High-end amplifierreda
The premium mono power amplifier delivers a sophisticated conceptual design – the discretely designed instrument amplifier configuration ensures extremely low noise and enables fully symmetrical signal paths. This is complemented by the MCS+ circuit and signal-current feedback, which enable superior sound quality andredhigh signal-to-noise ratio. Massive power supply and two risersredcontrolled amplifier units, each with high-performance transistors specially developed for audio applications in eight stagesredThe output circuit, with its further reduced internal impedance, achieves a damping factor of 1.000.
Mono amplifiers Accuphase they have been in the OSP for a long timeredthe world's high-end audio scene, and many of the models have become legendary in the history of sound. The M-6200 is the successor to the M-6000, but its design has completely rethought the concept of a power amplifier. With its outstanding performance, the M-6200 clearly demonstrates what an ideal mono power amplifier can achieve.
By using two completely separate power stages, the M-6200 further reduces noise levels and enables extremely precise and nadAdvanced speaker control.redThe connection increases the output current and provides extremely low output impedance. Negative feedback with the signal nadzorom and other technical improvements enable a damping factor of more than 1.000 to be achieved, which enables stable operation even inredat low loads. In the input circuit it provides a riseredconnection and precise gain calibration results in minimal residual noise, which is reflected in incredibleredsignal-to-noise ratio: 127 dB at maximum gain and 133 dB at -12 dB gain setting. Inside, every aspect of the amplifier has been redesigned, using only the highest quality components and materials. Two identical amplifier units, each equipped with newly developed high-performance transistors for audio applications, ensure excellent performance.
This allows for a low internal impedance of the output circuit and enables constant voltage speaker control. It is also possible to use two M-6200 models per channel in bridged mode, increasing the system output to 2.400 W at 2 Ohms. Despite its imposing build, the M-6200 is a mono power amplifier that not only impresses with its exceptional power and dynamics, but also penetrates to the core of the music, reproducing even the smallest details with astonishing realism.
Low-noise instrumentation amplifier configuration and improved MCS+ architecture
Fully symmetrical signal paths with discretely designed instrumentation amplifier
The balanced input stage circuits use an instrumentation amplifier architecture, as found in high-precision measuring instruments, which provides perfectly balanced input parameters for the positive and negative parts of the signal, enabling superior symmetrical signal transfer performance.
MCS+ (Multiple Circuit Summing) circuitry for drastically improved signal-to-noise ratio
The input circuit of the amplifier section contains an additional innovation Accuphase: MCS+ (Multiple Circuit Summing). This technique significantly reduces residual noise while improving stability.
Signal-current feedback technique ensures superior phase characteristics in the high-frequency range
In the M-6200 model, feedback uses signal current instead of signal voltage. Due to theredDue to the low impedance, there is almost no phase shift at the feedback point. Thus, even minimal feedback allows for maximum improvement of the coupling parameters. This principle maintains stable operation and is ideal for power amplifiers that must handle a wide dynamic range from very low to high signal levels.
