This is a picture of the dual Barco projectors which are used for 3D viewing. There is a single Barco projector just on the other side of these which is used for 2D movies. There is multiple terrabyte storage for these projectors.
Here is the Auro sound system from Cinemark XD at HHC. They use the Crown I-Tech 5000 series amplifiers (2500W @ 4 ohms).
Here is the projector console. Note how virtually everything (including ceiling tiles) is painted black. I’m sure it’s to keep any light reflections to a minimum. Everything can be controlled from here.
