4- GENERAL CHARACTERISTICS

ALP222e is a PCI EXPRESS™ x1 audio card. It can be inserted into and therefore operate in PCIe® x1, x2, x4, x8 or x16 slots.

4.1 Main hardware characteristics

• 2 balanced analog inputs (can be used unbalanced) with software-adjustable analog gain and a maximum input level of +24 dBu.
• 2 electronically balanced analog outputs, with a maximum output level of +24 dBu. (Electronically balanced outputs can process either balanced or unbalanced lines without loss of level).
• 1 stereo AES3 digital input, 32 kHz to 192 kHz, with high quality hardware sample rate converter (SRC).
• 1 AES11 synchronisation input (up to 192 kHz)
• 1 AES3 digital stereo output (up to 192 kHz)
• 1 mini jack stereo headphone output, which replicates the analog outputs.
• 1 word clock input/output (up to 192 kHz)
• 2 GPI dry contacts and 2 GPO relays
• Inter-card synchronisation

4.2 Main software characteristics

• Low latency multi-card drivers
• Wasapi/DirectSound and ASIO application programming interfaces under Windows, and Alsa and libgpio for Linux
• Simultaneous acquisition and playback in PCM (8, 16 and 24 bit), Float IEEE754
• On-board mixing of physical audio inputs and software "playback" devices to physical audio outputs and software recording devices.
• "ALP-X Manager" application installed with the driver, to control the card settings:
• clock source
• frequency of the fallback internal clock
• input and output gains, RMS VU-meters with peak-meters
• routing of inputs to outputs
• API for implementing the management of the card settings in a software application.

4.3 Routing audio streams in the card

The ALP card incorporates an on-board mixer in an FPGA component. This is a mixer with 8 mono inputs (4 stereo) and 8 mono outputs (4 stereo).

The mixer captures the 4 physical input channels of the card (2 analog channels and 2 AES3 channels) and the 4 channels of the playback devices.

The mixer restores 8 audio channels, respectively to the 4 physical outputs of the card (2 analog channels and 2 AES3 channels) and the 4 recording device channels.

The mixer can therefore be configured to perform the mixing and the routing of the 8 input channels to the 8 output channels (8 mix sums).

5.1 Required hardware configuration

There are no particular hardware restrictions in terms of PC on using the ALP card and its driver. The PC can have standard height or low profile PCIe card slots. The ALP card can in particular be used in 2U racks or reduced size PC, by using the smaller bracket instead of the standard height bracket that is fitted by default.

A PCI EXPRESS™ (PCIe®) x1, x2, x4, x8 or x16 slot must be available to plug in the card.

The processor power and memory required depend mainly on the operating system and the applications used on the PC.

The sleep mode for the PCIe bus must be disabled.

Go to Windows Settings, System, and select "Power & sleep".

Select Never" for the option "Put the computer to sleep".

On the same window, click on "Additional power settings".

5.2 Necessary software configuration under Windows

ALP222e operates under Windows from 64-bit versions of Windows 10 (from version 20H2).

To use your ALP-X card, you must install the driver included in the installation kit "ALP-X Kit" (Download the latest version from the digigram website from the ALP222e card support page).

The "ALP-X Kit" installer is used to install the following components:

• a WDM driver offering the WASAPI and DirectSound application interfaces,
• an ASIO driver, with its "ALP-X ASIO Settings" configuration interface. Installing this component is optional,
• the "ALP-X Manager" application, which serves to adjust the ALP-X card settings and display the signal levels. Installing this component is optional.

5.3 Necessary software configuration under Linux

ALP222e operates under Linux from the 64-bit Kernel 4.1x onwards.

The Alsa driver for Linux is available for downloading. It is supplied as a DKMS package, which can therefore be used to compile the driver for the target Linux distribution used.

6- HARDWARE INSTALLATION

Given the shortened length of the PCI EXPRESSTM connector and the resulting lack of mechanical stability, we strongly advise against transporting the cards installed in a computer, unless it has a device for holding the card firmly in place to avoid material damage.

The card must be inserted in the computer before installing its driver.

6.1 Preparing the card

Before fixing the card in the computer, make sure you install on the card the bracket matching the PCIe slot into which it is going to be inserted.

To install the card in a low profile PCIe slot, remove the standard height bracket by loosening the two screws on the sides of the cable connector, position the low-profile bracket and retighten the two screws.

6.2 Installing the card

Insert the card in the available PCIe slot and press to position it firmly.

Tighten the screw fixing the bracket to the chassis or lock the card using the device provided for this purpose on your computer.

