1.5 Power and Safety Information
This symbol, located on the equipment and in this manual, refers to important instructions. Read this
manual thoroughly before operating this equipment.
To prevent fire or shock hazard, do not expose this equipment to rain or moisture. Do not block any of the
ventilation openings. Do not defeat the safety purpose of the grounding-type plug. A grounding type plug has
two blades and a third grounding prong. The third prong is provided for your safety. If the provided plug does
not fit into your outlet, consult an electrician for replacement of the obsolete outlet. Protect the power cord
from being walked on or pinched, particularly at the plugs, convenience receptacles, and the point where they
connect to the Aurora
(n)
. Unplug this device during lightning storms or when unused for long periods of time.
Aurora
(n)
utilizes a state-of-the-art universal power supply. The power supply will auto-detect the voltage from
100V to 240V and conform appropriately. No manual voltage adjustment is necessary.
1.6 Rack-Mounting
The Aurora is able to be mounted in standard studio equipment racks. Please note that high performance, high
resolution A/D and D/A converters generate substantial heat. The amount of generated heat increases with
channel count and sample rate. 8 channel units running at 44.1kHz or 48kHz will generate very little heat
while 32 channel units running at 192kHz will produce more heat. For optimal performance and product
longevity, it is recommended to leave an empty rack space above and below the Aurora
(n)
.
1.7 Operation Requirements
To operate Aurora
(n)
successfully with your existing equipment, first let’s verify that you have compatible
elements for best results.

Aurora
(n)
PHONES outputs are suitable for driving stereo headphones through a ¼” TRS connection. Any
standard set of headphones should work with the Aurora
(n)
.
The Aurora
(n)
’s Analog I/O can operate with balanced or unbalanced, line-level analog audio equipment
(power amps, powered speakers, headphone amps, microphone pre-amps, mixing boards, etc.). The default
TRIM level is +4 dBu (+20dBu = 0dBFS with 16dB of headroom), and can be toggled to consumer level of -
10dBV in banks of four channels. Aurora
(n)
analog I/O uses industry-standard D-Sub connections and can be
used with Lynx branded D-Sub to XLR cable sets, or third-party cable sets with whatever connector types are
required.
Aurora
(n)
’s word clock connectors use industry-standard BNC connectors and works with standard 75 Ohm
word clock cables.
1.7.2 Computer requirements
Aurora
(n)
is configured to operate with Mac or PC computer systems via USB, Thunderbolt, ProTools|HD
(DigiLink) or Dante (Ethernet). Check the system requirements below to ensure compatibility with your
platform and format.
It also is important to note that most professional audio applications place significant demands on your
computer’s resources, and it is therefore recommended that you meet or exceed the recommended system
requirements for your Digital Audio Workstation or audio playback software, which will likely be greater
than those listed for Aurora
(n)
. Please refer to your audio software’s documentation for more information.
