Formula D/A converter
Our exclusive Optologic decoder
Formula Dac is Aqua''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s decoder with Optologic decoding system. This conversion system uses the same multi-bit technology as La voce and La scala, but the Formula uses discrete
The R2R resistor array replaces the Burr Brown PCM1704 chip.

technology
FPGA and 4 piecesR2RElectromagnetic and current shielding are used between the array modules. This allows the digital circuit board and analog circuit parts including the clock circuit to be shielded to create a cleaner sound. Four large symmetrical R2R array modules create an unheard-of combination of excellent quality and excellent musicality in digital sources.
FormulaThe decoder does not use any digital filtering and other compromises. Instead, rely on making each circuit excellent. Digital and analog power supplies are purely discrete components, including BJT, Mosfet, Jfet and ultra-fast diodes. Passive components are not only selected components with good acoustic performance, but also have excellent quality with longevity and reliability. In addition, 6 high-quality electrolytic capacitors, tantalum, solid capacitors, bimetal MJP and other excellent capacitors are also selected. The directly coupled signal path itself does not use any capacitors, and the two output poles(One single-ended, one balanced with output cow)Using discrete BJT and JFET with metal film resistors, all electrical components have ultra-low RF noise.
