Welcome
Thank you for choosing AURALiC product. VEGA, the next generation Digital Audio Pro-
cessor, It is developed with the goal of “seeking for non-compromised sound”. With full I/O
ports and powerful functions, it will become the key component of your high-end stereo
system.
AURALiC Sanctuary Audio Processor
Sanctuary audio processor, the heart of VEGA, is based on multi-core ARM9 archi-
tecture with the calculating capability at 1000MIPS (millions of instructions per se-
cond), ideal for handling multi-channel high resolution music. VEGA supports DXD
format (352.8KS/s and 384KS/s PCM signals in 32bit) as well as DSD stream at
2.8224MHz and 5.6448MHz in native through 'DoP V1.1' transmission protocol.
Megahertz Upsampling
The internal megahertz upsampling algorithm can process and up-sample all incom-
ing PCM signals to 1.5MHz at 32bit, which not only improves the precision of the DAC,
but also creates a new Nyquist frequency for all PCM signals farther away from the
top end of audio frequency. As a result, our engineers are able to design a brand-new
analog circuit structure with larger bandwidth and faster slew rate.
Femto Master Clock
Femto master clock utilizes aerospace grade crystal oscillator, ultra-low noise linear
power supply and temperature compensation technology to generate the master
clock with extremely low jitter at 82 femtoseconds. More importantly, the phase noise
which affects sound quality a lot has been dramatically reduced to -168dBc/Hz.
Flexible Filter Mode
VEGA has six built-in filter modes and each contains several digital filters optimized
for corresponding sampling rate. These filters are developed using AURALiC's sub-
jective auditory sense and objective testing data relationship models with the goal of
optimizing the listening experience of different music in all formats.
AURALiC ORFEO Class-A Output Module
In order to drive various loads and to match with different power amplifiers, VEGA is
equipped with AURALiC's patented ORFEO Class-A module. The principle of this
module is to use a mass of small signal components with best linear characteristics.
By packing them through a thermal balance procedure and biasing the transistors
into Class-A, ORFEO achieves impressive performance with the open loop distortion
less than 0.001%.

Placement and Cabling
Placement
VEGA should be placed on a solid and stable surface with good ventilation condition. Do
not install this product near any heat sources such as radiators or other products (such as
amplifiers) that produce heat. Site the product so that its location or position does not in-
terfere with its proper ventilation. For example, it should not be situated on a bed, sofa,
rug, or similar surface that may block the ventilation openings, or placed in a built in in-
stallation such as a bookcase or cabinet that may impede the flow of air through the ven-
tilation openings.
Ventilation Requirement
VEGA dissipates up to 15 Watts of power during normal operation. It
should be installed in a space with at least one inch of clearance above,
behind and on both sides of its enclosure to provide adequate ventilation.
Avoid placing it directly above other equipment that produces heat.
Check Your AC Mains Voltage
VEGA is shipped with its mains voltage preset for operations in the destination country.
The mains voltage setting is written on the back of the unit, besides the power cord socket.
Mains voltage setting is not intended to be changed by the user. If it needs to be changed,
contact your dealer or AURALiC.
The power cord has a three-wire grounding type plug (a plug having a third pin for
grounding). It will only fit into a grounding type power outlet. If you are unable to insert the
plug fully into the outlet, contact your dealer or AURALiC. Do not defeat the safety pur-
pose of the grounded type plug.
VEGA MUST BE USED WITH CORRECT
MAINS VOLTAGE AND PROPERLY EARTHED!

Cabling
The I/O ports on the rear of the unit are shown as following:
1 Right Balanced Analog Output 7 S/PDIF Coaxial #2 Digital Input
2 Right Single-Ended Analog Output 8 S/PDIF TOSLINK Digital Input
3 Left Single-Ended Analog Output 9 USB 2.0 High Speed Input
4 Left Balanced Analog Output 10 Power Cord Socket
5 AES/EBU Balanced Digital Input 11 Power Switch
6 S/PDIF Coaxial #1 Digital Input
Please make sure to power off all units in your system before any cabling job, failed to
follow this instruction may result in permanent damage to the device and avoid any war-
ranty.
ALWAYS POWER OFF VEGA BEFORE CABLING!
Analog Outputs
The balanced and single-ended analog outputs of VEGA are individually buffered so
as to be used simultaneously, however, it is still strongly recommended to disconnect
unused ports to avoid any potential electromagnetic interference induced by cables.
The amplitude of analog outputs is adjustable with maximum level at about 4Vrms on
both XLR and RCA outputs. The output impedance of XLR output is very low at
4.7ohm so it can be used to drive almost all kinds of power amplifiers. Please pay
9
double caution NOT to short any pin of any analog output to ground.
NEVER SHORT ANY OUTPUTS OF VEGA TO GROUND!
FAILED TO DO THAT WILL DAMANGE THE UNIT
PERMANENTLY AND WILL AVOID ANY WARRANTY!
AES/EBU and S/PDIF Digital Inputs
The AES/EBU balanced digital input and three sets of S/PDIF coaxial inputs are de-
signed with individual input buffer circuit. The balanced and coaxial digital input
channels are transformer coupled to eliminate the EMI. The maximum sampling rate
supported by these ports is 24 Bit / 192 KHz.
USB 2.0 High Speed Input
The USB 2.0 Input uses asynchronous transmission mode and is buffered by
AURALiC's ActiveUSB technology to future reduce jitter effects. The USB input sup-
ports PCM signals up to 32 Bit / 384KHz as well as DSD streams at 2.8224 MHz and
5.6448 MHz through DoP V1.1 protocol. The specific driver is required for proper
functioning under Windows PC system, please refer to ‘USB Driver Installation’ on
page 13.
Power Cord Socket
We suggest you using a standalone power supply for VEGA to isolate it from other
digital source components using switching power supply for best sound quality. The
power consumption of VEGA is less than 20W, so a heavy gauge power cord is not
recommended as the weight of the power cord connector may damage the power
cord socket on the back of the unit. Please double check the AC mains voltage on the
back of the unit before connecting to the power.

Operation
The front panel of VEGA and the display of main screen are shown as following:
1 Operation Indicator 5 Special Function Indicators
2 Input Channel Indicator 6 Power LED
3 Input Stream Format 7 Rotary Switch
4 Output Volume
Power On/Off
VEGA will power on when the power switch (11 on the rear of the unit) is toggled to ‘I’
position and will power off when the power switch is at ‘O’ position.
As soon as VEGA is powered on, it will go to standby or sleep mode based on different
settings. In standby mode, VEGA will turn off most of its circuits to save energy. If sleep
mode is enabled, VEGA will only shut-down part of digital circuits, keep all analog on and
the Femto clock active. In sleep mode, you don't need to warm-up the unit every time you
use it as VEGA will stay in the best sounding condition. The Operation Indicator (1) will
display at low brightness in sleep mode to remind you the sleep mode.
