INTRODUCTION
Inspiring the joy of listening
TechnicalAudioDevicesLaboratories,Inc.(TADL)grewfromthespirittodiscovertechnologiestoperfectlyrecreatethepure
soundofliveperformanceswithuncompromisingcraftsmanship.WehaveinheritedourphilosophyfromBartLocanthi—
recognizedacrosstheglobeastheultimatesoundtechnologist—whobelievedthatgenuinetechnologyistruetothebasics
andthatgenuinetechnologyplacesgreaterimportanceonsoundqualitythanontechnologyforitsownsake.
AtTADL,wearehoningourtechnologytocreateequipmentthatreproducesmusicalsoundsthatevokeboththeenergyand
impactoflivemusic.
Main Features
Duallogic-Circuit Technology
Inordertoaccuratelytransmitaudiosignals,itisimportantthatthedynamiccharacteristicsofthetransmissioncircuitrybe
preciselymatchedtothepolarityofthesignals,andremainunaffectedbyexternalnoiseandchangesingroundpotential.
Forthisreason,fullybalancedcircuitryhasbeenadoptedinordertoassureaccuratetransmissionofsignalswiththecorrect
polarity.
Further,theuniformityofrightandleftchannelsiscrucialtoastereoamplifier.Topreservethatuniformity,identicalPCB
unitshavebeendesignedintoeachchannel,togetherwithidenticallengthsofwiringandidenticalstyling,aimingtoachieve
theidealineveryway.
Damping Technology
Themassivealuminumchassis,33mmthickand15kginweight,notonlyresistsexternalvibrationproducedbyspeakers,but
electricallyproducesalowandstablegroundpotential.
Inaddition,thespikeinsulatorsreleasestressesreceivedbythechassisfromthemountingsurface,whilethethree-point
suspensioninsulatorseliminateinstabilityproducedbyunevenmountingsurfaces.
Low-noise design
Inordertoeliminateeffectsfrompowertransformervibrationandmagneticfluxleakage,theTAD-C700featuresadual-case
designtoseparatelyhousethemainelectronicsandpowersections.Housingthepowersectioninaseparatestructurehas
madeitpossibletointroduceasuper-powerful400VA-classaudiopowertransformer,thusallowingtheaccuratereproduction
ofeveryaspectoftheoriginalaudiosignals.
Withitsfull-balanceddesign,theTAD-C700’sDuallogic-CircuitTechnology,togetherwithdirect-currentpanelcontrols,LED
indicators,andlights,allcontributetowardapproachingtheultimateinhigh-fidelityandlownoise.
Simple design for high-fidelity signal transmission
TADbelievesthatasimplesignalpathisthebestmeansofproducingaccurateaudiosignalswithhighfidelity.
SignalsinputtotheTAD-C700arefirstprocessedforsignalvolumebytheelectronicvolumecontrol,afterwhichtheyare
routedthroughanoutputstagecircuitusing1ststagecurrentfeedbackvoltageamplification.Withthissimpledesign,the
INPUTSELECTORremainsastheonlyswitchconnectedseriallywiththesignalline.
TheelectronicvolumecontrolsfeatureTAD-developedladderresistor-switchingdevices,boastingofATTcharacteristicswith
ultra-highaccuracyandextremelylowdistortion(with0.0005%orless/1Vrmsinputs).Thisalsoproducesthecharacteristic
lowimpedanceshiftintheinput/outputconnections,andreducessounddeteriorationwhenthevolumeissettolowlevels.
Newlydevelopedelectronicvolumecontrolsareinstalledindependentlyonleftandrightchannels,thushelpingrealize
uniformitybetweenleftandrightchannels,whileproducingaccuratesoundlocalizationandacousticpresence.Inaddition,
thesecondarystageaftertheelectronicvolumecontrolsfeaturesdualindependentcircuitry,thusresistingdegradationof
soundqualityduetooutputsignalswitchingorbranching,andeliminatinginterferencebetweensecondary-stagedevices.
High-purity power supply circuitry
Thepowertransformer'sinternalcoilismeticulouslyroutedtominimizecontactpointswiththeleadwires,therebyprioritizing
theattainmentofheightenedpurity.Moreover,non-magneticplatingandOFCpurecopperareemployedforthedirectwire
terminals,board-mountedterminals,andfasteningscrews,meticulouslyeradicatinganypotentialformagneticdistortion.