6.3 State of internal LED

The ALP card has two internal LEDs on the top channel strip. The state of these LEDs can be seen when the PC cover is open.

If the card and its on-board firmware are initialised correctly, LED 1 must be lit solid green, and LED 2 must flash every second (1 Hz).

If LED 2 flashes faster (twice per second - 2 Hz), this means that the firmware version that has been uploaded to the card is corrupted, and the card is running the backup factory firmware version. It is then necessary to re-install the appropriate firmware version.

7- SOFTWARE INSTALLATION UNDER WINDOWS

IMPORTANT

To install the software, you must have administrator rights on the computer.

Please visit the Digigram website at www.digigram.com to obtain the most recent driver.

Should you use a specific application developed or installed by a Digigram partner, this may mean using a specific driver version. In this case, confirm with your application supplier which driver version to use.

Any driver downloaded from our website has to be unpacked before installing it. Double click on the downloaded file to start the auto-extraction utility. You can choose the default destination (temporary Windows folder) or select another one.

7.1 Very first installation

• Switch off the computer and insert the ALP-X card in an available PCIe slot.

Some software programs may have been designed with the ALP card settings controls built in. In this case, it may be recommended not to install the ALP-X Manager application. -ALP-X ASIO Settings: this application is used to configure the ASIO driversettings. There is no need to install it if no application reliant on the ASIO interface is used.
	The driver is installed by default in the folder "C:\Program Files (x86)\Digigram\ALP-X". To change this folder, click on Browse and select a new destination. Click on Install to continue with the installation.
	The driver and selected components are being installed.

7.2 Updating the driver version

If a driver version for the ALP card has already been installed, and you want to install another version, first uninstall the current driver version (see chapter "Uninstalling the driver under Windows"), and then install the new version by double clicking on the driver installation file "ALP-X Kit vxx.exe" (see the detailed procedure in the hereinabove chapter "Very first installation").

7.3 Updating the firmware

The ALP card on-board firmware may have to be upgraded, and updates can be supplied by Digigram and prove necessary.

Updating the firmware can be done from the ALP-X Manager GUI (see chapter CONFIGURING THE CARD UNDER WINDOWS VIA THE ALP-X MANAGER APPLICATION).

7.4 Verifying the card installation

Once the driver and card have been installed as per the process described hereinabove, you can verify that the card is installed correctly and working properly.

7.4.1 Presence of playback and recording devices

The audio devices exposed by the card driver are visible on the Windows sound panel. To open it, right click on the loudspeaker icon in the Windows taskbar and select "Sounds":

The audio devices exposed by the card driver are visible from the "Play" and "Record" tabs.

If the card devices are not listed in the Windows sound control panel:

• Make sure that the card is inserted correctly in the PCI slot and screwed to the computer chassis.
• Try to uninstall the ALP-X Kit (from the Windows control panel, Applications) and re-install it.

Playback to a device can be tested by right clicking on it and selecting "Test". The VU-meter must then show modulation and the sound must be heard on the card output(s) according to the routing and levels configured in the ALP-X Manager application.

Note

The output WDM device level setting, accessible from the Windows Sound control panel, is coupled to the corresponding input level setting of the card's onboard mixer, and impacts left and right channels.

Note that after the first installation of the card, the default gain settings are as follows:

• Input analog gains are set to 0 dB (+24 dU -> 0 dBfs).
  ●Digital input and output gains are set to 0 dB

7.4.2 Card detected by the Digigram ALP-X Manager application

The ALP-X Manager application, installed with the driver, is used to control the ALP card settings via a graphic interface. This application can be launched from the shortcut created on the desktop or from the start menu, Digigram group. The card must appear as below if it and its driver are installed correctly. Note that a maximum of eight ALP cards can be displayed and handled in ALP-X Manager.

7.4.3 Card availability under ASIO

If the ASIO driver for the card has been installed (option to be selected during the installation procedure), then the card must be detected and displayed in the ASIO control panel.

This control panel can be started from the menu , , , .

All cards present must be listed in the "ACTIVE CARDS GROUP" selection list.

9- CONFIGURING THE CARD UNDER WINDOWS VIA THE ALP-X MANAGER APPLICATION

This application can be launched from the shortcut created on the desktop or from the start menu, Digigram group.

When the application is launched, the window below is displayed and shows all the ALP cards installed in the PC.

If another view is displayed, click on the icon to display the list of ALP cards present and detected.

The following settings are displayed for each ALP card detected:

-its serial number,
- the PCIe slot row in which it is installed,
●the on-board firmware version,
●the size of buffers exchanged between the driver and the card
•the card locator

The card locator can make the LED on the card bracket flash in a certain way to identify its slot visually. It flashes for a few seconds. It is especially useful when several ALP cards are used in the same machine.

