The lattice splitting pad may be used to combine two audio sources into a single audio output or to derive two separate outputs from a single audio source. A characteristic of the lattice pad that makes it very desirable for audio work is the port to port isolation. When used as a splitter, output port to output port isolation is theoretically infinite if the pad resistor values match the input port source impedance. In combiner applications, input port to input port isolation is also theoretically infinite if the pad resistor values match the output port load impedance.
