Welcome to E2E, thanks for your interest in our products!.
I am not familiar with PurePath wireless commander interface, but from the codec point of view, it is possible to capture audio from a mic connected to the Input Jack as long as the codec enables Micbias to power On the mic. For this, you need to configure the codec's internal registers to power micbias ON and set the input PGA gain to adjust the mic signal to a proper level.
