QRSispleasedthatyouhavechosentheQRSPNOmaonII™RetrofitKit,thesuperbretrofitkit
forautomangacouscpianos.Thisproductbringsalevelofexcellenceinreproducinglive
performancesonthepiano.Itismadepossiblebymanyremarkabletechnicalinnovaons.
However,inspiteofitshighlevelofsophiscaon,thisretrofitkitiseasytoinstallandservice.

Beforebeginningtheinstallaon,takemetoread“MakeCertaintheKitFits,”toensurethat
thepianowillindeedacceptthekit.This kit will NOT fit into a spinet piano. Familiarizeyour‐
selfwiththepartsinthekitbeforeproceedingandthenlettheinstruconsguideyou.

Allpianokeyshaveatendencytoreactdifferently.Thekeysolenoidsprovidethreeadjust‐
ments:thefirstadjuststheamountofplungerthrowtomatchthatofthekey‐tailli,thesec‐
ondsetsthelostmoonbetweenthekeytailandtheplungerpandthethirdadjuststhe
forceofeachkeysolenoid.

Althoughthekithasbeenprovidedwithenoughsolenoidstoplay80notes,theinstrument
hasbeendesignedtosupporttheenre88‐noterangeofthemodernpiano.Theaddional
partsrequiredmaybepurchasedseparatelyifan88‐noteinstallaonisdesired.

ThestandardPianomaonkitcomeswithapedalsolenoidbutwillalsoruninmagicpedal
modeifthePedalSolenoidisnotpresent.Thepedalsolenoidisconnectedtothepowersupply
bya4posionplug.ThePedalSolenoidwillacvatethetrapwork,thereforeliingthedamp‐
ersoffofthestringsasarealpianistwould.In“MagicPedalMode”thekeysolenoidscontrol
thesustaineventsbyextendingnoteduraonstothecorrespondingpedalONevent.

Theinstrumentusesrelavelylowvoltagessuppliedbyanisolaontransformer.Lowvoltages
eliminatethedangerofelectricalshocktotheinstaller(BelowULlimitof41V).Theelectronics
arefullyshieldedtopreventelectromagnecinterference.

Youwillneedsomematerialsnotprovidedwiththekittocompletetheinstallaon.

Piano Acon Regulaon
Thisdiscussionisnotintendedtobeacompletecourseongrandaconregulaon,butrathermayprovehelpfulinrestoringtheacontoproperperformance.Proper
alignmentofaconparts,andkeyeasingareallveryimportantstepsintheregulaonprocedure.Thefollowingprocedureassumesthatthispreliminaryworkhasbeen
checkedandperformedasnecessary.Beforeremovingtheaconfromtheaconcavity,evaluateaconregulaon.Iftheaconisnotwellregulated,properperfor‐
manceofthesystemcannotbeexpected.

DuringtheinstallaonprocessofthePNOmaonIIPlayerSystem,itisquitepossiblethataconregulaonwillbedirectlyaffected.Aporonofthekeyframeandback
railclothwillberemovedsothatthenotesolenoidplungerscancontactthekeytails.Thisoperaonmaycausethekeytailstobelowerthantheiroriginalposion.The
resultoflowerkeytailsisanincreaseinbothkeyheight,andhammerstrikedistance.Restoringthestrikedistancetospecificaonsbyturningoutthecapstanscrewsis
nottheproperremedy.Alwaysre‐workthebackrailheightsothatthekeyheightisatitsoriginalposion.

‐Arethekeyslevel?
‐Dothehammersletoff1/8inthebass,taperingto1/16inthehightreble?
‐Isthedrop1/16belowthepointoflet‐off?
‐Isthehammerlinestraight?
‐Arethehammershanksapproximatelyoneshankthicknessabovethehammerrestrail?
‐Isthereadequateaer‐touch?

Withtheacononaflat,cleanworkbench,measureandrecordthefollowing:
Naturalkeyheightatbassandtrebleends.
Sharpheightabovenaturals.
Keydip;bothnaturalsandsharps.
Theheightofthefirstandlasthammersineachseconoftheacon.

Replacethekeysandaconstackontheaconframe.Refertotheregulaonmeasurementsrecordedearliertoseeifregulaonhasbeenaffectedbythemodificaons
totheaconframe.Ifkeyheight,keylevel,orstrikedistancearedifferentthanpreviouslyrecorded,stepsmustbetakentorestoreproperregulaon.

