Atlanta, GA (November 6, 2009)–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.
The signals encoded by the XDEE module can be routed, and 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. The inputs feature delay and gain controls for 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.
“Dolby E is the de-facto standard for compressed audio with demanding TV productions, in particular, HD,” says Rusty Waite, president of Salzbrenner Stagetec Mediagroup USA. “We are proud to be the first pro audio manufacturer to offer a routing system integrating full decoding and encoding capabilities, thus ensuring maximum signal control and delay-free Dolby E handling. The XDEE is of particularly significance in large HD-enabled OB trucks and, of course, in TV production studios and central control rooms (i.e., everywhere where surround broadcasting has become standard).”
