6BUsing the AES16
7.5 AES/EBU Dual-wire operation
The AES16 supports dual-wire AES/EBU
operation in which each physical input or output
connection passes a single channel AES/EBU
signal running at half the system sample rate.
This capability provides compatibility with
legacy devices that do not support single-wire
AES running at sample rates greater than 50kHz.
Dual-wire mode can be enabled independently
for inputs and outputs using the WideWire In
and WideWire Out controls on the Adapter
window of the Lynx Mixer. See Section 6.2 for
more information. When dual-wire mode is
enabled the number of available audio channels
is reduced to eight.
With WideWire In enabled, the AES16 translates
dual-wire input signals internally to input
channels of the on-board mixer according to the
first table to the right. In this mode, input
channels 5 – 8 are not active.
NOTE: Mixer Input Channel selection is
available using the Input Source select buttons
on the Record/Play window of the Lynx Mixer.
See Section 6.3. Record/Play Window
With WideWire Out enabled, the AES16
translates output signals to dual-wire connections
according to the second table. In this mode,
output channels 5 – 8 are not active.

7.6 ASIO Specific Setup
Several control parameters of the AES16 are
accessible from the ASIO Control Panel within
applications that utilize the AES16 ASIO driver.
Specific controls may vary, but most
applications offer access to buffer size, clock
selection, sample rate and number of active I/O
channels. One of the benefits offered by this
inter-application control, is that these parameters
can be saved with a project – allowing consistent
performance conditions each time a project is
opened.
For this reason, it is preferable to initiate these
settings from within the ASIO application, rather
than from the Lynx Mixer Adapter window
whenever possible.
For specific information about the parameters
available from within the most popular audio
applications, please see the application notes on
our website, at:

7.6.1 ASIO Positioning Protocol
The AES16 drivers support Steinberg's ASIO
Positioning Protocol (APP) for users that need
timecode synchronization capabilities and use an
application that supports ASIO Positioning
Protocol. In order to take advantage of this
feature, a Lynx LS-ADAT card would need to be
used in conjunction with the AES16 in order to
provide a sync source to the system. With a valid
sync source connected to the ADAT Sync In port
on the LS-ADAT, sample-accurate
synchronization is possible via APP.
