4. nel will light up Din cota Windows Audio engine Low Clock Jitter with Asynchronous Data Transfer Most USB audio uses Synchronous Data Transfer mode to adjust the internal clock to compensate different data transfer rates between PCs and USB audio devices But the jitter is worse if the transfer rate is different between a PC and the audio device To avoid this issue the ASUS Xonar Essence One supports Asynchronous Data Transfer mode This mechanism feedbacks the buffer status to the system and the system is based on buffer status to adjust to the speed of the data transfer which leads to a low amount of jitter in the Xonar Essence One Dedicated Volume Controls The ASUS Xonar Essence One is fitted with two dedicated volume controls one for the headphones and another for speakers Unlike most USB DACs which use only one volume control for the output level of both headphone and speaker or even no volume control The Xonar Essence One allows users to set the headphone and speaker volume level separately Toslink and Coaxial S PDIF inputs The ASUS Xonar Essence One is fitted with a set of digital inputs Coaxial and Toslink which enable the connection of source components The digital inputs accept data formats at sample rates up to 192 kHz Specifications Output Signal to Noise Ratio A Weighted Front out 120 dB Output THD N at 1kHz Front out 0 000316 110 dB Frequency Response 3dB 24bit 192KHz input
5. swap almost every OP amps for a fully customized sound Op amp Cleanest sound thanks to a dedicated internal power supply The internal power supply supports all international voltages and has generous margins for over and under voltage conditions It provides the cleanest power for the cleanest sound with excellent immunity to noise on the AC line Balanced XLR output The Xonar Essence One also features balanced XLR outputs This is a higher quality output that is useful for eliminating unwanted noises and interference Since a balanced line contains two signal carrying conductors of equal magnitude but opposite polarity noises induced along the cable path cancel each other out when they reach the destination load This makes balanced lines perfect for professional applications where long cable connection with induced noises might be a problem XLR connectors should be wired as follows Pin 1 Ground Pin 2 Hot in phase Pin 3 Cold phase inverted Bit perfect with ASIO 2 2 Driver Bit perfect is how the audio stream will come from your PC If you are running bit perfect with ASIO you will hear the music as it was encoded on the CD The ASUS Xonar Essence One s ASIO 2 2 driver simplifies the process of multiple audio streams bypassing latency issues in Windows to deliver a low latency high fidelity sound file that is identical to the original audio file PS When you run bit perfect the BIT PERFECT LED in the front pa
