3 Requirements

3.1 Minimum requirements

PC with one free PCI Express slot (x1, x2, x4, x8, x16).

CPU power and memory required depend on the operating system and on the audio application used.

3.2 Software requirements

LX1616ESe and LX6464ESe require installation of the drivers included in the LXES Kit version 1.12 or

higher. This kit includes:

● a WDM DirectSound driver

● an ASIO driver

3.3 Supported operating systems

LX1616ESe and LX6464ESe cards run under Windows XP, Windows 7, Windows 8, Windows 2008

Server, Windows 10, 32-bit and 64-bit versions.

4 Hardware installation

The card has to be installed in the computer prior to installing its driver.

Installing the card

Gently plug the card in a free PCI Express slot and press it down to position it firmly. Tighten the screw

to attach the card to the PC chassis so that it does not move.

Interrupt and memory address

Hardware interrupt and addresses are automatically set up at start-up by the PC Bios.

5 Software installation

The installation of the driver package requires administrator rights on your computer.

Please visit the Digigram web site at www.digigram.com for the most recent driver.

In case you run a specific application developed or installed by a Digigram Partner, this application might

require the use of a given driver version. In this case, make sure that the updated driver has been

approved by your supplier.

5.1 Installation under Windows

● Shutdown your computer and insert your card.

● Restart your computer.

● Click on Cancel if the “Found New Hardware” Wizard appears.

● Double-click on the LXES Kit vxx.msi



icon to launch the driver installation.

● A welcome message is displayed, click Next



to continue.

● The “License Agreement” window appears: read it, and click on

“I accept the terms in the license agreement”



to approve it.

LX6464ESe & LX1616ESe user guide

● In the “Custom Setup



” window, the “Drivers for the LX6464ESe board” are displayed.

In case you do not need the ASIO driver to be installed, click on the arrow on the left of “ASIO

LX”, and select “This feature will not be available”.

By default, the WDM DirectSound driver and the ASIO driver are installed.

Click Next



● In the “Ready to Install the Program Window



”, click on Install



to start copying the files.

●In case the “Digital Signature Not Found” message appears, click on



Continue



in the

“Hardware installation”



window.

● Click on Continue



in the “Hardware installation” window.

●Once the files have been copied to your disk and the driver has been started, the firmware version of

your card will be checked against the version included in the driver package.

WARNING: if the firmware of your card requires an update, it will start automatically at this stage. The update

is recommended, it ensures optimal performances and robustness of the system. The update



MUST IN NO

CASE BE INTERRUPTED



. If you do so, the card will have to be returned to our After Sales Service.

● The “DirectSound Device Builder application” is then displayed to define the DirectSound

devices that will be used.

By default, only one DirectSound stereo device is declared (first two channels of the card). You

can declare additional devices by using the “+” button (if they are not already listed). For each

new device, enter the first channel used by this device (it cannot be used by another one), the

number of channels of the device, and the name of the device under Windows Server 2003 and

LX6464ESe & LX1616ESe user guide

XP. For more recent Windows flavours, the name of the device can only be changed from the

Windows ‘Sound’ Control Panel . A DirectSound device can be multichannel (the application

must be able to manage this type of device). For more details, please refer to the online help of

this application.

Note:



The



“DirectSound Device Builder”



application can be launched at any time once

the driver of the LX6464ESe is installed ( from



<Start>, <Programs>, <Digigram>,



). It is necessary to reboot the computer to apply the

changes.

● From the “Digigram drivers” window that is displayed, in the LX-ES tab, select the processing

granularity of the card, expressed in samples.

A granularity of 64 samples is the default value (recommended). Under DirectSound, selecting a

lower value (32) will decrease the latency, but may limit the number of devices that can be used

simultaneously without dropouts.

When using the ASIO interface, the granularity may be set to 32 samples (the ASIO driver uses

a single 64-channel device, which is much more efficient than using multiple separate devices).

For more details, please see the Control Panel online help or the “Performance



” section of the

DirectSound Device Builder, or the ASIO control panel online help.

Click on Ok



● Click on the Finish



button to complete the driver installation.

5.2 Removing the driver under Windows

● Open the Windows Control Panel and double-click on the Programs and Features icon.

● Select “Digigram LXES Kit …”



, and Change/Remove.

● Select Uninstall.

● Follow the instructions to finish removing the driver.

LX6464ESe & LX1616ESe user guide

6 How to check the installation

Once the driver and the card are installed according to the procedure described in this manual, you can

verify that the card works correctly as follows.

● Open the Digigram Control Center panel from the Start menu, Digigram group.

The LX card should be listed.

● To check that the card works fine, it is possible to play a sine signal on all the outputs of the card (64

mono outputs routed to the EtherSound channels). Select the “Diagnostics” tab.

Right click on the icon of the card, and select “Play sine”. The vu-meter reflects the audio activity. To

stop the playback, right click on the icon of the card, and select “Stop”.

LX6464ESe & LX1616ESe user guide

● To check that the DirectSound devices are well installed, go to <Control Panel>,<Hardware and

Sound>, <Sound> (Tab Playback, Recording): the declared DirectSound devices are displayed.

The first stereo device of the LX card is named LX6464ES-01.

Under Windows XP, other devices have the names defined from the DirectSound Device Builder

application.

For more recent Windows versions, the other declared playback devices are listed as “Line output”,

and the recording devices are listed as “Line inputs”.

You may change their names by right clicking on the device name, and selecting “Properties”,

“General” tab.

● For testing a DirectSound playback device, right click on it, and select “Test”. The vu-meter should

indicate the audio level that is played out.

● If the ASIO option has been selected during installation, the card is visible through any ASIO

compliant application, and through the ASIO control panel.

The ASIO control panel can be launched from the Start menu, Digigram group, ASIO ES settings.

If the card is not displayed in the Digigram Control Center panel:

● Make sure that the card is correctly inserted in the PCI Express slot, and screwed on the PC

chassis.

● Make sure that the golden tracks of the PCI Express connector of the LX card are clean. You may

use a rag to clean the connector if it is a bit dirty.

●If necessary, uninstall the driver as described in this manual, and re-install it.

LX6464ESe & LX1616ESe user guide

7 DirectSound mixer panel

The card does not dispose of digital gain. Under the Windows ‘Volume’ control panel only a ‘Mute’ is available.

8 Asio control panel

To use the card through an ASIO based application, make sure the ASIO driver option has been checked during

the installation, as described above. The ASIO driver parameters can be configured from the “ASIO ES Settings”

panel, available from <Start>, <Programs>, <Digigram>, <Digigram ASIO ES Settings>.

It can also be launched directly from the ASIO software applications, as most of them feature a “Preferences” or

equivalent menu allowing to configure the ASIO devices to be used.

Buffer size

The buffer size determines the size in samples per buffer used by the Asio driver to transfer audio data from/to

the board's Input/Output. The lower the buffer size, the lower the latency.

The range of the buffer size settings depends on the stream granularity defined in the Digigram Control Center.

You can access this parameter by clicking on the "Change DSP granularity



" button.

Note that, audio dropouts may be experienced when using very small buffer size.

It is possible to check if audio dropouts are experienced. First of all start the ASIO based application. Allocate the

ASIO channels in this application. Open this ASIO control panel, and click on the “Test” button.
