AudiBox Series Stereo A or B Switcher, 4-XLR Female Inputs & 2-XLR Male Outputs The simplest ideas are usually the best! The new ISO Switcher is a stereo Input signal switcher for the extremely popular Audibox range. A front panel push button switch silently switches between two pairs of A or B female XLR inputs to a stereo pair of XLR male output connectors. ARX 'SoftSwitch' technology achieves this with no loud noises through the audio system when switching. Typical applications include switching between Live Band or DJ when both are using the same speaker system. The simplest ideas are usually the best!
