3.8.2 Signal Flow Through the Router
The Sirius 830 routes video and/or audio signals by using the video and audio crosspoint
modules. The Sirius 830 can be fitted with either Multiviewer outputs or Input/Output
monitoring as required (Figure 9).
Multiviewer Outputs
If the Multiviewer Crosspoint Module is fitted it receives signals from the input modules after
any processing has been carried out.
Input/Output Monitoring Outputs
If an Input/Output Monitoring Module is fitted each monitoring output can be independently
configured to display either an input or an output signal. Each monitoring output can also be
independently configured to display a signal before or after processing has been applied to it
(processing modules only).
Up to four monitor signals are passed to both the BNC and DIN 1.0/2.3 connectors on the
1237 rear monitor module (see section 13.2.2). The BNC connectors are optimized for video
signals (including embedded audio) and the DIN 1.0/2.3. connectors are optimized for
discrete audio signals.
