Stagetec has developed a Dolby E encoder board for its audio routing system, NEXUS, allowing up to eight freely selectable audio channels to be encoded to a Dolby E stream. Not only can the signals encoded by the XDEE module be routed, Dolby E signals from external sources are distributed unaltered (i.e., as encoded Dolby E streams) via the NEXUS.
A special feature enables XDEE to deal with asynchronous signals: all discrete inputs include sample-rate converters. Moreover, the inputs feature delay and gain controls for optimum adjustment of the signal to be encoded. There is also an extra audio path for non-encoded audio, which can be used, for example, to carry an independent stereo signal, or a commentary channel. XDEE locks to bi- or tri-level video syncs and can generate word clock from this to synchronize the entire NEXUS network.
