In designing the A 200 output stage, the T+A goal was to combine maximum amplifier power with audiophile sound characteristics. On the one hand this means 250 Watts of continuous power per channel, and on the other hand this substantial power does not result in a reduction in terms of subtle detail, resolution and fine dynamics.
The A 200 heatsinks are both a technical necessity and a design statement: they show off every watt of power in impressive style as well as ensuring efficient heat dispersion – even under maximum load. The A 200 output stage was developed with the aim of functioning either as a potent complement to an existing system, or as the high-performance end of a perfectly matched chain of specialised audiophile devices in combination with the Series 200.
By this means they have succeeded in converting raw power into unsurpassed audiophile performance. All circuits and circuit boards are designed and executed by their own development team, and the PURIFI modules implemented within them. The damping factor of the A 200 can be reduced if a warmer or softer sound image is desired in combination with particular loudspeakers.
The A 200 Class D output stages incorporate PURIFI Eigentakt™ technology. This platform, developed by the Danish technology company, is currently the world’s leading fundamental design for Class D output stages, as it eradicates the disadvantages of the previous generation of digital amplifiers. Until now digital amplifier designs were limited by their high dependence on the impedance of the loudspeakers connected to the system, by distortion in the output signal, by phase noise and increased distortion at high power levels. In contrast, the outstanding feature of this new circuit design is its outstanding measured data, making it the obvious choice for audiophile applications.
The final trace of induced interference is eliminated by the intelligent recharging of the T+A reservoir capacitors fitted to the units. Over many years of development T+A engineers succeeded in developing capacitors which recharge 100,000 times per second – 2,000 x faster than conventional capacitors. This is necessary in order to ensure that they respond to extremely brief signal spikes, and are always able to deliver the correct quantity of electrical energy. The sine-wave mains sections are hard units, i.e. they do not collapse even under the most severe load; they provide the output stages with absolutely constant voltage.
The HV circuit technology is unique in the world, and is employed in the voltage amplifier stage. The high operating voltage resulting from the overall circuit design ensures extremely linear reproduction of the audio signals, and provides totally natural imaging and dynamics from every recording – without compromise, and without limitation. The technology also eliminates harsh feedback, to which audio sound is very sensitive.
The Intelligent Safe Control (ISC) is comparable with the ABS of a sports car: the micro-controller uses numerous sensors to provide constant monitoring of the temperature, load or clipping states, and intervenes in an intelligent manner in order to return the parameters to their permissible range.
