Aune este un amplificator portabil de casti in clasa A conceput pentru orice casca fie ea in-ear, on-ear sau over-ear
Ca si produs este compus din triode individuale, ceea ce duce la sunt extraordinar de echilibrat, atat al frecventelor joase, medii cat si cele inalte
Fiind un amplificator in clasa A are o putere de iesire de 40MW, fiind destinat si castiilor cu 32 Ohmi impedanta
Aune B1 controleaza 2 volume de iesire, atat pentru casti in-ear cat si pentru on/over-ear, aceste casti avand comportamente diferite cand vine vorba de amplificare
Aune B1 a implementat STM85 MCU pentru controlul procesorului, AR8501 ca cip central pentru performanta si putere. Placa de baza PCB are 4 layere distincte pentr a creea balansul perfect intre canalul drept cat si stang
in Aune B1 se folosesc capacitoare de mare calitate COG din tantalum pentru a reda intr-un mod acurat sunetul, calitatea acestuia fiind una superioara pentru clasa din care face parte acest produs
Aune B1 are un acumulator de 4000MA baterie de lithium care duce la posibilitatea de a asculta 10 ore muzica la 32MW si 5 ore pe 40MW
Carcasa este din 100% aluminum taiata cu precizie la CNC, gradul de finisare fiind astfel unul premium.
The Aune B1 is an exceptionally built portable headphone amplifier made with high quality components. The Aune B1 features Class A operation, adjustable current, and now fully supports CTIA headphone jacks.
The 1st individual component-made class A HIFI portable headphone amplifier with adjustable current in the world
Main amplifying circuit of B1 being consisted of individual triode components
Individual component: top-grade amplifiers are almost designed by individual components, individual component-made amplifier has a large switching rate and transient state, individual component-made amplifier has characteristics of quite wide frequency representing excellent extension of high frequency, powerful low frequency as well as gradation −distinct middle frequency very well.
B1 adopting bias design of pure class A output
Output stage of B1 adopts bias design of class A amplifier and provides 40MW power of class A for 32ohm headphone , characteristics of class A could not only enable amplifying circuit of B1 to gain a perfect extension of high frequency, powerful low frequency and clear middle frequency , but also give a warm ,sweet and intimate feeling to its listener .
B1 has two shifts of gain controls and current outputs for option of earbud and headphone , which adapt to them very well , user could choose two output currents to get two states of class A for joy .
B1 employing a design of internal +-9V power supply
A super good power supply is the gurantee of perfomance of amplifier,especially positive and negative symmetrical power supply is the most difficult thing to solve on portable amplifier ,B1 employs a design of positive and negative power supply with special and low ripple and large current,which give a super powerful engine for B1 and provide continuous power for the whole amplifier.
B1 adopting STM85 MCU to realzie core control
B1 adpots a central chip AR8501 to realzide state and protection control , as well as battery control and monitoring , which detect state of the whole unit and respond to various situations promptly, B1 is a portable amplifier with centralized control and has protection circuit of electric relay for headphone amplifying.
B1 adopying professional layout of circuit
Main PCB of B1 adopts 4 layers of excusive PCB for high frequecncy and is designed by porfessional engineer with ten year′s work experiences,headphone amplifying part uses stream-typed circuit design and main amplifying circuit miirrior image to ensure left and right sound channel are entirely same , B1 is a high standard hifi design.
B1 adopting top-grade hifi components
B1 adopts high quality HIFI components that are only for top-grade hifi amplifier,such as American conductive plastic potertiomnter ,VISHAY SMT metal film resistor,COG capacitor,tantalum electrolytic capacitor with super-low inner resistance and hifi audio output tube,all these make B1 a tops −grade hifi components-made portable earphone amplifier.
B1 having a high battery capacity and long battery running time
B1 uses 1 pc OF 4000MA lithium battery with super-low inner resistence ,it could continuously work for 10 hours at shifting position of 32ohm class A 20mw and for 5 hours at shifting position of 32ohm class A 40mw ,B1 could work for a long time .
Chassis of B1 being cut out by 100% aluminum
B1 uses 100% aluminum to cout out its chassis,6 sides of which are finished by CNC , slot with 45 angle on side face is the most difficult part to handle,surface of it is finished by anodic oxidation and brushing treatment and characters on surface are done by laser ,B1 is a portable amplifier with high quality chassis

Avand originile in cea mai populara platforma chineza de Hi-Fi (hifidiy.net, aproape un million de utilizatori inregistrati), brandul Aune fondat in 2004, inseamna produse de top in domeniul audio, fie ca e vorba despre nisele numite desktop, auto sau portabil. Aflata in proprietatea Ao Lai Er Technology, marca Aune este genul de mini-erou aparut de nicaieri care reuseste nu numai sa le tina piept zmeilor din industrie, dar chiar si sa le rada in nas de multe ori.
Avand in spate o senzationala echipa de cercetare/dezvoltare, Aune a inceput sa atraga atentia lumii audiofile prin produsele excelente pe care le propune (senzationalele amplificatoare de casti cu DAC-uri DSD si playere portabile care decodeaza fisiere Hi-Res), dar mai ales printr-un raport calitate/pret absolut de invdiat. Rezumand, declaratia de intentie a celor de la Aune este simpla: sunet superb.
