6.4.6

Dynamic range compression/anti-clipping bit

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.

6.4.7

Zero-detect mute enable

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.
