The turntableplatter and precisionparts are packedseparate-
ly from the woodenbase inthe samepackingcase.
When you unpack the packingcase,takethem out withcare
so asnotto scratch or breakthem, and assemblethem as
follows:
REMOVING THE TONEARM PACKING
Check and remove the accessoriesstored inthe polystyrol
packing onthe tonearm.Thenremove the packing. Access-
ories storedthere : (Fig. 3)
1. Motorpulley 2.EP recordadaptor 3. Smallscrewdriver
4. Lubricator
5. Weight plate, etc.

CHASSIS SUSPENSION
For protectionduringshipment, the chassis is secured tothe
base with the three red screws.Thesemust be removed before
assembling the turntable. The chassis will then floatonits
vibration-absorbing spring suspension(Fig. 4).
MOUNTING OF TURNTABLE PLATTER
The turntableplatter and rubber matare packedseparately.
Takethemout.First putthe turntable onthe centershaft.
After the drive belt has been setonthe motorpulley,place
the rubber matonthe platter(Fig. 5).
SETTING THE BELT ONTHE MOTOR PULLEY
Set the speedselectorlever tothe33 rpm position.Pulling
the ribbonattached tothe drivebelt,lead the beltthrough
the belt guide andsetitonthe smallerdiameterportion
(theupperportion) ofthe motorpulley. After the belt has
been properly setonthe motorpulley,remove the ribbon
(Fig. 6).
ATTACHING THE DUST COVER
1. Holddustcoververtically(Fig. 7 A).
2. Frombehind,slip cut-outs in coverhingesoverpegs on
base hinges.
3. Pushdustcoverabout 1/3in.tothe right (as seen from
the back) to securehinges(Fig. 7B).

ATTACHING A PHONO CARTRIDGE
The color-coded pin connectors inthe headshellconform to
the international EIA standard.Attach the cartridgeaccord-
ing tothe drawing(Fig. 8).
Then plug the headshellinto the front endofthe tonearm
and tighten it by giving the tonearmsleeveapproximately
one turn.
OVERHANG ADJUSTMENT
For optimumperformance, the cartridge should be adjusted
to obtainproperstylusoverhang.
Place the tonearm onits rest. Loosen thetwo cartridgehold-
ing screws a little, and move the cartridgeback and forth in
the head shell so that the stylus tip comes exactly over the
white line inthe "OVERHANGCHECKER." For easier
checking, this "OVERHANGCHECKER" canbe pulled up
(Fig. 9).
If the cartridge weighslighter than 7 grams,remove the
sub-weight from theendofthe tonearm(Fig.10).
TRACKINGFORCE ADJUSTMENT
HORIZONTAL BALANCING
Remove the stylusguard from the cartridge.Free the
tonearm from its rest, butbe sure to hold it carefully and
notto drop it during the following adjustments.
Move the maincounterweightslowlyback and forth (by turn-
ing it) until the tonearmfloats in horizontalposition.Keep-
ing the weight in thisposition,turnonly the trackingforce
dialring so that the zeroaligns with the backindexline on
the tonearm ( Fig. 11).
APPLYING THE TRACKING FORCE
With the tonearm in floating condition,turn the counter-
weight and align the desirednumber (0to3.5 grams)with
the indexline. Forthe correcttracking force, please refer to
the instructionssuppliedwith the phonocartridge.

LATERAL BALANCE
First loosen the lateralbalanceweight-securedscrewwith a
screwdriver, as shown in Fig. 12. Thengive the weight
a 10 ~ 15mmslideoutward. After thisadjustmentonce
made, no adjustment is required any moreeven ifyou replace
the cartridgewith a new one.
ANTI-SKATING DEVICE ADJUST
MENT
Finally,apply the properamount of anti - skatingdevice,
in accordancewith the selectedtrackingforce.Simplyturn
the anti-skatingdevicedial tothe number that corresponds
tothe trackingforce in grams(Fig.13).
CONNECTION TOTHE STEREO
AMPLIFIER
The phonoinputs onthe amplifier to which the turntable
should be connected must be chosen in accordance with
the type of phonocartridge tobe used.
• With movingmagnet or inducedmagnettypecartridge:
Connect to PHONO MAG inputs on amplifier.
• Withlow-outputmovingcoil typecartridges:
Connect to PHONO MC inputs. If these arenot provided
on youramplifier, a step-uptransformerwill be required.
ConsultwithyourPioneerdealer.
• Withcrystal or ceramiccartridge:
Connect to PHONOCRYSTAL orAUX inputs.
In either case,connect thered output plugfrom the
turntable tothe amplifier'srightchannelinput, the white
plug tothe leftchannelinput.
The thirdwire(black)with the split lugonitsendisthe
groundwire.Connectthis tothe GROUND orGND terminal
of youramplifier. Donot forget to makethisconnection,
because itis vital for avoiding humand noise.

