Four Factorial

4 x 4 passive switching router

This module is a 4 x 4 switching matrix in 4 hp that allows any of the 4 in to be switched between the 4 outs and allows for all 24 combinations of 1 to 1 connections. The module has the controls at one end and the jacks at the other and can be placed in the rack either way in the consideration of control ergonomics.
