1. System Introduction
The Espedeo™ PM-2000A is a standalone passive 3D Polarized System specially developed for digital
cinema projectors. Featuring flexible and easy installation, the system can automatically switch to the
corresponding operating position by identifying 2D and 3D signals. Equipped with specified polarized
glasses, the PM-2000A is able to present stunning and brilliant 3D images.
1.1.Key Features
▪Easy Installation
The system can be installed right in front of digital cinema projector by simply using the bracket
delivered along with the system itself.
▪Simple Connection
The entire system is simply connected by two connection cables with the digital cinema projector
and motorized bracket.
▪2D-3D Switching
The polarizer automatically identifies 2D/3D signals. It automatically moves to the front of the lens
while playing 3D images and automatically moves to the standby position when playing 2D images
or system is idle.
▪Easy Maintenance
The polarizer can be cleaned and maintained in an easy and fast manner. In addition, the polarized
glasses can be directly replaced if there are any damages of the polarized glass that affect
projection quality.

4.1.Polarizer
Figure 2: Polarizer
The dimensions of the polarizer are approximately 234 x 211 x 25mm and its weight is about 1.3 kg.
NOTE
The polarizer is a major optical component of the PM-2000A system. Ensure that it is handled it care
during system installation.

4.3.Motorized Bracket
Figure 4: Motorized Bracket
▪The motorized bracket is a passive 3D system apparatus for automatic switching between
3D/2D playing.
▪Installed on top of the bracket support base, the motorized bracket connects to the polarizer
through the DB9M/9F motor signal cable. When the digital cinema projector is playing 3D movie,
the polarizer automatically moves upward to the front of the lens to polarize light paths. When
the digital cinema projector is playing 2D movie, the polarizer automatically moves downward
from the front of the lens.
▪The motorized bracket works with the adjustable bracket extension kit to adjust the position of
the polarizer.
4.4.Bracket Support Base
Figure 5: Bracket Support Base
The bracket support base is placed in front of the digital cinema projector which is used to fix the
position of motorized bracket. The height of the legs can be adjusted to fit various installations.
Moreover, two sets of screw holes are used to fix the bracket for the alternative, as shown in Figure 5.
NOTE
Please ensure that the distance between projector lens and the polarizer is within 15cm after the installation.
