For 3Play 4800, the next tabbed pane in Output Configuration is labeled Aux.
ANALOG OUTPUT TYPE
The third connector row in the VIDEO OUT group on 3Play’s backplate is likewise labeled AUX. The sole configuration option for AUX governs its analog video connection type.
The same options we discussed above under the sub-heading Analog Output Type are offered. For HD sessions, Type is automatically set to Component. For SD sessions, the Component or Y/C + Composite connection type options are available.
Note: The video stream displayed on AUX is determined by the Channel Delegate active on the Control Surface at the moment. Video from the delegated channel is also sent to Aux.
