VSXNET Subwoofer Operation Manual rev 2.0.0
2. Introduction
Designed,engineeredandbuiltintheUnitedKingdom,theVSXNETSeriesfromTannoycomprisesofone
band-passandtwodirect-radiatingsubwoofersfordemandingprofessionalandcommercialsoundapplications.
WithintheVSXNETSeries,systemdesignerscanchoosefromavarietyofsizes,powerlevelsandlowfrequency
characteristicstosuitparticularrequirements.
Asindicatedbytheirrespectivesufxes,theVSXNET12.2BPisaband-passdevice,whiletheVSXNET15DR
andVSXNET18DRaredirectradiatingmodels.Thethreeband-passmodelincorporatesTannoy’slatest
engineeringphilosphiesinband-passenclosuredesign,optimisingtonalbalanceandharmonicoutputthrough
preciselyengineeredenclosuregeometryandinnovativetransducerdesign.
Foreaseofinstallation,connectionsareonintegrated,recessedterminationpanelsequippedwithboth
NL4speakON®andbarrierstripconnectors.ThespeakONconnectorsareangledandrecessedtoallowush
mountingtoawallorceiling.
AllVSXNETSeriessubwoofersarehousedinrugged,durablebirchplyenclosureswithergonomicIntegrip™
carryhandlesandanintegratedpole-mountrecess.CouplingVSXNETSeriessubwooferstoVXandVXPSeries
full-rangeloudspeakersviatheoptionalVTHpolemountfacilitatesportablePAapplicationswithoutneedfor
tripodstands.
3. Unpacking
EachTannoyVSXNETSeriessubwooferiscarefullytestedandinspectedpriortoshipment.Afterunpacking,
pleasecheckforanyexteriorphysicaldamage,andsavethecartonandanyrelevantpackagingmaterialsin
casetheunitagainrequirespackingandshipping.Intheeventthatdamagehasbeensustainedintransit,notify
yourdealerandtheshippingcarrierimmediately.
4. Preliminary Recommendation
VSXNETSeriessubwooferscanproducehighsustainedoutputlevelsforlongperiodsoftime.Ifusersarein
closeproximity,theselevelscouldleadtopermanenthearingdamage.BecauseTannoyloudspeakers
haveanatural-sounding,atfrequencyresponseandverylowdistortion,usersmaynotbeawareofthepotential
hazard.Forcontinuousexposuretohighlevels,werecommenduseofasoundlevelmetertoensurenoise
levelsarewithinsafetylimits.Themetershouldbecapableofintegratinglevelsoveraperiodofexposurein
conformancewithnoisecontrolstandards.

6. Operation
Therangeofproductsarefullyintegrateddesigns,allspeakermanagementfunctionswhichincludedriver
EQ,dynamiclimiting,&crossoverfunctionsarecarriedoutwithintheDSP,thereforetheneedforexternal
amplication,activecrossoversandlimitersisnotrequired.Theonlyinputfromtheuseriscrossoverbetween
fullrangecabinets&subwoofers,androomequalization(ifnecessary).
Whenroutingaudio,unitsmaybedaisychainedtogetherbylinkingtheInput/linkXLRconnectors.Itis
necessarytohavepowerlocaltoeachspeaker,asitisnotpossibletodaisychaintheACpowerconnectors.
6.1 AC power requirements
VNETproductsareequippedwithNeutrikPowerconTMmainsconnectorswhichmatewiththeNeutrikNAC3FCA
Cableconnector,quicklockwithasecuringleverforpower-in.ThisACmainsconnectorissuppliedwitheach
VNETproduct.Theamplieroperatesbetweentherangesof100to240Volts;theautorangingpowersupply
detectsthemainsvoltageautomaticallyandconguresaccordingly.Replacethemainsfuseonlywiththesame
T10AHBCtypesuppliedbyTannoyunderpartnumber34610919.
6.2 Cooling
Donotinstallthisequipmentinanenclosedspace.Donotlimitfreeventilationandmovementofairaroundthe
backpanel.Ensurethatthereisatleast100mm(4”)ofspacearoundallsidesoftheproductforventilation.An
efcientswitchmodepowersupplyhaslessweight,lesscurrentdrawandmoreefcientmechanicalcooling;
meaningthatnofansarerequired.Inanareawitharelativelyhighambienttemperaturetheheatsinkcanreach
temperaturesofupto65degreesC,thisisperfectlynormal..

