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 card 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 card 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 card.

which means it can be plugged in 5 V keyed PCI slots as well as in 3.3 V
keyed PCI slots. The card is also compatible with PCI-X interfaces.

Main hardware features

2 balanced∗ analog mono line inputs
2 servo-balanced∗∗ analog mono line outputs, with software

programmable analog and digital gain

1 digital AES/EBU

∗∗∗

stereo input.
(The selection of the digital input for recording excludes the selection of the
analog inputs)

1 digital AES/EBU

∗∗∗

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.

Main software features

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

mutes, 48V switch, analog compressor-limiter-expander parameters),
from the provided wave mixer application, or from any application that
addresses the wave mixer controls.

24-bit DSP effects in playback and record:
3-band parametric equalizer and maximizer.
