Safetyfirst
Itisimportantthatloudspeakersystemsareusedinasafemanner.Pleasetakesometimetoreviewthefollowingpoints
concerningsafeuseofTHSeriesloudspeakers.
Professionalloudspeakersarecapableofproducingextremelyhighsoundlevelsandshouldbeusedwithcare.Hearinglossis
cumulativeandcanresultfromlevelsabove90dBifpeopleareexposedforalongperiod.Neverstandclosetoloudspeakers
drivenathighlevel.
Stacking
Ensurethatthefloororstageislevelandsolid
Donotstackspeakerstoohighoutdoorswherewindscouldtopplethestack
Beawarethatspeakersproducingveryhighpowerlevelscanmoveorcreep.Toavoidthis,placefrictionmaterial
betweenthefloorandspeakerandbetweeneachspeakerorusestrappingtosecurethestack.
Riggingandsuspension
WARNING:Suspendingthesystemshouldonlybedonebyqualifiedpersonnelfollowingsaferiggingpractices.Securefixingsto
thebuildingstructurearevital.Seekhelpfromarchitects,structuralengineersorotherspecialistsifinanydoubt.
THSeriesenclosuresaredesignedforportableapplications,butcanbesuspendedsinglybymeansofthethreadedinserts
provided.Enclosuresarefittedinternallywithsteelcornerreinforcementbrackets,wherenecessary,toensurethateachcabinet
isstrongenoughtobehungfromitstop.
Neversuspendoneenclosurefromanothertoformanarrayorclusterusingthesefittings
Thecommonpracticeofusingcommerciallyavailableeyeboltsforsuspensionshouldonlybeundertakenwithgreat
caution.
Onlyforgedormachinedshouldereyeboltsshouldbeconsideredanditisimportantthatthethreadlengthisatleast
30mm
Formedeyeboltsi.e.thosewhichareformedfromasteelrodbentintoaneyearenotrecommended
Eyeboltsarestrongestalongthethreadaxis.Anglingtheenclosurewillresultinananglepullanditisimportanttouse
eyeboltsthataresafeinthesecircumstances.

Amplification
Choosingapoweramplifier
MartinAudioloudspeakersarecapableofrecreatingmusicaldynamicsaccuratelyandwithincredibleimpactifpowered
correctly.MartinAudioloudspeakerpowerratingsarequotedforAESpower‐along‐termaveragepowerratingwithamuch
closerrelationtoamusicsignalthanothermeasurementstandardssuchasRMS,andPeakpower–ashort‐termburstcapability.
MovingcoilloudspeakerscanberunuptotheirAESpowerratingcontinuouslyanduptothehigherPeakpowerratingfor
transientmusicalpeaks.AllTHSeriesspeakershaveapeakpowerratingfourtimesthelong‐termAESrating.Ideallyyoushould
useanamplifierthatcandeliverthefullpeakratingwithoutriskofclipping.Thishowevermaybebeyondthebudgetformany
soagoodcompromiseistoaimforanamplifierthatcandeliveratleasttwicetheAESrating.
Thisshouldbeacceptableformanyapplicationsbutbeawareofthelimitationsparticularlyifthesystemisusedwith
uncompressedlivemusic.Inparticularitisvitaltoavoidamplifierclipping,thisispossiblythebiggestsinglecauseofdamageto
speakerdrivers.Theclippedwaveformhasacolossalharmonicoutputatultra‐highfrequenciesallbeingdeliveredatthefull
powercapabilityoftheamplifiersospeakerdamageisextremelylikely.
Theamplifierselectiontablebelowwillassistinchoosinganamplifiertosuityourapplicationatanacceptablepricepoint.
GainSettings
Thevastmajorityofprofessionalandevenbudgetamplifiersonthemarketthesedayshaveastandardfronttobackgain
regardlessoftheiroutputpowercapability.Theindustrystandardgainfigureis32dBwhichisagainofX40.Thisfigureisagood
balancebetweenenoughgaintorunthatmajorityofsystemswithouthavingtodrivemixersandanyotherprocessingequipment
atalevelsohighthatthereisariskofclipping,andnottoomuchgainwhichwouldraisethenoisefloorofthesystem.When
usingaDX0.5orothersystemprocessorwhichhasalimiterfunctionyoushouldalwaysusethelimitersettingsshowninthe
parameterchart(seethechapterontheDX0.5SpeakerProcessor).Thelimiterthresholdiscalculatedtoallowthemaximum
levelfromyoursystemwithoutdamageandisbasedonaknownamplifiergainsetting‐32dBbydefault.Forthatreasonitisvital
thatiftheamplifierhasfrontpanelgaincontrolstheyMUSTbesetFULLUP.Loweringthemdoesnotoffermoreprotectionfor
yoursystem,itjustchangesthegainsettingoftheamplifiersoagreaterinputlevelisrequiredtoobtainthemaximumpower
fromtheamp.Thiswillmakethelimiterinthesystemcontrolleruselessasthegainisnolongeratthesettingforwhichthe
thresholdhasbeencalculated.Foroptimumperformancealwaysobservethefollowing;‐
UseaDX0.5,DX1.5,DX2orhighqualityloudspeakerprocessor
UsethepublishedParametersfortheTHrange
Useanamplifierwithagainof32dB(X40)
Alwaysrunfrontpanelgaincontrolsfullup
Avoidamplifiersthatonlyquoteasensitivityrating;"xxdBformaximumoutput"(i.e.nopublishedgainsetting)

