1 Introduction
Thank you for choosing the Lynx Aurora 8™ / Aurora 16™ maste ring AD/DA converter. The Aurora
has been designed to provide you with the highest quality professional audio performance available,
offering unequalled Analog-to-Digital and Digital-to-Analog conversion, flexible routing capabilities,
I/O expansion options, external control functionality, and maximum channel capacity within a spaceefficient, single rack-space chassis.
Please take a few moments to read through the entire user manual. Reading the manual prior to use
will help to streamline the initial setup procedure and acquaint you with the Aurora’s superior feature
set, allowing you to quickly realize the full potential of this powerful audio tool. Keep in mind that
this manual covers the 16-channel Aurora 16, as well as the 8-channel Aurora 8. Both units are
essentially feature identical with the exception of channel count. Descriptions and information that are
pertinent only to the Aurora 8 will be marked the icon:
1.1 Overview
The Lynx Aurora is a professional quality Analog to Digital and Digital to Analog converter using
state-of-the-art components combined with a unique ability to adapt to today’s studio environment, as
well as live and remote recording situations. Unlike most standalone pro audio converters, the Aurora
provides 8 or 16 channels of AD and DA conversio n wi t h s ample rates up to 192kHz. The Aurora
provides the essential front-end for your digital audio workstation, digital mixer, or modular recording
device. Through rigorous component selection, custom firmware programming, and input from a
seasoned engineering team, the Aurora represents a level of sound quality previously available only to
devices costing thousands of dollars more, suitable for mastering and acoustic measurement and
analysis, as well as multi-channel music production.
The Aurora features 24-bit AES3 digital I/O and supports sample rates up to 192kHz through Singlewire or Dual-wire operation. Several cable options are available that allow connection to a wide array
of digital devices.
Should one need support for other digital formats, the Aurora is easily expandable through the addition
of convenient LStream™ or LSlot™ expansion cards. Currently, the LT-ADAT™ LStream card is
available for ADAT Lightpipe Optical I/O and the LynxTWO/Aurora Interface Kit for integrating an
Aurora with a LynxTWO or L22 card. Check the Lynx website for availability of LSlot expansion
options.
With exclusive SynchroLock™ technology, the Aurora provides unmatched tolerance to jitter when
synchronizing to external clocks. This makes it an ideal solution for situations where noise sources are
abundant, or where long cable runs are required. The SynchroLock output can also provide a clean
and accurate clock for other connected audio devices.
To adapt to the greatest variety of operational circumstances, several control options are available.
Front panel controls offer access to the most frequently required parameters and allow for effective,
independent operation. For use with a computer-based Digital Audio Workstation, the external remote
control software allows users to access operational parameters, view real-time level meters for all
inputs and outputs, save scenes, and route any input to any output from a convenient, easy to use
interface. To use this software, the computer must either be equipped with the Lynx AES16™, a
functional MIDI interface, or IrDA port. For live or remote recording situations, Lynx has developed a
unique software interface allowing complete parameter control via infrared from a standard Pocket PC.
Finally, the Aurora allows user-initiated firmware updates with files posted on the Lynx Studio
Technology website. Firmware updates provide new features and compatibility and can improve the
Aurora 8

1.5 Power and Safety Information
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. Th e 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. Unplug this device during lightning
storms or when unused for long perio ds o f ti m e.
Please note that the Aurora comes factory-configured for a specific
voltage range, and cannot be changed in the field. The acceptable
voltage range of the Aurora is printed on the label affixed to the top
cover of the Aurora just above the AC power inlet. Failure to connect
the Aurora to an AC power source that conforms to the requirements
printed on the label may damage the Aurora and require it to be
returned to the factory for non-warranty repair.
1.6 Rack-Mounting
The Aurora is able be mounted in standard studio equipment racks. Please note that high performance,
high resolution AD and DA converters generate substantial heat.
For optimal performance and product longevity, it is necessary to leave
an empty rack space above and below the Aurora.
1.7 Operation Requirements
The Aurora was designed to operate seamlessly with industry-standard components. Control
requirements pertain to use of external remote control software - disregard if you will be controlling
the Aurora from its front panel controls only.
1.7.1 Input/Output
The Aurora supports AES/EBU for the digital inputs and outputs, and can be used with any AES/EBU
device that supports standard sample rates between 44.1kHz and 192 kHz in single-wire or dual-wire
mode. Please refer to Section 2.4 Cable Connections for more information about available cable sets.
The Aurora’s analog I/O can be used with balanced or unbalanced line level devices operating at a
nominal trim level of +4dBu or –10dBV (switchable in banks of four channels). The analog outputs
Page 3
are capable of delivering +20 dBu signal levels, it is important to verify that connected equipment is
capable of handling these signal levels to prevent clipping or possible damage.
1.7.2 Remote Control
In addition to front panel controls, the Aurora can be configured conveniently from the Aurora Remote
Control software installed on a PC or Macintosh computer. A forthcoming Remote Control manual
will detail the software installation and operation. To use the optional Remote Control software, one
of the following conditions must be met:
Via Lynx AES16 Audio Interface: A PC running Windows 2000/XP or a Macintosh running OSX
with an installed and fully functional Rev B Lynx AES16 Audio Interface. The AES16 would connect
to the Aurora via the Lynx CBL-AES1605 cable or equivalent.
