The
Xpander card is a miniature ethernet and MADI I/O
subsystem which complements the Xrange products including
the Xengine and Xdubber. The Xpander card fits into
a PCI form-factor, eliminating the need for a chassis or
power supply. The Xpander card may be operated in 2
different modes:
 |
Standalone
MADI mode: In this mode, a 64
channel MADI stream and Video Sync reference are
converted directly to Gigabit ethernet. The
audio stream may be directly processed by the
Xengine or Xdubber. This mode gives an
Xdubber or Xengine direct MADI I/O capability.
The daughter card provides additional connectors
for wordclock, tri-level video sync reference, and
MADI I/O. |
 |
Gigabit
Split mode: In this mode, a portion
of an incoming Gigabit audio stream is diverted to
the host Xengine or Xdubber, while the remaining
channels are forwarded via the "thru"
port to the next device. Internal switches
allow the Xpander to divert 64, 128, or 192
channels to the host computer, while forwarding
the remainder to the next device. The
daughter card is not used in this mode. This
mode allows multiple Xengines and/or Xdubbers to
be connected to a single Gigabit port of the
Xrouter. In many cases this eliminates the need
for a second or third router in a large console. |
The
Xpander is fully 64-bit compatible when paired with an
Xrouter or Xengine. The Xpander card uses the
computer's internal power connector but does not connect
to the PCI bus slot. Audio is passed to the host
machine using Harrison's proprietary 64-bit
audio-over-ethernet protocol.
