Balanced XLR output: 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 the professional applications for long cable connection which 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). Internal power supply: The internal power supply supports all international voltages and has generous margins for over and under voltage conditions. It provides cleanest power for cleanest sound with excellent immunity to noise on the AC line. 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. Actually, 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 panel will light up.) Low Clock Jitter with Asynchronous Data Transfer: Most USB audio uses Synchronous Data Transfer mode to adjust internal clock to compensate different data transfer rate between PC and USB Audio Device. But the jitter is worse if the transfer rate is different a lot between PC and Device. Instead, ASUS Xonar Essence One supports Asynchronous Data Transfer mode. This mechanism feedbacks the buffer status to the system, and the system will base on buffer status to adjust the speed of data transfer, which leads to the low jitter in Xonar Essence One. Dedicated volume controls: ASUS Xonar Essence One is fitted with two dedicated Volume Controls specific for the output levels of headphone and speaker. Unlike most USB DACs which use only one Volume Control for the output level of both headphone and speaker (or even no Volume Control), Xonar Essence One allows users to set the headphone and speaker volume level separately. Toslink and Coaxial S/PDIF inputs: ASUS Xonar Essence One is fitted with one 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. 12 ASUS Xonar Essence One
