12 SID-X1N - Principles of Operation
6 Principles of Operation
This chapter describes the principles of operation of the SID-X1N and comprises:
• Video input selection (see Section 6.1
)
• Audio signal control (see Section 6.2)
The SID-X1N selects video and audio inputs based on the rules described below.
6.1 Video Input Selection
The video mode selection is set by the DIP-switches (see Section 8.1) to either of
the following:
• Manual
• Last connected
In manual mode the input is selected using the front panel buttons. Only inputs
with a live signal present can be selected.
In last connected mode the SID-X1N selects the input based on which input was
connected last. If the signal on this input is subsequently lost for any reason, the
input with a live signal with the highest priority is automatically selected. The
priority from highest to lowest is:
• HDMI
• DisplayPort
• DVI
• PC
Note: In last connected mode, manually selecting an input using the front panel
Input Select button overrides the last-connected automatic selection.
When an input cable is removed, there is a delay of either 0.5 or 3 seconds,
(selectable, see Section 8.1
) before automatic switching takes place. After that,
another input can be automatically selected according to the signal priority shown
above.
