Warning:
Electrostatic discharge (ESD) can damage several

components on the board. To avoid such damage in
handling the board, take the following precautions:

Bring the device and everything that contacts it to
ground potential by providing a conductive surface and
discharge paths. As a minimum, observe these
precautions:

• Disconnect all power and signal sources.

• Place the device on a grounded conductive work surface.

• Ground yourself via a grounding wrist strap or by holding a grounded

object.

• Ground any tool that will contact the device.

Due to the reduced length of the PCI EXPRESSTM bus connector and the
resulting lack of mechanical stability, we strongly advise against transporting
the card(s) installed in a computer, unless its chassis or case provides a
dedicated support to keep the card securely in place in order to avoid physical
damage.

CONTENTS OF THIS PACKAGE

Thank you for purchasing a Digigram VX sound card.
The package consists of the following components:

• a VX222e or VX222e-Mic sound card

• the User’s Manual at hand.

The end user version additionally includes:

• two breakout cables (analog and digital)

• a CD-Rom with drivers, installation notices, FAQs, etc…

• a registration form

For the OEM version, the cables are available optionally.

FEATURES

VX222e and VX222e-Mic are audio cards for PCI EXPRESSTM (PCIe®) bus.
They are in PCI EXPRESS

TM

x1 format and can thus be plugged into any PCIe®

slot (x1, x2, x4, x8, x16, x32).

VX222e & VX222e-Mic main hardware features

• 2 balanced

∗

analog mono line inputs, with software adjustable gain and a

maximum input level of +24 dBu

• 2 servo-balanced

∗∗

analog mono line outputs, with software adjustable

gain and a maximum output level of +24 dBu

• 1 AES/EBU

∗∗∗

stereo input

The selection of the digital input for recording excludes the selection of
the analog inputs.
It is possible to use the signal on the digital input as reference clock.

• 1 AES/EBU

∗∗∗

stereo output

Always transmits the digital version of the analog outputs 1 and 2.

• 1 LTC (Linear Time Code) input

• 1 mini jack headphone stereo output

This output is in parallel of the analog outputs 1 and 2.

• 2 General Purpose inputs and 2 outputs (GPIOs)

• Inter-card synchronization connector

∗

can be used with unbalanced signals

∗∗

electronically servo-balanced outputs provide automatic level adjustment to accommodate

either balanced or unbalanced lines

∗∗∗

can be used as S/PDIF interface as well

Additional hardware features VX222e-Mic

• 1 analog microphone input with

- high-quality preamplifier

- switchable 48 V phantom power

- analog expander/compressor/limiter
This input is mixed with the two line inputs before A/D conversion.

• 1 AES/EBU Sync input

∗

• The AES/EBU input is AES42 compatible (for connecting digital

microphone) and features a hardware sample rate converter

∗

(for details

see chapter ‘Specifications’)

The two AES/EBU inputs on the VX222e-Mic allow:

- recording of a digital signal on the AES/EBU data input; this input is
also used as source of synchronization with a digital clock

- recording of a digital signal on the AES/EBU data input, synchronized
on a digital clock connected to the AES/EBU synchronization input;

- the synchronization of analog recording and playback on an AES/EBU

clock connected to the AES/EBU Sync input.
The selection of the digital input excludes the selection of the analog
inputs.

Main software features

• Real-time, simultaneous PCM record and playback (8, 16 and 24 bits),

Float IEEE754 (with 24-bit fixed-point dynamic range)

• When using the np SDK, real-time on-board mixing of several PCM

audio streams, direct monitoring, level adjustment, panning, cross-fades,
punch-in/punch-out, scrubbing

• Possibility to control the parameters of the inputs and outputs (gains,

mutes, 48 V switch, analog compressor-limiter-expander parameters),
from the provided ‘Digigram Hardware Settings’ application, or from any
application that addresses these controls

• 24-bit DSP effects in playback and recording: 3-band parametric

equalizer plus Maximizer

• Low latency DirectSound, ASIO, and Wave

∗∗

drivers

Note: the HR Runtime package for Windows Vista does not include a Wave

driver. In case your audio application explicitly requires a Wave
interface, a Wave driver is available on request. In this case, please
contact Digigram

.

HARDWARE REQUIREMENTS

Minimum requirements

PC with one free PCI EXPRESSTM (PCIe®) slot (x1, x2, x4, x8, x16 or x32).
CPU power and memory required depend on the operating system and on the
audio application used.

Software requirements

To use your VX222e or VX222e-Mic, install the driver from the HR Runtime
package version 1.70 or higher. This package includes:

• a Digigram np driver enabling OEM applications to best capitalize on the

boards

• a WDM DirectSound driver

• a Wave driver

∗

(32 bits, installation optional)

• an ASIO driver (32 bits, installation optional)

Supported operating systems

VX222e and VX222e-Mic cards run under Windows XP, Windows Vista,
Windows Server 2008, and Windows 7.

HARDWARE INSTALLATION

Due to the reduced length of the PCI EXPRESSTM bus connector and the
resulting lack of mechanical stability, we strongly advise against transporting the
card(s) installed in a computer, unless its chassis or case provides a dedicated
support to keep the card securely in place in order to avoid physical damage.

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

Installing the card

Gently plug the card into a free PCIe

®

slot and press it down firmly to position

it. Tighten the screw.

Interrupt and memory address

Hardware interrupt and addresses are automatically set up at start-up by the
PCI PnP BIOS.

∗ Windows XP and Server 2003 only; for Windows Vista, a Wave driver is available on

request.

SOFTWARE INSTALLATION

Note: the installation of the software 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, it might require the use of a specific driver version. In this case, make
sure that the updated driver has been approved by your supplier.

Standard installation under Windows XP,
Windows Server 2003, and Windows Vista

If the driver has been downloaded from our web site, it has to be expanded
prior to the driver’s installation as follows: double-click on the downloaded
file (self-expanding). You can use the default destination location (Windows
temporary folder) or select another directory.

Important note

: this default procedure installs the ‘Digigram Hardware Settings’
control panel. This application allows the configuration of the hardware resources of
Digigram cards for all audio applications. The DHS allows for instance to define the
clock of the card, the input source, input and output analog and digital gain,
Sample Rate Converters, digital output format, etc...

Please note that, with the DHS installed, controls available through the DirectSound
control panel are limited to:

• Volume control for input and output

• Wave control

Under Windows XP, and Server 2003 you may also install the driver without
installing the DHS control panel, and in this case more controls are available
through the DirectSound

control panel:

• Volume control for input

• Wave control

• Monitoring control

• Analog input level

• Digital input level

• Clock selection: AES Sync, AES1, Word Clock

• Digital output format: professional, consumer
