The THEATRE System Centerpiece
The DreamScaler3 Theatre features a new software and two additional 12V outputs to compute the video
anamorphism pre-processing and to drive the Theatre Anamorphic Lens position.
The DreamScaler3 Theatre centralizes the controls and automation commands of the THEATRE System for a
unique, unexpectedly simple to operate 2.35:1 theatre experience.

12V Trigger #2
This menu controls the state of the 12 Trigger #2 output located at the back of the DreamScaler3 Theatre. The
options are:
•
ON: the 12V Trigger #2 is active and can output up to 250 mA at 12Vcc.
•
OFF: the 12V Trigger #2 is inactive and is set to 0 Vcc.
•
THEATRE: this option gives to the DreamScaler3 the full control of the 12V Trigger #2 states. See “Configure the
DreamScaler3 THEATRE for the THEATRE System”, page 41 to configure the DreamScaler3 in THEATRE
Mode.

Lens
The Lens Aspect Ratio menu defines the presence or not of an anamorphic lens into the projection system. The
options are:
•
Mode 1: the picture is vertically stretched by a factor of 1.33 (vertical zoom of 133%) to eliminate the black bars
from the projected picture. This mode is also frequently referenced as Constant Image Height (CIH) because
when the Anamorphic Lens is installed the projected image would have the same height.
•
Mode 2: the picture is compressed horizontally by a factor of 1.33. (horizontal zoom of 75%). This mode is also
referenced as Constant Image Width (CIW) because once the Anamorphic lens is placed in front of the projector
beam, the projected picture would have the same width.
•
Mode 1 - Auto: this option triggers 3 simultaneous actions.
1) Apply the Mode1 video processing (horizontal stretching by a factor of 133%) when the selected Input Active
Aspect Ratio is large enough (Active AR must be set to 2.33:1 or higher).
2) Switch the 12V Trigger #2 to 12Vcc if the 12V Trigger #2 is set to THEATRE Mode.

12V Trigger Level
The 12V Trigger outputs can be programmed to operate at normal or negative logic. The options are:
•
Normal: when the 12V trigger is active, the output level is 12Vcc, when inactive the outputs is set to 0 Vcc.
•
Negative: when the 12V trigger is active, the output level is 0Vcc, when inactive the output is set to 12Vcc.
12V Trigger #1 state is determined by the state of the DreamScaler3. When the DreamScaler3 is switched ON, the
12V Trigger #1 is active, when switched OFF or in standby mode, the 12V Trigger #1 is inactive.
12V Trigger #2 is a programmable output that can control the Theatre Anamorphic Lens position.

Theatre Mode, Frame and Active Aspect Ratios
The Theatre Mode is a new automation process that determines the Anamorphic Lens position (in or out of the
projector beam) depending on the Frame Aspect Ratio and Active Aspect Ratio values.
The Aspect Ratio is the width divided by the height. The Frame of a picture is the whole picture projected, that
includes the vertical or horizontal black masking. The Active part of a picture is the effective portion of the Frame.
Examples of 16:9 video sources with different Active AR:
The following sources use 16:9 Frames, and when the Active AR is larger than 1.78, the content is letterboxed into
the 16:9 Frame
