Abstract: A system for performing signal processing includes a system input, wherein a first signal having a first format, and supplied on a first system input is selected by a user for format conversion. A switching circuit having plural switching circuit inputs and plural switching circuit outputs is provided for routing the first signal, received via a first switching circuit input, to a first switching circuit output. A processor is connected with the switching circuit for converting the first signal received via the first switching circuit output into a second signal having a second format, wherein the second signal is supplied to a second switching circuit input, and output to a first system output via a second switching circuit output.
