Palmer PEABO is a Balanced Line Output Switch with one input and two outputs. Thus, it is the perfect choice for routing a signal to either one of two possible inputs. Switch your vocal mic between the FOH and monitor mixing desk to communicate with the monitor mixer or the band on stage. Two different sound configurations: to switch between different effects or sounds on your microphone, e.g. a "telephone effect" or more levels of reverb. Run the outputs of the PEABO into two channels of the mixing desk, that you can configure differently. Now you can freely toggle between them on-stage at any time.
