operational in all output modes except
tapered (OM
the line-out channels.
