
TheBiviumismachinedfromasolidblockofaircraftgradealuminum,thereforeitismuch
heavierthanitlooks.Lifttheamplifierwithgreatcare,oraskforassistancewhentryingto
removeitfromthepackaging.

ThepackagingmaterialisspeciallydesignedtowellprotecttheBivium.Werecommendyouto
keeptheoriginalpackagingincaseyouneedtotransporttheamplifierinthefuture.

Preparations
Biviumisalinestagepreamplifierwithseparatepowersupply.InstallBiviumonarigidandstable
platform.Avibrationfreeplatformwillhelpextractingtheoptimalsonicperformance.
MakesurethemainpowerswitchisintheOFFposition(O)beforeconnectinganypowercable.
ConnecttheBiviumtothepowersupplyunit,usingthetwospecialDCpowercablesenclosedin
thepackage.The4pinDCcableisfortheanalogsupplywhereasthe3pincableisforthedigital
andcontrolcircuitry.BothDCcablesareterminatedwithLEMOconnectorequippedwithspecial
lockingmechanism.Pleasereleasethelockwhenunplug.



AlwaysuseanACpowercordwithgroundwire.TheBiviumpowersupplymustbeearthed,both
forsafetyandsonicreason.Togetthebestsoundquality,makesurethatallyourHi‐Fi
equipmentsareconnectedintoonemainssocket.
Connectyouraudiosignalsources,forexampleCDplayer,SACDplayer,radiotuner,etc,tothe
audioinputsocketsontherearpaneloftheBiviumpreamplifier.Thenconnectthepreamplifier’s
audiooutputtoyourpoweramplifier.

Audioinput1to3arebalancedwhileinput4to5aresingleended.TheBiviumaudiocircuitis
fullybalancedallthewayfrominputtooutput.ThereforebalancedXLRcableispreferredforthe
bestsoundquality.Anyaudiosignalwillbeconvertedintobalancedmodeinternallybythe
Bivium,sotheaudioperformanceisnotcompromisedevenwhenunbalancedRCAcableisused.
Thebalancedaudiooutputsarewiredaspin1Ground,pin2hotandpin3cold(Complytothe
AES48‐2005standard).Audiophasecanbeswitchedmanuallytobecompatiblewithsignal
sourcewiredindifferentfashion.TheBalancedoutputandsingleendedoutputaredrivenby
separateamplifiercircuitsandtheycanbeusedsimultaneously.

Beforeplayingyourfavoritemusic,turnthevolumedowntotheminimumfirsttoavoid
accidentalhearingdamagebyexcessiveloudness.Turnupthevolumeslowlyuntilitis
comfortable.Thensitdownandenjoy.
Whenyouhavefinishedlistening,pressthepowerbuttononcemoretotoggletheBiviumback

Input Settings
InputName,InputPhase,TheaterBypassandVolumePresetarechanneldependentparameters
thatareadjustedseparatelyforeachinputchannel.Adjustmentsoftheseparametersaremade
totheactivechannelbeinglistenedonly.Toadjusttheseparametersonanotherchannel,exit
SetupMenuandswitchtheinputchannel.
Input Name
Chooseyourdesiredequipmentnamefromthelist:AUX,CABLE,CD,DAB,DAC,DAT,DVD,DVDA,
GAME,HDTV,LD,PC,*PHONO,SACD,SAT,TAPE,TUNER,TV,VIDEO.
*RIAAequalizerisnotinstalledintheBivium,externalphonopreamplifierisneededforvinyldisc
playback.

Input Phase
Biviumisanon‐invertingamplifierthatdoesnotreverseaudiophase(preservessignalpolarity).
Ifitisnecessarytoinvertaudiophasedeliberatelyinordertomatchwithotherequipment,select
Invertedintheinputphasemenu.Thephaseinversionisonlyvalidfortheselectedchannel.A
scrollarrowsignwillappearonthedisplayindicatingphaseinversionisactivated.

Theater Bypass
TheTheaterBypassallowstheBiviumtobeconnectedtosurroundsoundprocessorandshare
thesamepairofleftandrightloudspeakerwiththesurroundsoundsystem.WhenTheater
Bypassisactivated,theBiviumwillswitchitselftotheunitgainposition(0dBgain)automatically.
Inthiscase,theBiviumwillbehaveasabuffer.Volumecontrolwillbehandledbythesurround
soundprocessorupstreaminthesignalchain.

Volume Preset
Ifyouhaveasourceequipmentthathasparticularlylower(orhigher)outputthantheothers,
youcancompensatethisbyusingtheVolumePreset.ForexampleifyourTuneris6dBquieter,
youcouldsettheTunerVolumePresetto+6dB.WiththeVolumePresettunedright,thesound
levelwouldremainthesameuponswitchingbetweenTunerandotherchannel.

General Settings
LRBalance,VolumeControlSpeed,VolumeUnit,MuteVolumeandDisplayBrightnessaregeneral
parametersthataresharedamongallinputchannels.

LR Balance
TheLeftRightbalanceoftheBiviumitselfisextremelywell(below+/‐0.05dB)whichrequiresnot
adjustmentatall.TheLRBalanceadjustmentfeatureisonlyintendedtocompensatethe
differencebetweenleftandrightvolumecausedbyotherequipment.

Volume Control Speed
AdjustthespeedofvolumecontrolbychoosingbetweenFineandCoarse.Finemodeoffers160
volumestepsforhighresolutionadjustment,in0.5dBincrement.Coarsemodeoffers80volume
stepsforfastadjustment,in1dBincrement.

Volume Unit
Numericmoderepresentsvolumeinauserfriendly0to160levelscale.
dBmoderepresentsvolumeinaprofessionalmannerinoveralllogarithmicgain.

Mute Volume
When‐55dBisselected,thepreampwillattenuatetheoutputtoaverysoftlevelwheneverthe
MUTEbuttonisdepressed.If‐120dBisselected,thepreampwillcutofftheaudiooutput
completelywhenmuted.

Display Brightness
Thereare5differentlevelsofdisplaybrightnessavailable,level5beingthebrightest.Oryoucan
chooseAuto,whichwillbrightenupthedisplayuponanycontrolcommand,andthendimmedby
itselfafterabout2minutes.

Restore Factory Setting
PressandholdthePowerbuttononthepreamplifierfrontpanelfor5seconds,theBiviumwill
entertheRestoreFactorySettingmenu.Activatingthiswillerasealluserenteredsettingand
restoreeveryparametertotheoriginaloutoffactorystate.


Safety and Protection

DC protection
TheBiviumprotectstheloudspeakerfromDCleakage.IncaseofthepresentofDCleakage,the
audiooutputwillbecutoffautomatically.

Short circuit protection
TheBiviumisdesignedtowithstandmomentaryshortcircuit.However,donotshortcircuitthe
audiooutputintentionally.



12

Maintenance
Cleaning
TheBiviumrequiresnoadjustmentandwillremaininoptimumconditionformanyyears.
Cleanthesurfacewithsoftdryclothonly.Donotuseanysolventorcleaningagent.
Remote Control Battery replacement
Unscrewthebottomplateoftheremotecontrolunit.ReplaceoldbatterieswithAAAsizedrycell
alkalinebatteries(LR03).Reclosethebottomcoverafterbatteryreplacement.Alwaysreplace
bothbatteriesatthesametime.Mixingnewandoldbatterieswillreducebatterylife.
Fuse replacement
OnlyreplaceFusewiththesameratingasthesuppliedone.
For220VACelectricitysupply,useT3Adelayedfuse.
For110V,useT6Adelayedfuse.
