ABSTRACT:
Disclosed is a cross point mixer including a cross point switch and a mixing circuit provided on the output side. The cross point switch includes n.times.m switches arranged in a matrix manner. Each of the switches corresponds to one of a plurality of n input terminals receiving signals, and corresponds to one of a plurality of m output terminals outputting signals. When on, each of the switches forms a signal transmission path which connects a corresponding input terminal with a corresponding output terminal. The mixing circuit provided on the output side receives signals from the n switches correspondingly associated with the output terminal, and subjects the signals to mixing for output to the output terminal.
