True is best. The Questyle Audio CAS192D is the world’s first USB DAC to supporttrue DSD mode.The Questyle Audio CAS192D is an upgrade from Questyle’s previous flagship model, the “D” stands for “(True) DSD”. The Questyle Audio CAS192D is designed to process DSD files in their native format, without conversion to PCM.The Power supply section is upgraded as well. Customized Plitron toroidal trans-former, Schottky rectifiers, 22pcs Nichicon 2200uF FG capacitor, 22 groups of individual power regulators, all to ensure each section, a stable and purified power. The DAC chipset uses 4 levels of digital filter and power regulation.Furthermore, Questyle Audio’s 3X Clock USB Asynchronous transmission structure is maintained in the Questyle Audio CAS192D design. And in PCM mode, the Questyle Audio CAS192D still provides 5 switchable digital filters, in which the IIR (MP) filter eliminates Pre-Ring from pulse wave. The upsampling button is switch-able between on and off, allowing convenient sound performance comparisons. The DAC chipset is Wolfson WM8741, with an improved LPF and buffer stage, changed to DALE resistors, to achieve overall a more stable performance and more purified sound.The Questyle Audio CAS192D aluminum chassis is produced by precise CNC tooling machine. The upper cover and bottom chassis “mutual bit” structure design, provides CAS192D with stable heat, excellent control of sympathetic vibration and excellent shielding of RFI/EMI radiation.Input and Output- USB input supports 192kHz /24bit PCM and DSD mode- 192kHz/24bit Standard Coaxial, Optical input- USB 3X Clock Asynchronous transmission structure- Dedicated USB drive program ensures stable transfer and compatibility- Balanced (XLR) and unbalanced (RCA) output- Neutrik jacket for XLR outputDA section features- Wolfson WM8741DAC Chipset- Support True DSD format digital to analog converting- DAC chipset power utilizes 4 level filters and power regulators.- LPF and buffer all utilize WIMA FKP2 capacitors, providing large dynamic and powerful sound- In PCM mode it provides 5 switchable digital filters, the IIR (MP) filter eliminates the pre-ring from pulse wave.- Customized Plitron toroidal transformer- Schottky rectifiers, 22pcs Nichicon 2200uF FG capacitor, 22 groups of power regulatorsCAS192DPower CordCD-ROMUser Manual1pc1pc1pc1pc0203① Balanced output for Right Channel ② Unbalanced output for Right Channel ③ Unbalanced output for Left Channel ④ Balanced output for Left Channel ⑤ SPDIF input ⑥ Optical input ⑦ USB input, type B ⑧ AC power socket ⑨ AC power fuse⑩ AC power ON/OFF Switch0405① Standby Button.

