D100自上市以来,以足够优秀的性能,丰富的功能,合理的价格,优良的品质迎得了广大用户的认可,自上市至今,已销售一千多台,非常感谢各位的支持与厚爱.
销售同时,我们也一直在收集用户反馈信息,综合意见对机器进行调整,D100II的改进重点在调音上,经历数千小时的聆听调整, D100II声音在高素质的同时比D100更饱满,细节更丰富,动态更足.音场更宽,声音包围更强,更具有音乐味.不再是原来重素质,稍直白的声音.
D100 II在D100的基础上将USB接口集成电路更换成了可支持ASIO的 TE7022L,比原来对电脑USB端口干扰的要求降低,稳定性更好,不容易爆音.
D100 II是由钰龙韵电子有限公司精心研发的一部高精度音频解码器，它具有丰富的接口、优秀的性能、小巧的体积，可以方便的组合成个人高保真音频娱乐中心。
本机特点：
● 严谨的设计，充分的试验以及业界领先的测试器材带来非凡的效果：具有小于0.0005%的总谐波失真+噪声水平，130dB的闲置噪声，以及120dB的信噪比。
● 采用了异步采样转换（ASRC）技术，抗抖动能力强。原理是数字音频信号输入到本机后经过一个特别定做的1PPM精度，低相位噪声的时钟作参考，进行高达132KHZ的异步采样率转换后提供精确的，低抖动的I2S数据供给解码器处理，使解码的精度提高，以减少输入的数字信号对音质的影响，而大大的降低对前端的要求，配合各种质量的前端器材都可以充分发挥本机的性能。经过测试，在数字输入信号加入80ns抖动后对本机性能影响轻微，而作为对比的一个不带ASRC的DAC已经不能正常锁定而无法正常工作。
● 选用成熟可靠的模拟线路，配合经过反复测试比较之后选用的运放及其他零件，将声音调整至温暖厚实，细腻的风格。整体听感为解析力高，动态大，音场宽广。
● USB接口使用可支持ASIO ，USB2.0的TE7022L，其从USB输出的I2S信号供ASRC处理再进行解码，可达到与同轴，光纤，平衡输入相同的性能指标：总谐波失真+噪声小于0.0005%
● 具有声音风格切换的高性能耳机放大器，通过面板的Sound按键切换声音风格，默认常用模式为Sound MODE1，声音通透而动态好。切换到MODE 2则是柔和模式，适合高频比较亮的耳机，或者喜欢略暗高音的听众。
● 两组不同阻抗的耳机输出接口。低阻抗耳机接口（Low）适合高灵敏度低阻耳机，如入耳式耳塞。高阻抗耳机接口（High）适合大多数头戴式耳机，方便搭配使用各种耳机。也可以通过不同的接口得到风格略有不同的声音。
● 通过面板MODE键可以进行便捷的操作，输入通道自动记忆可以自动恢复关机前选择的通道，让您欣赏音乐变得更轻松！
● 铝合金精工细制的机壳，量身定制的高品质镀金接插件，带来精细的操作手感，优异可靠性以及稳固的连接。
● 全球通用：可以在背板选择工作电压为110-120V，或者220-240V。
输入：
本机的数字音频输入包括：光纤，同轴以及平衡接口，可连接大部分输出PCM编码数字音频信号（最高支持24Bit/192KHZ格式）的音频设备，例如CD，DVD或者声卡（某些情况下可能要特殊的连接线，例如BNC-RCA数字音频线）
而它的USB输入则可作为USB音频解码器使用，兼容Windows 7，Vista，XP，MAC OS，或者LINUX操作系统。通过面板按键切换可以选择输入设备。
输出：
本机背板的线路模拟音频输出包括非平衡的RCA接口以及平衡的XLR接口，可连接各类放大器和有源音箱；面板上的耳机输出接口可连接16-600欧姆的各种耳机。
!!!注意: 线路模拟音频输出并不受面板的音量旋钮控制，而是固定在最大电平。所连接的器材必须具有音量控制，否则可能严重损坏所连接的器材以及听众的耳朵。本公司对此一概不予负责。
如需ASIO功能，可安装D100 II专用ASIO驱动。
建议: 使用USB连接本机，将电脑系统音量调至最大，播放软件的设置改为24BIT/96K时效果更好。
Carefully designed and manufactured by ShenZhen YuLong Electronics Co. Ltd., The D100 II is a high-precision audio decoder. Thanks to it's plenty interface, excellent performance and small size, it is very convenience to integrate into your Hi-Fi system.
