Scalability in the ASPEN Matrix
Each8x12mixerboardprovides8physicalinputs,12
physicaloutputsandaccesstotheaudioanddatafrom
the48nalmixesintheASPENbus.Fourvirtual inputs
areprovidedinanysystemcongurationtofeedsignals
fromabuilt-insignalgeneratorforsetup,diagnosticsand
sound masking.
Asmultipleunitsarestacked,thesizeofthematrix
growsaccordingly.Forexample,a16input2RUmixer
modelactuallyhas20inputswhenthevirtualinputsare

crosspoints(20x48).Asmoreinputsareadded,thesize
ofthematrixcontinuestoincreasewithoutlimitation.

Signal Propagation in the ASPEN Bus
TheASPENbusprovidesa1Gbpsthroughputcarrying
audioanddatawithasingleCAT6connectionbetween
the units in a system.
Whenmultipleunitsare
stacked, Master and Slave
units are automatically de-
tected and configured for the
correctsignalow.
Audio and data signals
propagatethroughsubmixes.
The lowermost slave in the
system generates a sub-
mixofsignalsfromdevices
connectedtoitandpasses
thesubmixtothenextslave
above it.
Eachintermediateslaveunit
addstothesubmixfrom
theunitbelowit,updates
thesubmixandpassesit
on to the unit above it. The
processcontinuesthrough
all slave units in the system
with no limitation on the total
number of slave units that
can be used.
The Master unit gathers the
submixfromtheslavebelow
it,updatesitwithitsown
signals and generates the
nalmix.Thenalmixis
thenbackpropagatedtoall
slave units below it to enable
systemwideautomixingand
control.
Theaudiooutputofallunits
in the system is taken from
the48channelnalmix.
Thisuniquearchitectureallowsasinglecomputeror
network connection to the Master to have access to all
units in the stack.
