Automaticity input selection

The QueBec Pro has a built-in automatically input selection mechanism that ensure that the  

latest active input connected to the Quebec Pro will be selected as the active one.

The way QueBec Pro works can be compared to a LIFO (Last in, first out) buffer. The only differ-

ence is that if an input no longer is active it will be removed from the “LIFO buffer”. 

Connected order

Fallback order

If the VGA input no longer is active it is simply removed from the “buffer” giving a new fallback 

order like this.

The QueBec Pro make sure that when changing between VGA and HDMI input the device being 

controlled will have the right input selected.

If you bypass the automaticity input selection and select an input that is not active, this will be 

added to the “LIFO buffer” the same way as if an active signal is detected. In case an inactive 

input is manual selected and another input become active the system will jump to this input.
