does ADAU1781 support two equalizers?
The ADAU1781 supports two audio inputs and has two audio outputs, with an equalizer in the middle. Can the equalizer be different for the two channels?

Yes. It's important to note that the ADAU1781 doesn't just do equalization. It is fully programmable in our SigmaStudio drag-and-drop graphical programming software. It supports about 400 audio processing algorithms (including various varieties of EQ) that can be placed anywhere in the signal processing chain, independently for each audio channel.
