0: Limiters act in anti-clipping mode
1: Limiters act in dynamic range compression mode
Both limiters can be used in one of two ways, anti-clipping or dynamic range compression.
When used in anti-clipping 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.

Setting of 1 enables the automatic zero-detect mute
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.
