D-73d Series Installation/Operation Manual 7
The D-73d Series LED 3-D Home Theater Projection System consists of the following
components:
• The projector, consisting of two discrete LED optical engines stacked one on top of
the other to provide either two-dimensional (2D) or three-dimensional (3D) content.
• The DC-300 Dimension Digital Controller™ unit that provides “left-eye” and
“right-eye” video signals and the on-screen display (OSD) menu to the projector. In
addition, the Dimension Digital Controller controls the projector in response to user
input via its infrared (IR) remote control unit or front-panel keypad, an external
control system or HDMI Consumer Electronics Control (CEC) messages.
Figure 2-1 shows how these components connect to and interact with each other. The
following sections describe each one in detail.
