Thehigh‐qualitysoundrealised bytheexceptionalS/Nratio
andhighrotationaccuracyofthedirectdrivesystem
employedinTechnicsturntableproductshascaptivatedthe
heartsofaudiophilestheworldover.TheSL‐1500Cinherits
thesamehigh‐qualitysoundfoundinTechnics’high‐end
turntablemodels.Itusesasingle‐rotor,corelessdirectdrive
motorinwhichthestatorhasnocoreandeliminatesthe
rotationirregularitycalledcogging.Inthismotor,the
magneticforceoftherotormagnetswasimprovedtothe
highestpossiblelevel,andthegapbetweenthecoreless
statorandrotormagnetswasoptimised,thusachievinghigh
torqueperformanceequalling thatoftheSL‐1200MK5while
eliminatingcogging.Furthermore,themotorcontrolwas
optimised inaccordancewiththeplatterweight.Asaresult,
theSL‐1500Chasrealised highrotationaccuracyandhigh
performance,andeliminatedtheneedforpartsreplacement
andmaintenance.Anotheradvantageofthedirectdrive
systemisitslong‐lasting,highreliability.

Coreless Direct Drive Motor

Inthedirectdrivesystem,themotorisconnecteddirectlytotheplattersothatthe
motorrotationspeedbecomestherotationspeedofthephonorecord.Therefore,itis
extremelyimportanttocontrolthedrivemotor’srotationspeedtoensurestability.
TheSL‐1500Cutilises thelatestmotorcontroltechnologyrefinedthroughthe
developmentofBlu‐raydiscproducts.Furthermore,theFGcoilpatternofthefull‐
circumferencedetectionFGsystemwasimprovedinprecisiontoachievemore
detailedmeasurementofplatterrotationspeed.

sinewavegeneratedbytheexternalcoilusedintheSL‐1200MK5,thusensuring
accuratemotorcontrol.TheSL‐1500Calsoutilisesthenewestmotorcontrol

incorporatestechnologiesusedinhigh‐endmodelstocorrectvariationsof

Theplatteronwhichavinylrecordisplacedfeaturesatwo‐layerstructurewithdeadeningrubberontheentirebacksurfaceto
eliminateunwantedresonanceinthealuminium die‐castplatter.Theplatteroffershighrigidityandoutstandingvibration‐
dampingcharacteristicstopreventharmfulvibrationfrombeingtransmittedtotherecordanddeliversclearsound.
Toincreasetheinertialmassandminimise vibration,theshapeofthealuminium die‐castsectionwasoptimised through
simulation.Forextrarigidity,reinforcingribswereaddedtothebackside.Theincreasedareaofcontactwiththedeadening
rubbercontributestotheoutstandingvibration‐dampingcharacteristicthatismorethantwotimeshigherthanthatoftheSL‐

EquippedwithanAutoLifterFunctionThatAllowsYoutoEnjoyPlayingRecordsMoreComfortably
Whenthetonearmreachestheendoftherecord,theAutoLifterfunctionautomaticallyraisesthecartridge.Thisprevents
unnecessarywearonyourvaluablevinylrecordsandstylus.ByembeddingtheAutoLifterfunctioninthebaseportionofthe
tonearm,iteliminatesimpactstothetonearm.Duetoasimpledesignthatdoesn’tusemotorpower,thereisnoelectricalor
vibrationalimpactanditwillnotpreventthemovementofthetonearm.Inresponsetorequestsfrommanyusersregarding
theAutoLifterfunction,adesignthatprioritizessoundqualitywasadopted.Thefunctionsrequiredtoplaybackrecords
werekepttoabareminimum,achievingsimpleandeasy‐to‐useoperability.
