As if to live up to the "Pro" moniker, the Deuce Pro is considerably larger than the Deuce; designed to occupy one rack unit, it is more than twice as wide and almost twice as deep. The back panel is festooned with input and output connectors for video, audio, and power. The front panel contains all of the unit's control buttons, as well as LEDs providing visual feedback of selections. The buttons are "chiclet"-style rubber keys, a major improvement over the membrane buttons found on the Deuce. There are also more of them--12 compared to the Deuce's stingy four.
