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.

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

IMPORTANT NOTICE

This card has been tested and found to comply with the following standards:

• International: CISPR22 Class B.

• Europe: EMC 89/336/CEE (1992) specifications.

• United States: FCC Rules-Part 15-Class B (digital device).

In order to guarantee compliance with the above standards in an installation, the
following must be done:

• the provided cable must not be modified.

• additional cables used must have their respective shield connected to each

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 shielded I/O cables.

CONTENTS OF THIS PACKAGE

Thank you for purchasing a Digigram PCX924 or PCX22v2 card.
The package consists of the following components:

• a PCX924HR, PCX924HR-Mic, or PCX22HR sound card,

• the User’s Manual at hand.

The cables (optional) are delivered separately.

FEATURES

PCX924HR-Mic, PCX924HR,and PCX22HR are audio cards for PCI bus. They
are ‘Universal PCI 64-bit/66 MHz’, which means they can be plugged in 32­bit/33 MHz 5 V keyed PCI slots as well as in 64-bit/66 MHz 3.3 V keyed PCI
slots. The cards are also compatible with PCI-X interfaces.

PCX924HR & PCX924HR-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
gain and a maximum output level of +24 dBu

• 1 digital AES/EBU
This input features a hardware sample rate converter (for details see

chapter ‘Specifications’)
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 Sync input

• These two AES/EBU inputs 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 inputs, synchronized
on a digital clock connected to the AES/EBU synchronization input;

∗∗

analog mono line outputs, with software adjustable

∗∗∗

stereo input

∗

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

User’s Manual

- the synchronization of analog recording and playback on an AES/EBU
clock connected to the AES/EBU Sync input.

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

• 1 LTC (Linear Time Code) input

• 1 mini jack stereo headphone 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

PCX924HR-Mic
Additional hardware features

• 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.

• The AES/EBU input is AES42 compatible (for details see chapter
‘Specifications’)

Note: AES42 is an extension of the digital audio standard of interface AES3 providing for

interfacing digital microphones.

PCX924HR, PCX924-Mic, and PCX22HR
Main software features

• Decoding and mixing of several PCM (8, 16 and 24 bits) and MPEG
Audio streams (Layer 1, II & III, up to 48 kHz sampling frequency)

• Real-time, simultaneous record and playback in PCM (8, 16 and 24 bits),
Float IEEE754 conversion (with 24-bit fixed-point dynamic range), as
well as in MPEG Audio Layer I, Layer II, and Layer III

• When using the np SDK, direct monitoring, level adjustment, panning,
cross-fades, punch-in/punch-out, scrubbing, time-scaling, inter-board
synchronization, synchronization on LTC (SMPTE)

• 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, Wave, and ASIO drivers
