Overview

For audiophile users, the playback of digital music sources and the associated conversion of the digital signals into high-quality analogue signals is an absolute must. To meet these demands, the ASUS Xonar team presents the Essence One MK II external sound card. The Essence One MK II combines several functions in one device. It is, on the one hand, a digital-to-analogue converter (DAC) with audiophilic sound quality, which can play digital music in the best quality from the PC via USB.

Details

On the other hand, it also fulfills this task as a stand-alone version without a PC. Via the coaxial or Toslink connection, for example, CD / DVD / Blu-ray players can be connected to play music in the best quality. Last but not least, the Essence One MK II acts as a high-end headphone amplifier especially for very high-quality headphones with an impedance of up to 600 Ohm. With its 8x symmetrical upsampling, an extremely high noise-to-noise ratio of 120dB and interchangeable operational amplifiers, the Essence One MK II is the best high-end USB digital-to-analog converter.

The features of the ASUS Essence One MK II at a glance:

Digital-to-analog converter (DAC) with audiophilic sound quality
Stand-alone function without PC: coaxial and Toslink connection for CD / DVD / Blu-ray player
Headphone Amplifier for very high quality headphones with an impedance up to 600 Ohm
Extremely high signal-to-noise ratio of 120dB
8x symmetrical upsampling
The Essence One MK II external sound card supports balanced XLR outputs, which can be used to transmit audio signals symmetrically. The symmetrical signal transmission is currently used almost without exception in professional sound engineering. It prevents unwanted interference and interference from the outside and thus offers a higher quality sound experience. The transmission of electrical audio signals can be interfered with by external influences such as, for example, the inductive influence of alternating current carrying cables (power cables).

In order to prevent this, a symmetrical signal transmission is used instead of a two signal transmission conductor. On the second line, the identical signal is transmitted as on the first, with the same impedance but opposite polarity. Since a disturbance has the same effect on both signal conductors, the difference between the two signals, as soon as they reach the target, is almost mutually exclusive. Thus, balanced lines are perfectly suited for professional applications, where interference can lead to degradation of the signal quality, especially with long cable connections.

By "upsampling" is meant the increase in the sampling rate, i. The conversion of a digital signal with a low sampling rate to a digital signal with a higher sampling rate, the signal information being maintained completely and unchanged. The Essence One MK II gets despite every Upsampling while playing a piece of music from the user's music collection every sound detail.

While traditional USB DACs increase the sampling rate of various audio sources without considering their differences to 192kHz, the Essence One MK II increases 44.1 / 88.2 / 176.4kHz signals to 352.8kHz and 48/96 / 192kHz signals to 384kHz And all this symmetrically. To increase the data volume, the Xonar Essence One also increases the bit rate according to the original content up to 32bit. (44.1 * 8 = 352.8kHz, 48 * 8 = 384kHz)

The average noise margin of conventional USB DACs is about 110dB. With its extremely high signal-to-noise ratio of 120dB, the Essence One MK II allows much cleaner sound, maintains all the sound details and reduces the noise level significantly. The Essence One MK II has a first-class headphone amplifier that boosts any Hi-Fi headphone with 100% sound, even at high impedance of up to 600 ohms. The headphone amplifier offers high dynamics, fine sound details and low distortion.

An OpAmp (operational amplifier) is the central component of a DAC. It amplifies the analog signal and influences the sound character (darker, brighter, sound image, etc.). The ability to exchange OpAmps and use almost any OpAmp instead, makes the Xonar Essence One absolutely unique among all high-end USB DACs and offers the user the possibility to customize his sound image.

The internal power supply supports all international voltages and has generous clearance for overvoltage and undervoltage conditions. It offers the purest current for the purest sound and an excellent shield against interference frequencies caused by the power cable.

The ASUS Essence One MK II is equipped with two dedicated manual volume controls on the front: one for the headphones and one for the speakers. In contrast to conventional USB DACs, which only have a control for the output power of both headphones and loudspeakers or no volume control at all, the user can set the volume for headphones and loudspeakers separately for the Essence One MK II.

The ASUS Essence One MK II is equipped with a series of digital inputs, both coaxial and Toslink, for connecting digital sources. The digital inputs also support data formats with sampling rates of up to 192 kHz.
