ASUS Essence One Series
Signal Management
• 4-LayerHypergroundingwithbalanceddesign
4 layer PCB board for separating Digital and Analog signals on dierent grounds
and heat source. Not only are the analog and digital signals are on dierent layers,
it is sandwiched in between multiple ground layers to further prevent signal
interferences.
• Asynchronousdatatransfer
PC uses a dierent clock system than E3 and hence a buer will monitor the data
speed such that when the PC clock is ring too fast, this is regulated and the data
transfer feed is adjusted to slow down. This greatly improves the precision of digital
audio and provides more detail with less listening fatigue.
• 384kHz/24Bit8XUpsamplingTechnology
While common upsampling USB DACs just transfer whatever audio source to
192kHz indistinguishably, Essence One Series upsamples 44.1/88.2 /176.4kHz input
to 352.8kHz and 48/96/192kHz input to 384kHz in a symmetrical way, preserving
the originality of your music collection. It also upsamples bit-rate to 32bit
corresponding to the original contents. (Note: 44.1x8=352.8kHz; 48x8=384kHz)
NOTES:
• Samplerateisthenumberofsamplesofaudiocarriedpersecond,
measured in Hz or kHz (one kHz being 1,000 Hz). The more samples per
second (the higher the "sample rate"), the better the quality.
• Bitratemeasureshowmuchdataistransmittedinagivenamountof
time. The higher the bit rate, the higher the quality of the audio playback
and the larger the le.
• Upsamplingistheprocessofincreasingthesamplingrateofasignal.
For instance, upsampling raster images such as photographs means
increasing the resolution of the image.

• CustomResistorwithhightemperatureandheattolerance
0.1% tolerance and high tolerance for temperature changes with +/-0.5ppm/Celsius
with ultra-low noise and better stability.
• DCServotoreducingDCbiasing:
The DC servo design helps to reduce decoupling and this helps to extend bass
performance with richer and deeper sounds.
