INTRODUCINGTHEH‐3000PHONOSTAGE

TheH‐3000isAllnicAudio’stopofthelinephonostage

doing,providinganenormousservicetorecorded

musiclistenerseverywhere.

TheH‐3000hasthefollowingfeatures:

• LCRTYPERIAAEQUALIZATION:

RIAAequalizationisaspecificationforthecorrect

playbackofvinylrecords,establishedbythe

RecordingIndustryAssociationofAmerica.The

purposeofthe

equalizationistopermitlonger

playbacktimesandimprovesoundquality.

RIAAequalizationisaformofestablishingaflat

frequencyresponsefortheplaybackofrecorded

music.Thenecessityforthisequalizationprocess

arisesfrommechanicaldifficultiesinherentin

recordproduction.Inordertopreventthecutting

needlefromover

‐cuttingintothenextrecord

frequenciesareattenuated.Inthetrebleregion,in

bythenoiseinherentinmovingastylusoverand

throughamodulatedvinyl surface,sometreble

frequenciesareboosted.Withtheapplicationof

thecorrectfilteringtechniquesonplayback,the

resultisaflatfrequencyresponsewithbettersignal

tonoiseratios.

Therearefourde‐emphasismethodsthatcanbe

appliedatplayback:

A. Activefilters(Negativefeedbacktypes):

Differentquantitiesofnegativefeedbackare

applied,

withdeeperfeedbacktothehigh

frequenciesandshallowertothelowfrequencies.

Thebenefitsofthismethodareimprovedsignalto

noiseratios,lowcostandconsistentoperation.

Someoftheshortfallsarelooserbassreproduction

andpossiblyapinchedandcompressedhighfrequency

playbackduetoexcessfeedback

ratios.

B. Passivefilters(CRtype):

‐ ThefrequenciesarefilteredtofittheRIAAspecification

byvaryingtheamountofattenuationatdifferent

frequenciesthroughacomplexcapacitor‐resistor

network.Thistechniqueresultsinnovoltageoverload,

purerreproduction(becausethereisnofeedback),and

moreaccurateRIAAcompensation.However,

thereare

problemsbecausethesystemprovidesnogain,and

insertionlossandimpedancematchingissuesarise.

C. Hybridfilters(useofbothCRandnegative

feedbacktypes):

Inthismethod,bothtypesoffiltersappliedseparately;

anactivefilterisappliedtothelowfrequenciesanda

passivefilterto

thehighfrequencies.Unfortunately,

boththeadvantagesanddisadvantagesofeachof

thesetwotypesoffilters,alreadydiscussed,affectthe

playbacksystematthesametime.

D. LCRfilters,whichareusedintheH‐3000:

Twopiecesofalinearreactor(akindofchokecoil)

comprisethe

mainpartofthesefilters,assistedby

preciseCRfilters,inordertolowerimpedancesand

insertionloss.

Invacuumtubecircuits,activeandpassivefiltersusually

areoperatedononehundredpluskiloohmsof

Furthermore,anLCRRIAA
