1 Introduction
Thank you for purchasing the Lynx E22 or E44™ audio interface! We have worked hard to
create a reliable and high performance audio device using the latest high-speed interfacing
technology available. We believe you will find our efforts to benefit all of your audio
projects immensely.
This manual covers operation, product characteristics, and information to help you get
started. Additional information is available via our website’s support resources. Please refer
to Section 11: Support at the end of this manual for support contact information.
The E22/E44 is a PCI Express audio interface which offers mastering quality Analog-to-
Digital, and Digital-to-Analog conversion, as well as Digital I/O. Its drivers have been hand-
coded to provide reliable operation with the widest variety of software applications and
computer configurations. The E22/E44 can be used with Windows- or Mac-based computer
systems, and is compatible with a variety of hardware expansion chassis where native PCIe
slots are not available. It includes a convenient and easy-to-use software interface for setting
parameters, managing volume levels, monitoring input signals and viewing real-time meters,
etc.
PCIe is the optimal conduit for an interface as it provides high bandwidth, low latency, and
minimal interference from Operating System processes. Well-designed PCIe interfaces are
ideal for mission critical contexts, as there is an established history of consistent up-time and
bullet proof reliability. The Lynx field programmable hardware design ensures that the E22
and E44 hardware can be updated via online firmware updates to keep the card feature rich
and adapted to the latest technologies. These upgradeable designs have been instrumental in
the legendary lifespan of Lynx audio products.
1.1 Overview
The E22 and E44 audio interfaces turn your computer into a powerful digital audio
workstation, providing both mastering-quality AD/DA conversion as well as Digital I/O. The
included Lynx Mixer application provides zero-latency monitoring, accurate metering,
adapter configuration and flexible routing capabilities. Lynx Mixer is identical for computers
running Windows or OS-X. With support for WDM and ASIO on Windows computers and
Core Audio with OS-X computers, virtually all professional audio applications can work
with the E22/E44 cards.
Up to four E22, E44 or Lynx AES16e cards can be used in a single computer. For users who
have computers without PCIe slots, these cards can be installed into a Thunderbolt expansion
chassis for seamless operation with the latest generation computer hardware.
Similar to other Lynx products, E22 and E44 incorporate an FPGA for audio mixing and
control functions that can be easily updated in the field. This flexible design improves
compatibility with future computer systems and allows for an evolving feature set.

2 Before you begin
We recommend that you read through the entire manual to acquire an overview of the
installation procedure and use of the E22/E44.
It is highly recommended that you have a good working knowledge of Windows and/or
Macintosh operating system basics and an understanding of computer hardware basics. This
information is widely available on the web and from various computer hardware and
software manufacturers.
We also strongly recommend you familiarize yourself with the basics of digital audio and
computer recording, and particularly with the basic functionality of your chosen audio
software. A solid grasp of the operational fundamentals of your Digital Audio Workstation
software and its user interface will go a long way toward enhancing your experience with the
E22/E44.
2.1 In the box
The following items are included in your E22/E44 carton:
¾ E22/E44 card in an antistatic bag
¾ Quick Start Guide
If any items are missing or damaged, please contact your dealer or Lynx at
www.lynxstudio.com.
Please note that the cables are sold separately.
2.2 Operational requirements
To use the E22/E44 you must have a computer with an available PCI Express slot. It can be
any size from x1 through x16. An alternative is an expansion chassis that accepts PCIe cards,
and connects to the computer via Thunderbolt or some other method. If considering this
route, check with Lynx Technical Support for recommendations of chassis that have been
verified with Lynx cards.
It also is important to note that most professional audio applications place significant
demands on your computer’s resources, and it is therefore recommended that you meet or
exceed the recommended system requirements for your Digital Audio Workstation software,
which will likely be greater than those listed for the E22/E44. Please refer to your audio
software’s documentation for more information. Also, installing multiple cards will place
greater demands on the host computer than the minimum requirements.

5 Installation Procedures
The procedure for installing the E22/E44 requires that you physically install the card inside
your computer before running the Driver Installer.
The Driver Installer will install the required driver files and the Lynx Mixer application, as
well as configure your system to recognize the E22/E44.
5.1 Hardware Installation
1. Turn OFF the power to your computer system and disconnect the power cords.
2. Touch a metal plate on your computer system to ground yourself and discharge any
static electricity.
3. The E22/E44 Digital I/O is set to AES by default. If you would like to switch the
protocol to SPDIF, this is done with jumpers JP701 and JP702 to set the mode, and
switch SW200 to set the format. In the case of the E44 you can switch both Digital
I/Os to SPDIF or have one be SPDIF and the other AES. Remember that both the
jumpers and switches must be altered to go from the default of AES to SPDIF. To set
the mode, refer to the graphic below for jumpers JP701 and JP702. The format is set
using SW200: Switch 1 controls Digital In/Out 1while Switch 2 controls Digital
In/Out 2 (E44 only). The ON position selects SPDIF format and the ON position
selects SPDIF format.
4. Remove the cover from your computer chassis and select an empty PCI Express slot
in your computer.
5. You should refer to your computer system documentation for any special instructions
on installing expansion cards and peripheral equipment.
6. Unscrew and remove the slot cover from your selected PCI Express slot.
7. Insert the E22/E44 into the selected PCI Express slot and press it down so that the
contacts are securely seated.

9
8. Secure the bracket of the card to the computer chassis using a chassis screw or
retaining bracket.
9. Replace the computer chassis cover and reconnect the power cord.
10. Connect the Audio and Sync cables to the E22/E44. Refer to Section 5.3: Cable
Connections for more information.
11. Install software using the installation procedure for your computer type and operating
system from the following section.
5.2 Installing the Lynx Driver
Lynx Drivers and firmware updaters are updated regularly. The most current versions can be
easily downloaded from the Lynx Website: http://www.lynxstudio.com/ > Support>
Downloads. Make sure that you choose Lynx E44 or Lynx E22 as the “Product”.
If you are updating an existing driver, the driver installation program will automatically
remove the old driver when the new one is installed. When installing drivers, make sure that
all software programs, especially audio applications, are closed.
The steps below will presume that the appropriate driver has been downloaded to your
computer.
5.2.1 Windows 7 (32-bit or 64-bit) or Windows 8
1. Locate the E44/E22 driver from your downloaded files. The file name will be
V2Setup###.exe (where ### is the version number of the driver)
2. Double-click the installation file to start the driver installation
3. Accept the License Agreement by clicking “Accept”
4. The installer will extract the necessary files to the C:\Lynx directory. Click “Extract”
from this window

10
5. If you are prompted to let the program make changes to the computer, select “Yes”
6. You will next see the driver Install dialog. Click “Install”
7. You may get a Windows Security Dialog Bog. If so, select “Install”
8. Driver installation will proceed
9. Finally you will receive a confirmation that the install completed successfully
10. The card is ready to use, no reboot necessary
NOTE: The driver installation process installs both the Windows driver and the Lynx
Mixer application. The Lynx Mixer application is installed into the Lynx Studio
Technology program group
