Placement and Cabling

Placement

VEGA G2 should be placed on a solid and stable surface with good ventilation. Do not install this product near any heat sources such as radiators or other products (such as amplifiers) that produce heat. Place the product so that its location or position does not interfere 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 installation such as a bookcase or cabinet that may impede the flow of air through the ventilation openings.

Ventilation Requirements

VEGA G2 dissipates up to 50 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 G2 is shipped with its mains voltage preset for operation 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 grounded power outlet. If you are unable to insert the plug fully into the outlet, contact your dealer or AURALiC. Do not defeat the safety purpose of the grounded plug.

VEGA G2 MUST BE USED WITH CORRECT MAINS VOLTAGE AND PROPERLY EARTHED!

 

Cabling

The I/O ports on the rear of VEGA G2:

AES, COAX and TOS

The maximum sampling rate supported by AES/EBU, Coaxial and Toslink inputs is 24Bit/192KHz. All input data will be buffered by the Lightning Tesla platform to removing jitter and forwarding the signal to the DAC circuit with its own Femto clock to regulate timing.

USB HS

The maximum sampling rates supported by USB HS are 32Bit/384KHz and DSD512. USB 2.0 HS uses asynchronous transmission. All PCM data will be buffered by the Lightning Tesla platform, removing jitter and forwarding the signal to the DAC circuit with its own Femto clock to regulate timing. DSD data will be buffered by separate circuit, removing jitter and forwarding the signal to the DAC circuit with its own Femto clock to regulate timing.

L-LINK (Lightning Link)

The maximum sampling rates supported by AURALiC Lightning Link are 32Bit/384KHz and DSD512. Lightning Link is the preferred connection method if you use VEGA G2 with other AURALiC products that support Lightning Link. Please use only with the cable that comes with our Processor and DAC. Lightning Link use an HDMI type of physical connector but it is neither an HDMI port nor an I2S output. Please do not attempt to connect it to any HDMI or I2S device.

ANALOG IN

The maximum signal level supported by analog input is 2Vrms. There is a 6dB gain from the internal circuit for this input channel, but there is also a bypass mode available in the system menu (no gain, volume control disabled. Signals from analog input are routed directly to passive volume control module and is not be converted into digital domain.

STREAM

VEGA G2 can works as a standalone network streamer when it is connecting to home network by Ethernet cable. The stream input supports both OpenHome and Roon Ready control protocol. Some other protocols, such as AirPlay are still under development. The maximum sampling rates supported for streaming are 32Bit/384KHz and DSD512.

RIGHT/LEFT OUT

The balanced, single-ended analog outputs of VEGA G2 are individually buffered and can be used simultaneously. However, it is recommended to disconnect unused ports to avoid potential electromagnetic interference induced by cables. The amplitude of analog outputs is adjustable with a maximum level of about 4.8Vrms for both XLR and RCA outputs. The output impedance of XLR output is very low at 4.7ohm, so it can be used to drive a wide variety of power amplifiers. Please pay special attention NOT to short any pin of any analog output to ground.

MCKIN

The MCK IN is the master clock signal input used when VEGA G2 is connected to a LEO G2 Master Clock unit. Please refer to LEO G2 user’s guide for detailed instructions.

AC Mains

For the best sound quality, we suggest using a standalone power supply for VEGA G2 to isolate it from other digital source components that use switching power supplies. The power consumption of VEGA G2 is less than 50W. 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.

Please make sure to power off all units in your system before any cabling job; failure to follow this instruction may result in permanent damage to the device and void any warranty.

ALWAYS POWER OFF VEGA G2 BEFORE CABLING!
