I want to use for echo cancelation adaptive filter. I suppose, a block advanced mixer form advanced DSP section it is something that is necessary. Correct? But I can't undarstand from discription how to use it correct? There are two signals. Direct signal to a speacker and signal from mic (echo + real voice). In wich pins of the advanced mixer I should connect each of them signals? Wich remote block should I connect to orange pin? Or should use another blocks for echo cancalation?
