Grounding. This product is equipped with a three prong IEC connector. Always use power cord with adequate
wire cross section and an electrical outlet that is grounded. If you do not know whether the outlet is grounded,
consult your electrician or local power company.
Power Cord Protection. Power supply cords should be routed so that they are not likely to be walked on or
pinched. Pay particular attention to cords at plugs, convenience receptacles and where they exit from the product.
Alwaysusepowercordswithadequatecurrentratingsandsafetycertications(UL,CE,TÜV,CSA,etc.)
Fuses.Forcontinuedprotection againstre hazard,replace fuseswith thesame typeand ratingof thefuses
specied.Whenchangingfuses,completelyunplugtheACcordfromthewalloutlet.Ifindoubtwhatfusestouse,
contactfactoryorauthorizeddistributor.
Tubes. During operation, the vacuum tubes get very hot. Allow at least 60 minutes after removing power for tubes
to cool down. Only after 60 minutes you can remove the protective tube cover, if tube replacement is required.
Cooling.Toensureproperventilation,thereshouldbenothingplacedontopoftheunit.Ventilationholesshould
beunobstructedwithatleast12”(300mm)ofemptyspaceaboveandaroundtheunit.
Turn-off when not using for prolonged periods of time.Duetoaspecicconstructionofthe250TLvacuum
tube,theELYSIUMampliercanbeleftintheONstateforlongerperiodsoftime.However,duetothepresence
ofhightemperaturesandhighvoltage,theampliershouldbeturnedoffwhennotattendedforlongerperiodsof
time.Also,itshouldnotbeleftintheONstateovernight.
Emergency shutdown.OntherealpanelELYSIUMfeaturesanemergencyshutdownswitch(the“mushroom”
switch).Thisswitchisintendedtobeusedonlyincaseofseveretubearcingorotherissuesthatwarrantfastturn-
off.Unliketheregularpowerswitchwhichinitiatesturnoffsequencewhichcanlastcoupleofminutes,depressing
the“mushroom”switchwillcutthepowerimmediately,preventingmoreseriousdamagetotheamplier.Whenthe
emergency switch is activated, standard power switch should be turned off as well. After the problem has been re-
solved(usuallythatmeanstubereplacement),theswitchisreactivatedbyturningitonclockwiseforaboutquarter
turn, at which point it will spring back. After that, regular on/off switch should be used to power on the unit.

GETTING STARTED
ABOUT YOUR AMPLIFIER
Your ELYSIUM Power Amplier was designed to provide a true high-end performance which
iswhichisaresultofcarefullydesignedcircuitandoptimizedcomponentselection.Thedesign
utilizesthehighestqualityparts,includingcustomdesignedtransformersandchokeswhichare
theresultofTrafomatic’s20+yearsofexperienceinthiseld.TheELYSIUMsitsrmlyontopof
the Trafomatic’s product lineup, challenging competition in any price range.
The design is based on Eimac 250TL direct-heated triode (DHT) operating in pure Class A.
The250TLtubeispairedwithtwohighlylinearEML20b-V4tubes,coupledviaanunconven-
tionalcustominterstagetransformer.Rectiertubeisthehighly-acclaimedEML5Z3.Thiscom-
binationoftubesandmatchingtransformersoffers70Wofunrestrainedoutputpowerwithall
sonicbenetsofsingle-endedampliercongurations.
Eimac 250TL tube has been designed for continuous operation under challenging conditions.
Thatrequiredaspeciallamentconstructioninordertosupportlifeof10000hours.Adisadvan-
tageofsuchconstructionislament’ssensitivitytofrequentpowercycling.
ELYSIUM employs automatic start-up/shut-down procedurewithtwo-steplamentwarmup
augmentedbyatwo-stephighvoltageturn-on,thuseliminatingrisksandmaximizingtubelife.
Automaticbias ensures optimizedperformance throughout lifeof thetubeswithout needfor
periodicadjustments.
FitandnishoftheELYSIUMarecomplementingitsimpressivesoundqualityandmakeita
center of attention in any audio setup.
TheELYSIUMhasonebalanced(XLR)andoneunbalanced(RCA)input.Thereareoutputsfor
four(4)oreight(8)ohmspeakers.
HANDLING AND REPLACING VACUUM TUBES
Manypeople have neverhad experience handlingvacuum tubes. Processisvery similarto
handling incandescent light bulbs. As with the light bulbs, you should not touch a vacuum tube
whenitisoperatingsinceyoucanburnyourself.Similarly,ifatubeisdroppedonahardsurface
it may break or change critical operating parameters.
Whenreplacingthetubes,allowsufcienttime,minimum60minutes,fortubestocooldownand
internal capacitors to discharge. Only then you can remove protective cover with glass panels
and carefully remove the tubes. Before you insert a tube you should make certain that the unit is
disconnected from the AC outlet. Inspect the tube for cracks and physical damage.
Makesurethatthepinsarestraight.Ifyouneedtostraightenthepins,beverycarefulasitmay
cause the glass envelope to break, causing the tube to lose the vacuum and fail as soon as the
unit is powered on. Carefully align the pins with the socket and gently insert the tube. Replace
theprotectivecoverbeforeconnectingELYSIUMtotheACpower.
Never force a tube into a socket.
Onlythesametypeofvacuumtubescanbeused–nosubstitutionsareallowed.Shouldyou
decide to buy replacement tubes from Trafomatic Audio, rest assured that they were fully tested
before the shipment.

PACKAGING
Savetheoriginalpackaginginadryplace.Thepackaginghasbeendesignedtoprotectyour
devicefromstressesincurredduringshipping.Usingpackagingdifferentfromtheoriginalin-
creases risks of shipping damages.
PREPARATION FOR USE
Placeyourunitonaat,stablesurface.
