The CH-322 3D Demultiplexer is a device used to separate a 3D signal into it's left and right signals for sending to two 2D projectors. The 3D signal must be sent via a 1 to 2 Distribution amplifier (such as the QU-12S) and each of the two 3D signals must be passed through a CH-322 whereby the left or right signal can then be outputted to be passed through to each of the two 2D projectors. When alighted correctly, the two 2D projectors can then display each signal to produce a 3D image which can be viewed using polarized 3D glasses.
In addition, the CH-322 can convert 3D signals to 2D for use with 2D screens. The device automatically detects the 3D or 2D content, and checks if 3D content is in either Side-by-Side or Frame Packing format.
