Four sets of multichannel A/B input switchers are provided to allow rapid switching between two sets of inputs, accessed from a dedicated page in the Tools menu (Menu > Tools > Signal Switcher). Routing to and from the Signal Switchers is achieved through the Routing page. Each signal switcher supports 1 to 64 channels of audio. It is ideally suited for switching between main and backup playback machines, however switchers can be freely routed so can be applied to many different applications.
The switches can be triggered manually from the GUI, via the (e.g. triggered from GPIs, path mutes, DAW Control functions etc.) or assigned to . The currently active set of inputs is indicated by the switch graphic in the Signal Switcher interface.
Additionally, the in the FX Rack can provide automatic switching when a reference signal falls below a particular level. The auto detect switch is swap to B only, and happens when the signal falls below the set threshold. Once triggered, the user must manually switch back to input A if required. This feature prevents the switcher toggling backwards and forwards if the control signal is continually crossing the set threshold. It is advised that a dedicated control signal be provided from the primary audio source to manage this switching, rather than relying on content not having periods of silence.Note: The Signal Switcher is not for use with Mic inputs that require control from input channels. Control data will NOT be passed across the switcher.
