Foreword
ThishandbookcoversmaintenancefortheSilentPiano™'sGPS‐SHandUPS‐SHseries releasedinJanuary
2013.
ForthefirsttimeevertheSilentPiano™offerssoundsampledfromtheYamahaCFXfullconcertgrand
pianowithbinauralsamplingsystem,enablingreproductionofnaturalandthree‐dimensionalsound.
Theperformancecanberecordedintwodifferentways.Itcanberecordedeitherdirectlytothebuilt‐in
recorderofapiano,ortoaUSBaudiorecorder,inwhichcasethedatastoredinUSBflashmemoryin
WAVformatcanbeplayedonaPCaswell.WhiletheGrandSilentPiano™requiresleveroperationfor
switchingto"Silent"mode,SHtypeSilentPiano™doesitallviamotoractivationwithasinglepressofa
button.
TheheadphonesthatcomeexclusivelywithSHtypepianosaredesignedinawaythatminimizesthe
strainonusersafterlonghoursofplaying.Thesenewlyemployedheadphonescontributetothe
improvementofsoundqualityaswellastothereductionoffatigueduringperformance.
Operabilityofprogramforservicinghasbeenimprovedasfollows.TheCalibrationmodecanbe
executedbypushingbuttonsonacontrolpanel.Thestateandresultofcalibrationcanbeseenonthe
displayonacontrolpanelaswell.Keysensortest,Hammersensortest,Pedalsensortestare
incorporatedasitemsintheTestmodeprogram.
Sincethishandbookmainlyfocusesoninformationrequiredforserviceandsupport,pleaserefertothe
