6.4.2

De-emphasis

Setting the DEMP bit enables de-emphasis on all channels

6.4.3

DSP bypass

Setting the DSPB bit bypasses the EQ functionality of the STA335BWS.

6.4.4

Post-scale link

Post-scale functionality can be used for power-supply error correction. For multi-channel

applications running off the same power-supply, the post-scale values can be linked to the

value of channel 1 for ease of use and update the values faster.

6.4.5

Biquad coefficient link

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.
