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.
