ATI AT6002 amplificator HIGH END MORRIS KESSLER SIGNATURE
 
 
Face parte din seria AT6000 avand 300W /canal
 
Avand structura modulara, acest amplificator este disponibil cu canale in numar de 2 pana la 7. Modelul prezentat este cel cu 2 canale
 
Acest model PURE BALANCE DESIGN foloseste feedback pentru alimentare, temperatura si DC Servos pentru performanta imbunatatita.
 
Amplifier Technologies, Inc., unul din cai mai prolifici producator al celor mai bune amplificatoare HIGH END din ziua de azi, a introdus pe piata a noua serie proiectata chiar de presedintele si inginerul sef Morris Kessler.
Seria 6000 este ultimul produs dupa o pauza de 10 ani, timp in care seriile vechi au dominat piata atat ca produs ATI cat si ca OEM sub alte denumiri de marca.
Aceasta serie este un model de referinta avand semnatura celebrului Morris Kessler pe panoul frontal.
 
Pe langa semnatura Kessler, aceasta serie este o noutate in din mai multe puncte de vedere:
 
1.Ca toate produsele Kessler, acest amplificator este total balansat si diferential, dar fata de modelele anterioare care erau balansate in punte, seria 6000 foloseste un modul de intrare unic dar cu iesire 
dual diferentiala deoarece se pastreaza avantajele unui semnal balasat si un zgomot redus cu 50% 
2.Designul foloseste un feedback al curentului in loc de fedback-ul voltajului deoarece amplificatoarele cu feedback la alimentare sunt rapide cu rata de taiere virtual nelimitata avand o mult mai buna redare a sunetului din filmele si muzica de azi.
3.Folosirea sistemului Thermaltrak. Spre deosebire de designul traditional care foloseste diode si tranzistori externi lipiti de radiatoare si corecteaza aceste detalii printr-un bias ajustat, echipamentele Thermaltrak 
au senzori de temperatura in aceeasi carcasa cu tranzistorul de iesire optimizand bias-ul in timp real
4.Seria 6000 foloseste un servo dual pentru pastrarea curentului continuu rezultand intr-un curent continuu la iesire redus la un nivel insignifiant.
5.Amplificatoarul foloseste un model refacut al cablajului imprimat. Sunt in continuare modulare cu alimentarea pe o singura placa, dar acum componentele cu curent alternativ sunt pe o singura margine a placii, 
departe de circuitele de intrare rezultand un raport semnal/zgomot imbunatatit.
6.Toate amplificatoarele folosesc transformatoare toroidale duble, alimentare dubla si doua cabluri de alimentare fiind acum un model complet dual mono, iar amplificatoarele multicanal au destul curent pentru a sustine 
orice necesar de curent inainte limitat de sigurante.
 
Toate amplificatoarele au 300W RMS  de la 20 Hz la 20 kHz cu nu mai mult de  0.03% THD la 8 ohmi, toate canalele amplificate, si 450 W RMS in 4 ohms in aceleasi conditii
 
Sunt disponibile in variante de carcasa 17" si rackmount 19" si au garantie transferabila 7 ani garantie.
 
Despre Amplifier Technologies: fac parte dintr-un grup ce detine firmele ATI, Audioaccess, B&K, BGW si Theta Digital , iar produsele sunt fabricate exclusiv in USA.

AMPLIFIER TECHNOLOGIES, INC INTRODUCES THE MORRIS KESSLER SIGNATURE AMPLIFIERS AVAILABLE WITH TWO TO 7 CHANNELS. 
THE PURE BALANCE™ DESIGN USES CURRENT FEEDBACK, THERMALTRAK OUTPUT DEVICES AND DC SERVOS FOR IMPROVED PERFORMANCE 
 
 
 
Amplifier Technologies, Inc., the prolific manufacturer of many of the high end’s best amplifiers today introduced a new series of amplifiers designed by their president and chief engineer, Morris Kessler. 
The 6000 series amplifiers, available with 2 to 7 channels, are the company’s first new amplifiers in over a decade. Furthermore, their “signature series” designation with a facsimile of Kessler’s 
signature on the main panel acknowledges the special nature of these designs.
 
Beyond Kessler’s personal identification, these amplifiers are new in more significant ways.
1. As in Kessler’s previous top-of-the-line designs, these amplifiers are fully balanced, differential amps, but unlike his earlier balanced designs which were essentially balanced bridged amplifiers, 
the 6000 series uses only a single input stage with dual-differential output stages. The reason: the advantages of balanced designs are retained and noise is reduced by 50%. 
2. The design uses current feedback instead of the more common voltage feedback. The reason: current feedback amplifiers are faster with virtually unlimited slew rate and are better able to 
reproduce today’s best music and film sound. 
 
3. Kessler used Thermaltrak output devices for the 6000 series. Unlike traditional designs where external diodes or transistors attached to the heat sinks track the amplifiers operating conditions 
and use the details to adjust bias, Thermaltrak devices have the temperature sensing device in the same package as the output transistor. The results: bias is optimized in real-time. 
 
4. The 6000 series use dual DC servos to track and maintain DC offset. The result: DC in the amplifier’s output is reduced to insignificant levels. 
 
5. These amplifiers use a revised PCB layout. They are still modular with the complete amplifier including the power supply parts on a single card, 
but now the AC components are on one edge of the board and away from the signal input. The result: improved signal-to-noise performance. 
 
6. All of the amplifiers in the series use dual toroidal transformers, dual power switches and dual line cords. The results: the AT6002 is now a complete dual-mono design and the amplifiers 
with many channels, as in the 7-channel AT6007, can be hooked-up to two independent 20 amp circuits for greater sustained output power than is possible from a single AC circuit.
 
All the amplifiers in the 6000 series are rated at 300 Watts RMS from 20 Hz to 20 kHz with no more that 0.03% THD at 8 ohms with all channels driven and 450 Watts RMS at 4 ohms under the same conditions. Signal-to-noise ratio is typically 128 dB referenced to full output so each amplifier in the series is capable of playing back the full dynamic range available on today’s lossless recordings. 
 
 
All ATI amplifiers are available in standard (17”) and rack-mount (19”) chassis with domestic (117V) of Export (220 to 240V) chassis and are covered by ATI’s 7-year transferrable warranty.