Based on the D100, the integrated circuit of the USB interface has been replaced by the TE7022L which can support ASIO. The part of the headphone amplifier is readjusted to the more plump sound. In comparison with the D100,it is more practical!
The Features:
● Sophisticated design, adequate test and leading test equipments ensure outstanding result: THD+N<0.0005%, -130dB idle noise and up to 120dB SNR.
● By implementation of ASRC, we have achieved an excellent anti-jitter performance. The input digital audio signal is ASRC processed to 132KHZ with reference to a custom made, 1ppm precision and low phase noise clock source. The output is an extremely low jitter I2S signal to feed into the DAC chip. That results in a very precision digital to analog convert process and not sensitive to input signal quality. So a stable result is maintained within different of front end equipment. In our test, when the input digital signal is added 80ns of jitter, this DAC can produce almost same performance as when there is no jitter added, while another DAC in comparison which is not implemented with ASRC already lost the lock to the signal and cannot work.
● Carefully designed analog circuits, together with the long time listening compared components, bring to the neutral and fine textured sound quality. In general, the DAC is high resolution, extended dynamic and with an extensive sound image.
● The USB interface uses the TE7022L (Supports the ASIO and the USB2.0), the I2S signal from this chip is sent for ASRC and DAC. It can achieve the same performance index as the S/PDIF, Optical or AES/EBU inputs. The THD+N is less than 0.0005%.
● This DAC carries a high performance headphone amplifier, and sound style is selectable by pressing the Sound button on the front panel. The default style Mode 1 is natural and dynamic. Switching to Mode 2 will result in a smooth style, which is suitable for bright headphones, or if you prefer more "dark and smooth" sound.
● Two headphone outputs with different impedance: LOW is suitable for headphones with low impedance and high sensitivity such as in ear monitor; while HIGH fits most of bigger headphones. You can also try to get a different sound style by using a same headphone in different outputs.
● Easy operation: Most likely you only need to access the MODE button on the front panel. The last used input channel is stored automatically and will resume when power up. So plug and play your music.
● High quality aluminum housing, custom made gold plated connectors result in a flawless operation, a robust connection and a superior reliability.
● No matter where you are: You can select 110/120V or 220/240 operating voltage.
Inputs:
The digital input includes Optical, S/PDIF and AES/EBU, which can connect to most of the equipments with PCM digital audio signal up to 24bit/192KHZ, such as CD, DVD or sound card.
By selecting USB mode by pushing the INPUT button on the front panel, this DAC can be used as a USB sound card, and supports WINDOWS 7, VISTA, XP, MAS OS and LINUX.
Outputs:
The unbalanced RCA coaxial line level output and the balanced line level XLR output on the back panel can connect to amplifiers or active speakers. And the Headphone output on the front panel can connect to headphones with impedance from 16 to 600 Ohms.
WARNING: Both of the RCA and XLR line level outputs are NOT controlled by the Volume knob on front panel, and as always in full output level. Any equipment connected to these outputs must has a proper volume control, otherwise might be damaged. It might harm the hearing of audience too. We are not responsible for any kind of such results.
If you want to use the ASIO, it is needed to install the special ASIO drivering program for the D100 II.
Recommendation: Uses the USB to connect the D100 II, in order to get the best result, you can adjust the volume of PC to the maximum and change the setting of the player to the format 24Bit/96KHz.