WiringDiagrams
ThereareseveralwaysthatTHsystemscanbeconfiguredsowewillnowlookatsomepracticalwiringexamplesforthemost
commonsystemconfigurations.
SystemA‐basicset‐upbi‐ampingTHVorTHH

Thisisthemostsimplesystemsetupforstereooperation,connectingfromyoursource,oftenamixer,straighttoaDX0.5(or
othersystemprocessor)usingbalancedXLR"microphone"cables.FromtheDX0.5wetakefouroutputs,twolowfrequencyand
twohighfrequencyandtheseareroutedtothetwoamplifiers.WethenuseaspeakercablethatcombinestwoNeutrikNL2or
NL4Speakonconnectorsintoasingle4‐corespeakercabletogofromtheamplifieroutputstotheTHspeakerinputs.Thiscould
alsobeachievedwithacustompatchpanelusingNL4panelconnectorswithshortspeakercablesroutedfrompins1+/‐and2+/‐
onthepaneltothehighandlowfrequencyamplifiers.Thiswillallowastandard4‐corespeakercablecanbeusedbetweenthe
panelandTHspeaker.


ThissystemissimilartoSystemArunningastereopairofTHV(orTHH)bi‐amplified.ThistimewehaveusedaniK42amplifier
fromtheIKONrange.Thismakessystemwiringextremelysimple.Firstwecandisregardtheloudspeakerprocessorasthe
amplifierhason‐boardDSPandfactorypresetsareavailableinVu‐Nettoaddthecorrectparameterstoeachchannel.Secondly,
theamplifierhasfourchannelssoonlyasingleampisrequiredtodriveastereopairofTHV(orTHH),inadditiontheoutput
wiringcombinesamplifierchannelsontosingleNL4connectorssooutput2isavailableonbothpins1+/‐onchannel2NL4and
alsoonpins2+/‐onoutputchannel1NL4.Likewise,outputchannel4appearsonchannel4NL4andchannel3NL4onpins2+/.
Thismakesdrivingbi‐ampedcabinetsverysimpleasastandard4‐coreNL4speakercablecanbeusedstraightfromtheamplifier
totheTHV.Nospecialspeakercablesorpatchpanelsarenecessary. 

SystemC‐IntroducingSubs

Thissystemaddsapairofsubwooferstoenhancetheextremesubfrequencyresponseofthesystem.Onthisexamplewehave
usedtheSX218twin18"directradiatingportedsubwoofer.TheMartinAudioDX0.5isagainusedforsystemprocessing,this
timeusingallsixoutputstoprovideleftandrightoutputsforsub,lowandhighfrequencies.ADX1.5orDX2mayalsobeusedor
evenathirdpartyprocessor,parameterstoprogramtheseareavailableinspreadsheetformontheLoudspeakerSettingspage
ontheMartinAudiowebsite.
Aswellasapplyingtherecommendedequalisationtheprocessoraddsalimiterinthefinalstageofprocessingtoprotectthe
systemfrombeingdamagedbybeingover‐driven.
TheXLRfeedsfromthemixergototheinputsoftheDX0.5,theDX0.5outputsshouldbeconnectedtotheamplifierinputswith
shortXLRcables.Aswiththebasicsystem,acablecombinestheoutputsfromtheHFandLFamplifiersintoasinglespeaker
cabletoconnecttotheTHV(orTHH).
Anadditionalamplifierisrequired,thisisalsofedfromtheprocessorandtheoutputsgodirectlytotheSX218withstandardNL4
speakercables.

SystemD‐UsinganIKONiK42andSXH218

ThissystemissimilartotheprevioussysteminthatisusesapairofTHV(orTHH)andapairofsubwoofersbutthistimeusing
theSXH218Hybrid®loaded2x18"subforultimatesubfrequencyreproductionandusesoneoftheMartinAudioIKONiK42
fourchannelamplifierstodrivethelowfrequencyoftheTHVandtheSXH218sforaneatsolutionavoidinghavingtoaddathird
amplifier.Channels1and2drivetheLFoftheTHVandchannel3and4drivetheSXH218.Aseparate,smalleramplifieris
deployedtodrivetheHFwhichdoesn'trequirethesamepowerlevelastheLFandsub.
Aswiththeprevioussystem,thereareleftandrightconnectionsfromthemixertotheinputoftheDX0.5(orDX1.5,DX2).Output
Channels3and6ontheDX0.5connecttoinputsAandBontheamplifierdrivingtheTHVhighfrequencyusingapairofshort
XLRcables.FourmoreXLRcablesconnectfromoutputs1,2,4&5ontheDX0.5totheinputsoftheiK42.
WhilstwehaveusedtheDX0.5thiswouldn'tstrictlyberequiredfortheLFandSubastheiK42hason‐boardDSP.Processing
wouldhoweverberequiredforthefeedtotheamplifierdrivingtheHFunlessthisalsohason‐boardDSP.
SpeakerwiringasbeforeusesacustomcabletocombinetheLFandHFfeedsontoasingle4‐corecable(orapatchpanelcould
