The XA8800MNu is a power amplifier dual mono, with a structure based on a circuit of negative feedback, fully symmetrical. This model is characterized by its great sound quality and style is elegant and harmonious.
The amplification circuit with negative feedback is of the type fully symmetrical and complementary.
The major advantages of this structure can be summarized as follows: power, low distortion, dynamic, rich, excellent capacity control, operating reliability, excellent sound.
The amplification circuit can be divided into three stages: the first stage adopts transistor paired Motorola MJE350/MJE340 high quality, the second stage uses transistors paired Toshiba 2SC517/2SA1930, while the output stage uses three pair of transistors matched Sanken 2SC3264/2SA1295 high power.
As in all the products of Xindak, the components are selected and of high quality. The power is supplied by toroidal transformers high quality 350W from a bridge rectifier high-speed 50A and capacitors Rubycon 60,000 uF.
The power supply of the amplification of current is supplied from the transformer, by using separate lines for filtered and de-skew, high-speed, low-noise, low-impedance and properly shielded.
These measures contribute to reduce the interference and to improve the purity of the sound.
In addition, these power amplifiers are equipped with features of self-protection that ensure an extremely reliable.
Sound characteristics: The circuit quality and the selected choice of the best components make the sound of this unit is extremely sweet, but at the same time characterize it, with great energy and power.
Great is the dynamic, with a stage very extended. The sound is extremely clear, grand and elegant, alive and rich.Technical Specifications