Click on the 📄 button to activate the card localisation. It then changes to red 🙏 for a few seconds (specific LED flashing duration) then goes out (end of LED flashing).

9.1 Sampling clock management

Click on the clock icon to display the clock selection settings of cards present.

The ALP card can be configured as an internal clock or external clock (AES11, AES3 input, Word Clock).

To select the clock source, click on the "Prioritized source" selection list and select the desired source.

A red padlock icon on the right of the clock name means the clock signal is absent. A green padlock icon on the right of the clock name means the clock signal is present.

In addition, the detected sample rate of an external clock is displayed in the clock list.

If the internal clock is selected ("Internal"), select the sampling Rate value from the "Internal Sampling Rate" selection list.

Possible values are: (in kHz)11.025, 16, 22.05, 24, 32, 44.1, 48, 64, 88.2, 96, 128, 176.4, 192, and Application.

Selecting "Application" means that the sampling frequency is set by the application.

Setting the card to one of the frequency values means that a software application that uses the card must be configured at the same frequency value.

Ifanexternalclockisselected, the card is synchronised to it as long as it is present.

If the external clock signal is lost, the ALP card falls back to its internal clock, which is automatically set at the same frequency as the external clock.

The clock source used at a given moment is displayed in the "Sync Source" field, and its frequency value is given by the "Sampling Rate" field.

9.2 Managing input and output levels

Note that after the first installation of the card, the default gain settings are as follows:

• Input analog gains are set to 0 dB (+24 dU -> 0 dBfs).
  ●Digital input and output gains are set to 0 dB
• The 8x8 routing matrix is configured this way:
• Play 1-2 routed to outputs 1-2
• Play 3-4 routed to outputs 3-4
• Inputs 1-2 (analog) routed to Rec 1-2
• Inputs 3-4 (AES2) routed to Rec 3-4
  The other routing points of the matrix are muted.

Click on the

icon to access the "I/O Monitor" view which is used to adjust audio levels.

The onboard mixer features two categories of audio inputs and audio outputs

●Physical inputs (analog and AES3)
- Software playback inputs. They correspond to the playback devices exposed by the driver to the applications.
●Physical outputs (analog and AES3)

- Software recording outputs. They correspond to the recording devices exposed by the driver and captured by the applications

The software playback inputs are displayed when the "PLAYBACK" button is activated.

The physical outputs are displayed when the "OUTPUTS" button is activated.

The software recording inputs are displayed when the "RECORD" button is activated.

The following table lists the various possible settings from the mixer view.

	Click on this icon to display the concerned pair of channels as two mono channel strips.
	Click on this icon to display the concerned pair of channels as one stereo channel strip.On a stereo channel strip, the controls (volumes, solo, mute) are applied to the left and right channels.
	Channel strip nameClick on the channel strip name and enter a new name.Note: when a channel strip display is changed from mono to stereo, or stereo to mono, the channel stream name goes back to the default name.As a consequence, it is recommended to keep the display mode used (mono or stereo) when the channel strip names have been changed.
	Analog input gain settingsThe analog input gain can be adjusted thanks to the potentiometer at the top of the analog input channel strip. Note that if the inputs are displayed as a stereo input, the gain adjustment applies to the left and right channels.There are three ways of adjusting the input gain.1) Click on the round potentiometer without releasing and move the mouse left or right to decrease and increase the gain respectively, insteps of 0.5 dB.2) Press the Ctrl key without releasing and then click on the potentiometer with the mouse. The gain can be adjusted in steps of 1 dB with the mouse wheel as long as the Ctrl key remains pressed.3) Click on the gain value displayed below the potentiometer, write and enter the new value.Double click on the potentiometer to reset the analog gain to 0 dB.Analog input gain values range from -88 dB to +39 dB, in steps of 0.5 dB.Here are a few examples of input level alignment:Gain=0 dB: +24 dBu->0 dBfs.Gain=+ 10 dB: +14 dBu->0 dBfsGain=+ 39 dB: -15 dBu->0 dBfsGain=-10 dB: +24 dBu->-10 dBfs
	Digital gain settingsDigital gains are available for all the input and output audio streams, and can be adjusted via the faders.There are three ways of adjusting the digital gain.1) Click and hold the fader button down and move the mouse vertically to increase/decrease the gain in 0.1 dB steps.2) Press the Ctrl key without releasing and then click on the fader button. The gain can be adjusted with the mouse wheel in 1 dB steps as long as the Ctrl key remains pressed.3) Click on the gain value displayed below the fader, write and enter the new value.Double click on the fader to reset the digital gain to 0 dB.Digital gain values range from -90 dB to +12 dB, in steps of 0.1 dB.
	Each Vu-meter displays the input signal level in dBfs, before the digital gain, or after the digital gain.Double click on the Vu-meter to display the Pre/Post digital gain selection.
	The Vu-meters display the levels in RMS or in peak-meter.The clipping threshold can be selected. When the signal level exceeds this threshold, the red LED above the Vu-meter lights up.
	SoloThe solo button has an effect on the two channels of a stereo pair.A click on this button sets the two channels in solo mode, and it turns yellow.
	MuteThe mute button has an effect on the two channels of a stereo pair.A click on this button sets the two channels in mute mode, and it turns red.
	Pairing channel stripsTo set a common level for several input channel strips, validate the button on each channel strip. The gain setting on one channel strip is then applied to all the paired channel strips.
	Pre or post fader Vu-metersThe blue LED button allows selecting if the Vu-meter displays the signal level before or after the digital gain set via the fader.To select pre or post fader Vu-meter, click on the blue LED button on the right of the Vu-meter bar(s), and select the mode.

