The!AMX0.2CN!is!a!CobraNet™!interface!with!2!analog!Line!level!output!channels.!The!
digital!audio!streams!are!sourced!from!the!CobraNet™!interface/CS496112!chipset!and!
converted!into!analog!audio.!The!CobraNet™!interface!provides!8!simultaneous!bundle!
receivers!with!up!to!8!simultaneous!audio!streams!(see!Cirrus!Logic!UM23!and!PM25!
for!full!details!of!the!CobraNet™!chipset!and!protocol).!
!
Each!Bundle!receiver!can!handle!8!audio!streams!of!20bit!word!depth.!Eight!Bundle!
transmitters!would!therefore!imply!a!potential!of!64!audio!streams.!However!the!
chipset!is!limited!to!a!maximum!of!8!simultaneous!incoming!audio!streams.!!Thus!the!8!
streams!can!be!sourced!one!from!each!of!8!Bundle!receivers,!or!all!8!streams!sourced!
from!one!Bundle!receiver,!or!any!combination!in!between.!
!
For!example,!the!2!analog!outputs!could!be!sourced!from!2!different!network!locations,!
ie!2!Bundle!receivers,!each!of!1!audio!channel.!Or!an!8!channel!bundle!of!BGM!audio!
could!be!sourced!from!the!network!and!the!desired!BGM!channel!within!the!8!from!the!
Bundle!receiver!could!be!locally!routed!to!the!analog!output.!
!
The!AMX0.2CN!is!powered!by!IEEE802.3af!Power!over!Ethernet!(PoE).!
!
In!addition!to!audio!transport,!the!CobraNet™!port!provides!control!and!monitoring!
capability!via!SNMP.!MTS!provides!an!OEM!version!of!Stardraw!control!with!embedded!
MTS!SNMP!drivers!for!custom!GUI!rendering.!!This!is!downloadable!from!the!MTS!
website.!
