Aune este un amplificator portabil de casti in clasa A conceput pentru orice casca fie ea in-ear, on-ear sau over-earCa si produs este compus din triode individuale, ceea ce duce la sunt extraordinar de echilibrat, atat al frecventelor joase, medii cat si cele inalteFiind un amplificator in clasa A are o putere de iesire de 40MW, fiind destinat si castiilor cu 32 Ohmi impedantaAune 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 amplificareAune 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 stangin 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 produsAune 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 40MWCarcasa 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 componentsIndividual 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 outputOutput 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 supplyA 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 controlB1 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 circuitMain PCB of B1 adopts 4 layers
of excusive PCB for high frequecncy and is designed by porfessional
engineer with ten years 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 componentsB1 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 timeB1 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% aluminumB1 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
