Questyle Q192 DAC with Headphone Amplifier silver Digital-to-Analogue converting 1.Wolfson WM8740 DAC chip, with Questyle innovative circuit design 2.4 levels of filters and voltage regulators for DAC chip 3.Specific OPA275 LPF output stage eliminates TIMD (Transient Intermodulation Distortion). 4.LPF and buffer all utilizes WIMA FKP2 capacitors are to reduce noise pollution. 5.Schottky rectifier, 9pcs Nichicon FG capacitors and 18 sets of separate regulators are utilized. Input and Output 1.Input with USB and Coaxial, 192KHz/24bit 2.Output with 6.5mm standard stereo headphone Jacks 3.Coaxial outputsupport link to other digital audio device 4.USB 3X clock structure for USB asynchronous transmission 5.The dedicated USB driver program guarantees the stability and compatibility of the whole system. Q192 DAC chipset is Wolfson WM8740, and based on it we designed our innovative circuit: 3 power regulators adopted to individually provide power for WM8740, Analogue output stage use ADI calculation amplifier OPA275 and WIMA FKP2 capacitors to reduce noise pollution. The Amplifier section is adopted Questyle patent Current Mode Amplification technology design. All the transistors are working in current mode, so it can provide 500KHz broad band range, ultra-low distortion of 0.0004%, high density, strong sense of space, and more details appearance. The output stage specially selects ultra-fast speed operation capacitors with 1A current output capacity, whose output voltage enough to drive 300ohm impedance headphone. Advanced USB Asynchronous 3X Clock structure, follows the same design as the flagship DAC model CAS192. Wolfson WM8740 DAC chipset plus Questyle innovative circuit design, it brings outstanding sound performance. Apart from the DA converting, Q192 amplification utilized our patented current mode headphone amplification technology.
