provide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions contained in this data sheet, may
cause harmful interference to radio and television communications. However, there is
no guarantee that interference will not occur in a particular installation.

If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:

* reorient or relocate the receiving antenna
* increase the separation between the equipment and the receiver
* connect the equipment into an outlet on a circuit different from that of the receiver
* consult the dealer or an experienced audio television technician.

Note: Connecting this device to peripheral devices that do not comply with CLASS B
requirements or using an unshielded peripheral data cable could also result in
harmful interference to radio or television reception. The user is cautioned
that any changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate this equipment. To ensure
that the use of this product does not contribute to interference, it is necessary to use

CONTENTS OF THIS PACKAGE

Thank you for purchasing a Digigram PCX924 or PCX22
The package consists of the following components:
* a PCX924

v2, PCX924-Mic, or PCX22v2 sound card,

* the User’s Manual at hand.

The cables (optional) are delivered separately.

FEATURES

PCX924

v2, PCX924-Mic, and PCX22v2 are audio cards for PCI bus. They are

‘Universal PCI 32-bit/33 MHz’, which means they can be plugged in 5 V PCI
slots as well as in 3.3 V keyed PCI slots. The cards are also compatible with
PCI-X interfaces.

Main hardware features

PCX924v2 and PCX924-Mic

• 2 balanced analog mono line inputs, with:

- Software programmable analog and digital gain

- Input impedance selection (600 Ω, >10 KΩ) via switches on the card
(see top cover of the card)

• 2 servo-balanced
programmable analog and digital gain

• 1 digital AES/EBU

• 1 digital AES/EBU

These two AES/EBU inputs allow:

- recording of a digital signal on the AES/EBU synchronization input

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

- synchronization of analog record/playback on an AES/EBU clock
The selection of the digital input for recording excludes the selection of
the analog inputs.

• 1 digital AES/EBU
Always plays the digital version of the analog outputs 1 and 2.

PCX924v2 , PCX924-Mic & PCX22v2

User’s Manual

• 1 CD-ROM input

• 1 SMPTE-LTC (longitudinal time code) input

• Variable programmable sampling clock, from 8 kHz to 50 kHz .

• 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

If this connector is not used, synchro switches must be ON.
If it is used, one of the connected cards must have the synchro switches
ON, all the other linked cards must have the switches OFF.

PCX924-Mic additional hardware features

• 1 microphone input with switchable 48 V phantom power, and analog
expander/compressor/limiter
This input and the line input are mixed together before analog to digital
conversion.

Main software features

PCX924v2 and PCX924-Mic

• Decoding and mixing of several PCM (8, 16 and 24 bits) and MPEG
Audio streams (Layer 1, II & III)

• Real-time, simultaneous record and playback in PCM (8, 16 and 24 bits)
as well as in MPEG Audio layer I and layer II

HARDWARE REQUIREMENTS

PCX924v2, PCX924-Mic, and PCX22v2 cards have been developed for IBM and
IBM-compatible PC systems.

Minimum requirements

• Pentium III minimum (or equivalent)

• 128 MB RAM

• One free PCI slot (5 V or 3.3 V)

SOFTWARE REQUIREMENTS

To use your PCX924v2 or PCX22v2 card, you have to install the driver from the
np Runtime package version 6.01 or higher.

The PCX924-Mic requires the installation of np Runtime version 6.30 or
higher.

These packages also include a Wave driver that may be installed so that the
card can be used with standard multimedia applications.

User’s Manual

Supported operating systems

PCX924v2 and PCX22v2 cards run under Windows 98 (SE and Millennium),
Windows 2000, and Windows XP, the PCX924-Mic under Windows 2000
and Windows XP only.

HARDWARE INSTALLATION

Note: Under Windows 2000 and XP, the card has to be installed in the
computer prior to installing its driver.

Under Windows 9x, first install the driver, and then insert the card.

Installing the card

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

Interrupt and memory address

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

WARNING

The PCX924-Mic includes a microphone pre-amplifier, which is sensitive to
electro-magnetic perturbations.

In order to avoid spurious noise when using the microphone input, we
recommend not to install the PCX924-Mic close to another card equipped
with a fan. If this happens try to have some free slots between the two cards.
