THE T+A M200 DUAL MONO
THE T+A M200 Dual Monohas been developed with the sole aim of providing the ultimate in audiophile quality and performance – without any compromise or limitation. To this end the M 200 combines the fine detail, resolution and detail dynamics of our hugely esteemed A 200 stereo power amplifier with an output of more than 400 Watt. The M 200 is designed to feed just one loudspeaker, and this allows it to celebrate music in a manner which is even more audiophile, even more powerful and even more devoid of coloration than would ever be possible with a stereo power amplifier.
Its heatsinks are a technical necessity, but they are also more than that: at a single glance the innate power of this compact output stage is self-evident; naturally the heatsinks also ensure optimum heat dissipation – even under extreme load. The T+A M200 Dual mono power amplifier is the most potent final stage in any system configuration: either as a complement to an existing system, or – in combination with the Series 200 – as the pinnacle of a perfectly compatible chain of specialised audiophile devices.

In our opinion power is only a positive factor if it goes hand in hand with the highest possible sound quality, efficiency and precision. That is why the M 200 shares a large number of the technologies employed in its sister device: the A 200. At its core there is a completely new circuit topology which attains the optimum blend of efficiency, performance and sound quality by combining our unique HV and High-Frequency Sine-Wave mains section technologies with PURIFI Eigentakt™ power amplifier technology. This combination is crucial to obtaining maximum audiophile performance from unrestrained power. In contrast to the A 200, the M 200 does not need to share this technology between two loudspeakers; instead it delivers its performance uniquely and alone to a single speaker. This again helps to maximise the potential of the A 200. If particular loudspeakers require a warmer or softer sound image, it is possible to reduce the M 200’s very high damping factor.

HV CIRCUIT TOPOLOGY
The basis for the device’s exceptionally linear reproduction of all signals, and faithful dynamic imaging, is our voltage amplifier stage, incorporating HV circuit technology. This circuit’s high operating voltages create unsurpassed linearity. The HV concept needs no hard negative feedback with its inherent tendency to generate interference, and these problems are simply absent.

OUTPUT STAGE
The output stages of the M 200 are Class D power amplifiers based on PURIFI Eigentakt™ technology. This platform, developed by the Danish technology company, is currently the world’s leading concept for Class D power amplifiers, and avoids the disadvantages of earlier digital amplifiers. Previous digital amplifier designs were limited by being very load-dependent, and susceptible to the impedance of the loudspeakers in use, generating distortion in the output signal, phase noise and increased harmonic distortion at high power levels. In contrast, this new concept produces outstanding measured results, and is predestined for use in audiophile equipment:

• Extremely low harmonic distortion and intermodulation effects at all power levels
• Extremely low noise
• High damping factor
• Clean clipping
• Low losses, high efficiency
• Linear frequency response up to 60 kHz
• Completely consistent behaviour, regardless of load (see graphs for 4 + 8 Ohms)

MAINS SECTION
Although conventional switching mains sections offer advantages in terms of efficiency, they can generate induced interference which has a sustained degrading effect on sound quality. Our T+A High-Frequency Sine-Wave mains sections are the audiophile answer to this problem: their pure sine-wave clock, and a frequency more than twice as high as conventional mains sections, effectively block out such interference. The unit’s integral T+A reservoir capacitors with their intelligent refresh characteristics eliminate the last trace of induced interference: they are refreshed 100,000 times per second, which is 2000 times more frequently than ordinary capacitors. This is essential to enable them to respond to brief peak signals, and always deliver the correct quantity of electrical energy. Our sine-wave mains sections are “hard” power supplies, i.e. they maintain their performance even under the most severe loads, and provide the output stages with absolutely constant voltage.

INTELLIGENT SAFE CONTROL
Our Intelligent Safe Control (ISC) is comparable with a sports car’s ABS: numerous sensors feed data to the ISC’s micro-controller, which constantly monitors the temperature, load and clipping states, and intervenes intelligently in order to return the parameters to their permitted range.

SERIES 200.
The Series 200 represents a modern interpretation of our legendary MiDi systems. Starting with the iconic M-system in the 1990’s, and most recently continued by the Series 8, all of these systems have combined and continue to combine superb audiophile performance with an ultra-compact design of timeless elegance. The MP 200, A 200, M 200, DAC 200 and HA 200 embody our experience in each individual area, and make it accessible to compact systems in particular.

DESIGN PRINCIPLES
The Series 200 was developed with the goal of closing the supposed gulf between high-grade specialised individual devices – ‘separates’ – and a combined system for relaxed listening. And that’s why the Series 200 consists of now five units. The DAC 200 and HA 200 reference converter and pre-amplifier convert digital data into analogue signals, and constitute the heart of their system configurations: the DAC 200’s outstanding pre-amplifier and output stages make it the ideal core of a classic HiFi system with loudspeakers, whereas the HA 200 takes on a similar role in an audiophile headphone system.

Thanks to its Modular High-End Architecture (MHA) the MP 200 operates as a universal unit capable of delivering all modern music sources, from DAB radio to streaming. The A 200 output stage, generating 250 Watts power per channel into 4 Ohms, provides incredible performance with superb linearity and outstanding measured values. Thanks to the advanced technologies employed, the A 200 is able to exploit its full performance regardless of load, i.e. independently of the loudspeakers to which it is connected. The M 200 combines the fine detail, resolution and detail dynamics of the A 200 stereo power amplifier with an output of more than 400 Watt. It is designed to feed just one loudspeaker, and this allows the M 200 to deliver music in a manner which is even more audiophile,more powerful and even more devoid of coloration than would ever be possible with a stereo power amplifier. Although all the Series 200 devices offer outstanding levels of performance individually, the aim of their development was to make them even better when used together in a system. The integral T+A Link System has been fine-tuned to meet the specific requirements of the Series 200, with the result that every device is as universal as possible, as well as keeping interference signals completely separate from the analogue signal path: this ensures that the music remains just as clear and precise as it was when the artiste performed it.

EXTERNAL DESIGN
Like every T+A device, the Series 200 units were designed on the basis of our unified philosophy of “timeless reduction”. This principle endows all the equipment we produce with a shared visual DNA, without obscuring their individual qualities. For more than twenty years now this philosophy – with a few exceptions – has been the beginning and end of each design process: a clearly delineated double chamfer on the front panel, reminiscent of the iconic M-systems of the 1990’s, giving the devices a unique charisma. Precisely positioned lines and style accents give the illusion that the Series 200 devices are smaller than they actually are. Cooling fins and VU meters are an unmistakable indication of the units’ potential performance – even when the equipment is switched off.
