INTRODUCINGTHEH3000PHONOSTAGE
TheH3000isAllnicAudio’stopofthelinephonostage
model.LikeallAllnicAudioproducts,itusesPermalloy

TheH3000hasthefollowingfeatures:
LCRTYPERIAAEQUALIZATION:

thecorrectfilteringtechniquesonplayback,the

tonoiseratios.
Therearefourdeemphasismethodsthatcanbe
appliedatplayback:
A. Activefilters(Negativefeedbacktypes):
Differentquantitiesofnegativefeedbackare
applied,
withdeeperfeedbacktothehigh
frequenciesandshallowertothelowfrequencies.
Thebenefitsofthismethodareimprovedsignalto
noiseratios,lowcostandconsistentoperation.
Someoftheshortfallsarelooserbassreproduction
andpossiblyapinchedandcompressedhighfrequency
playbackduetoexcessfeedback
ratios.
B. Passivefilters(CRtype):
‐ ThefrequenciesarefilteredtofittheRIAAspecification
byvaryingtheamountofattenuationatdifferent
frequenciesthroughacomplexcapacitorresistor
network.Thistechniqueresultsinnovoltageoverload,
purerreproduction(becausethereisnofeedback),and
moreaccurateRIAAcompensation.However,
thereare

C. Hybridfilters(useofbothCRandnegative
feedbacktypes):
Inthismethod,bothtypesoffiltersappliedseparately;
anactivefilterisappliedtothelowfrequenciesanda

boththeadvantagesanddisadvantagesofeachof
thesetwotypesoffilters,alreadydiscussed,affectthe
