Page 4: Introduction
Unlike most standalone pro audio converters, the Aurora provides 8 or 16 channels of AD and DA conversion with sample rates up to 192kHz. The Aurora provides the essential front-end for your digital audio workstation, digital mixer, or modular recording device. -
Page 5: Features
The Aurora firmware can be programmed via a connected Lynx audio interface, infrared or MIDI. 1.2 Features 16-channels of Analog-to-Digital and Digital-to-Analog conversion. Aurora 8 8 -channels Support for 44.1, 48, 88.2, 96, 176.4 and 192kHz sample rates. -
Page 6: In The Box
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. -
Page 7: Remote Control
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... -
Page 8: Operational Overview
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 Aurora 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. - Page 9 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 button controls the standby state of the Aurora. When the front panel LEDs are not lit, the Aurora is in standby mode. In this state the Aurora is not functional and is using a minimal amount of power. To completely power down the Aurora, it must be unplugged from the AC power source. -
Page 11: Back Panel Connections
In ON mode, when AC power is applied the Aurora will be ready to use. ON is the ideal setting when a single power switch is used to turn on an equipment rack. To activate, hold the POWER button while connecting AC power. PLEASE NOTE: After the mode is changed the unit must be put into standby mode to save this setting before power is removed again. - Page 12 Section 2.4 Cable Connections for more information about compatible cable sets. LSLOT EXPANSION PORT Port for installation of LSlot or LStream expansion cards, used for expanding Aurora's interface options. Currently, the LT-ADAT expansion card is available to provide ADAT Lightpipe I/O. Other formats will be available soon.

Page 13: Cable Connections
2.4 Cable Connections Compatible cables for the Aurora analog and digital I/O ports are available directly through Lynx. The 25-pin D-Sub connectors on Aurora conform to industry-standard pin configurations, so that off-the- shelf cable solutions are available from third party suppliers should custom lengths or connector types be required. -
Page 14: Clock Settings And Connections
Whether you designate the Aurora as the clock master, thereby slaving all other devices to the Aurora, or slave the Aurora to another clock master, it is important that only a single device act as clock master, to prevent the occurrence of audible digital errors. -
Page 15: Aurora As Clock Slave
2.6.2 Aurora as Clock Slave The Aurora can synchronize to sample clock from a variety of external sources. In order to establish the Aurora as a clock slave, the correct clock source must be specified and the appropriate physical connection made. A two-stage phase-lock loop system is used to generate a high-frequency PLL clock while attenuating jitter in the selected sample clock source. -
Page 16: Synchrolock
SynchroLock provides clock synchronization while insuring bit-perfect digital transmission. When the Aurora is connected in an AES/EBU daisy chain, SynchroLock acts like a jitter firewall to prevent the propagation of jitter to downstream devices. -
Page 17: Common Studio Setups
In this example, the Aurora is configured as the sample clock source, with the mixer slaving to the Aurora via the AES connection. Since there is no computer being used in this context, settings are implemented from the Aurora front panel or external remote control via IrDA. -
Page 18: Clock Settings
3.1.1 Clock settings To use the Aurora as the clock master, select “INT” as the SYNC SOURCE from the Aurora front panel. Also, select the appropriate sample rate for your project. Make sure and only choose sample rates supported by your mixer. -
Page 19: Aurora 16 In Computer Recording System With Aes16
For this example, we will have the AES16 be the clock master, and the Aurora 16 slave to the clock coming in to the Digital input. This arrangement allows great flexibility since the AES16 will respond automatically to sample rates requested from software, avoiding the need to manually establish sample rates that match the current project rate. -
Page 20: Clock Settings
3.2.1 Clock settings Clock settings should be established from the Lynx Mixer and the Aurora front panel. The Aurora should be SYNC SOURCE set to “AES A”. When a sample rate is chosen from the AES 16 Adapter page, or when playback or recording is initiated from a software application, the corresponding SAMPLE RATE LED on the Aurora front panel will illuminate. -
Page 21: Aurora 8 In Computer System With Lynxtwo/L22
For this example we will configure the Aurora as the clock master, and have the LynxTWO/L22 slave. With this clock scheme, it would be necessary to set the Aurora to the appropriate sample rate for the audio being recorded or played. -
Page 22: Clock Settings
3.3.1 Clock settings Since the Aurora will be the master clock, the SYNC SOURCE should be set to “INT”. The LynxTWO/ L22 should have the Preferred Clock Source set to “LStream 1” in the Lynx Mixer Adapter page. Select the appropriate sample rate for your project. Remember that through LStream you can get 8-channels at up to 96kHz, but a maximum of 4-channels at rates over 100kHz. -
Page 23: Standalone Format Converter
3.4 Standalone Format Converter In addition to AD and DA conversion, the Aurora is well suited to function as a digital format converter or digital patch bay. When used with the external control software, one has per-channel control of routing from any two inputs to any output. As a standalone device, routing is global for all channels. -

AC Outlet? • Check the label by the AC adapter on the back of the Aurora to insure that you are using the correct version for your electrical system. The Aurora is available in 100V, 115V and 230V configurations. - Page 25 The selected Sync Source is flashing, and the INT LED is illuminated: If a Sync Source is chosen where a valid clock signal is not detected, then the Aurora will revert to Internal until a valid signal is present for the chosen Sync Source. To correct: •...
