Overview of the Vertigo XG’s Hardware
Audio input/output channels
The Vertigo XG supports both embedded and discrete audio channels. Each video
input/output can contain up to 8 stereo pairs (16 channels) of embedded audio.
The number of discrete audio input/output channels depends on the number of physical
inputs available. For each physical input available there will be a discrete audio breakout
cable (see figure
2-5 ). Each discrete audio breakout cable contains 4 BNC inputs and
8 BNC outputs. Each BNC connector represents 1 stereo pair (2 channels) of digital
AES/EBU audio. Therefore, each discrete audio breakout cable contains 4 stereo pairs
(8 channels) of input and 8 stereo pairs (16 channels) of output.
Figure 2-5. Vertigo XG’s discrete audio channels
When capturing audio, the Vertigo XG can capture embedded and discrete simultaneously,
however there are restrictions. The stereo pair cannot be captured from both sources at the
same time. For example, if only capturing pairs 1 & 2 from embedded, then pairs 1 & 2 are
not available from AES, but 3-8 are available.
The Vertigo XG performs one-to-one passthrough of audio. All captured audio will be
broadcast on the corresponding outputs. For example, if the first 2 stereo pairs of
embedded audio on SDI IN A are captured, then the signal will be output as the first 2 stereo
pairs of embedded audio on SDI OUT A and simultaneously on AES discrete outputs 1 & 2.
