dLive is a distributed digital mixing system providing a uniquely flexible solution for any live sound application. It separates the mix engine from the control surface, putting the audio and processing where it is needed, and offering a host of control and audio networking possibilities. Refer to the Allen & Heath website to find out more about dLive. The MixRack is the heart of any dLive system. It houses the XCVI processing core complete with audio I/O, control and audio networking ports. The Surface is effectively a network controller for the MixRack, with the addition of built-in audio I/O and audio networking ports. DX Expanders can be added to the system for extra I/O.
