XA6800R(II) Integrated Amplifier The Xindak XA6800R (II) adopts a new look and internals. It is a pure class A integrated amplifier designed with high standards in mind for our customers to enjoy their preferred music. Derived from the XA6800R, internals are made of carefully selected components with both objectives to improve sound performance and reliability. Operating as a pure class A amplifier, good heat dissipation is ensured through the design of copper heat conduction bridges on both sides of the amplifier. Not only does this provide a stable and reasonable operating temperature, but it enhances the power output. A symmetric design completes the picture around an R type power supply of excellent properties. These are few examples of details attached to the building and circuit design of this new integrated amplifier. Two meters across the front panel not only inform about the operation of the amplifier, but with a blue backlight also improves the aesthetic. The black housing, derived from our acclaimed High-End PA Power Amplifier, adds to the striking look. To complete the picture, the versatility of the new XA6800R(II) reaches new territories with the addition of a USB entry (on top of 4 analog inputs) to connect your computer and enjoy your digital music library. Thus equipped, the new XA6800R(II) is ready to become the heart of a simple to implement solution with astonishing performances that only class A amplifiers can bring to music lovers. package: carton, Gross Weight: 21kg Net Weight: 19kg Dimensions(mm):430*410*140
