Digital to analog converter CS8412-CP + TDA1543
Non OverSampling (NOS), Non Digital Filtering (NDF) Assembled and tested printed circuit board with the immersion gold plating the entire area of the conductors Discerning music lovers know that sound of audio system depends absolutely on all components, ranging from wire to the power supply. Many audiophiles have perfected the sound of their tube audio system by listening to the selection of components and by using the technical parameters only as a supporting data. The only components that can not be upgraded are digital-analog converters, because they contain printed circuit board with the electronic components. The proposed converter is different from the ordinary one in that it contains components that sound good for audiophiles. It has Takman resistors, the capacitors Nichikon Muse, Wima and output vintage 50s capacitors Siemens. There are also legendary chips CS8412-CP and TDA1543 that work without using negative feed back of stabilizers. This technical simplification improves musicality of the sound. The chips are inserted into sockets with gold plated contacts. All of those premium components are handwork installation on the PC board. The PCB is different from ordinary PCB in follow: - it is one-sided and has no metallized holes which blur the sound, - It is not covered with varnish or painted. Paints and varnishes makes the sound unnatural and synthetic, - there is no common bus, which occupies all available space and makes the sound muddy, - all wires of printed circuit board are plated with gold 0.9999 (99.99%, 24K) which makes sound warm and natural. Thanks to these unprecedented measures, the sound of converter is superior to the most of devices at a price of thousands dollars and the inscription on the board that says "Hipnosis" is quite appropriate. Power supply You can use any power supply, including batteries and accumulators with a voltage of 6.0V <6.5V <7.0V XP3 Pin 8: +6.5 V Pin 7: -6.5 V (common bus, GND) Analog first output The output voltage of 0.7 M RMS when connecting a digital signal corresponding to 0 dB The first output OR1/OL1 is for connecting to a tube amp that has high input impedance 300k Ohms - 500k Ohms and sensitivity of 300 mV. XP3 Pin 6: Out R1 Pin 5: Common bus, GND Pin 4: Out L1 Analog second output The output voltage of 0.7 M RMS when connecting a digital signal corresponding to 0 dB The second output OR2/OL2 is for an upgrade. You can connect Up Transformer through a capacitor 10 uF. For example Sowter 4383 or equivalent. In this case you can use an amplifier with an input impedance of 47k ohms and a sensitivity of 1V. XP3 Pin 3: Out R2 Pin 2: Common bus (GND) Pin 1: Out L2 S/PDIF digital coaxial input XP1 Connect standard RCA connector female with two wires to the contacts 1 and 2. Polarity is not important and is determined at the hearing.  Assembled and tested PCB with the immersion gold plating the entire area of the conductors
 You can connect an external clock. Just move the SW1 jumper to the upper position