9.3 Managing the routing and mixing of input signals

The mixer can mix all or some of the input signals towards each output. Each output can therefore receive its own mix of inputs.

As in the "I/O Monitor" view, it is possible to select the inputs displayed in this matrix (physical inputs-INPUTS and/or software play inputs-PLAYBACK) and the outputs displayed (physical outputs-OUTPUTS and/or outputs-RECORD).

There are two possible matrix views:

• A complete view that shows all the mixing points. This view is displayed when the "MATRIX MODE" selector is positioned on "ADVANCED" (view displayed above).
• A reduced view which displays a sub-assembly of mixing points. This view is displayed when the "MATRIX MODE" selector is positioned on "REDUCED" (below).

    J["GPIO"] --> K["PLAY 1"]
    J --> L["PLAY 2"]
    J --> M["PLAY 3"]
    J --> N["PLAY 4"]

Each mixing point can be activated or deactivated by clicking on it (Mute / Unmute). All the hidden boxes are deactivated mixing points.

The digital gain applied to the channel can be adjusted for each mixing point. To do this, press the Ctrl key, place the mouse cursor over the mixing point without clicking and use the mouse wheel to increase or decrease the digital gain value; the gain value applied is then displayed during the adjustment.

To directly set the gain to 0dB, press the Ctrl key and double click on the mixing point.

Visually, a mixing point is a solid blue if the gain is at its maximum (+12 dB). It is circled in blue and empty if the gain is at its minimum value (-90 dB).

Caution:

Moving from "ADVANCED" view to "REDUCED" view deactivates certain mixing points. If gain settings have been configured on these points in the "ADVANCED" view, these settings are lost when moving to "REDUCED" mode. The message opposite warns the user. Select Yes to confirm the move to REDUCED mode.

As an example, the matrix below allows the following:

- Routing the audio stream played by an application: playback channels 1&2 routed towards analog outputs 1&2, and playback channels 3&4 routed towards the AES3 output.

- Routing the physical input signals towards the corresponding outputs (ana IN 1 towards ana OUT1, ana IN 2 towards ana OUT2, AES 3 IN towards AES3 OUT).

As a result, playback signals and input signals are mixed to the outputs.

Note that a gain is applied to each input signal towards the output.

- Routing the content of physical inputs towards the associated recording outputs, so that an application can capture the input signals.

10- ASIO CONTROL PANEL for Windows

This control panel can be started from the menu , , , or from the shortcut on the desktop:

Active cards group/Asio channels allocation	This section is used to select the input channels and output channels that are managed by the ASIO driver and which can therefore be used by any application based on the ASIO interface.For every card selected from the "ACTIVE CARDS GROUP" list, click on the "ASIO CHANNELS ALLOCATION" button and select the channels to be used under ASIO.IMPORTANT: if channels are selected from different cards, these cards must be synchronised via an inter-card connection cable.A card that is not used under ASIO can be used from a WASAPI or DirectSound application.
	Buffer size (latency)This section is used to select the size of audio buffers used by the ASIO driver. This size is given as a number of samples and a cross-reference in duration is indicated for a sampling frequency of 48 kHz. The higher the buffer size, the higher the latency.A small buffer size can lead to breaks in audio throughput on a low-powered machine or on a machine with a high processor load.Sample sizeThis setting defines the format of samples exchanged between the application and the card driver.
	Enable Direct Monitoring ControlTick this setting to authorise an ASIO application to drive the zero latency hardware monitoring of inputs towards outputs. If an application monitors software, this causes latency between the input signal and the output signal, linked to the ASIO buffer sizes.
	Boost ASIOpriorityThis option allows the system to run the ASIO process with high priority, thereby increasing the reliability of this process. Caution, however, this can make other processes unstable.
	Audio errorsThis section is used to visualise current errors for playback and recording via the ASIO driver. Errors frequently reflect too small an ASIO buffer size for the system's possibilities. Should they occur, then the buffer size needs to be increased until there are no more errors.Sync status errors reflect clock synchro errors (AES11 external clock, WordClock or inter-card synchro).Error counters can be reset to zero by clicking on the RESET button.Lastly, a time counter displays the time elapsed since the last counter reset.

