The EZbus mix engine architecture provides eight primary channels, each of which offers EQ and dynamics processing. The eight channels can be fed from any hardware input, analog or digital. A channel's signal can be routed to multiple destinations, including the Main Mix bus, the Alt Mix bus, and any or all of the four Sends; these, in turn, can be routed to a variety of hardware outputs. The EZbus also has four Return busses, which can function as additional input channels. This provides you with a total of 12 input channels, eight of which support EQ and dynamics processing.