The PL-12D isa two-speed type; 33-1/3 rpmand45 rpm.Setting the
iever to either speed position will automatically setthe turntable for
operation at th?t speed.

EP RECORD ADAPTOR
AnEP recordadaptor is supplied inthe accessory group,whichpermits
45rpm records with large centerholes tobe played.When the adaptor
is notin use,keep itonthepin located inthe upper right ofthe base
plate.
Fig-17

HOWTO OPERATE THE TURNTABLE
1.Putthe record tobe played onthe turntable.
2. Remove the styluscover.
3.Setthe functionlever to position ON/UP. The turntable
begins to rotate.
4. Setthe speedselector atthe correctposition: 33or 45rpm.
5. Take the tonearm offits rest and move it over the initial
recordgrooves, orthe section from which you want to
play the record.
6.Setthe functionlever to position DOWN. Playingbegins.
7.Attheendofthe record,move the functionlever to positi-
on OFF. The tonearmwill lift from the record andcan then
be returnedmanually toits restposition.
IMPORTANT! OBSERVE CAREFULLY
1. Nevertouch the speedselectorleverunless the turntable
is rotating. The speed canbe changedonlywhile the turn-
table is rotating.
2. Neverobstruct the turntable by handwhile itis rotating.
This may causedamage.
3. Alwayskeep the stylusclean.Removedustwith a soft
brush.
4. Alwayskeep your records scrupulously clean,too. Clean
themwith a commerciallyavailable recordcleaner or cloth.
5. Never touch the styluswithyour finger. Handsoff.

WHAT TODOIN CASE OF TROUBLE
Wow (unstablesound)
Hum (low-pitched noise)
Howling(loud roar)
Oil onthe belt, motor pulley or innerturn-
tablerim.
No groundconnection.
Output cable too close to amplifier'strans-
former.
Occurs onlywhenvolume is turned up.
Caused by soundfromloudspeakers hitting
phonocartridgedirectly.
Wipe clean. Usea softclothwith a little
alcohol but never benzine orthe like.
Check connection of blackgroundwire to
amplifier's GND terminal.
Change turntableposition,move output cable
away from amplifier.
Turndownvolume.Moveturntablefurther
away fromloudspeakers.
LUBRICATION
Before applying oiltothe turntable,remove the turntable
platter by using the following procedure:
1. Return the tonearmonto thearm rest,thensupport the
tonearm with thearm clamper ofthearm rest.
2. Remove the drive belt withfingersfrom the motor pulley.
3. Pull the turntableplatterupwardwith two fingers inserted
into the turntableplatter's two openings. See Fig. 18.
If the turntable platter should notbe removedeasily,
pull itup strongly,withcaretaken notto damage any
part ofthe turntable.
WHEN LUBRICATION IS REQUIRED . . .
Mechanical noises andwowand flutterusuallyresult from
the lack of lubricant in rotatingparts.Lubricate the specified
spots at leastonceevery two months if yourturntable is
used for home entertainment, andtwoto three if used for
professional purposes.Apply oneortwo drops tothe base
of the centershaftFig. 19.
When lubricating, be careful nottoletoil adheresuch as
the motorpulley,belt, or innerrim. Ifoil shouldadhere to
these parts, wipe itoff with a cloth moistened withpure
alcohol.
WHEN LUBRICATION IS OVER ...
Replace the turntableplatter onthe centershaft,thenre-set
the drivebeltaround the motorpulley.
