6 Installation Procedure
1. Remove the AC power cord. Take the top off of the Aurora 16 or Aurora 8. There are seven large screws
plus one small screw near the center of the front faceplate.
2. Remove the LSlot Expansion Port cover above the AES I/O Ports by removing the two mounting screws.
Set these two screws aside, as they will be used to install the LT-ADAT.
3. Remove the screw from the Aurora circuit board that is adjacent to the JP1 connector and the white serial
number/barcode label. Set the screw aside for reuse.
4. Install the standoff post (included with the LT-ADAT) in this same hole.
5. Grounding yourself to the earth ground, remove the LT-ADAT from its protective static bag.
Page 3
6. Attach one end of the included ribbon cable to the 14-pin header labeled “JP2” on the LT-ADAT. Insure
that the ribbon cable is exiting the top side of JP2. Attach the other end of the cable to the LStream port
labeled “JP3” on the Aurora main board. Note: The red stripe on the end of the ribbon cable will face the
back of the Aurora.
7. Carefully route the ribbon cable underneath the LT-ADAT and inside of the standoff.
8. Secure LT-ADAT with three screws; one on the standoff and two from the back panel of Aurora. Keep
screws loose until LT-ADAT is properly aligned, then tighten snugly, but do not overtighten.
9. Plug in and power up the Aurora using the front panel standby switch. If the green LED on the LT-ADAT
lights up, proceed to step 10. If the LED does not light, unplug Aurora and check the cable connections to
and from the LT-ADAT. Then plug in and power up again. If the green LED still does not light, contact
Lynx Customer Support.
10. Remove the power cord from Aurora and reinstall the Aurora top panel using the eight screws. Do not over
tighten the small screw near the center of the front faceplate as it is easily damaged.

7 External Connections
The photo below details LT-ADAT connectors.
The LT-ADAT provides two ADAT optical inputs and outputs. They are labeled on the mounting bracket and in the
figure above. The ADAT channels corresponding to each port are as follows:
IN 1 ADAT input channels 1-8
OUT 1 ADAT output channels 1-8
IN 2 ADAT input channels 9-16
OUT 2 ADAT output channels 9-16
Connect the LT-ADAT to ADAT devices in your system using standard ADAT compatible (Tos link) fiber optic
cables. Refer to the “Optional Equipment” section at the beginning of this manual for part numbers of cables
available from Lynx.

8 Aurora Routing
After installation, the Aurora will need to be configured to send and receive signals from the LT-ADAT.
Signals from the ADAT inputs can be delivered to the analog and/or digital outputs of the Aurora, and signals from
the Aurora’s analog or digital inputs can be routed to the LT-ADAT outputs. This routing can be established
globally from the Aurora front panel or on a per-channel basis from the Aurora External Control Software. The
External Control Software can be used with a PC or Macintosh computer equipped with a Lynx Audio Interface,
MIDI Interface or Infrared transceiver. For more information, please consult the Aurora External Control manual.
Front panel routing affects all 16 LT-ADAT channels, which are mapped to directly corresponding Aurora channels
(i.e. In 1 to Out 1, In 2 to Out 2, etc.). Port 1 provides channels 1-8, Port 2 provides channels 9-16.
To route signals from the LT-ADAT inputs to the Aurora analog
outputs, select “LSLOT IN” as the signal source from the TO
ANALOG OUT selection button.
To route signals from the LT-ADAT inputs to the Aurora digital
outputs, select “LSLOT IN” as the signal source from the TO
DIGITAL OUT selection button.
When routing from the front panel, signals sent to the digital outputs
are sent simultaneously to the LSLOT outputs. To choose the signal
source to be routed to the LT-ADAT outputs, select the appropriate
source with the TO DIGITAL OUT button. Note: When “LSLOT” is
chosen here, signals from the LT-ADAT inputs will be routed to the
LT-ADAT outputs as well as the AES/EBU digital outputs.
9 Clock Settings
In any system with more than one digital device, there can be only one master clock providing synchronization to all
connected devices. Devices connected to the LT-ADAT can slave to the sample clock from the Aurora, or they can
be configured as clock masters providing sample clock that the Aurora can slave to. It is also possible to have a
separate clock source that provides clock to both the Aurora and Lightpipe device(s). The essential thing is that all
devices synchronize to a single source. Please see section 2.4 of the Aurora manual for information about available
clock settings with the Aurora.
If you choose to have the ADAT Lightpipe device(s) be clock slaves, in most cases they can be set to receive clock
from their ADAT optical inputs, or via wordclock. Even if the Aurora is configured to slave to some other clock
source, valid, low-jitter clock is presented to its Wordclock and LT-ADAT outputs. See the documentation for the
ADAT Lightpipe device to determine how to change its clock source (most devices default to Internal).
The Aurora can also slave to the clock signal from the LT-ADAT inputs. To do so, simply choose “LSLOT” with
the SYNC SOURCE button on the Aurora front panel, and make sure that the ADAT Lightpipe device is operating
off of its Internal clock.
Page 6
The figures below detail three common clock schemes:
9.1 Aurora as clock master, ADAT device sl aves to wordclock
Aurora SYNC SOURCE: INT
ADAT Device Clock Source: Wordclock
9.2 Aurora slaves to ADAT device via Lightpipe connection
Aurora SYNC SOURCE: LSLOT
ADAT Device Clock Source: Internal
9.3 Aurora and ADAT device slave to house clock
Aurora SYNC SOURCE: EXT
ADAT Device Clock Source: Wordclock

10 ADAT Channel Mapping and S/MUX
This section describes the mapping of LSLOT channels to LT-ADAT channels. This mapping varies with sample
rate since S/MUX is required to support sample rates above the standard ADAT sample rate of 48 kHz.
At 44.1 kHz and 48 kHz there is a one-for-one correspondence between Aurora channels and LT-ADAT channels.
All 16 input and output channels are available.
At sample rates above 48 kHz, the signal channel capacity (and the number of required LSlot channels) is reduced
since S/MUX utilizes multiple ADAT channels for each signal channel. Refer to the following table.
ADAT Port ADAT Channel 48kHz LSlot Channel 96kHz LSlot Channel 192kHz LSlot Channel

2 8 16
S/MUX is enabled on demand, based on the current sample rate currently selected for recording or playback.
As such, the mapping of channels will change when the sample rate changes. The user must be keenly aware of this
“automatic” re-mapping to avoid mixing and routing problems.
When the Aurora has the SYNC SOURCE set to LSLOT, the LT-ADAT cannot determine if an incoming signal is
using S/MUX. Because of this, the user must manually set the SAMPLE RATE on the front panel of the Aurora to
match the sample rate of the ADAT device.