11- SOFTWARE INSTALLATION UNDER LINUX

11.1 Automatic installation

This method works on most major distributions, by using the DKMS system. After the initial installation, nothing more is needed to be done as DKMS will take care of re-building the driver every time the kernel is updated, or a new kernel is installed.

Requirements:

A package manager which supports DKMS. Most major distributions support this, please check your distribution's documentation if you are not sure.

DKMS

The kernel headers for the kernel version(s) you need

Git, if you don't use a Debian-based or RPM-based distribution

1. Download and install the driver
2. Install the dependencies
3. Download the driver package (Choose the latest .deb or .rpm package)
4. Install the driver package

11.2 Building and installing the driver manually

This method works for any Linux system, but it is necessary to apply it every time the kernel is updated, as it doesn't use any package manager to automatically rebuild the driver.

Requirements:

The kernel headers for the kernel version(s) you need

Git

Make and a C compiler such as gcc

Please refer to your distribution's documentation to install these requirements.

1. Get the source code
2. Compile the driver: Go into the src/ directory, and compile the driver by simply running make to create the file: snd-alpx.ko and snd-pcm-dmaengine.ko depending on your current kernel's configuration
3. Install and load the driver: The compilation has generated a kernel module: snd-alpx.ko.
4. Copy this/these module(s) to the kernel's module directory:
5. Run "sudo depmod -a"
6. Run sudo modprobe snd-alpx
7. Then run Ismod | grep snd to check installation of the driver
8. Run aplay -I or L to list the devices
9. Launch alsamixer

12- CONFIGURING UNDER LINUX VIA AMIXER

12.1 Diagram of the inputs towards outputs chain

The mixer inputs and outputs are numbered 0 to 7.

The DAW0, DAW1, DAW2 and DAW3 inputs are the four audio channels from the host machine (play by software on the host machine).

The ANA0 and ANA1 inputs are the two analog input channels (IN1 and IN2)

The AES0 and AES1 inputs are the two channels (left and right) of the digital input AES/EBU IN

The DAW0, DAW1, DAW2 and DAW3 outputs are the four audio channels destined for the host machine (capture by software on the host machine).

The ANA0 and ANA1 outputs are the two analog output channels (OUT1 and OUT2)

The AES0 and AES1 outputs are the two channels (left and right) of the digital output AES/EBU OUT

14.2 LED

The ALP card has four green LED: 2 LED on the PCB (only visible when the PC is open) and two LED on the bracket as illustrated in the diagram below.

LED	Description	Behaviour
LED 1	Signals when the card is initialised correctly	Constantly lit
LED 2	Signals if the card is running the last updated firmware or the backup factory firmware version.	●Flashes every 2 seconds:The card runs the last uploaded firmware version (normal behaviour).●Flashes every second:The card runs the backup factory firmware instead of the last uploaded version This last firmware is corrupted in memory and has to be applied again.
LED 3	Wordclock	●Off when no Wordclock signal is detected.●Flashes when a Wordclock signal is detected but the card is not synchronised on it●Lit when the card is synchronised to the Wordclock input
LED 4	Intrecard synchro / card locator	●Off when the card is not synchronised to another one via the inter card ribbon cable●Lit when the card is slaved to another one via the intercard synchro ribbon.●Flashes when the button “card locator” is pressed from the ALP-X Manager application.

14.5 How to use GPI's and GPO's

The two GPI's are dry contacts.

When the GPI X pin is not connected, the GPI status is OPEN.

When the GPI X pin is connected to the ground, the GPI status is CLOSED.

The two GPO's are relays, which means the contact between GPO xA and GPO xB is made when the CLOSED command is sent. GPO's support a maximal voltage of 48VDC and a maximum current of 0.5 amps.
