Ifthisequipmentdoescauseharmfulinterferencetoradioortelevisionreception,whichcanbedeterminedbyturningthe
equipmentoffandon,theuserisencouragedtotrytocorrecttheinterferencebyoneormoreofthefollowingmeasures:
Reorientorrelocatethereceivingantenna.
Increasetheseparationbetweentheequipmentandthereceiver.
Connecttheequipmentintoanoutletonacircuitdifferentfromthattowhichthereceiverisconnected.

HowtoUseThisManual
Afterthisintroduction,agettingstartedguidewillhelpyougetthingssetupfast.Thehook‐updiagramsshowsometypical
setups,whiletheremainingsectionsprovidedetailsoftheDX0.5andhowtouseittooptimizeyourloudspeakersystem.
GettingStarted
Thefollowingstepswillhelpyousetupyoursystemquickly.
1. MakeallinitialconnectionswiththepowerswitchesOFFonallequipment.Makesurethemastervolume,level,orgain
controlsareallthewaydown.
2. Connecttheline‐leveloutputsfromyourmixingconsole(orothersignalsource)totheinputsoftheDX0.5Loudspeaker
ManagementSystem
3. Connectoutputs1‐6fromtheDX0.5totheinputsofpoweramplifiersORdirectlytotheinputsofPoweredloudspeakers
and/orsubwooferssuchastheMartinAudioDD12orPSX.
4. Ifusingamplifiers,connecttheoutputsfromthepoweramplifier(s)totheinputsofPassiveloudspeakers.
5. Turnonthemixingconsole(orothersignalsource).
6. TurnontheDX0.5LoudspeakerManagementSystem.


8. Un‐mutetheappropriateoutputsontheDX0.5.[Seepage15fordetails.]
9. Turnontheamplifier(s)ORpoweredloudspeakers.Turnupthevolumeorgaincontrol(s),inmostcircumstancesgain
controlsshouldbeturneduptomaximumsotheamplifiergainmatchesthelevelatwhichlimiterthresholdsinthe
DX0.5havebeenset.
10. Startthesignalsourceandraisethemixer’smainL/Rfader(s)upuntilaudioisheardthroughtheloudspeakers.
Atthispointthesystemistestedandworkinghoweverwestronglyencouragethatyoureadtherestofthisowner’smanualto
learnbasicnavigation,howtoedittheinputsandoutputs,setsecurityfeaturesandmore.
ThingstoRemember:
Neverlistentoloudmusicforprolongedperiods.PleaseseetheSafetyInstructionsonpage6forinformationon
hearingprotection.
Whenyoushutdowntheequipment,turnofftheamplifiersfirsttopreventthumpsandothernoisesgeneratedby
anyupstreamequipmentfromcomingoutofthespeakers.Whenpoweringup,turnontheamplifierslast.
Savetheshippingboxesandpackingmaterials,intheunlikelyeventofaproblemwiththeDX0.5thesemaybe
requiredtoshipthedevicetoanauthorisedServiceAgent.
