On the X.mio2/2 Plus breakout box, each of the two audio bays, A and B, consists of
four female BNC audio input channels and of eight female BNC audio output channels.
Note: Bay cables are not included.
On the backside of each breakout box there are two connectors labeled AUDIO-A and
AUDIO-B. The included cables are used to connect the corresponding plugs of the X.mio
series Audio-extension Card to the computer.
Audio connectors for X.mio
The front side of the X.mio breakout box hosts various audio in- and outputs. Each of
the two audio bays, A and B, consists of two female AES / EBU audio input channels
and of four male AES / EBU audio output channels.
16.1.2 Video Cable Assignment
Connect the relevant video input(s) and output(s), and the reference signal(s)
according to the labeling on the cables.
SDI Out connections are only relevant when the Matrox board is used for SDI In and
Out.
A reference signal can be attached to the reference input connector (Analog Ref. In)
which can be fed with any analogue GenLock signal such as a Blackburst signal or a Tri-
level sync as required.
If you are relaying the reference signal (for synchronization) from Matrox X.mio and
X.mio2 to a graphics card (e.g. NVIDIA) you must verify that all internal connections
between the graphics card and its SDI extension is OK and that the extension is
properly supplied with power.
When using the Ref. In connector on the Matrox X.mio and X.mio2 boards for
synchronization, the Ref. Out Loop connector must be terminated with a 75 Ohm
resistor unless it is being used to loop an incoming GenLock signal. The Ref. Loop for
the X.mio2 Plus is terminated by default, and thus only supports Ref. In on the actual
board (see Video connectors for X.mio2 Plus).
