This DLA-X55R projector, and its essentially identical twin (but for some trim), the DLA-RS48 projector , is the third generation in this larger box (and sporting 3D). The projector is definitely a size larger than my own JVC RS20, and is at least as large as just about any other under $10,000 projectors.
Everything is motorized, which means zoom, lens shift and focus. The 2:1 zoom lens is center mounted, and recessed, The otherwise shiny black piano finish of the projector is only interrupted by the gold trim ring around the lens, gold lettering, etc. Elegant looking, though large compared to most projectors that pass through here.
The JVC DLA-X55R's indicator lights are on the top front to the left of the lens (if you are facing the projector). In addition to the lens, the front also houses the front Infra-red sensor for the remote control. (There's a second one in the back.)
Four screw thread adjustable feet are located on the bottom of both the X55R and DLA-RS48 projectors.
As to connectors, there's a pair of HDMI 1.4a inputs, and a LAN connector on the top row. Below is an RS232 serial port for command and control. Next over, three color coded RCA jacks for component video, and then a DIN S-video jack. On the third row, the left hand side has the Din connector for the provided 3D emitter. An analog PC input (HD15) is next. (The lower cost X30 and RS45 lack a dedicated standard computer input.) Further over are a screen trigger, and a jack for hard wiring the remote control. That's it but for the power receptacle.
There is, of course, a control panel on the projector. Instead of on top, where a majority of projectors have their control panels, JVC has placed the control panel for the DLA-X55R (and the other new RS and X series projectors) in the center of the back panel of the projector. That's right next to the inputs and other connectors. For most, that's just fine. If you are shelf mounting, however, with minimum rear space on your shelf, getting to the control panel will be essentially impossible, so don't misplace the JVC X55R's remote control.
