User manual XINDAK XA6950

[. . . ] Since the swift development on technology, there may be some outdated description which is not applicable any more, please understand. Our company does not assure that there will be no updating version on this manual when there is no mistake or neglect. [. . . ] Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus ( including amplifiers) that produce heat. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus. Unplug this apparatus during lightning storms or when unused for a long time. Always disconnect your entire system from the AC mains before connecting or disconnecting any cable, or when cleaning any component. This product must be terminated with a three conductor AC mains power cord which includes an earth ground connection, to prevent shock hazard, all three connections must always be used. Never use flammable or combustible chemicals for cleaning audio components. The decoding circuit We adopted the latest digital technology, making use of the Delta digital interface which was developed independently by Xindak to upgrade the signal from 16Bit/44. 1KHz to 24bit/96KHz and then accomplish 24Bit/96KHz decoding. Multi-linear power supply circuits We adopted audiophile-level linear power supply circuit. The independent voltage regulating and filtering for each power supply improve the sound quality greatly and make the sound more exquisite and transparent. The two custom-made high quality annular power transformers and independent power supply system on digital and analog parts could greatly reduce the mutual interferences and make the sound purer. We use the advanced CAD technology, Two-sided hole-drilled glass and fiber plate which has excellent high-frequency characteristics and many grounding wires for shielding to reduce various disturbances and improve the Signal to Noise Ratio. 3 XA6950 Chapter 3 3. 2 Block Diagram Introduction U11 DIGITAL TO ANALOG CONVERTER 3. 3 Front panel Digital to Analogue Converter DAC-3MK 1 2 3 4 1 Power Button: Press this button, this unit will be switched on.
