INTRODUCTION
1.-INTRODUCTION
ARK-70 seriesoffers theuser aperfect tool for processing, with four processor models
available with two or four inputs andeight outputs(analogor digital andEthersoundsystem optional).
ARK-70 seriesprocessorsoffer Double Dynamic, with a RMS compressor/limiterandPEAK
limiter. RMSlimiter is used toadjust thesound level of the transducer, keeping theoriginal dynamics
while respecting the original transition, getting a better acoustic result. Peak limiter controls the
maximum movementof thespeaker, andprotectingagainstdamagewhile reducingthe distortion
causedby anover-excursion. ThisDouble Dynamics minimizesdistortionlevelsandprovides
protection for all acoustic and electronic components of the system.
With fixed latency of 0.6 msARK processorsoffer one of the lower latencieson the market.All
ARKmodelsoffer 120 dB dynamicrange andAD-DAconverter CirrusLogic high-performance24-bit
and 96 KHz. Theinternal DSP processor workswith double precision floatingpoint, reaching a56-bit
internal resolution, oneof the highest resolutionsavailabletodayonthe market. This allowsthe useof
high-precisionfilterswith verylowdistortionandprovidinga quality andunsurpassed soundclarity.
ARK-70processorsoffer an atmospheric compensation function, essential whenworking
outdoors, wheretemperature andhumidity can vary considerably between day and night causinga
majorlossathigh frequencies, especially over long distances. Eachoutput canbeconfigured
separatelydependingonthethrowrequiredforeachbox.
In the security section, different levelsof accessrestrictionsareincluded. That canbe
managed by aglobal password and a presetpassword, with the choice to select which processing
functions can be modified ornot. The front panel canalsobe blocked, denyingany access.
For theavailableARKcontrol software,werecommend readingthe softwaremanual.The
control softwareforARK processor isdesignedto provide the user with a fast and intuitive accessto
eachprocessarea, facilitatingtheprogrammingof the processorfroma computer. Thesoftware
manual isa documentavailablein thedownloadssectionof thewebsite www.vmb.es

console and in the outputs to adjust the level supplied to each amplifier and to equalize the
sensitivity in each way.

DELAY: Configurabledelay. IntheinputsA-Bupto 211 msec. for coveringadistanceupto73m.
For the inputs C-Dup to 54 msec,for covering a distance upto 18 m It ismainly useful
whenworking withimportant PAequipment coveringa largedistance withreinforcementblocs

Thanksto that function, it is possible to rectify the cabinet’s position (alignment) in a multi-way
equipment andavoid cancellingproblemsduetophasecancellationeffects.
PEQ: Output equalisation. There are 9filters completely configurable per output. These filters
can be parametric,6dB/oct. and12dB/oct. lowfrequenciesShelving(with or withoutQ),6dB/oct.
and 12dB/oct. high frequency Shelving (with or without Q), 12 dB/oct. highpass and lowpass,

OPERATING INSTRUCTIONS
4.-OPERATINGINSTRUCTIONS.
Howtoproceed.-
a.- Before switching onthe processor:
ARK includesa precise switching power supply. That means that it can adapt itself to any input
supplyvoltagefrom84and264voltsandfrequenciesfrom50to400Hz.Thisisthereasonwhytheprocessor
isguaranteedtoworkperfectlyunderanyvoltageandthefinalsoundqualityiscompletelyindependentof
the supply voltage or the kind of generator used. Nevertheless it is recommended to check the supply
voltagebeforeworkingtoavoidanypossibleproblemwhenconnectingat380volts.Afuseholderisincluded
in the ARK processor with a spare fuse (1 A) situated in the IEC connector input of the power supply
connector.
Itisrecommendedtoturnoffthevolumeofallthepoweramplifiersdownto0beforeswitchingon
theprocessor.Wewillthenbeabletocheckwhetheranyofthe4processoroutputsareconnectedtotheir
corresponding power cabinets, avoiding any irretrievable damage in the loudspeakers (specially in
expensivehighfrequenciesdrivers).
In anyinstallation, it is suitableto place audio andlighting systemsin independentpower linesto
protectbothpartsseparatelyandtoavoidinterferencesbetweenthedifferentequipments.
b.– Once the processor is ON:
When switchingon the ARK processor, audio outputsremain short-circuited to ground for a few
secondsin orderto avoid thedangerousstart uptransient timenecessary for theprocessorto receivea
