OPTONICA
RX-1
PCM Digital Audio Adaptor

TheRX-1 unveilsa completelynewaudioerawitha widerange
of featuresandunique,innovativeideas.
A Dream Unit forAdventurous
Audiophiles
Sharp'sadvanceddigitaltechnology is backed upby innovative
semiconductortechnology.This has beencombinedwith its
sophisticatedaudiosystemexpertise,welldemonstrated inthe
OPTONICAseries.
Now,OPTONICA is announcing a new audio era with thein-
troduction ofa dreamunit - PCM digitalaudioadaptorRX-1.
Throughout its continuous,relentlessefforts in thisfield,
OPTONICA has developed the versatile,compact PCM adaptor
which can easily be connected toany homevideo.Featuring
itsimpressivebreakthrough in drop-outproofingcapability,
the RX-1isthe idealsolution to "analog"audiobarriersthat
criticalaudiophileshavelongbeenconfrontedwith.
The PCM (PulseCodeModulation)systemsetsaudiotechnol-
ogy ona completely new course,wellbeyondconventional
analogaudio. Itisthe systemwhichconvertsanalogsignals
intodigitalsignals for storing the data onthe videotape.First,
soundsignals are microscopicallydivided and thenencoded
intoeither 1 (presence) or0 (absence) and recordedonto
videotape.Thiseliminatesnoisewhichcouldveryoften be
mixedwith the musicsignals atthe time of recording.
Adaptable toAny Type of Video Cassette Recorder
HavingadoptedOptimumControlfunction, the RX-1permits
you to search forthe idealmatchingpoint,bestsuited toany
type of videocassetterecorder, VHSor Beta.Thismeansthat
theingeniousunitpromises you spectacularsoundquality
anytime,anywhere.
Theadaptabilitylevel is convenientlydisplayed onLED indi-
cators for yourquick,accuratereference.
OPTONICA's Unique Drop-Out Proof System with
99.995% Perfection
OPTONICA, by fullyutilizing a sophisticatedmemoryfunc-
tion, has developed a superbdrop-outsystem for dutiful,
accuratereproduction ofthe originalsound.Necessarydata
fordrop-outproofing are input atthe time of recording.Then
at the time of plaving,correction is done to nearperfection.
Theresult isa stunning99.995%correctioncapability.

2. Push "on"the powerswitch {1).
3.Switch the modeselector to "play"position.
4. Load a PCM tapeinto a video cassetterecorder.
5. Setthe videocassetterecorder'strackingcontrolknob to autoposition, ortothe
centerposition if manually set.
6.Connect a headphone tothe headphonejack (2).
7.Playback the videocassetterecorder andsetthe errormonitorswitch(two-way
monitorswitch) to "check"position.
8.Adjustoptimumcontrol by monitoringoptimumindicators.
9.Obtainmaximumtrackingcontrol by listening tothe checkingsignals.
10. Now,the tape Canbe playedbackanytime.
•Duringoptimumcontrol or trackingcontrol,turndown the amplifiervolume andset
themonitorswitch tothe "monitor"position.
•Once the initialoptimumcontrol and trackingcontrol is adjusted,there isno further
adjustment necesHryas long asthe videocassetterecorder is used.
•Always usea reliablevideocassetterecorder in excellentworkingcondition in order
toobtainmaximumperformancefrom the digitaladaptor.Always keepthe video
headsclean.
•Whenusing a prerecorded PCM tape,makesure it complieswith thePCM recording
standard.
Error Monitor Switch (Two-way Monitor Switch)
SourcePosition
•Recording and playbackconditions are monitored by headphoneswhen the switch is
in"source"position.
•When the switch isin "check"position, the headphonespick upthe intermittent
signalsound to indicatewhether the optimumcontrol or trackingcontrol is properly
set. The better the condition, the lessaudible the signalbecomes.
Usually, setthe trackingcontrol to "auto"position.When the signalsoundbecomes
quick and clearlyaudible, the playbackcondition ispoor. Proceed tosetthe tracking
controlmanually to obtain the optimumplaybackcondition. For manualsettings,
follow the instructionsbelow:
t.Listencarefully tothe signalsound.Count a number of signalsaudiblewithin a period
of fiveseconds.Turning ofa trackingcontrolknobwilleitherincrease or decrease
signalinterval. Setthe knobwhere the leastamount of signal is audibiewithin a
period of fiveseconds.Repeatthisseveraltimes to obtainmaximumtrackingcontrol.
When the trackingcontrolknob is turned,tracking is momentarilydisturbed.When
makingan adjustment,wait untilthe tracking is stabilized andno continuoussignal
sound isheard.
• The signalsound is onlyreproduced bythe headphoneterminal (2)andit won't be
reproducedthrough the speakers.
•Everytime a videocassetterecorder/videocassettetape is changed, be sure to make
trackingcontrol and optimumcontroladjustments.
•Whenrecording,pushback the switch tothe "source"position.