Via MIDI Interface: A PC running Windows 2000/XP or a Mac running OSX with an installed and
fully functional MIDI interface. Attach a MIDI cable from the Aurora’s MIDI Out to the interface’s
MIDI In, and the Aurora 16’s MIDI In to the interface’s MIDI Out.
Via Infrared: A PC running Windows 2000/XP with an installed and fully functional IrDA infrared
transceiver.
Via Infrared with Pocket PC: A Pocket PC running Windows CE® Operating System with an IrDA
transceiver.

2 Operational Overview
2.1 Front Panel Controls and Indicators
The Aurora allows extensive parameter selection and configuration from convenient front panel
controls. For standalone use, or in situations where computer control is not possible, it is important to
be thoroughly familiar with the front panel controls and display. If the correct parameters are not
selected, it is possible to damage connected equipment.
FRONT PANEL
(pictured Aurora 16)
q SAMPLE RATE
This button selects sample rate when the Aurora is set to Internal for SYNC SOURCE. Standard rates
from 44.1kHz to 192 kHz are available. When the Au rora is slaving to an external clock source, the
LED for the measured sample rate will illuminate. Holding the SAMPLE RATE button while
connecting AC power to the Aurora will restore all settings to the factory default state. PLEASE
NOTE: After the defaults are restored, the unit must be put into standby mode to save the settings
before power is removed.
w SYNC SOURCE
This button selects the clock source that drives the Aurora sample clock generator from the following
options:
INT Clock derived from the on-board crystal oscillator.
EXT Clock signal from WORD CLOCK input.
EXT/2 Clock signal from WORD CLOCK input running at half the desired sample rate.
Typically used with dual-wire AES/EBU devices.
AES A Clock signal from the AES I/O Port A Digital Input. Clock is derived from the first valid
AES/EBU channel.
Aurora 8 Clock signal from the AES inputs 1-4
AES B Clock signal from the AES I/O Port B Digital Input. Clock is derived from the first valid
AES/EBU channel.
Aurora 8 Clock signal from the AES inputs 5-8
LSLOT Clock signal from an LSlot/LStream card installed into the LSLOT expansion port (i.e.
ADAT, Firewire, etc.).
If no clock signal is available for the SYNC SOURCE selected, the LED for the selected source will
flash.
e SynchroLock
This LED shows the status of the SynchroLock clocking system.
Flashing Working (analyzing incoming clock signal). It typically takes one to two minutes to
achieve final lock. The Aurora can be used prior to a locked state, but the jitter reduction
is significantly enhanced when lock is achieved.
Solid Locked. Ready to use.
Page 5
No LED SynchroLock is disabled by remote control or the source is outside of SynchroLock range
and the Aurora has reverted back to the wide-range analog PLL. If SynchroLock failed
to lock, you can tap through the SYNC SOURCE options to return to the original source to
re-engage the SynchroLock clocking system.
r TO ANALOG OUT
This button selects the signal source that will be routed to the analog outputs. This is a global
selection, affecting all analog channels. Channels are mapped to directly corresponding channels (i.e.
In 1 to Out 1, In 2 to Out 2, etc.). Individual channels may be routed to specific output destinations
when the external control is used. Choices are:
ANALOG IN Signals from Analog In 1-16
Aurora 8 Signals from Analog In 1-8
AES IN Signals from Port A and Port B Digital In
Aurora 8 Signals from Port A Digital In
LSLOT IN Signals from LSLOT expansion device inputs (for instance ADAT lightpipe)
All 3 LEDs ON In this mode, front panel routing has been bypassed, and rou ting will be managed by
external control.
t TO DIGITAL OUT
This button selects the signal source that will be routed to the digital outputs. As with the TO
ANALOG OUT selection, this setting impacts all digital channels, whereas per channel routing is
possible with external control. It is possible to route digital inputs to digital outputs, allowing the
Aurora to function as a standalone digital router. Channels are mapped to directly corresponding
channels (i.e. In 1 to Out 1, In 2 to Out 2, etc.). Signal Choices are:
ANALOG IN Signals from Analog In 1-16
Aurora 8 Signals from Analog In 1-8
AES IN Signals from Port A and Port B Digital In
Aurora 8 Signals from Port A Digital In
LSLOT IN Signals from LSLOT expansion device inputs (for instance ADAT lightpipe)
All 3 LEDs ON In this mode, front panel routing has been bypassed, and rou ting will be managed by
external control.
y IR/MIDI
This LED illuminates to indicate activity from the MIDI input or IR transceiver. This could indicate
that the external control software is being used or that the firmware is being programmed via IR or
MIDI.
u PEAK METERS
These meters display the instantaneous peak level of audio being sent to the Aurora analog or digital
inputs. The intensity of the lower row of orange LEDs indicates signal strength. The upper row of red
LEDs indicate overload.
i IR Transceiver
The infrared transceiver mounted on the front panel of the Aurora provides the ability to control
parameters and view level meters and settings via handheld, laptop or desktop PC with Infrared
capabilities. The Aurora’s infrared transceiver utilizes the IrDA protocol, which provides reliable
communication at distances of up to one meter from the control device.
Infrared is a “line of sight” medium, so it is important that there are no physical obstructions between
the control device and the Aurora’s IR port. It is possible to use the IR features of the Aurora in
environments where other infrared devices are in use. The intended control device must be
programmed to control the Aurora with a unique hardware ID. This is an operation that is performed
with the external control software.
