NETWORK CONSIDERATIONS AND ROUTER CAPACITY
Each core contains a Hydra2 router
card fitted in the Main router slot
which provides a capacity of 8192
audio input channels and 8192 audio
output channels (Apollo, Artemis
Shine/Beam) or 4096 audio input
channels and 4096 audio output
channels (Artemis Light / Summa).
8URouterOverview
The Apollo and Artemis (Shine/Beam)
router (RY5710) is described as an
8192
2
router, which means up to 8192
separate sources can be routed to 8192
destinations. Although the router is
described this way, there can be up to
12288 inputs (6144 inputs for 4U router),
as described later in this section. Hydra2
routers can also be networked together to
scale the available inputs up as required.
Only one source can supply audio to each
destination, but a single source can supply
audio to all destinations, hence it is a ‘1-
n’
router.
4URouterOverview
The Artemis Light and Summa (RY5912)
router is described as a 4096
2
router.
The considerations described above for
RY5710 are also valid for this router but
the maximum number of routes which can
be made is 4096.
8URackConsiderations
For an Apollo/Artemis 8U rack with a
DSP card installed, 2048 destinations
are reserved to pass audio internally, via
the rack backplane, to and from the DSP
mixing engine, leaving 6144 destinations
available for external signals via the router
card’s front panel ports.
ExpansionRouterCards
Expansion router cards can be fitted into
8U processing cores (Apollo, Artemis
Shine/Beam). A router card fitted in the
expansion slot increases connectivity
by doubling the number of front panel
Hydra2 ports available, it does not act
as an independent router or increase the
total capacity. In order for an expansion
router to be fully functional, there must be
a router card fitted in the main router slot
as well.
When an Expander card is fitted into a
rack, 2048 destinations are reserved
for access via the Expander card’s front
panel ports, therefore for a rack with a
DSP and an Expander card fitted, 4096
destinations are available through the
router and 2048 through the expander;
the addition of an expander card, expands
the number of ports for connecting I/O
boxes, not the number of destinations.
2048 sources can be routed from each
DSP or Expander card to destinations on
the router (routes made from sources to
destinations that are on the expander only
donot use this capacity). The number
of sources available increases by 2048
when a DSP or Expander card is fitted:
• neither = 8192 sources
• DSP = 10240 sources
• Expander = 10240 sources
• DSP and Expander = 12288 sources
4URackConsiderations
For an Artemis Light or Summa rack with
a DSP card installed, 2048 destinations
are reserved to pass audio internally, via
the rack backplane, to and from the DSP
mixing engine, leaving 2048 destinations
available for external signals via the router
card’s front panel ports. The Artemis
Light / Summa core does not support
expansion router cards.
The number of sources available
increases by 2048 when a DSP card is
fitted, from 4096 to 6144.
