The Xindak XA6800R (II) is a audio amplifier Hi-Fi integrated designed with the highest standards of quality, the evolution of the popular model XA6800R.
This amplifier works in Pure Class A and produces an output of 30 Watts per channel.
The power supply section is based on a powerful type transformer, R-Core, characterized by excellent electrical properties.
The pre-amplification stage is symmetric and pilot two centres of power: they, too symmetrical, and equipped with six transistors bipolar BJT carefully selected and matchati.
The power transistors are connected to the fins of the external heat dissipation in the aluminum through the use of special copper bars shaped in the form of L, specially designed to optimize the passive dissipation.
This makes it possible to maintain a constant operating temperature of the Xindak XA6800R-II, and ensures reliability over time, allowing a dissipation fast and effective use of the heat generated by the polarization in Class A.
The design fully symmetrical dual-mono of the two audio channels and the central disposal of the transformer, R-Core optimize rationally the weight and reach the goal of avoidance of resonances in a mechanical system.
There are four pairs of line inputs (RCA) and a USB input for direct connection to a computer (Windows PC, MacOS or Linux).
The front is extremely elegant and has two power indicators Vu-Meter with blue backlight, the motor-driven volume control, the selector of the audio inputs and the power on command and power off. Technical Specifications:
