AES16e-50 User Manual Addendum 3
1Introduction/Features
The Lynx AES16e-50™PCI-Express audio interface is the first widely available computer audio product to
support the emerging AES50 standard (also referred to as SuperMac™). This product represents the union
of Lynx Technology’s industry respected digital interface experience, and the high-channel count, low-
jitter performance of AES50.
AES50 is capable of carrying up to 48-channels of audio from point to destination over a single Cat5 or Cat
6 data cable. With this single-cable solution and support for cable runs up to 100 meters, this is an ideal
format for live sound venues, permanent installations, or any high channel-count recording studios.
Currently, recording devices and mixing boards that support AES50 are being manufactured by Midas®and
Klark Teknik®, with more manufacturers certain to release compatible products in the near future.
The AES16e-50 includes all of the features of the popular Lynx AES16e-SRC audio interface, in addition
to AES50 support. AES/EBU I/O can be combined with AES50 I/O, providing for a versatile audio
solution.
Since the AES16e-50 is a variant of the AES16e card, this addendum will only address considerations
specific to AES50 operation. For correct operation, it is important to also refer to the AES16emanual
which is included in the Lynx Installation CD, as well as online at www.lynxstudio.com.

2Installation Procedures
The procedure for installing the AES16e-50 only differs from the AES16einstallation in that there is an
RJ45 bracket to install, and it requires somewhat more recent drivers.
2.1 RJ-45 Bracket
The RJ-45 bracket that is included with the AES16e-50 card is required to provide an external connection
for AES50 devices. The bracket requires a slot window in the computer, but does NOT require a free PCI
or PCIe slot. If your computer has a slot window that is not associated with a PCI/PCIe slot than that would
be an ideal choice.
1. Simply install the RJ45 bracket with a standard mounting screw into the selected slot window
adjacent to the slot occupied by the AES16e-50 card.
2. Use the included CAT5e 14” cable to connect the RJ45 port on the rear of the AES16e-50 to the
port on the inside of the RJ45 bracket.
Windows Driver Installation (Windows XP, Windows Vista, Windows 7)
The Windows driver installers that are compatible with the AES16e-50 utilize a simplified installation
procedure than what is described in the AES16emanual. For best results, follow these steps.

3Hardware Connections
The AES16e-50 has been designed for simplicity of set up. In most cases, integrating the AES16e-50 with
your equipment will require only a few minutes time.
3.1 Cables/Routers
The AES16e-50 adheres completely to the AES50 specification, including compatible cable types and
lengths.
Cat 5e or Cat 6 networking cables can both be used with AES50, but Cat 6 is recommended whenever
possible, especially for longer cable runs. Maximum supported cable length for Cat 5e or for Cat 6 is 100
meters
AES50 is not compatible with existing networking protocols. This means that off-the-shelf Ethernet
routers cannot be used with AES50 signals.
3.2 AES50 Cable Connections
Each AES50 port is bi-directional, with input and output streams both carried by the same connection. To
connect an AES16e-50 to other AES50 gear, simply connect a Cat 5e/Cat 6 cable from the RJ45 port on the
AES16e-50 to the AES50 port on the other gear.
Refer to section 5: Clocking; for information about correctly clocking AES50 devices to each other.
3.3 Computer to Computer connections
One intriguing use of an AES16e-50 is to send up to 32-channels of audio at a time between two
computers. This can be an ideal solution for a composer needing to transfer stems from a virtual instrument
computer into a recording computer, or for sending a confidence mix to a second machine while doing live
event recording.
This is just a matter of installing an AES16e-50 into each computer, and connecting them via Cat 5e or Cat
6 cable. Clock relationships must be established, please refer to section 5: Clocking; for more information.
3.4 Verifying connections
After connecting the AES16e-50 to a signal source, it is important to verify that a valid AES50 signal is
detected by the driver. There are two means to achieve this:
1. Open the Lynx Mixer.
•On a Windows computer, the Lynx Mixer is launched from Start > All Programs > Lynx
Studio Technology > Lynx Mixer.
•On an OS X computer, the Lynx Mixer is launched from Applications > Lynx Mixer.
2. Open the Adapter page, and check the section in the lower left labeled “Preferred Clock Source”.
The lowest available clock source to select here is “AES50”. Next to this AES50 selection is a
rectangular box. If the box contains a valid Sample Rate (i.e. 44.1kHz, 48kHz, 88.2kHz. 96kHz,
176.4kHz or 192 kHz) and the sample rate text has a GREEN background, then the AES50
connection is valid.
