In SigmaStudio there is a unit Parametric EQ
(Filters -> Second Order -> Double Precision -> Multichannel).
It has the ability to adjust the frequency response for 15 frequencies.
I have 3 chips: ADAU1702, ADAU1451, ADAU1467.
In chip 1702, the Probe unit together with the Parametric EQ unit displays all 15 frequencies
configured in the Paramtric EQ unit.
And in the microcircuits: ADAU1451, ADAU1467 the Probe unit together with the
Parametric EQ unit displays only 1 first frequency set in the Parametric EQ unit.
The remaining 14 frequencies on the frequency response curve in the PROBE unit
are not displayed. And physically all 15 frequencies set in the Parametric EQ unit work
correctly.How can this be correct?
