Abstract: A powered speaker system comprising a cabinet and an input to receive an audio signal from an external amplifier. An audio splitter receives and splits the audio signal into first and second portions. At least one first speaker driver receives the first portion of the split audio signal, and an effects output jack receives the second portion. An effects input jack that is connectable to the external effects device, receives the second portion of signal that is modified by the external effects device. An internal amplifier is coupled to the effects input jack and receives and amplifies the modified second portion of the signal. At least one second speaker driver receives from the internal amplifier, the amplified modified second portion. The first speaker driver outputs the first portion simultaneously while the second speaker driver outputs the amplified modified second portion of the split audio signal.
