8.2 Using LT-TB with other Thunderbolt Devices

The Thunderbolt specification allows daisy chaining of other Thunderbolt devices. Common
computer accessories like hard drives, video equipment, and expansion chassis can be
connected to the Thunderbolt daisy chain, either before or after your Lynx Interface(s). Up to
six devices can be daisy chained together off of a single Thunderbolt port. The Thunderbolt
specification also allows for a separate video stream, so that in addition to the 6 devices a
monitor can be added at the end of the chain.

8.2.1 Bus Powered Devices

Some Thunderbolt devices operate from Bus Power, where they receive adequate voltage
from the Thunderbolt connection to drive the device, as an alternative to having a dedicated
power supply. The LT-TB does support such devices, but it is necessary to connect a 12V
DC power supply to the LT-TB card prior to running such a device. The appropriate AC
Adapter is available from Lynx dealers, or directly from the lynxstudio.com website. The
part number is LYN-ACPS1000.
When connecting a bus-powered device, connect the AC adapter to the 12V DC port on the
LT-TB equipped interface that precedes the bus-powered hardware in the Thunderbolt daisy
chain. Failure to connect the AC Adapter will prevent the downstream, bus-powered device
from operating.

8.3 Application Setup

The LT-TB was designed to provide maximum compatibility with the most popular audio
and multimedia applications that use the Windows MME, DirectSound, ASIO and OS X
Core Audio driver standards. It is crucial that the applications are set up correctly for optimal
operation.

8.3.1 Windows

The Windows drivers for the LT-TB support two dominant driver models, WDM (which
include MME/DirectSound/WASAPI) and ASIO.

WDM was developed by Microsoft and is used most typically by media playback
applications, such as Windows Media Player, iTunes, Spotify, etc.

ASIO was developed by Steinberg, and was designed to address the low-latency and high
channel count needs of Pro Audio and Music Production. ASIO is an option for Audio
Production applications such as Pro Tools, Cubase/Nuendo, Sonar, Samplitude/Sequoia,
Audition, etc. These applications may also support WASAPI or DirectSound, but when the
option exists, we recommend using ASIO for the best performance.

8.3.1.1 WDM/Multimedia Applications

The Aurora/LT-TB can be used as a playback device for most popular multimedia, home
theater and consumer audio applications. Some such applications allow selection of specific
playback devices. In these cases, an Aurora output device can be selected from the
appropriate device selection menu. When output device selection is not an option, it can be
