Esto es lo que dice el manual:
.InputsEach channel of the VS 250 has two parallel inputs. The LINE OUTS of a guitar preamp (oreffect unit) are to be connected here, one to each channel. The purpose of the parallel inputsis. to allow for input bridging. You could, for example, connect a cable from the second,parallel input jack of one channel to another power amp; or from Channel A of the VS 250 toits own Channel B, thereby using the VS 250 as a 2x50-watt mono power amp.
Un saludo.
