What is the input impedance of the Classe DR-9 amp

The crossovers on my new Vandersteen Quatros have to be set up to match the driving amp's input impedance. Unfortunately, the owner's manual that came with my Classe DR-9 doesn't give the input impedance. Does anyone know the value?

I believe it is 100K ohms.I had these in a bi-amp situation with various crossovers.

The input impedance that I supplied was for the RCA/unbalanced inputs.
