The XAP 800 has a variety of automixing functions that are implemented on both a
per-channel basis and across the entire automatic mixer. These functions are
described on the following page. Each XAP 800 can have up to four separate
automatic mixers working independently within a single unit, and up to four
independent global mixers across multiple units. In addition, more microphone
channels can be added by linking XAP 800 units via the Expansion Bus, the digital
network bus. Unlike other “expandable” automatic microphone mixers, the XAP 800
works as a single unit for up to eight units networked together, for a total of 64
microphones. Expanded analog automixers can offer only limited functionality such
as NOM (number of open microphones). Multiple XAP 800 units can operate as a
single unit because all functions are implemented digitally and all units are
connected together using the high-speed digital network bus (Expansion Bus),
which passes both audio and control information. See Figure 12.
