Default Input impedance of Arjen's amp?

Hi

I've just bought Arjen Helder's MKIII module and want to use it in a biamp setup with a PLLXO.

I need the input impedance to get the design right but don't have the equipment to measure it. I've asked Arjen (no response) so was hoping someone else who owns this amp has bothered measuring and can tell me??

Rob

Hi Rob, it's the value of RI (20K), correct me if I'm wrong.