6.3 LED functions
OnswitchonalloftheLED’swillilluminateinstantaneously.ThersttogooffisthegreensignalLEDafterabout
1second.TheredlimitLEDwillashfor5-10seconds,thisistheunitperformingaselfdiagnostictest.During
thisinitialfewsecondstheaudioismuteduntiltheredLEDstopsashing&thebluepowerLEDistheonlyLED
leftilluminated.
Aftertheselfdiagnostictestisperformed,theunitisreadytopassaudio.Whenaudioisdetectedthegreen
signalLEDwillilluminate.IfatanytimetheRedLEDashesthisindicatesthattheDSPistakingcorrectiveaction
byapplyinglimitingtoeithertheLForHFchannels(orboth).RegularickeringoftheLimitLEDisperfectly
acceptable;donotallowthelimitLEDtostayonconstantlyforanysustainedlengthoftime(reducethegain).
FastregularashingoftheredLEDindicatesthattheDSPistakingprotectiveaction;theinputwillbeautomatically
attenuatedtoavoidoverdriving,ifthisoccurstheoperatorshouldreducetheinputgainfromthesource.Ifthegain
isnotreducedtheunitwilleventuallybeshutdownbytheDSP.
Theblue‘NetworkFind’LEDonthefrontofthecabinet(behindthegrill)canonlybeilluminatedbyactivation
fromwithinthesoftwareinterface.WhenactivatedtheLEDwillashintenselyasanaidtolocateandidentify
loudspeakersconnectedonthenetwork.TheredlimitLEDonthebackpanelalsodoublesasanetworknd
LEDduplicatingthefunctionofthebluefrontmountedLED.
6.4 Limiters
Thelimitersarecarefullyset-uptopreservetheloudspeakersdynamicheadroombyallowingshorttermtransients
topass;audibledegradationinsoundwillonlybecomeapparentwhenthelimitindicationisonconstantly.The
limitingfunctionswillprotecttheamplierfromlongtermoverheatingbyattenuatingthedrivingvoltagetothedrive
units.Ifusedirresponsibly(constanthardclipping)soundqualitywillbecompromised.Inextremecasesdriveunits
mayalsobedamaged.
6.5 Audio Connections
Thesignalinput&linkconnectorsarefullybalanced. SIGNAL XLR CONNECTOR
Whenconnectingabalancedsignalbesuretowire Hot(+)  Pin2
tothefollowingstandard:- Cold(-)  Pin3
 Shield(GND)  Pin1
Inastandardbalancedinterconnectiontherearetwosignalconductorsandashield.Theshieldisnormally
referencedtogroundatoneorbothends.Manytimestheshieldisliftedatoneend,usuallyattheinputto
eliminate“groundloops”ornoise.Theproblemwiththisapproachisthatwhileitmayreducehum,theshieldsact
asradioantennasandpickupradiofrequencyinterferencefromtheenvironment.
Multipleenclosuresmaybedrivenfromasingleaudiosource;simplyplugthesignalsourceoutputintotherst
XLRinputsocket,andpatchthatspeakersXLRlinktothenextspeakersXLRinputsocket&soon.

6.6 User DSP On/Off
AuserDSPOn/Offswitchisprovidedontheamppanel.Thisminiatureswitchisrecessedandcanbeeasily
activatedwithasmallscrewdriver.
Theswitchinthe‘OFF’positionwillreturntheVNETloudspeakerbacktotheoriginalfactorysettings,thisbasically
meansthatanyparametereditedinsoftware(EQ,Crossover,Mute,Delay)canbedefeatedbyactivatingthis
switch.Thiscanbeaveryusefulfeature.Example:-
Inalargecorporateproductionthenetworkedloudspeakersarebeenusedbyanoperatorwhohasbeenusing
thePodwaresoftwareforeditingEQ&gain&delay;attheendoftheperformancehemutestheloudspeakers
fromwithinthesoftwareandtheloudspeakersarereturnedto‘hirestock’aftertheperformance.Nextdaythere
isarushforasmallhirecomprisingonlyacoupleofVNETloudspeakers.Thespeakersaretakentothesmallgig
wheretheoperatorisnotmakinguseoftheNetworking,orPodwaresoftwareinthisparticularinstance.
Herealizesthathemutedtheloudspeakersthenightbefore,andthisparticularpairhad100msofdelayapplied!!
Allhehastodoisickthe‘USERDSP’switchtothe‘OFF’position(assumingheiscarryinghisLeatherman)and
anyoftheUSEReditableparametersinPodwarearedefeated.

7. Network Connections
Interconnectionbetweenthenetworkcomputerandthespeakersisverystraightforward,usingtwistedpair
cableandsimpleconnectors.TheRS485interfaceoperatesonasharedbussothatasinglecomputercan
controlanyamplieronthebus,andthecomputermaygatherstatusinformationfromanydeviceonthebus.
Eachmodulecontainsauniqueaddresssothatnouserinputwillberequiredtocongurenetworknodes.
Itisonlydatathatiscarriedoverthenetworktocontrolsetupfunctions&ongoingsystemdiagnostics,therefore
ifanetworkfaultoccurs,audiocanstillbedelivered.Thisalleviatestheproblemoftotalsystemfailurethrougha
singlesystemcontrollergoingdown.AseachloudspeakercontrolsitownDSPfunctionsanyunforeseenfailure
wouldbeisolatedtoonlythatparticular‘node’.
RS-485isstandardforsendingserialdata.Itusesapairofwirestosendadifferentialsignaloverdistancesup
to4000feet(1200m)withoutarepeater.Thedifferentialsignalmakesitveryrobust,RS-485isoneofthemost
popularcommunicationsmethodsusedinindustrialapplicationswhereitsnoiseimmunityandlong-distance
capabilityareaperfectt.
IMPORTANT:AlwaysrunasignalgroundwithRS-485

NetworkconnectionsbetweennodesareviaruggedNeutrik‘ethercon’connectors;thesearehighqualityandare
compatiblewithstandardRJ45plugs.NodeconnectionsaremadeusingstandardRJ45connectorsandCAT5
cable.Longrunsshouldbesolidcore,butstandardisne.Theimplicationisthatstrandedismorerobustandless
pronetobreakage,itisthereforesuggestedthatsolidshouldbeusedforinstallapplicationswhilestrandedisbetter
suitedtorentalapplications.Cabinetscanbe’daisychained’orlinkedina‘star’conguration,oracombinationof