Torestorekeyheight,replacethebackrailclothwithoneofathickerdimension.Removetheaconstackandkeys.Aerremovingtheoldbackrailcloth,besurethat
alltracesofgluehavebeenremovedfromthebackrail.Replaceafewoftheendkeysandtryvariousthicknessofbackrailcloth,withoutglue,toballparkthecorrect
keyheight.Lightfingerpressureonthecapstanscrewwillapproximatetheforcethatisnormallyonthecapstan.Setkeyheightwiththebackrailclothat,orslightly
belowthedesiredkeyheight.

Whenyouaresasfiedthatyouhavethebestchoiceofbackrailcloth,gluethematerialtothebackrail,leavingtherearedgeunglued.Nameboardfeltisavailableina
fewdifferentthicknesses,andcanbeusedforfineadjustmentswhengluedunderthebackrailcloth.

Althoughkeyheightcanbereestablishedquiteaccuratelyusingtheaboveprocedure,somekeylevelingistobeexpectedwhenreplacingbackrailcloth.

Rememberthatsubsequentaconregulaonadjustmentswillaffectthosealreadyperformed.Topreparetheaconforfineregulaon,dothefollowingquickly:

Checkorsetrepeonleverheightsoitisslightlyhigherthanthejack.Duringyourfinalregulaon,tripthejacktenderwithyourfingerandreleaseitslowly.Ifregulat‐
edproperly,youwillbeabletofeelthejackbrushingtheknuckleasitisreleased.Thejackmustreturncompletelyundertheknuckle.

ThisseconoutlinesthedifferencesbetweentheinstallaonoftheQRSPNOmaonIIretrofitkitinagrandpianover‐
susanuprightorvercalpiano.Thedifferencesarerelavelysmall,andaninstallerfamiliarwiththeprocedurefor
installaoninagrandpianoshouldhavenodifficultycomplengthistypeofinstallaon.

Thedifferencesareasfollows:
1.Inavercalpiano,theenremechanismishiddenfromviewwithinthecabinetryofthepianoitself,andconse‐
quentlytheinstallercanplacethecomponentsanywhereitmakessensetodoso.

2.Sincethemechanismishiddenfromview,nosolenoidrailcoverisrequired.

3.Thetrapworkisverydifferentfromthatofagrandpiano,andrequirestheinstallertouseaspecialpedalsolenoid
bracketmadespecificallyfortheupright.Thisisaspecialorderitem!

4.Inavercalpiano,theenrekitisinstalledbelowthekeybed.Inmostcases,thebackrailandbackrailcloth
shouldberelocatedtowardthebackedgeofthepianokeys.IMPORTANT********caremustbetakentofirstmeasure
thekeydipatthebackendofthekeysbeforeanyworkbegins.Secondly,aerthebackrailhasbeenrelocated,you
mustensurethatthekeydipisexactlythesameasitwasbeforestarng.Ifitisnot,youmusteithertrimthebackrail
orshimituptoitsoriginalmeasurement.

5.Specialuprightdriverboardmounngbracketsarerequiredformounngthedriverboardstothesolenoidrail.
Thesebracketsare3”longandwillallowthedriverboardandchassistohangbelowthesolenoidrailwhencompleted.

6.SPECIALNOTE****Ifthedriverboardsaremountedupsidedown,youcanreversetheplayingorderofthenotesby
selecng“InvertKeybed”inthe“PlaybackParameters”seconofPMII.

7.Thepowersupplyandtheprocessorboardaremountedinsidethecabinetofthepianoinanyplaceconvenientto
theinstaller.Makesuretheelectricalcablesdonotinterferewithanyofthemechanicalleverswithinthepiano.

8.Itisnecessarytocuta1”holedirectlythroughthesoundboardofthepianotowardstheboomofthepianoatthe
endwherethepowersupplyismounted.Thiswillallowthemainpowerplugtoeasilybepluggedintoawalloutlet.
Thisholewillnotaffectthesoundofthepianoinanyway.

9.Alignmentofthesolenoidrailismadebylayingawoodensckatthetopbackedgeofthekeysandcarefullytrans‐
ferringthecenterlineofeachkeyontothewoodensck.Thissckwillbecomeyouralignmentsck,andthesemarks

Preparing the Key Solenoid Rail
Inthischapter,wedeterminethethrowofthekeysolenoidplungerinrelaontothepianoacon’skey‐tailtravel.
Wealsowalkthroughtheprocessofkeysolenoidalignmentwithrespecttothepianoaconskeytails.Whenthis
chapter’sworkhasbeendone,thesolenoidrailwillhavetheproperrailheightandplungerthrow.Themounng
bracketswillbeinplaceandreadyformounngtothepiano.