All inputs support digital filters switchable and dual clock integral upsampling technology.The Questyle Audio CAS192D internal processor will automatically recognize the input signal sample rate, automatically update and configure it, and show it in the OLE display. This will set the user free from setup troubles.Output is provided with Balanced (XLR) and Unbalanced (RCA) two options. When The Questyle Audio CAS192D is turned on, its analog output will perform a self inspection, to ensure the whole system is in “good” status, before activating the output relay. When it’s turned off, the relay will immediately cut analog output, so as to avoid any pulse wave damage to the system.(China Intellectual Property Office Patent No. 201520211945.X )Unlike other DACs that claim DSD support, yet in actuality provide DoP (DSD over PCM), the Questyle Audio CAS192D accepts the DSD bit-stream directly from your computer, bypassing your computer’s audio processing and digital volume control as well as the Questyle Audio CAS192D’s digital filters, to provide True DSD, the way it was meant to be heard, without requiring expensive difficult to install propri-etary connectors, or as is the case with DoP breaking up the bit-stream into 16bit packets and compressing them into a PCM data-stream and then uncompressing them at the other end, buffering them, then reassembling the bit-stream so that it may be sent to the DAC as DSD, all of which requires an extreme amount of processing at both the computer end and the DAC end to perform in real time () (China Intellectual Property Office Patent No. 201520212711.5)Generated signals from piano, percussion and guitar contain a large amount pulse wave. Studies of the sound psychology indicate that our ears are very sensitive to the pre-ring of impulse wave. It makes music incoherent and unnatural. The pre-ring, brought by FIR (finite impulse response) digital filters used in traditional digital to analog conversion, can be tested and heard very easily. The Questyle Audio CAS192D has the most advanced IIR digital filter, which completely eliminates the pre-ring from the impulse wave and brings the most natural sound. dCS is an example of a company using IIR digital filter technology.Different digital filters have different impulse responses and group delay, creating different subjective listening experiences. On the front panel of CAS192D, there is a DFR button providing 5 different digital filters for user to choose. Among the five digital filters, the pulse responses of IIR and FIR are totally different. Different FIR or IIR digital filters have different frequency responses. The digital filters are switch-able based on user’s favorite.Vibrating objects in nature produce a sound wave which has similar features to the IIR digital filter. There is no pre-ring before the vibration and the vibration amplitude decreases gradually after the vibration.0809WM8741DSDPCMPCM(which invariably leads to latency, data loss, etc), not to mention a 33% increase in bandwidth requirements for the USB ports and cabling.Dual Clock Integral Upsampling1011CAS192D IIR digital filter pulse responseCAS192D FIR digital filter pulse responseTo maximize the performance of digital to audio conversion, up sampling technology is widely used in high-end digital audio. In most designs, the up sampling goes up to 192K no matter what the sample rate of the signal is. In the digital audio industry, many scholars believe that there will be some error when doing non-integral ASRC, which will cause distortion and degrade the soundquality. Being different from those designs, the Questyle Audio CAS192D has two clocks with extremely low phase noise, thus the processor automatically identifies the sample rate and makes it up integrally.For instance, a certain DAC is configured with single clock, the input data, whether 44.1K or 48K, will all go up to 192K. 48K is multiplied times 4 to get 192K; for 44.1kHz to go up to 192K, the multiples will be 4.3537... (192/44.1 = 4.3537...) which is an infinite non-repeating decimal. In this case there will be too much required computation and round-off errors. But for the Questyle Audio CAS192D, if the input data is 44.1kHz, it will be multiplied by 4 to 176.4kHz; if the input data is 48K, it will be multiplied by 4 to 192K, which can avoid those negative effects. The upsampling is ASRC, and it can avoid Jitter. On the front panel of the Questyle Audio CAS192D, there is an UPSAMPLING button for starting up or shutting down the function of upsampling, and the current state of operation will be clearly seen on the screen.The Questyle Audio CAS192D will memorize the user’s operation of upsampling.The following is the THD+N and amplitude curves for non upsampling and upsampling, working at 48K sample rate with -3dBFS,24bit data.(Blue is for non upsampling; purple is for up sampling).When the sample rate is as low as in 44.1k or 48k, the 5 digital filter options of the Questyle Audio CAS192D will be:- IIR Apodisting - IIR soft-knee - IIR Half-band - FIR Apodisting - FIR Half-bandWhen the sample rate is as high as in 88.2k, 96k or 192kHz, the 5 digital filter options of the Questyle Audio CAS192D will be:- IIR Apodisting - IIR soft-knee - FIR soft-knee - FIR Apodisting - FIR BrickwallThe Questyle Audio CAS192D will divide the user’s configuration of digital filters into high and low groups and memorize the sample rate.CAS(Computer as Source) System RequirementIn order to enjoy True DSD playback, you will need the following items:- A CAS192D- A CMA800R with a pair of high quality headphones or equivalent amplifier /speaker system.- A pair of high quality balanced (XLR) or single ended (RCA) interconnect cables. - A high quality USB 2.0 cable.- A PC running Windows XP,Vista, 7, 8 or 8.1.Setup on Windows OSStep1Connect power cord to your CAS192D and a suitable 110v/220v A/C power source.

常见问题:
1):信号输入输出接通后,通电POWER指示灯亮。

但音响没有声音?
解决:首先确定输入前级和输出后级设备工作正常,然后通电自动检测输入信号,通电检测的顺序是:光纤(D1)-同轴(D2)-AUX
a:当信号为光纤输入时:对应的蓝色指示灯D1通电常亮
b:当信号为同轴输入时:对应的蓝色指示灯由D1跳到D2,D2常亮
c:当信号为AUX输入时:对应的蓝色指示灯由D1跳到D2再到不亮
注明:当接通输入信号,发现蓝色指示灯由D1跳到D2再跳到D1,说明没有信号输入,需要检查你的输入设备工作状态是否正确
2):为什么播放的是DTS或AC3片源,而输出没有5.1效果?
解决:输出信号需要和你后级的设备一一对应
a:当输出只有左右声道和重低音有声音,而左右环绕和中置没有声音时,你只需按一下解码器前面板的5.1/2.1键,即可切换过来
b:是否真正的DTS/AC3杜比5.1声道片源,解码器只能把输出的源码音频信号进行解码,而不能把任何片源强制还原成5.1声道输出
3):当模拟立体声道输入时,输出为什么没有5.1效果?
解决:接5.1声道的效果只是左右声道分解到5.1声道,是虚拟的不是模拟的。
