The KXO-Dual3 cards are output cards that can be installed in a Kaleido-X multiviewer. They are dual-head output cards, meaning that they support two independent outputs. These outputs, called Head 1 and Head 2, are each provided with a complete set of connectors.

The KXO-Dual3 are multi-function cards that perform a significant portion of the signal processing required to create the monitor wall output. They incorporate a mezzanine card mounted on the component side. Each output card is complemented by a rear panel (KXO-Dual-R) that holds all input and output connectors associated with the card.

Output cards can be installed in any of the two available OUTPUT slots inside a Kaleido-X frame. These slots are color-coded YELLOW on the front and rear panel of the frame.
