INFORMATION FOR THE USER

This device complies with part

15 of FCC rules. Operation is subject to the following two

conditions: (

1) This device may not cause harmful interference, and (2) This device must

accept any interference received, including interference that may cause undesired
operation.
This equipment has been tested and found to comply with the limits for a CLASS B digital

device, pursuant to Part

15 of the FCC Rules. These limits are designed to 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
shielded I/O cables.

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.

CONTENTS OF THIS PACKAGE

Thank you for purchasing a Digigram PCX sound card.

The package consists of the following components:
* a PCX881HR or PCX882HR sound card

* the User’s Manual at hand

The cables are not part of this package. They are delivered separately.

Also available:
2U 19-inch breakout box allowing straightforward and secure connection to all

the cards’ I/Os.

FEATURES

PCX882HR and PCX881HR are audio cards for PCI bus. They are ‘Universal
PCI 64-bit/66 MHz’, which means they can be plugged in 32-bit/33 MHz 5 V
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.

PCX881HR main hardware features

• 4 AES/EBU∗ stereo inputs, with hardware sample rate converters (up to 96 kHz)

• 4 AES/EBU

∗

stereo outputs (up to 192 kHz)

• 1 AES/EBU∗ stereo sync input (up to 192 kHz in play and record)

• 1 standard Word Clock input (up to 96 kHz)

• 1 standard Word Clock output (up to 96 kHz)

• 1 video sync input

• 1 SMPTE/LTC (Linear Time Code) sync input

PCX882HR main hardware features

All features of the PCX881HR, plus:

• 8 balanced

∗∗

analog mono line inputs, with software programmable analog

and digital gain

• 8 servo-balanced

∗∗∗

analog mono line outputs, with software

programmable analog and digital gain

• 192 kHz / 24-bit converters

• Maximum level on analog inputs and outputs: +24 dBu

Note: The digital outputs always play the digital version of the corresponding analog outputs.

The selection of an AES/EBU input excludes the selection of the corresponding analog
inputs. Nevertheless, it is possible to simultaneously record AES and analog inputs, as long
as the channels are different.

Main software features

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

well as in MPEG Audio Layer I, Layer II and Layer III

L

, Float IEEE754

conversion supported (with 24-bit fixed-point dynamic range)

• When using the np SDK, real-time mixing of several PCM and MPEG

audio streams, direct monitoring, level adjustment, panning, cross-fades,
punch-in/punch-out, scrubbing, time-stretching, pitch-shifting, 3-band
parametric equalizer, maximizer, format and frequency conversions

• Low latency DirectSound, Wave

, and ASIO drivers. Under DirectSound
and ASIO, the cards operate in PCM mode only (nevertheless, an
application can integrate coders/decoders on the host PC). Under Wave,
HR boards can operate in both PCM and MPEG (layer 1 and layer 2).

L

MPEG Layer III play-only on DSP;

MPEG Layer III recording on the host computer is available through Digigram's
PC Codec option using the np SDK

∗

can be used as S/PDIF interface as well

∗∗

can be used with unbalanced signals

∗∗∗

Electronically servo-balanced outputs provide automatic level adjustment to accommodate

either balanced or unbalanced lines
