16.1.4 Audio-extension Card

The audio-extension card and audio cables are part of the X.mio series break-out box

or the X.mio series cable kit (that comes with the X.mio series boards), and needs to

be installed when AES / EBU audio support is required. The card is an extension for the

connectors, and does not provide any extra functionality. For installations that require

embedded audio, or no audio at all, this extension is not required.

IMPORTANT! The Matrox audio-extension card only supports digital audio.

By default the audio-extension card will consume one additional free slot on the

motherboard. The card is supplied with the Matrox X.mio series boards in terms of

power and data.

In some cases the design of the audio-extension card makes it hard to mount it at a

location with an underlying PCIe slot. Therefore it is an option To remove the audio-

extension card back-end instead of using another PCI or PCI-X slot. However, it is in

most cases possible to mount the extension card in any slot in the machine, unrelated

to the underlying slot’s design, without removing its back-end.

Removing the back-end of the extension card will free any connection to the

motherboard. As a result it may react more sensitively to transportation and

tension introduced by the external audio cables connected to it. Therefore, the

above-mentioned procedure should only be applied to machines residing in stable

environments like a dedicated machine room. Do not apply these instructions to

machines intended to be used for outside broadcasting ( OB ) or equipment that will be

moved around a lot.
