    This equipment has been specifically designed for the elimination of possible audio feedback that can be generated in an audio system in environments such as churches and conference rooms. Feedback can occurs when a signal comes back to the microphone, after being picked up by a microphone and then played amplified (through the speakers). The signal, due the loop that has been generated, is continually amplified causing a very annoying hiss. The FSHIFTER thanks to the internal DSP shifts in frequency the output signal from the input so that the loop noise does not close ever, going to greatly reduce the possibility of having the annoying hissing.<\/p>\n
