TLV320AIC3111 DSP functions

Hi, 

We want to realize over 8 or 9 band filters in the dac path, while according to Table 5-25 on a datasheet, AIC3111 has 6 biquad filters at a muximum in dac processing block. 

1.  Are there any ways to use biquad filters in ADC processing block to achieve 8 or 9 band filter for dac processing?

2. How much gain (+/- dB) can we adjust using biquad filter? (We want to know capability of equlization)

3. Can we set two threshold levels for DRC? (We want to have high and low threshold levels.)

Regards.

    1: This is possible when using a custom process flow using the miniDSP with PurePath Studio
    2: The biquad coefficient resolution is 16-bits. The usable dynamic range of each biquad is approx. 60dB.
    3: PurePath Studio has a DRC component with two threshold levels and up to 3 bands
