C.A.B. and attenuator/load output?

Can the C.A.B. be used with the line output from an attenuator/load box like a Weber Mass, Rock Crusher, or Hot Plate? I already have a Hot Plate and don't need the load of the Live, so wondering if I can use the C.A.B. with the Hot Plate instead.

Yes, the CAB will accept either Line Level or Gtr Level I/O.
