Image of the following product: Dual Projection Solution


A choice of Side-by-Side and vertically-configured Double Stack projection systems, employing dual SRX-R320 Series projectors plus specially-adapted Doremi IMB-SA server

Sony offers dual projection solutions that are specifically designed to provide outstanding Sony 4K picture quality with high brightness in 3D or 2D on the largest cinema screens.

The DCI compliant systems employ Sony’s industry-leading SRX-R320S and SRX-R320 projectors, matched with the Integrated Media Block (IMB) and ShowVault cinema server from Doremi Labs.

The systems can be configured with dual projectors either ‘Side-by-Side’ or for vertically-aligned ‘Double Stack’ operation. This gives flexibility for cinema operators to select the ideal configuration to suit space available in the projection room.

Cinema operators can select the appropriate SRX-R320 Series projectors to match their preferred choice of 3D technology:
SI-R320S-SS – Side-by-Side configured dual projection solution, for use with the Sony 3D polarising system
SI-R320S-DS – Double Stack (vertically-configured) dual projection solution, for use with the Sony 3D polarising system
SI-R320-SS – Side-by-Side configured dual projection solution, for use with the RealD polarising system
SI-R320-DS – Double Stack (vertically-configured) dual projection solution, for use with the RealD polarising system


Bright, highly immersive cinema experience

The Sony dual projection system can be operated in a choice of 2K and 4K modes, depending on installation conditions. Dual projector mode gives high-brightness projection at 2K resolution for 2D onto a white screen, and 3D images on a silver screen. 2D at 4K resolution can be employed for single-projector operation onto a silver screen.

High brightness on screens up to 25m

Optimised for large-sized cinemas, the dual projector configuration delivers up to a total 40,000 lumens (with 4kW lamp in each projector), achieving SMPTE brightness levels of 14 ft-L on screens up to 25m* wide (gain 1.8). The projectors are compatible with Xenon lamp bulbs from a number of recommended manufacturers.

Flexible configuration

Dual projectors can be configured either Side-by-Side or vertically aligned for ‘Double Stack’ operation. This gives flexibility for cinema operators to select the ideal configuration to suit space available in the projection room.

Includes Doremi Integrated Media Block (IMB) and ShowVault cinema server

The Doremi ShowVault server/storage unit interfaces directly with the Doremi Integrated Media Block (IMB). Installed within the FIPS protected zone of the projector chassis, the IMB carries out DCP decryption, separation of image and audio data and decoding of compressed image data. The Doremi IMB is customised to transfer image data to the projector head using the appropriate Sony image data format. The IMB-SA system includes a 4K license*, allowing full quality playback of 4K DCPs and well as 2K DCPs. The Doremi server system is controlled via a supplied 15” touch screen, or remotely by the cinema’s Theatre Management System via a network connection.

Optional Dolby® Atmos™ capability

The Doremi IMB-SA gives operators the option to add a Dolby Atmos playback license for immersive multi-channel cinema sound.

Increased local storage capacity

The Doremi IMB-SA system includes the ShowVault-4 server that provides approximately 4TB of usable storage (6TB total). This high server capacity gives cinema operators greater flexibility to show different movies programmes for morning, afternoon, evening and late shows.

Displays 4K and 2K cinema files and HD alternative content at highest possible quality

The dual projection solution can store and display both 4K and 2K DCI compliant cinema files* as well as HD video via its Alternative Content input. 2K and HD alternative content is automatically up-converted by the projector to display 4K equivalent images on screen.

Flexible Alternative Content input configuration

The dual projection solution is fitted with an HDCP-compatible HDMI input and HD-SDI input as standard. This enables the projector to accept dual-link HD-SDI (4:4:4) and HD-SDI (4:2:2) alternative content inputs.

Comprehensive DCI-compliant security measures

The projector body structure forms a security enclosure specifically developed to comply with the FIPS-140/2 physical security and anti-tamper requirements as specified by the DCI.

Easy operation with familiar Doremi GUI

System control uses Doremi Labs’ standard GUI that’s customised to add control of Sony SRX-R320 Series projectors. Minimum training is required for staff in cinema complexes where other Doremi server systems are already installed.
