at the input data to each processing channel after the channel-mapping block. If any channel receives

2048 consecutive zero value samples (regardless of fs) then that individual channel is muted if this func-

tion is enabled.

Sub-Mix Enable

Setting the SME bit enables a scaled-mix of the content from the Sub channel (i.e. channel 3) into the main

Left & Right channels (i.e. channels 1 & 2). The Sub-Mix resides post-volume & gain compression pro-

cessing.

7.6.1

Max Power Correction Variable

By enabling MPC and setting MPCV = 1, the max power correction becomes variable. By adjusting the

MPCC registers (address 0x27-0x28) it becomes possible to adjust the THD at maximum unclipped power

to a lower value for a particular application.

Max Power Correction

Setting the MPC bit corrects the STA500/505/508 power device at high power. This mode will lower the

Noise Shaper BandWidth Selection

DDXi-2101 provides the ability to the user to select two types of noise-shaper order. This facilitates the

user to essentially make the appropriate bandwidth selection for their design thereby achieving optimal
