When you install the optional
Audio
mezzanine, the ImagePRO-II can process both digital
and analog audio. With this option, you can:
•
Process a video signal that contains embedded audio, on any output that supports
audio
•
Associate external audio with an input and play it on any output that supports
audio
•
Associate one audio source for all inputs, or associate separate audio sources for
each input and play it on any output that supports audio
•
Process audio on a per-channel basis
•
Map audio to a logo or internal black
•
Mute the audio
When the input video contains embedded audio, the ImagePRO-II disembeds the audio for
processing. The audio can then be routed to any output that supports audio, including the
25-pin I/O connector on the optional rear-panel Audio mezzanine shown in the following
illustration.
Figure 4-111.
ImagePRO-II Audio Mezzanine
Using this mezzanine, you also can import external audio and use it on any output that
supports audio. The Audio mezzanine provides eight channels of digital AES/EBU inputs
(four pins of two channels per pin), two channels of analog input, eight channels of digital
AES/EBU output (four pins of two channels per pin), and two channels of analog output.

The following inputs and outputs support audio processing: HDMI, DisplayPort, SDI1, SDI2
(with the 3D/Dual Channel option installed), and the 25-pin I/O connector, which processes
both analog and digital AES audio.
Analog and DVI video cannot contain embedded audio. However, you can associate these
inputs with the external analog or digital audio inputs from the Audio mezzanine.
The Composite output cannot process an audio signal.
