Thank you for choosing D100 II Digital to Analogue Converter, and we believe this product will bring you into a brand new audio journey. 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 Based on the D100, the integrated circuit of the USB interface has been replaced by the TE7022L which can support ASIO.
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.
● 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.
The structure is as follows:
The diagram of using: Operating instructions:
1、LCD display, shows the input, output as well as the sound mode 2、Input selection: Press to select input from Optical, S/PDIF, AES/EBU and USB. 3、Sound mode selector: Mode 1 is default setting, and switch to Mode 2 by a double press. 4、LOW Headphone output: To connect low impedance and high sensitivity headphones. 5、HIGH headphone output: To connect a normal high impedance headphone 6、Volume control: To control the level of headphone out.
Warning: Please make sure the voltage selector is set to proper position that is match the actual power supply voltage. Otherwise this DAC might be permanently damaged!
