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 and occurs

whether or not there is a live signal present on the input.

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 0.3 or 5 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.
